When a battery that is the sole power source for the computer reaches a low or critical battery level, the following behavior occurs:

●The battery light (select models only) indicates a low or critical battery level.

– or –

●The Power Meter icon on the Desktop shows a low or critical battery notification.

NOTE: For additional information about the power meter, see Using the power meter and power settings on page 34.

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.

Resolving a low battery level

Resolving a low battery level when external power is available

●Connect an AC adapter.

●Connect an optional docking or expansion device.

●Connect an optional power adapter purchased as an accessory from HP.

Resolving a low battery level when no power source is available

●Initiate Hibernation.

●Save your work and shut down the computer.

Resolving a low battery level when the computer cannot exit Hibernation

When the computer lacks sufficient power to exit Hibernation, follow these steps:

1.Replace the discharged user-replaceable battery with a charged battery, or connect the AC adapter to the computer and to external power.

2.Exit Hibernation by pressing the power button.

Storing a user-replaceable battery

CAUTION: To reduce the risk of damage to a battery, do not expose it to high temperatures for extended periods of time.

If a computer will be unused and unplugged from external power for more than 2 weeks, remove the battery and store it separately in a cool, dry place to prolong the battery charge.
