NOTE: The system board in the computer may look slightly different from the one shown here. To install the system board, reverse the removal procedure. NOTE: When replacing the system board, you must also change the chassis serial number in the BIOS. NOTE: After installing a new system board, always update the system ROM to ensure that the latest version of the BIOS is being used on the computer. The latest system ROM BIOS can be found at: http:\\h18000.www1.hp.com/support/files. 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 collection system or return them to HP, its authorized partners, or its agents. CAUTION: Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. 1. Prepare the computer for disassembly (Preparation for Disassembly on page 25). 2. Remove the access panel (Access Panel on page 26). NOTE: It may be necessary to remove an expansion card to gain access to the battery. 3. Locate the battery and battery holder on the system board. Battery 61
