Battery
The battery that comes with your computer provides power to the real-time clock and has a lifetime of
about three years. When replacing the battery, use a battery equivalent to the battery originally installed
on the computer. The computer comes with a 3-volt lithium coin cell battery.
NOTE:
The lifetime of the lithium battery can be extended by plugging the computer into a live AC wall
socket. The lithium battery is only used when the computer is NOT connected to AC power.
WARNING!
This computer contains an internal lithium manganese dioxide battery. There is a risk of
fire and burns if the battery is not handled properly. To reduce the risk of personal injury:
❑
Do not attempt to recharge the battery.
❑
Do not expose to temperatures higher than 60°C (140°F)
❑
Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
❑
Replace the battery only with the HP/Compaq spare designated for this product.
CAUTION:
Before replacing the battery, it is important to back up the computer CMOS settings. When
the battery is removed or replaced, the CMOS settings will be cleared. Refer to the
Troubleshooting
Guide
for information on backing up the CMOS settings.
NOTE:
Batteries, battery packs, and accumulators should not be disposed of together with the general
household waste. In order to forward them to recycling or proper disposal, please use the public
