On boot up I get a error message “CMOS/GPNV CHECKSUM BAD” message.
Allsettings in Bios revert to default.
However this occurs only occasionaly. The system can run for 3 weeks with no problems
I have relaced the CMOS Battery to no avail.
I have run diagnostics “Microscope” whick shows no errors.
Any sugestion what the problem may be and how I can prove it for a warranty claim?
Thanks
