Replacing The Battery - Compaq AP200 - Professional - 128 MB RAM Reference Manual

Replacing the Battery

The battery that comes with your workstation provides power to the real-time
clock and has a lifetime of about five years. When replacing the battery, use a
Renata CR2032 or equivalent 3-volt lithium coin cell battery.
1. Turn off the workstation and any external devices. Disconnect the
power cord from the grounded AC outlet. Disconnect the network
cable and any external devices from the system. Then remove the
workstation access panel.
IMPORTANT: On a power-managed system, the power cord MUST be
disconnected from the grounded AC outlet.
NOTE: It may be necessary to remove an expansion board to gain access to
the battery.
