View Full Version : CMOS battery failure

06-11-1998, 12:15 AM
For the past few months I was getting an intermittent error messsage when first booting (Pentium 166 about 1 year old) -' CMOS checksum error - defaults loaded - CMOS battery failed ' Pressed F1 to load defaults then everything normal.
As it was intermittent I just lived with it.
A few weeks ago it became permanent, and I lost my time.
Have since tried 2 new CMOS batteries.
The fault is mainly still there - about 90 percent of the time.
Have given the old machine a good clean out.
Dealer is no help.
Is it just a faulty motherboard/battery connection, or something more sinister?
