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.

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.

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.
