Removing and Replacing the Battery

Upgrading and Servicing Guide

A lithium battery on the motherboard provides backup power for the computer's

timekeeping capability.

Replace only with the same, or equivalent, type of battery. Discard used

batteries according to the manufacturer's instructions.

WARNING: Never use metal objects, such as pliers, to remove or replace the

battery. Metal contact may cause a battery short and damage the battery.
