[comp.sys.ibm.pc.hardware] Help--my CMOS clock and setup information is disappearing

jem97@leah.albany.edu (Jim Mower) (02/19/91)

I have a CompuAdd 286 that is having problems retaining its setup
information in CMOS.  I have tried replacing the batteries but the
problem persists.  This problem appeared within a day of adding a
second serial port, which works correctly.  Typically, CMOS loses its
setup information about once every two days now, always after an
overnight power-down.  Also, the real-time clock is losing a few
minutes each hour.  Assuming that the batteries truly are not to
blame, what is likely to cause these problems?  My friendly CompuAdd
salesman guesses that the motherboard should be replaced.  This seems
a little drastic to me.  There is no exotic hardware inside the machine 
(modem, serial port, 20MB hard drive).

If you have any thoughts on this, please respond by email and I will 
summarize any responses of general interest to the net.  Thanks to all.
