Replacing the battery
The RTC battery is located near the memory modules under the memory access panel.
Figure 7-31 Battery location
The battery is located in the memory compartment. The battery that comes with the computer
provides power to the real-time clock. When replacing the battery, use a battery equivalent to the
battery originally installed in the computer. The computer comes with a 3-volt lithium coin cell battery.
WARNING! The 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 (140º F).
Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
Replace the battery only with the HP 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.
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.
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.
