CMOS Battery
This battery provides power for the system CMOS, which retains the system power-up and custom settings.
However, should the LDR begin to show signs that the system clock resets on power-up or that the custom settings
are lost, then it is possible that the battery may need replacement. To do this the LDR must be returned to the
manufacturer.
