Hello World,
Recently, my IBM AT is having a strange problem with its clock.
The problem is that the clock does not seem to run when the machine
is off, so that when I turn the machine on the next morning, the date
and time are set to that of the previous night. Doing the 'set-up'
routine with the diagnostics disk does not cure the symptom, and I
replaced the battery about two months ago. Not being a hardware
person, I'm stumped on what I can do to fix it. There was no mention
of clock in the 'Hardware & Maintanence Service' manual either.
If anyone have any idea, I'd appreciate some help.
Thanks to all who respond in advance.
John
(p.s. It's an IBM AT at 6MHz, with 80287, a mouse, ethernet card,
ega, and PCDOS 3.2, if it makes difference.)

At first I thought it couldn't be the battery, as my computer is only about 6 months old. But by wiring in another battery in parallel, I was able to get the clock running again. This is a temperary fix, as I have not been able to figure out if there's a large current drain somewhere. I added a connector in there with a holder for AA batteries so I don't have to pay $20 for a replacement battery while I'm trying to work the bugs out. That may be the most economical (if not most troublesome) way to "solve" the problem. -- Yuan Chang UUCP: {ihnp4,uunet,ucbvax,dcdwest}!sdcsvax!nosc!uhccux!yuan ARPA: uhccux!yuan@nosc.MIL "Wouldn't you like to INTERNET: yuan@uhccux.UHCC.HAWAII.EDU be an _A_m_i_g_o_i_d too?!?"
