Battery Replacement

The battery that comes with your computer provides power to the real-time clock and has a minimum lifetime of about three years. When replacing the battery, use a battery equivalent to the battery originally installed on your computer. Your computer comes with a 3-volt lithium coin cell battery.

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: Your 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 (140ºF).

■Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.

■Replace the battery only with the 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.

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 collection system or return them to Compaq, their authorized partners, or their agents.
