Component Replacement Chapter 4
Replace the RTC Battery The computers use nonvolatile memory that require a battery to retain system
information when power is removed. The 3V, 200 mAh lithium battery is on the
motherboard.
The battery must be replaced during the life of the computer. Battery life depends
on the amount of time the computer is on, or on-time.
If the computer does not display the correct time and date, replace the battery.
Follow these steps to replace the RTC battery.
1. Follow the steps for Pre-configuration on page 35 .
2. Remove the computer cover as detailed in Remove the Cover on page 36 .
3. If necessary, remove any accessory boards or cables that prevent access to
the RTC battery socket.
4. Remove the battery.
a. To dislodge the battery from its
socket, insert a non-conductive
tool (such as a small flat-blade
plastic screwdriver) between the
battery and spring latch (A).
b. Remove the old battery from its socket (B).
ATTENTION: A risk of fire and chemical burn exists if the battery is not handled
properly.
• Do not disassemble, crush, puncture, or short external contacts.
• Do not expose the battery to temperatures higher than 60 °C (140 °F).
• Do not dispose of a used battery in water or fire.
