One of the most common problems with laptops is running out of battery power before you're finished using your computer. Battery Status in Windows Mobility Center shows you how much charge is left in your battery and offers a quick way to change power plans so that your battery lasts longer.
Using the right power plan, adjusting the screen brightness, and unplugging computer peripherals that you're not using help make your battery last longer between charges.
- Power plans. Windows includes three power plans—Power saver, High performance, and Balanced—to conserve battery power, make your computer perform better, or strike a balance between the two. Unless you change the power plan, your laptop uses the Balanced power plan to automatically balance system performance and battery life. To make your battery last longer, choose the Power saver plan.
- Screen brightness. The brighter your screen, the more battery power your computer uses. Power plans will automatically adjust the screen brightness, but to maximize battery life, you can make the screen dimmer by changing the brightness setting in Mobility Center.
- Unused peripherals. An external mouse, music player, or other USB device uses your computer's power when it's plugged in. Unplug these devices if you're not using them, and try using a built-in pointing device, such as a touch pad or tablet pen, to conserve battery power.
