Battery Replacement

Replacing the Battery

The battery that comes with your computer provides power to the real-time clock and has a lifetime of about three to five years. When replacing the battery, use an equivalent 3-volt lithium coin cell battery. A replacement battery may be purchased at your local retailer or from the Compaq.com Web site.

The spare part number for a standard coin cell battery is 153099-001, which corresponds to a CR2032 battery or equivalent.

WARNING: Your computer contains an internal lithium manganese dioxide, vanadium pentoxide, or alkaline battery or battery pack. There is a risk of fire and burns if the battery pack is not handled properly. To reduce the risk of personal injury:

Do not attempt to recharge the battery.

Do not expose the battery to temperatures higher than 140°F (60°C).

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

Replace the battery only with the Compaq spare designated for this product.

CAUTION: Static electricity can damage the electronic components of the workstation or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

Batteries, battery packs, and accumulators should not be disposed of together with the general household waste. 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.
