System Battery Replacement
Overview
The P3000(D)BX2 utilizes a CR2032 lithium (Li/MnO
2
) coin battery ( Figure 20 ). This
3-volt battery provides power to retain the correct date, time, and computer parameters
in CMOS when the system is powered-off. This information assists the BIOS in
performing initialization and configuration during power-on or reset operations.
Service The system battery is designed to provide years of service without replacement.
However, if configuration or clock-related inconsistencies occur, the battery may need
to be replaced.

The procedure for installing the system battery ( Figure 21 ) is outlined in the following table:
The battery must be used or stored within the temperature specifications outlined on

packaging or labeling for further cautions and warnings.
Wegen Feuer- oder Explosionsgefahr, versuchen Sie nicht die Batterie wieder
aufzuladen, sie zu öffnen oder zu erhitzen. Bei falscher Installierung besteht eine
Explosionsgefahr. Ersetzen Sie die Batterie nur mit einem Gleichen oder
gleichwertigen Typ. Weitere Informationen und Warnungen entnehmen Sie bitte der

Step Action
1 Power-off the system and disconnect all power cords.
Note: Use a grounding wrist strap or other device to discharge static
electricity.
2 Remove the chassis cover.
3 Detach the SBC and expansion card hold-down brackets (if required). The
expansion card hold-down bracket reaches across the tops of the expansion
cards and holds them in place. The SBC hold-down bracket reaches from the
expansion card hold-down bracket to the chassis wall and secures the SBC.
4 Orient the battery with its positive pole (top surface) toward the front of the
connector.
Note: The battery will not discharge voltage if installed backwards.
5 Rotate the upper edge of the battery approximately forty-five degrees (45°)
away from the battery connector.
6 Insert the lower edge of the battery into the connector, so that the negative
pole (bottom surface) of the battery engages the negative spring contact of the
connector.
7 Press the raised edge of the battery downward until the battery seats firmly in
the battery connector.
Note: The positive spring contact of the connector will engage the positive
pole of the battery.
