Laptop Battery won't Hold Charge - Introduction, Replacement and Fixing

May 24, 2022 Pageview:28

A laptop battery that won't hold charge is one of the most annoying problems you can encounter—you'll want to replace the battery or at least fix it. A battery that won't charge past a certain percentage or that loses its charge quickly will usually be the problem of a defective cell.

To figure out which cells are defective and need to be replaced, we need to test each one individually by connecting them to a power supply and measuring their voltage drops with a high-resistance voltmeter. Get an old power supply if you don't want to buy a new one just for this purpose—a battery charger should still be able to provide enough power for our testing.

The most common cause of a laptop's battery not holding a charge is due to the passage of time, where the battery loses its capacity to hold charges. Unfortunately, this is something that can't be fixed. The only thing you can do is find a replacement or get a new battery. Since batteries are made to last around 5 years, you may have gotten one that just reached its end-of-life.

Another problem with batteries is when it gets too hot. If the battery becomes too hot, it can start leaking and damaging your laptop. The best way to solve this problem is to prevent it from happening in the first place by making sure your laptop stays cool when you are using it. Place it on a table instead of on your lap or in your bed. If you're using it for an extended period of time, make sure you use an AC adaptor so that the battery doesn't have to work as hard and heat up as much. Also make sure to keep fan vents clear, especially if you live in an area that has a lot of dust or animals.

One more thing that can damage your battery is leaving it in extreme temperatures for long periods of time. Do not leave your laptop in a car or another enclosed area during cold or hot seasons.

When you buy a new battery, it's best to get it from someone reputable so you can feel confident in its quality. A reputable replacement should work just as well as the original and will have the same specifications. If your laptop has been exposed to water or other liquids, we recommend getting a new battery because there's no telling whether previous repairs were done properly or if there's residual damage that wouldn't show up until later on.

When you buy a new laptop battery, you might be surprised to find that your old one works just fine. That can be because the issue wasn't the battery at all, but some other parts of your computer. Before you spend a lot of money on new hardware, make sure you're not missing something simple that could be the problem.

New Laptop Battery won't Hold Charge

If you're dealing with a brand new laptop that won't hold a charge, there are a few things you should look into before giving up on it altogether. The first thing to do is check your power settings. If they're set to never sleep or hibernate, the computer will constantly be running on the battery, draining it completely.

You could also check that all of your software is up to date. If there's an update available, it might be causing your battery problems. If you don't use any of your programs as often then make sure they're not running in the background. If you are using your computer often, try closing out of some programs and then turning off your screen for a period of time. This may allow your battery to recharge some more.

Finally, if none of these ideas work for you, you may have a bad charger or the motherboard might not be working properly. Check online for customer reviews about the charger you have and make sure it's compatible with your model laptop. You can also try replacing the charger yourself or taking it to a repair shop if you feel comfortable with doing so.

Laptop Battery Replacement

From the very first time you turn on your laptop to when you put it to sleep, the battery is constantly recharging and discharging. Over time, this cycle causes the battery to lose capacity—to hold less energy than it used to. If you don't replace your laptop's battery, you'll eventually find that it needs to be plugged in all the time.

Here is how to replace the battery in your laptop to save money and extend its life.

Make sure that your laptop is turned off and unplugged from all power sources before starting. You will want to remove any screws from the bottom of your laptop.

Remove the battery from your laptop by finding where on the body it is located and then popping it out by hand or with a screwdriver. The old battery will be either glued or soldered into place; if it is glued in, you can use a razor blade to cut through the glue easily.

The next step is to take apart the new battery if necessary. Most batteries have tabs that need to be popped off before they can be removed; you should be able to do this with your hands, but it may be necessary to use pliers as well if there are multiple tabs on one side.

Once you've finished taking apart the new battery, you can put it back together again and place it in your laptop. Make sure that there are no wires or other pieces laying loose inside your computer, as this could cause a short-circuit that could damage your machine and possibly even cause a fire! There may also be screws holding the old battery in place; if so, make sure that these are tight before you close up your computer and power it on.

Once you put everything back together again and plug in your laptop, your new battery should work exactly like the old one did.

How to Fix a Laptop Battery that won't Hold a Charge?

If your laptop's battery won't hold a charge, it can be hard to know where to start. Here are some simple steps you can take to diagnose and fix the problem.

The first step is to check if your laptop is charging at all by plugging in the power adapter and seeing if the charge indicator on your computer lights up.

Next, you should make sure that nothing has come loose in the port where the power adapter goes in.

If the connection looks solid, try out different power adapters and outlets. It's possible that the charger isn't working properly or that there is something wrong with the outlet you were using. Finally, if you're still having trouble, find out if your warranty covers battery replacement and contact your manufacturer for further information.
