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 battery with a charged battery, or connect the AC adapter to the
computer and to external power.

2.

Exit Hibernation by briefly pressing the power button.

Conserving battery power

Turn off wireless and local area network (LAN) connections and exit modem applications when
you are not using them.

Disconnect unused external devices that are not plugged into an external power source.

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

Decrease brightness.

Initiate Suspend or Hibernation, or shut down when you are not using the computer.

Storing a 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.

To prolong the charge of a stored battery, place it in a cool, dry place.

NOTE:

A stored battery should be checked every 6 months. If the capacity is less than 50 percent,

recharge the battery before returning it to storage.

Calibrate a battery before using it if it has been stored for one month or more.

Disposing of a used battery

WARNING!

To reduce the risk of fire or burns, do not disassemble, crush, or puncture; do not short

external contacts; do not dispose of in fire or water.

See the Regulatory, Safety and Environmental Notices for battery disposal information.
