Disposing of a used battery
WARNING! To reduce the risk of fire or burns, do not disassemble, crush, or puncture a battery;
short the external contacts on a battery; or dispose of a battery in fire or water. Do not expose a
battery to temperatures above 60˚C (140˚F). Replace the battery only with a battery approved for this
computer.
Refer to the Regulatory, Safety and Environmental Notices for battery disposal information.
Replacing the battery
Computer battery life varies, depending on the 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.
