CMOS Battery Problem

A message “CMOS Checksum Failure” displays during the

booting process-

?? Try to reboot the system.

?? If the message CMOS Checksum Failure” appears

during the booting procedure repeatedly, it may indicate failure

of the CMOS battery. If so, you need to replace the battery. This

battery normally lasts two to five years on continuous operation.

The battery is of type CR2025 (3V). You may replace it by

yourself. The battery is located next to the Mini PCI Card

socket. See Chapter 3 on how to access the Mini PCI Card

socket. If you are not sure how this is done, return the

computer to the dealer.
