Replacing the battery
A lithium battery, installed in a socket on the system board, provides power for the real-time clock and CMOS
RAM. If the battery fails, replace it with an equivalent battery (3 V Lithium Cell battery, Sony CR2032).
To replace the battery, do the following:
1. Open the system unit cover (see pages 1-6).
2. Touch the metal chassis before touching the DIMM module or system board. Keep part of your body
in contact with the metal chassis to dissipate the static charge.
3. Slide (A) the battery in the socket towards the card edge as far as it easily slides, and then lift the
battery out (B).
