Compaq nc4010 battery wont charge

Archived from groups: comp.sys.laptops (More info?)

If it is under warranty what are you waiting for, the warranty to expire.
Either the battery has a shorted cell or the charging circuitry is broke.

I was waiting to see if there was anything I'd missed which wouldn't
involve me sending the thing away and being without my laptop for a
couple of weeks.

Ignore the reading temporarily.
Turn off all power management in the bios and the os and anywhere else
you can find.
How long does the computer run before it shuts off?
How long did it run before the symptom started?
If the numbers are the same, your charge indicator is out of sync.
Sometimes there are software programs to recalibrate it. ON my Gateway,
it's in the bios setup. Google is your friend.
If the numbers are different by the 2.5X suggested by the charge level
number, you might still want to try recalibration.
Failing that, your warranty is your friend. But read it carefully,
the battery may have a much shorter warranty period than the rest of the
system...like 90 days.
