2.5 Replacing the 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.

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.

Note: Handle used batteries carefully. Do not damage the battery in any way; a damaged

battery may release hazardous materials into the environment. Do not discard a used battery

in the garbage or a public landll. Please comply with the regulations set up by your local

hazardous waste management agency to dispose of your used battery properly.

Warning: There is a danger of explosion if the onboard battery is installed upside down (which

reverses its polarities). This battery must be replaced only with the same or an equivalent

type recommended by the manufacturer (CR2032).

slot.

Caution: Exercise extreme caution when installing or removing memory modules to prevent

damage to the DIMMs or slots.
