Laptop batteries vary greatly in their life and effectiveness. Some can last up to six hours while others might not even last one hour after a full charge. This depends greatly on the type of laptop, its brand, how it is being used, etc. The best thing you can do if you are trying to conserve battery life is turn down the brightness on your display screen as much as possible since this uses the most power by far.
Also try using “Power Options” in Windows XP or Vista. That will allow you to change settings so that when you are plugged in, your power plan is set to “Max Battery”. If you are running off of the battery then it automatically switches over to “High Performance”. One thing to consider when you are using the battery though is that your computer might not be able to handle the power required for “High Performance” which will drain the battery.
Also, if you want to conserve on your laptop’s battery life, don’t use an optical mouse. Optical mice use more energy than track pads or ball mice because they need a light source in order to function properly.
If you are planning on taking your laptop outside of your home, don’t forget to take your adapter with you! Even if it does still have some charge left in it, try and plug it up before it gets down too low so that you can ensure that you get maximum usage out of it.
You should also consider buying a new battery if your old one is not lasting nearly as long as you would like it to. There are many types of batteries out there so it is important that you are getting the correct type for your laptop. Also, keep in mind that sometimes just because a battery says that it is compatible with your computer does not mean that it actually will be!
If trying all of these tips still does not give you enough life out of your laptop’s battery then one final thing you should consider doing (which might seem obvious) is turning the darn thing off when you aren’t using it! A lot of people probably forget this since we live in an “on-the-go” world and think nothing about leaving their laptop on in their bag. However, if you want to ensure that you get the most out of your battery then leaving it on is certainly not going to help.
One final thing that is important to consider when it comes to a laptop’s battery usage is how old the battery actually is. Just like with any device, a laptop’s battery starts losing its efficiency after a period of time and usually this happens at around three years or so. So if you’ve had your computer for over 3 years and still haven’t seen much improvement in your battery life, then you know what might be wrong!
In general though, there are many different things which can affect how long your laptop will last on charge, but hopefully these tips will help you to conserve some of that precious energy.
