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.
