What is the battery replacement type for the D8B CPU mother board?
It is a relatively common type of battery – 3V lithium (Duracell #DL2032 or equivalent). Be sure to check the battery on your CPU mother board. It is responsible for storing the custom configuration settings in the CPU BIOS. If it is low on power, it needs to be replaced. Battery life expectancy is 3 to 5 years. If the unit has been stored (or turned off) for an extended period – battery life is shortened dramatically. See Battery Replacement for 166Mhz and 300Mhz.
