Chapter 4 Component Replacement
Replace the RTC Battery The computers use nonvolatile memory that require a RTC battery to retain
system information when power is removed. The lithium battery is on the
computer’s motherboard next to the DIMM1 slot.
The battery must be replaced during the life of the computer. The battery life
depends on the amount of time the computer is on, or on-time.
If the computer does not retain 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 36 .
2. Remove the computer cover as detailed in Remove the Cover on page 37 .
3. If necessary, remove any accessory boards or cables that prevent access to
the RTC battery socket.
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.
