•
Replace the battery with the same type as the battery recommended by HP. Use of another
battery may present a risk of fire or explosion.

A risk of fire and chemical burn exists if the battery is not handled properly. Do not disassemble,
crush, puncture, or short external contacts, or expose the battery to temperatures higher than
60°C (140°F).
•
Do not dispose of used battery in water or fire. Dispose of used batteries according to
manufacturer's instructions.

Loss of BIOS settings occurs when the battery is removed. BIOS settings must be reconfigured
whenever the battery is replaced.
To replace the system battery:
1. Remove the PCI riser board assembly.
If necessary, remove any accessory boards or cables that prevent access to the battery socket.
