Lithium (CMOS/Clock) Battery

Before removing the system battery, start the system and enter BIOS Setup. Page through all
the screens, making note of all parameters. Parameters include date, time, hardware
configuration, and other data.
CAUTION Do not change any parameters. Doing so could cause your system to operate improperly or
not at all. After replacing the battery, you will need these BIOS parameters to ensure the
system is restored to its previous state.
The battery is located near the bottom front of the system board. See the system board
diagram in Chapter 5, "System Board," for details. When you remove the battery, the system
will lose its operating parameters stored in CMOS. As a result, the system BIOS parameters
are lost.
After you install the new battery, you must reset the date and time and reconfigure the BIOS.
See the InterServe 800 System Setup for details on updating and configuring the BIOS.
WARNING There is a danger of explosion if the battery is incorrectly replaced.
WARNING Replace the battery with the same or equivalent type only, as recommended by the
battery manufacturer. Dispose of used batteries according to the battery
manufacturer's instructions.
To replace the battery:
1. Remove any option cards that restrict access to the battery. See "Option Cards" for
details.
2. Note the positive orientation of the battery. Carefully remove the discharged battery by
grasping it firmly and pulling it out of the socket.
3. Install the new battery in the same orientation as the old battery.
4. Dispose of the battery according to the manufacturer's instructions.
5. Install the option cards that you removed.
