4:49 pm	The Battle Between Laptop and Notebook When it comes to choosing a cheap laptop or notebook, there is one thing to be certain of, there is so much debate between everyone whether a laptop and notebook are the same or completely different. On one side of the debate, you have many experts agreeing that the two are completely different. Going by the concept that a laptop is a portable computer while, a notebook is for taking notes, they will argue the point until your eyes cross, pointing out all sorts of things like a notebook is defined by many different companies as having different options from the type of processor, to the RAM, and even the optical drives. When you look at this concept, a notebook would be a veritable note taking machine which has no problems what so ever running word processing capabilities, internet access and can even come with an optical drive for means of storing data. On the other side of the table you have the laptop, which of course has more processing capabilities as well as RAM and have no problems running multimedia programs as well as high-end development software like CAD or even Dreamweaver and Photoshop. However the concept them becomes even more confusing when you start to realize that some computer companies use the terms loosely and call all of their portable computers one or the other. Some even separate them based on their capabilities and as a result a long standing debate has developed between experts in the field as to whether they are the same exact thing or completely different. According to the first set of experts, if you are looking for a cheap laptop notebook, you go with the notebook because it has less features which makes it cheaper. On the other hand since many companies call them either one or the other, this will make the decision process that much harder. Instead of thinking whether you want a cheap notebook or laptop, you should instead think about the features you need in the particular mobile computer and just look for one that is affordable and has all the features you need. Do not allow yourself to get dragged into this debate, it is not worth all of the effort, just think of it as a mobile PC and nothing more. Otherwise you could spend many days looking for a cheap notebook or laptop when in fact you need the other one. Save yourself some hassles and sit down to think about what it is exactly you plan on using the laptop for and go from there. Once this part is out of the way, finding a cheap notebook/laptop will be a much easier task because you know what you need and can then compare prices looking for the cheapest, without having to give up any features.

2:00 pm	why is my computer so slow, let's speed it up! We use computer a lot, and sometime we have emergency things to resolve, but our computers do not coorperate, so we are usually wondering "why is my computer so slow"? Looking to speed up laptop computers overall performance? Well you have come to the right place. All computers and especially laptops slow down when they get a little wear and tear on them. Unfortunately instead of adjusting a few things, people believe they need to buy a new computer in order to increase laptop speed. This just isn't true. You can actually speed up your laptop with these three quick steps. I will also recommend a program that can perform all three automatically for you. Speeding up your laptop was never this easy! The first step is to run a disk defrag on your system. What a disk defragmenter does is increase the speed in which you can access information. Whenever your computer processes information it needs to jump from place to place and this takes time. Defragging your system allows your computer to stream information through one path. This will speed up laptop computers ability to access and run different programs. The second step is to eliminate as many unnecessary startup programs as possible. Anytime you install a new program it will try to automatically start itself every time you power your computer on. This will dramatically slow down the speed your computer can start up or shutdown. These programs also eat up valuable RAM which causes the computer to be very sluggish. Eliminate all but the necessary programs and feel the incredible difference in your laptop processor speed. The third step is to clean up registry congestion. This is without question the most important step you can take to speed up your laptop. As we download new or remove old programs our registries get congested with useless and redundant files. This clogs everything up and leaves you asking why is my computer slow? Getting rid of those unnecessary files will not only speed up your computer but prevent it from crashing in the future. These are three steps you can do right now to get your computer running like it did out of the box. If you are a computer novice and want a program to do the work for you I highly recommend visiting the link below. Instead of spending hundreds on new upgrades or thousands on a new laptop, why not just optimize your computer to reach it's peak performance for a fraction of the cost? Give it a try.

2:04 pm	Do I Really Need the Best Laptop? Depending what your need is for the laptop will determine if you really need the best of the best or one that will cover your requirements. If your just a casual surfer of the net, college student or you need a good laptop for your business, each type of person will desire something different. The person who goes on the internet just to check their e-mails or to chat with their friends will only require a basic computer with minimal amount of RAM as well as programs. They wouldn't need to get all the up grades or even fill their laptop with major amount of gigs. A college student, depending on what type of classes he or she are taking, must decide if they would want to get graphic programs or not. A big issue with students is that they want the laptop to be conveniently mobile. Some laptops are bulky and have some weight. The best college laptop is the one that works for that particular person. As for the business man or women, their needs will also vary. First of all they need one that will not fail them. They will require a dependable laptop that can be mobile as well. Since a businessperson travels quite a bit he will need to make sure that he or she gets a long life battery and a back up one as well. The programs that they'll need will also depend on what field of work they are in. In advertising one would need a laptop that has a few different graphic programs, while someone in banking would need spreadsheets and financial programs. Whatever the need there's a laptop out there for you. Making a list of exactly what you'll be doing with it and using it for will help you in your decision.

3:45 pm	For home users, which is the best laptop? We usually use laptops at office for works, but sometimes we do need laptops at home for entertainment or leisure, you will generally need a multi-purpose machine. That is, it should be capable of word processing, emailing, DVD burning and gaming. The problem, as always, is choosing the correct laptop to fit your needs. This article will show you which are the best laptops for the average home user. Overview The home user generally needs a laptop that performs a variety of functions. These range from word processing, Internet surfing, video editing and gaming. A laptop with over-the-top specifications would not be needed - just a simple one would probably be ok. We now look at 5 of these laptops I'd recommend. 1. The Fujitsu Lifebook A6120 Fujitsu has always made premium (and slightly pricey) laptops. However, the laptops are stellar performers and usually beat performance scores of other laptops. The Fujitsu Lifebook A6120 is one of the latest offerings from Fujitsu and comes highly recommended for the multi-purpose home user. 2. The HP Pavilion dv6500t Amazing laptop that is selling like hotcakes out there. The HP Pavilion dv6500t is one of the best value laptops you can get (at last check, its street price was only about $850). However, it packs in great multimedia and gaming features. Definitely a contender for the home laptop category. 3. The Gateway T-6828 One of the latest laptops to come from Gateway, the Gateway T-C90 is a good machine for the average home user. You can expect to perform most of your basic computing tasks using this laptop. Gateway is not as well-known for its laptops (compared to laptops), but this model is one of the better models to be launched. Highly recommended. 4. The Dell Vostro 1310 As you might know, Dell is one of the most popular manufacturers of laptops. The Dell Vostro 1310 lives up to the Dell name by delivering great performance at a very decent price. You should definitely check it out (in fact, order it online since Dell has good online deals for its laptops). 5. The Toshiba Satellite U405-S2830 The Toshiba Satellite U405-S2830 is a good choice for the home user as well. It costs slightly more than the Gateway T-6828, but its feature set and performance specifications certainly justify the premium in price. Conclusion You should now know which are 5 of the best laptops for the home user. Your opinions may vary, but for myself, I'd go with the HP Pavilion dv6500t as my first choice of laptop for the average home user. Until next time, happy shopping!

4:58 pm	Something about Laptop Batteries you should know Lots of people use laptop now, and they usually need to take their laptops out for work, at that time, the laptop battery becomes very important, if it does not work or works very short time, your work will be affected and even stocked. Actually if you use your notebook on the move a lot, you will notice that as time goes by, you will run out of power faster than usual. Laptop batteries are usually the first casualties of a computer’s old age. Here’s how to prolong their life expectancy and how/where to purchase a new one. One tip of preserving laptop batteries is to disconnect them from your unit if you won’t be using it for a long time. Of course by the time you switch it back on, some of the settings will have to be updated to reflect the current time. Another of the habits that should be acquired is to let the battery run out juice from time to time. According to people who know far more than I do, apparently laptop batteries have a memory and the more they are recharged when not completely dry, the more they figure that the charging point is when it has run out of power. My advice to those who fly or travel a lot is to carry at least two laptop batteries on them each time. I would even venture to add that the more you lug around, the better as sometimes you simply don’t find the time to recharge them. Oh yes, before I forget… when you recharge your laptop batteries or any batter for that matter make sure that they are charged completely according to the manufacturer’s provided guidelines. What you do with your computer while running on battery power will greatly influence how long it lasts. The more processing power computer use, the faster laptop batteries run out of juice. So, you might want to limit DVD watching or do subtle things such as closing unnecessary applications, reduce the screen’s brightness and basically focus on the single task that you turned your computer on for, in the first place. Watch out though! Make sure that you get the right battery for your laptop. Check your user guide for exact specifications. You don’t want to receive it and sadly realize that you’ve wasted your money or worse, you don’t want the thing exploding in your face. I don’t mean to scare you but lately it seems that laptop batteries are being recalled in massive numbers because they have been causing fires! Should you purchase your replacement battery straight from the manufacturer? Yes as it’s the safest bet but it will usually be more expensive for you as they don’t practice price matching. If you want to buy replacement batteries, no hesitate to click the links below, we also supply laptop ac adapters, laptop keyboards: Acer PA-1650-02(Input: AC100-240V (worldwide use) Output: DC19V 3.42A) Toshiba PA2522U battery(Voltage: 10.8V Capacity: 8400mAh ) Liteon PA-1650-01(Output: DC19V 3.42A ) Toshiba PA3420U-1BRS battery(Capacity: 4400mAh ) Acer ADP-65DB AC Adapter(19V 3.42A AC Adapter for Acer) (Comment on this)

3:59 pm	What laptop fits kids? Laptops are more and more popular now, even lots of kids are being using it now. As a father or mother, do you want to buy a laptop for your kids? Well, the truth is, It can be difficult to choose the correct model. There is a huge variety of laptops out there and any one of them could be the one for your kids. To help you decide, this article runs through some of the basic thoughts and factors to consider before buying a kid's laptop. So read on and find out more ... 1. As A Home Computer If you intent to buy the laptop as a home computer to be used by the kids and your spouse, you'd best go for a desktop replacement model. These models have widescreens and very decent processing power to allow you to use the laptop as though it were a desktop. 2. For Schoolwork If your child needs a laptop for schoolwork at the high school level, it is then a good idea to get them a budget range laptop. Usually, they would not need to access the laptop very frequently - hence all you need is a simple, budget laptop like those from Dell. For college going students, they have a greater need for a better laptop. At the college level, you'd expect your kid to lug the laptop from class to class and also do presentations. Hence, a higher end, ultraportable model would be better suited for them. 3. For Multimedia Some kids love to dabble with digital video. Some of them even post videos of their travels on YouTube or cut a DVD. If your child is such a multimedia enthusiast, then getting him or her a good laptop with Firewire support becomes quite important. 4. For Gaming Believe it or not, some kids want a laptop so they can play games. Now, in the first place, as a parent, I'd never agree to this. Particularly if they can play games on the desktop machine. However, if for one reason or another you need to buy a gaming laptop, go for those from Dell or Alienware - they sell very nice gaming laptops. 5. So Why Does Your Kid Need A Laptop? The very first question to ask yourself is why your kid needs a laptop. Is he or she a college student and about to enter college? Then a good student laptop that is portable would be ideal. Is he or she just a high school student who needs to use a laptop for class projects or research? Or perhaps if your child is a pre-schooler, does he or she even need a laptop? Would a desktop suffice? Think through these questions to understand why a new laptop is needed. Then you will be able to buy just the right one for your kid. We'll now look at some reasons why your children might need a laptop, then consider the appropriate types of laptops to buy. Conclusion I hope this article has shown you how to buy a laptop for your kids. Regardless of the signs that could signal your laptop is going into critical, degradation mode. Watch out for these signs and try to prevent them where possible - it could save your laptop before it really crashes on you. Until next time, happy computing!

10:05 am	These Laptop Accessories are Must-Have In our new days, lots of people have to go abroad for work, they are highly mobile and want a pleasant computer experience, there are a few laptop accessories that should accompany them and their notebook. Below, I will list some that I deem essential or really useful and helpful. Laptop Protection These laptop accessories will prevent your computer from physical damage, theft or data loss. It’s a tough world out there and you never know what can happen within seconds. For instance a lock will prevent anyone from snatching your laptop when going to get a coffee refill while a laptop sleeve will protect your notebook in your bag from scratches, bumps and so on. You might also want to invest in a flash or external portable drive to instantly back-up your most valuable data as you never know what might happen if you accidentally push the table your notebook is sitting on and it falls and breaks into thousands of pieces. Privacy Filter Don’t you hate when you’re sitting in a cafe, plane or any other public space and you can’t help notice the people who in all shamelessness stare at what you are doing or watching on your notebook? Enters the laptop privacy filter, which as screen that prevents people from seeing what’s going on in your laptop unless they’re sitting in front of it. That means that only you can view your computer. I actually discovered it when I glanced at a guy’s computer in a cafe and could not see anything and when I asked him about it, he explained to me what it was and how it worked. Headphones. I have said it over and over, internal laptop speakers suck. Try to listen or watch a movie in a public space and two things will happen. One, you will annoy people next to you and two, you won’t be able to hear anything as the sound quality will be so poor. Getting a good set of headphones will make the whole experience better and you will find that the added bonus of including them in your laptop accessories is the fact that by putting them on, you will isolate yourself from outside noise allowing you to better focus on your work. Wi-Fi/ Hotspot finder Normally to locate wireless Internet, you must have your computer. These cool laptop accessories allow you to figure out what networks are available to you and which ones are public! Now, in some states and countries it’s legally to access private wireless networks even if they are open but sometimes, some businesses offer wireless Internet as way to attract clients. Gone are the days when you had to drive or walk around the city with your computer on trying to find a good signal!   We supply high quality laptop accessories, like Liteon AC Adapter(Supply high quality Liteon laptop AC Adapters) DELTA AC Adapter(Supply high quality DELTA laptop AC Adapters ) Dell battery(Supply high quality Dell laptop batteries ) Acer Travelmate 2000 AC Adapter(worldwide use) Acer Aspire 1680 AC Adapter(DC19V 3.42A) Acer Aspire 1200 AC Adapter(19V 3.42A) HP NW8440 AC Adapter(18.5V 3.5A ) HP NX9000 AC Adapter(19V 4.74A) (Comment on this)

2:37 pm	There are 12 Cells in a Battery When buying a battery, we often check the capacity, like 4400mAh, 6600mAh etc. But do you know how many cells are in a battery? This is a great question for it gets to the heart of battery manufacturing and begins to unravel the power of a battery. Let’s take Toshiba Satellite M105-S3041 for example,  The answer is simply: 12 cells. But what does the answer mean and how does the number of cells relate to the overall value of a battery? Let's find out... What Type of Lithium Cell is Used in Laptops Now this brings us to battery cells and our original question from the reader. Lithium based battery cells are good but there are a variety of lithium based battery cells. For example the lithium based cell identified as 18650 is one of the most common battery cell on the market for laptops. 18650 is manufactured by many manufacturers including many private branded companies to public companies like LG, Sony, Sanyo, Samsung, and Panasonic. 18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and has a high energy density. It is in effect perfect for building batteries for laptop and other portable power devices. The additional technical specifications for the 18650 battery cell include: • Nominal Voltage Average 3.7 V - the concept of nominal voltage is that voltage range exists depending on the number of cells in the battery. • Nominal Capacity - 2200 mAh (above 2200 the stability of lithium based cells is called into question) • Max. Charging Current - 2.4 Amps Max. • Max. Discharging Current - 4.6 Amps max. • Dimensions (DxH) 18.3 mm (Max 18.4) x 64.9 mm (Max 65.1) • Weight 46.5 g (1.64 oz) • Internal Impedance Internal Impedance: less or equal to 90 ohms • Cycle Performance is 80% of initial capacity at 300 cycles Now as stated above the reader asked how many cells were in the Toshiba Satellite M105-S3041 Laptop Battery? The battery is rated at 10.8 volts and a capacity of 8800 mAh. As I mentioned above the nominal voltage average is 3.7V. Some manufacturers may use 3.6V and some may use 3.7V. In the case of a laptop battery with 10.8V the nominal voltage rating used is 3.6V. Thus if we divide 10.8V by 3.6V we get 3. Thus 3 cells in a series. We also know that the batteries capacity is 8800 mAh. We know the nominal capacity is 2200 mAh. Therefore if we divide 8800 mAh by 2200 mAh then we get 4 in parallel. How Does A Battery Create Energy? A battery is a device that converts chemical energy into electrical energy. Batteries create electrochemical energy by a chain of events that have to occur prior to the creation of electrical energy. Electricity is introduced into a battery via a charger. The charger acts as a conduit of the pushing electrons that are forcing their way into the chemical lithium. This charge process involves intercalation where electrons join with other molecules in the lithium's minuscule spaces between the the lithium's crystallized planes. Electrons are in essence ionizing lithium which loads the crystal planes to the point where they are forced into a current flow. Intercalation replenishes, in effect, lithium but the net result of ionization is the ultimate depletion of the lithium reactive property. But what makes lithium good for batteries is that lithium is a highly reactive metal. Lithium has a very high electrochemical potential. In some lithium-based cells the electrochemical potential can be five times greater than an equivalent-sized lead-acid cell and three times greater than alkaline batteries. Lithium is also pliable and bendable allowing lithium to fit in tight configurations (perfect for in small cell designs in PDAs. Laptops, Cameras etc...). Therefore the answer is very clear: 3 cells in series multiplied by 4 cells in parallel equals 12 cells in total. We can use this method to find out the number of cells of the batteries.

2:17 pm	How to Maintain Your Laptop AC Adapter? We could find lots of knowledge about how to maintain your laptop battery, but not so much about ac adapter. However, laptop AC adapter, like the batteries, is an essential element of your machine and is also the cause of a great number of breakdowns. Indeed, one of the elements most fragile of your laptop is the AC connector, i.e. the connector female in which comes to plug in the plug of your AC adapter. An adapter in bad condition (stripped cable, broken case repaired with tape...) is often the cause of a fatal electric problem to the motherboard of your laptop. To avoid that you just have to purchase a new AC adapter (genuine), it is always less expensive than a repair or a swapping of the motherboard. The repetition of these plug in and sometimes their useless violence ends regularly up tearing off the female connector of the motherboard. That often occurs by stage, initially light poor contact, then as you move the cable in all the directions to find the current, the connector is torn off definitively, or the produced sparks roast the motherboard. To try to save some dollars (whereas often the genuine adapters are not much more expensive) or simply because their retailer does not propose a genuine adapter, much buy "compatible" adapters. Let me be frank, for repairers these ac adapters are a blessing! Their male connector, relatively adapted to the socket of the laptop, tears off more often than others the females connectors. Their voltage and their amperage more or less close to the needs for your laptops and a sometimes irregular flow, even straightforwardly random, and their annoying tendency "to kill the fuses" by at the same time roasting your motherboard and other power cards, are an important source of occupation for the technicians. The failure rate, properly incredible, due, in an unquestionable or probable way, with these adapters makes that I dis-advise them formally. I am the first to propose to use compatible parts when they are less expensive and as powerful as the original parts. But for the AC adapters I advise prudence.

10:20 am	If I overcharge my laptop battery, the life span will not decrease! Lots of laptop users will meet this problem, when their batteries have been charged, they forget to pull them out. It seems that their batteries have been overcharged for a long time, there will be a doubt in their heart, if I overcharged my laptop battery, will the lif span decrease? First it’s important to understand what overcharging is: Over-charging occurs when the charger keeps the battery at a temperature that is warm to touch (body temperature) while in ready condition. Li-Ion laptop batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the battery. A lithium-based battery should never be allowed to get warm in a charger. If you have this happen, the battery is no good or the charger is not working properly. Don’t continue to use the battery or charger if this happens. A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery from overcharging would only occur in the very unlikely event of a malfunction of the charging system.

2:58 pm	Attention! Remove the laptop battery For A Desktop Replacement Laptop A user asked this question: I have a laptop at home which I use as a desktop replacement. As such, 99% of the time the laptop is being used it is plugged in. I wonder if I should remove the battery so that it is not permanently being charged, or does the laptop cut off the current to the battery once it is fully charged? I do unplug the laptop when I turn it off. The experts point out that when using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it. The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery. Remember that when you have removed the battery from a laptop while using with an electrical outlet – the automatic battery backup is no longer functional. Make sure to plug your laptop into an uninterrupted power source (UPS) not directly into an outlet or surge protector.   To check some hot-sold laptop keyboards here: Toshiba P30 keyboard Gateway MX3000 keyboard Dell Inspiron 630M keyboard Dell Inspiron 6000 keyboard HP Pavilion DV9000 keyboard See more, please click laptop accessories.

5:35 pm	Parking a PC Card on Your Laptop You have your laptop, and you have a PC Card that you want to use in your laptop. So how do the two connect? Locate on your laptop the spot where you can insert PC Cards. This spot may be an open hole on the side of the laptop, you may have a tiny "garage door" covering the hole, or you may find the hole hidden behind a removable panel. Some laptops sport a garage for two PC Cards, stacked one atop the other. Other laptops have room for only one PC Card. You insert PC Cards into the slot, "holy" end first. In fact, they fit in only one way. Push the card in all the way until it fully docks with the connectors deep down inside the laptop. To remove the card, locate the eject button along side the slot, right next to the door. Press the eject button all the way in, and the card pops out a little bit. You can then pinch the card between your thumb and forefinger, pulling it out the rest of the way. Each PC Card slot comes with its own eject button. These eject buttons appear alongside the spots where the Cards slide in. Be sure to read the instructions for your PC Card before inserting it into the slot for the first time. Some cards may require that you turn off the laptop before inserting the card. Note that some of the eject buttons pop out a ways from the laptop's case. Remember to push them back into the case when you're done with the PC Card. That way, the knob doesn't snag on anything and possibly break off.

1:51 pm	Recycling your Battery Over 75 million Nickel Cadmium (NiCd) batteries were sold in the US during the year 2000. Market predictions indicate that the demand of NiCd batteries will rise six percent per year until 2003. The demand for other chemistries such as Nickel Metal Hydride (NiMH) and Lithium Ion (Li ion) is increasing at a more rapid pace. Where will the mountains of batteries go when spent? The answer is recycling. The lead acid battery has led the way in recycling. The automotive industry should be given credit in organizing ways to dispose of old car batteries. In the USA, 98 percent of all lead acid batteries are recycled. Compared to aluminum cans (65 percent), newspaper (59 percent) and glass bottles (37 percent), lead acid batteries are reclaimed very efficiently, due in part to legislation. Only one in six households in North America recycle small rechargeable batteries. Homeowners have the lowest return ratios, but this should improve once more recycling repositories become available and better environmental awareness is emphasized. The NiCd battery is one of the more hazardous batteries in terms of disposal. If used in landfills, the cadmium will eventually dissolve itself and the toxic substance will seep into the water supply, causing serious health problems. Our oceans are already beginning to show traces of cadmium (along with aspirin, penicillin and antidepressants) but the source of the contamination is unknown. Under no circumstances can batteries be incinerated as this can cause them to explode. Although NiMH batteries are considered environmentally friendly, this chemistry is also being recycled. The main derivative is nickel, which is considered semi-toxic. NiMH also contains an electrolyte that, in large amounts, is hazardous to the environment. If no disposal service is available in an area, individual NiMH batteries can be discarded with other household wastes. If ten or more batteries are accumulated, the user should consider disposing the batteries in a secure waste landfill. Lithium (metal) batteries contain no toxic metals, however, there is the possibility of fire if metallic lithium is exposed to moisture while the cells are corroding. Most lithium batteries are non-rechargeable and are used by defense organizations. Cameras and other commercial products also use primary lithium batteries. For proper disposal, these batteries must be fully discharged in order to consume all metallic lithium content. Li ion batteries (rechargeable), on the other hand, do not contain metallic lithium and the disposal problem does not exist. Most lithium systems contain toxic and flammable electrolyte, however. In 1994, the Rechargeable Battery Recycling Corporation (RBRC) was founded to promote the recycling of rechargeable batteries in North America. RBRC is a non-profit organization that collects batteries from consumers and businesses and sends them to Inmetco and Toxco for recycling. Inmetco specializes in recycling NiCd, but also accepts NiMH and lead-based batteries. Toxco, focuses on lithium metal and Li ion system. Currently only intended to recycle NiCd batteries, RBRC will expand the program to include also NiMH, Li ion and SLA batteries. Programs to recycle spent batteries have been in place in Europe and Asia for many years. Sony and Sumitomo Metal in Japan have developed a technology to recycle cobalt and other precious metals from Li ion batteries. The rest of Asia is progressing at a slower rate. Some movements in recycling spent batteries are starting in Taiwan and China, but no significant infrastructure exists. Battery recycling plants require batteries to be sorted according to chemistries. Some sorting is done prior to the battery arriving at the recycling plants. NiCd, NiMH, Li ion and lead acid are often placed in designated boxes at the collection point. Sorting batteries must be done manually, an operation that adds to the cost of recycling. If a steady stream of sorted batteries were available at no charge, recycling would be feasible with little cost to the user. The logistics of collection, transportation and labor to sort the batteries make recycling expensive. The recycling process starts by removing the combustible material, such as plastics and insulation using a gas fired thermal oxidizer. Gases from the thermal oxidizer are sent to the plant’s scrubber where they are neutralized to remove pollutants. The process leaves the clean, naked cells, which contain valuable metal content. The cells are then chopped into small pieces, which are heated until the metal liquefies. Non-metallic substances are burned off; leaving a black slag on top that is removed with a slag arm. The different alloys settle according to their weights and are skimmed off like cream from raw milk. Cadmium is relatively light and vaporizes easily at high temperatures. In a process that appears like a pan boiling over, a fan blows the cadmium vapor into a large tube, which is cooled with water mist. This causes the vapors to condense. A 99.95 percent purity level of cadmium can be achieved using this method. Some recyclers do not separate the metals on site but pour the liquid metals directly into what the industry refers to as ‘pigs’ (65 pounds) or ‘hogs’ (2000 pounds). The pigs and hogs are then shipped to metal recovery plants. Here, the material is used to produce nickel, chromium and iron re-melt alloy for the manufacturing of stainless steel and other high end products. Current battery recycling methods requires a high amount of energy. It takes six to ten times the amount of energy to reclaim metals from recycled batteries than it would through other means. A new process is being explored, which may be more energy and cost effective. One method is dissolving the batteries with a reagent solution. The spent reagent is recycled without forming any atmospheric, liquid or solid wastes. Who pays for the recycling of batteries in bulk? Participating countries impose their own rules in making recycling feasible. In North America, some recycling plants bill on weight. The rates vary according to chemistry. Systems that yield high metal retrieval rates are priced lower than those that produce less valuable metals. The highest recycling fees apply to NiCd and Li ion batteries because the demand for cadmium is low and Li ion batteries contain little retrievable metal. The recycling cost of alkaline is 33 percent lower than that of NiCd and Li ion because the alkaline cell contains iron. The NiMH battery yields the best return. Recycling NiMH produces enough nickel to pay for the process. Not all countries base the cost of recycling on the battery chemistry; some put it on tonnage alone. The average cost of recycling batteries is $1,000 to $2,000US per ton. Europe hopes to achieve a cost per ton of $300US. Ideally, this would include transportation, however, moving the goods is expected to double the overall cost. For this reason, Europe is setting up several smaller processing locations in strategic geographic locations. laptop battery Significant subsidies are sill required from manufacturers, agencies and governments to support the battery recycling programs. These subsidies are in the form of a tax added to each manufactured cell. RBRC is financed by such a scheme.

10:54 am	Laptop Keyboard Repair Laptops have become an integral part of our lives. However, the sad fact remains that all the laptops available in the market are not standardized. Each manufacturer has different sizes of laptops to offer and sometimes the size of the parts differ. This fact is not a problem, at least not until the laptop starts needing repairs or replacement parts. Since one laptop is quite different from the other, it is very difficult to repair them in the first place, or in case of a replacement, find a part for the specific type of laptop. Even a simple thing like a laptop keyboard, is different for different makes and models of laptops on the market. The main problem that arises due to rigorous usage of laptop keyboards is of damaged keys. Sometimes, the port that connects the keyboard to the laptop inside also gets damaged. If the damage is of the connecting cable inside the laptop, there is not much repair work required. Repair is surely possible if there is a problem with some of the keys. Every key in any keyboard has a spring like arrangement that allows the key to press the sensor below and show the typed words on the screen. Most of the problems with keyboards and their keys occur when it refuses to press the sensor below and the typed alphabet will not show on the screen. This can be rectified easily and does not need the help of a repair person. One can find an online guide and find out how to take the key out of its main body. Once you do that, you can see for your self what's wrong with the keyboard. If you find that it is damaged below, you can try and fix it on your own or if you are unable to do so, you can go in for a new key to put in its place. This is where the problem starts. It is not easy to find as small a spare part as a few damaged keys. However, the possibility of finding them increases in a used laptop store. Laptops that are damaged that they cannot be repaired are disassembled and their parts sold separately in the market. You are sure to find your keys there. If a keyboard is damaged beyond repair then one has to go in for the replacement of the keyboard which proves to be quite expensive. Another option is to use a new external keyboard with a USB or PS2 port and can use that keyboard for laptop computers.

3:34 pm	What's the best battery? Battery novices often brag about miracle batteries that offer very high energy densities, deliver 1000 charge/discharge cycles and are paper-thin. These attributes are indeed achievable but not on one and the same battery pack. A certain battery may be designed for small size and long runtime but has a limited cycle life. Another pack may be built for durability and is big and bulky. A third may have high energy density and long durability but is made for a special application and is too expensive for the average consumer. A lithium-based battery can be designed for maximum energy density but its safety would be compromised. Battery manufacturers are aware of customer needs and offer packs that best suit the application. The mobile phone industry is a good example of this clever adaptation. Here, small size and high energy density reign in favor of longevity. Short service life is not an issue because a device is often replaced before the battery is worn out. Below is a summary of the strength and limitations of today's popular battery systems. Although energy density is paramount, other important attributes are service life, load characteristics, maintenance requirements, self-discharge costs and safety. Nickel-cadmium is the first rechargeable battery in small format and forms a standard against which other chemistries are commonly compared. The trend is towards lithium-based systems. Nickel-cadmium - mature but has moderate energy density. Nickel-cadmium is used where long life, high discharge rate and extended temperature range is important. Main applications are two-way radios, biomedical equipment and power tools. Nickel-cadmium contains toxic metals. Nickel-metal-hydride - has a higher energy density compared to nickel-cadmium at the expense of reduced cycle life. There are no toxic metals. Applications include mobile phones and laptop computers. NiMH is viewed as steppingstone to lithium-based systems. Lead-acid - most economical for larger power applications where weight is of little concern. Lead-acid is the preferred choice for hospital equipment, wheelchairs, emergency lighting and UPS systems. Lead acid is inexpensive and rugged. It serves a unique niche that would be hard to replace with other systems. Lithium-ion - fastest growing battery system; offers high-energy density and low weight. Protection circuit are needed to limit voltage and current for safety reasons. Applications include notebook computers and cell phones. High current versions are available for power tools and medical devices. Table 1 summarizes the characteristics of the common batteries. The figures are based on average ratings at time of publication. Lithium-ion is divided into three versions: The traditional cobalt that is commonly used in cell phones, cameras and laptops; the manganese (spinel) that power high-end power tools and the new phosphate that competes head-on with spinel. Lithium-ion polymer is not listed as a separate system. Its unique construction performs in a same way to cobalt-based lithium-ion. Table 1: Characteristics of commonly used rechargeable batteries. 1) Internal resistance of a battery pack varies with mAh rating, wiring and number of cells. Protection circuit of lithium-ion adds about 100mW. 2) Based on 18650 cell size. Cell size and design determines internal resistance. Larger cells can have an impedance of <15mOhms, 3) Cycle life is based on battery receiving regular maintenance. Failing to apply periodic full discharge cycles may reduce the cycle life by a factor of three. 4) Cycle life is based on the depth of discharge. Shallow discharges provide more cycles than deep discharges. 5) The self-discharge is highest immediately after charge, and then tapers off. The capacity loss of nickel-cadmium is 10% in the first 24h, then declines to about 10% every 30 days thereafter. High temperature increases self-discharge. 6) Internal protection circuits typically consume 3% of the stored energy per month. 7) The traditional nominal voltage is 1.25V; 1.2V is more commonly used to harmonize with lithium-ion (3 in series = 3.6V). 8) Lithium-ion is often rated higher than the nominal 3.6V. Based on average voltage under load. 9) Capable of high current pulses; needs time to recuperate. 10) Applies to discharge only; charge temperature range is more confined. Delivers lower capacity at lower temperatures. 11) Maintenance may be in the form of 'equalizing' or 'topping' charge to prevent sulphation. In subsequent columns I will describe the strength and limitation of each chemistry in more detail. We will examine charging techniques and explore methods to get the most of these batteries.

5:24 pm	The nickel-based battery, its dominance and the future In this section we evaluate the strengths and limitations of various battery chemistries, beginning with the nickel. Each battery system offers unique advantages but none provides a fully satisfactory solution. With the increased selection of battery chemistries available today, better choices can be made to address specific battery needs. A careful evaluation of each battery's attribute is important. Because of similarities, both nickel-cadmium and nickel-metal hydride are covered in this paper. The nickel-cadmium battery Swedish Waldmar Jungner invented the nickel-cadmium battery in 1899. At that time, the materials were expensive compared to other battery types available and its use was limited to special applications. In 1932, the active materials were deposited inside a porous nickel-plated electrode and in 1947 research began on a sealed nickel-cadmium battery. Rather than venting, the internal gases generated during charge were recombined. These advances led to the modern sealed nickel-cadmium battery, which is in use today. Nickel-cadmium prefers fast charge to slow charge and pulse charge to DC charge. It is a strong and silent worker; hard labor poses little problem. In fact, nickel-cadmium is the only battery type that performs well under rigorous working conditions. All other chemistries prefer a shallow discharge and moderate load currents. Nickel-cadmium does not like to be pampered by sitting in chargers for days and being used only occasionally for brief periods. A periodic full discharge is so important that, if omitted, large crystals will form on the cell plates (also referred to as memory) and the nickel-cadmium will gradually lose its performance. Among rechargeable batteries, nickel-cadmium remains a popular choice for two-way radios, emergency medical equipment and power tools. There is shift towards batteries with higher energy densities and less toxic metals but alternative chemistries cannot always match the superior durability and low cost of nickel-cadmium. Here is a summary of the advantages and limitations of nickel-cadmium batteries. Advantages Fast and simple charge, even after prolonged storage. High number of charge/discharge cycles - if properly maintained, nickel-cadmium provides over 1000 charge/discharge cycles. Good load performance - nickel-cadmium allows recharging at low temperatures. Long shelf life - five-year storage is possible. Some priming prior to use will be required. Simple storage and transportation - most airfreight companies accept nickel-cadmium without special conditions. Good low temperature performance. Forgiving if abused - nickel-cadmium is one of the most rugged rechargeable batteries. Economically priced - nickel-cadmium is lowest in terms of cost per cycle. Available in a wide range of sizes and performance options - most nickel-cadmium cells are cylindrical. Limitations Relatively low energy density. Memory effect - nickel-cadmium must periodically be exercised (discharge/charge) to prevent memory. Environmentally unfriendly - nickel-cadmium contains toxic metals. Some countries restrict its use. Relatively high self-discharge - needs recharging after storage The nickel-metal-hydride battery Research on the nickel-metal-hydride system started in the 1970s as a means of storing hydrogen for the nickel hydrogen battery. Today, nickel hydrogen is used mainly for satellite applications. nickel hydrogen batteries are bulky, require high-pressure steel canisters and cost thousands of dollars per cell. In the early experimental days of nickel-metal hydride, the metal hydride alloys were unstable in the cell environment and the desired performance characteristics could not be achieved. As a result, the development of nickel-metal hydride slowed down. New hydride alloys were developed in the 1980s that were stable enough for use in a cell. Since then, nickel-metal hydride has steadily improved. The success of nickel-metal hydride has been driven by high energy density and the use of environmentally friendly metals. The modern nickel-metal hydride offers up to 40% higher energy density compared to the standard nickel-cadmium. There is potential for yet higher capacities, but not without some negative side effects. Nickel-metal hydride is less durable than nickel-cadmium. Cycling under heavy load and storage at high temperature reduces the service life. nickel-metal hydride suffers from high self-discharge, which is higher than that of nickel-cadmium. Nickel-metal hydride has been replacing nickel-cadmium in markets such as wireless communications and mobile computing. Experts agree that nickel-metal hydride has greatly improved over the years, but limitations remain. Most shortcomings are native to the nickel-based technology and are shared with nickel-cadmium. It is widely accepted that nickel-metal hydride is an interim step to lithium-based battery technology. Here is a summary of the advantages and limitations of nickel-metal hydride batteries. Advantages 30-40% higher capacity than standard nickel-cadmium. Nickel-metal-hydride has potential for yet higher energy densities. Less prone to memory than nickel-cadmium - fewer exercise cycles are required. Simple storage and transportation - transport is not subject to regulatory control. Environmentally friendly - contains only mild toxins; profitable for recycling. Limitations Limited service life - the performance starts to deteriorate after 200-300 cycles if repeatedly deeply cycled. Relatively short storage of three years. Cool temperature and a partial charge slows aging. Limited discharge current - although nickel-metal-hydride is capable of delivering high discharge currents, heavy load reduces the battery's cycle life. More complex charge algorithm needed - nickel-metal-hydride generates more heat during charge and requires slightly longer charge times than nickel-cadmium. Trickle charge settings are critical because the battery cannot absorb overcharge. High self-discharge - typically 50% higher than nickel-cadmium. Performance degrades if stored at elevated temperatures - nickel-metal-hydride should be stored in a cool place at 40% state-of-charge. High maintenance - nickel-metal hydride requires regular full discharge to prevent crystalline formation. nickel-cadmium should be exercised once a month, nickel-metal-hydride once in every 3 months.
