CMOS Battery Problem

A message “CMOS Checksum Failure” displays during the

booting process or the time (clock) resets when booting -

Try to reboot the system.
If the message “CMOS Checksum Failure” appears

during the booting procedure even after rebooting, it may

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

the battery. This battery normally lasts two to five years. The

battery is of type CR2032 (3V). You may replace it by yourself.

The battery is located next to the DDR DRAM socket. See

Chapter 4 on how to access the DDR DRAM socket. If you are

not sure how this is done, return the notebook to the dealer.
