Most Common Laptop Battery Problems

Laptop Expert — Fri, 18 Sep 2009 10:16:51 +0000

What would we do without laptops? From those who prefer to do work on the go at a coffee shop to those who simply want a smaller computer to work on from home, laptop computers are the way to go. They are portable, easy to work on and the answer to many who wish for a fast method of jumping onto the Internet or performing work no matter where they are. However, as most laptop users know, it is not always possible to plug your laptop in, and you must be able to depend on your machine’s batteries. Batteries can be very expensive, so let’s take a look at the most common laptop battery problems that users experience and some tips that may help laptop users.

Laptop Battery Problems

It has probably happened to you before; you were working on an important presentation or perhaps a complicated Excel spreadsheet when your laptop suddenly warned you that the battery was low. You rush to save your work before everything closes down. Or perhaps you just charged your laptop, believed all would be fine and suddenly an issue occurred. It’s happened to all of us, so let’s take look at the most common laptop battery problems that people experience and what may be done to prevent them.

Batteries, as you probably know, can be extremely expensive. The main reason for this is that the manufacturer of any particular laptop is the only manufacturer for the battery as well. Each laptop will only work with one certain battery and most are not interchangeable as everyday batteries are.

Because of this, owners are not given the opportunity to shop around and compare prices. Many times, the battery itself is almost as expensive as the laptop. For this reason, we are discussing the most common laptop battery problems.

One of the most common problems is called memory effect. This is a term used to describe what happens when an owner constantly recharges the battery without it discharging fully. For example, you may have worked on your laptop all day and noticed in the evening that the battery had roughly half life left. You then charge the battery overnight and wake up to a fully charged one. This may seem like a good idea, however charging a battery that is not fully discharged and in need of charging will eventually cause memory effect and begin to last less and less time for you until eventually a so-called fully charged battery only lasts minutes. While batteries are not alive, this is referred to as the battery forgetting that it has unused capacity and it discharges faster each time that it is used. This can all be avoided if you only recharge your laptop battery when it truly needs charging.

Another one of the most common laptop battery problems is when a laptop is left sitting unused, with the battery still in it. Even while not in use, the battery will slowly be drained. You will then find that when you do finally try to turn on your laptop, the battery is dead . This can be avoided by taking out the battery if you will not be using your laptop for several days to a week or longer.

Another issue that is one of the most common laptop battery problems is an overheating battery. Have you ever been at work on your machine and realized that the battery was becoming very hot to the touch? If this happens, the battery would be removed and allowed to cool off. If this issue continues to happen, it may be a defective battery. It is then recommend to not use that battery as doing so could cause damage to your machine.

You can also experience battery problems if you allow your battery to completely discharge outside the laptop. You should check the battery while it in storage so it will not be allowed to completely discharge. This could also prevent the laptop from accepting the battery when you place it back into the computer.

If your laptop battery becomes hot to the touch you will need to remove the battery and allow it to cool off. If this problem continues when you replace the battery in the laptop, you will probably have a defective battery. It is best to remove the battery and replace it since a defective battery could cause extensive damage to the laptop. Check with the manufactured to see if your particular battery has been recalled.

Amazing History Of Laptop Batteries

Whenever you power up your laptop you may not think about the history that has gone on to help us get to where we are today. Our laptops have come a long way to become as powerful as they are, but what we do not think about is how far the laptop batteries have come. The history of laptop batteries is an amazing one. They have come along way, and in the end they still have a long way to go before they are perfect. However, we can be happy that we have learned from our mistakes and come up with a battery that is lighter and longer lasting than older ones.

Solar Battery Charger

The laptop is a great thing. It allows you to use your computer without having to be plugged up to a wall. However, back in the day you could not run your laptop off the batteries alone for too long. Thanks to people always looking to improve what we already have, we have made great jumps in the history of the batteries. When we think of laptop batteries many of us think about the rechargeable ones that we use today. However, did you know that they used to make laptops that ran off AA batteries? Not only did it take a lot of AA batteries to run a laptop, but they could not run it for long. Many people today remember the laptops running off the very heavy lead acid based batteries. Not only did these batteries not last long, but it made your laptop very heavy. You might as well been carrying around a desktop. Since then the history of laptop batteries have kept improving. In fact, after we turned in the old lead acid batteries we moved on to the nickel cadmium batteries.

If you do not remember ever hearing of nickel cadmium batteries, that is because some people called them NiCD. However, these batteries were not around too long because we soon left those for nickel metal hydribe batteries (also called NiMH). As you can guess both of these batteries lasted a lot longer than the old acid ones, however, we were not done making great batteries just yet. After that we moved on to the lithium ion batteries as well as the lithium polymer. These are the batteries that most laptops use today. However, we are not done making great batteries, and you can bet that the history of laptop batteries is going to move on from here. As more and more people get laptops every year the demand for a longer lasting batter is ever growing. Until we can make a battery that never dies, we are always going to see more improvements in the life of batteries.

People use there laptops for many different things. Some use it for school, and others use it for work. However, no matter what you use your laptop for, you know that you need a long last battery. You have to know that you are going to be able to count on the battery when you need your laptop the most. Because of that, we should be happy that batteries keep improving. The history of laptop batteries is a long one, and it’s going to just keep getting longer. All that means is that we are going to end up with some great batteries over the course of a few years. As companies jump at the chance to improve their laptops you are going to see some of the worlds best batteries come to be. What that means for us is the fact that we can have great running computers that do not die after a few hours.

Energy Efficiency Without Batteries

It is interesting if anyone could believe that soon it will possible to power laptops without any wire, just through the air. Of course nowadays we can expect any wonder in the world of technology, as we can see its evolution in full size.

CES 2009 Logo

The International Consumer Electronics Show taking place in Las Vegas last week showed brilliantly that it is quite possible at first for such commercial products as digital picture frames, audio speakers and untethered lighting.

Specialists think what WiFi does for the internet, WiTricity, wireless electricity, will be able to do for laptops, to be more exactly for laptop batteries. This electricity broadcasting will be possible for different gadgets.

CES 2009

The editor of gadgets website Electricpig.co.uk. Mr. James Holland says on this point:

“You’d be able to buy a desk that charged any gadget placed on it, or power any PC you put on top, if each room had wireless power, you’d know that once you walked through the front door your mobile would start charging up – even while still in your bag or pocket. You’d never need to hunt for the right charger again.”

The system of PowerBeam, showing the new technology, provides power to an invisible laser, the beamed electricity then comes as heat to a solar cell, converting it back to electric power.

The co-founder of the company Mr. Graham says:

“We’re going to delete the word ‘recharge’ from the English dictionary. If your cellphone is recharging on your desk all day, you won’t be thinking about it.”

It is hard to imagine, but is likely true, the world with no batteries and no charges is coming.

HP and Dell Laptop Battery Shortages

Laptop Expert — Thu, 03 Apr 2008 21:36:23 +0000

With the battery being such an integral component of a notebook computer, the cost of the laptop battery can have a noticeable effect on the cost of the entire notebook.

Reuters reports that Dell announced this week that there was a shortage of laptop batteries because in part of a fire at a major laptop battery manufacturer – LG Chem.

Dell also admitted that prices for laptop batteries sold separately from a notebook system have gone up because of the shortage. LG Chem, one of the leading makers of batteries for laptops, had a fire in its Ochang plant on March 3. Dell says that it is working with other vendors to obtain batteries in an attempt to stave the shortage and prevent price increases for new notebooks from being passed on to consumers.

Dell spokesman Jess Blackburn told Reuters,

“We sell battery packs. The prices of those battery packs for people ordering extra batteries have gone up.”

However, Blackburn didn’t comment on the amount of the price increase.

Dell isn’t the only PC maker looking at laptop battery shortages; Hewlett Packard is feeling the same pinch. Hewlett-Packard spokesperson Mike Hockey said,

“The full extent of the impact to Hewlett Packard and other OEMs is still being determined. We are aggressively working within the battery cell industry to secure additional supply of battery cells.”

LG to Replace Laptop Batteries

Laptop Expert — Wed, 27 Feb 2008 23:37:42 +0000

LG Electronics has offered free replacement batteries after two users claimed that their notebook PCs exploded. Despite the recall offer, LG has so far described the incidents as “isolated “. The partial recall applies to batteries manufactured by LG Chemical for two recent laptop models, the LG Z1 and LG Z2.

Video shot in January showed a journalist’s LG Z1-AE007 notebook burning and then exploding.

LG stopped selling the Z1 last week after a second battery fire was reported, according to South Korea’s Yonhap News Agency. The first battery fire was triggered by “unusual heat and pressure”, a researcher from the Korea Electrotechnology Research Institute told the Korea Times. However, the researchers were unable to discover how that battery had got into such a state. The notebook’s owner claimed that it had been put into a backpack in sleep mode a short while before catching fire, and that there was nothing unusual about the storage conditions.

Common safety standards call for Lithium-based batteries to withstand at least 10 minutes at 130 degrees centigrade.
