Motherboard Battery
The motherboard uses non-volatile memory to retain system information when system power
is removed. This memory is powered by a lithium battery residing on the motherboard.
Replacing the Battery
Begin by removing power from the system as described in section 3.1.
1. Push aside the small clamp that covers the edge of the battery. When the battery is
released, lift it out of the holder.
2. To insert a new battery, slide one edge under the lip of the holder with the positive (+)
side facing up. Then push the other side down until the clamp snaps over it.
5. Secure the expansion card shield onto the rear of the chassis with a screw.
