From the Start screen, you can also type power options, and then select Power Options. Different power meter icons indicate whether the computer is running on battery or external power.

Running on battery power When a charged battery is in the computer and the computer is not plugged into external power, the computer runs on battery power. If the computer has a charged battery installed and the AC adapter is disconnected from the computer, the computer automatically switches to battery power and the screen brightness decreases to conserve battery life. The battery in the computer slowly discharges when the computer is off and unplugged from external power. Computer battery life varies, depending on power management settings, programs running on the computer, screen brightness, external devices connected to the computer, and other factors.

CAUTION: Removing a user-replaceable battery that is the sole power source for the computer can cause loss of information. To prevent loss of information, save your work or shut down the computer through Windows before removing the battery. 1. Turn the computer upside down on a flat surface. 2. Slide the battery lock (1) to unlock the battery, and then slide the battery release latch (2) to release the battery.
