HP EliteOne 800 Hardware Reference Guide

Replacing the battery
The battery is located on the system board on the lower right side of the fan. 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 (140 ºF).
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, be sure 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.
HP encourages customers to recycle used electronic hardware, HP original print cartridges, and
rechargeable batteries. For more information about recycling programs, go to

recycle.
1. Remove all removable media, such as compact discs or USB flash drives, from the computer.
2. Turn off the computer properly through the operating system, then turn off any external devices.
3. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the
power to drain before adding or removing memory modules. Regardless of the power-on state,
voltage is always supplied to the memory modules as long as the computer is plugged into an
active AC outlet. Adding or removing memory modules while voltage is present may cause
irreparable damage to the memory modules or system board.
4. Remove/disengage any security devices that prohibit opening the computer.
5. Place the computer face down on a soft flat surface. HP recommends that you set down a
blanket, towel, or other soft cloth to protect the bezel and screen surface from scratches or other
damage.
