Make Your Battery Last Longer
No matter what type of laptop you buy, you’re going to want it to last for several hours or more when it’s running on battery power. 
If it doesn’t, you may find that you can’t use your laptop on the go or that you lose information if you don’t keep an eye on the battery level. However, there are some things you can do to increase your laptop’s battery life. Here are a few of them.
• Turn down your screen’s brightness. Most newer laptops automatically dim the screen when on battery power.
• Turn off your Wi-Fi and/or Bluetooth connections if you aren’t using the internet.
• Look at your laptop’s power options to be sure they’re set appropriately. For example, you may want to set your laptop to turn off the hard drive and screen after several minutes of inactivity. Put your laptop in stand-by mode if you won’t be using it for an hour or so, but have it hibernate if you will be away from it for a longer period of time.
• Disconnect USB devices and other external hardware. Using your laptop’s touchpad instead of using a USB mouse will also save power.
• Turn down or mute your speakers.
• Install programs to your hard drive instead of running them off of CD/DVD.
• Shut down scheduled tasks such as virus scans. You can also save on power by turning off Auto-save.
