My daughter has a late-model AL PB (1.5GHz 15"). She had it out of the country for 6 months: about a month ago she reported a powersupply failure. Now that she's back, with a replacement PSU here for her, I can't get her battery to charge. If the AC power is removed, even the system clock loses track of its setting, which worries me futher. Don't these computers have litium batteries to store stuff like that???
When I press the battery's test button, one LED blinks rapidly for a few seconds.
The menubar battery status pulldown cannot show charge time: it is always stuck on "calculating:.
I have reset the PMU and PRAM. Are there other steps I can take, or should I replace the battery?
