Conserving battery power

Tips for conserving battery power and maximizing battery life:

Lower the brightness on the display.

Select the Power saver setting in Power Options.

Remove the user-replaceable battery from the computer when it is not being used or charged.

Turn off wireless devices when you are not using them.

Disconnect unused external devices that are not plugged into an external power source, such as an external hard drive connected to a USB port.

Stop, disable, or remove any external media cards that you are not using.

Before you leave your work, initiate Sleep or shut down the computer.

Identifying low battery levels

When a battery that is the sole power source for the computer reaches a low or critical battery level, the power meter icon on the Windows desktop shows a low or critical battery notification.

NOTE: For additional information about the power meter, refer to Using the power meter and power settings on page 37.

The computer takes the following actions for a critical battery level:

If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains briefly in the Sleep state, and then shuts down and loses any unsaved information.

If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates Hibernation.
