Conserving battery power

●Select Start > Control Panel > System and Security > Power Options > Power saver.

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

●Disconnect external devices that are not plugged into an external power source, when you are not using them.

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

●Use the fn+f7 and fn+f8 hotkeys to adjust screen brightness as needed.

●If you leave your work, initiate Sleep or Hibernation, or shut down the computer.

Storing a battery

CAUTION: To prevent 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.

For additional information, refer to the Regulatory, Safety and Environmental Notices included with this computer.

Replacing the battery

Computer battery life varies, depending on power management settings, programs running on the computer, display brightness, external devices connected to the computer, and other factors.

Battery Check notifies you to replace the battery when an internal cell is not charging properly, or when the battery storage capacity has reached a ”weak” condition. A message refers you to the HP Web site for more information about ordering a replacement battery. If the battery is possibly covered by an HP warranty, instructions include a warranty ID.

NOTE: To ensure that you always have battery power when you need it, HP recommends purchasing a new battery when the storage capacity indicator turns green-yellow.
