Managing low battery levels

The information in this section describes the alerts and system responses set at the factory. Some low-battery alerts and system responses can be changed using Power Options in Windows Control Panel. Preferences set using Power Options do not affect lights.

Identifying low battery levels

If a low battery level is not resolved, the computer enters a critical battery level.

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

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

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

Resolving a low battery level

CAUTION: To reduce the risk of losing information when the computer reaches a critical battery level and has initiated Hibernation, do not restore power until the power lights turn off.

Resolving a low battery level when external power is available

To resolve a low battery level when external power is available, connect on of the following devices:

●AC adapter

●Optional expansion product or docking device

●Optional power adapter

Resolving a low battery level when a charged battery is available

To resolve a low battery level when a charged battery is available:

1.Shut down the computer or initiate Hibernation.

2.Remove the discharged battery, and then insert a charged battery.

3.Turn on the computer.

Resolving a low battery level when no power source is available

To resolve a low battery level when no power source is available, initiate Hibernation or save your work and then shut down the computer.

Resolving a low battery level when the computer cannot exit Hibernation
