Component Replacement
Replace the RTC Battery
The computers use nonvolatile memory that requires a real-time clock (RTC)
lithium battery to retain system information when power is removed. The RTC
battery is next to the SO-DIMM1 slot.
This battery is intended to 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.
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 the rated temperature
ranges in
•
Do not dispose of a used battery in water or fire.
