Replacing the 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.

✎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.

ÅWARNING: 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 140°F (60°C)

■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.

ÄCAUTION: 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.
