M1230XA clock
7 messages in this thread
Redmond,
I have discovered a small problem with my M1230XA.
If I leave my A1200 off for more than three or four days (doesn't
happen often, I'll admit, but it does) the clock will lose track of the time.
Should I make the obvious leap of logic and assume it is the battery
that is at fault?
(A minor quibble on a fantastic product.)

Hmm. That's weird –since the battery is NOT a rechargeable battery.
Hmmm. I'll ask the technicians what they think.
What happens if you come back to the machine a day later or even an hour later
(after powering down).
Do this experiment: use the CLI and the setclock command to set the
hardware clock to some arbitrary time and then do setclock load a little while
later (without powering down) to see if it held the time
properly while running on system power.

Redmond,
I tried this while still online. The random time/setclock save/
setclock load gag. Looks fine after a few minutes.
You are right, it almost gives the impression of being a dying NiCad.

Joe:
Replace the lithium cell and see if that clears the problem.
It is barely possible that the cell is marginal or got shorted and has enough
voltage to hold the time but not enough to run the oscillator when powered
down.
See if that fixes it.

Redmond,
Right now, this isn't a burning desire, but the next chance I get I
will try to get a new cell.
Thanks.

Redmond,
Yes, I am aware that it is a non-rechargeable Lithium cell.
Part of me wants to see how long it takes to have this appear and
another part doesn't (seeing that it would require four or more days to pop
up).
I'll try that test out and get back to you.
