Mac Battery Question

[Junior]

I put my PowerBook away and the battery(3 months old) went completely dead. I got it out last night and now the battery will not charge. Is there a trick to this?

You're going to need to be more specific, brother: What model & year PowerBook? Why is the battery only 3 months old (i.e., was it a recall replacement)? How long was the compy put "away" for? In what conditions was it stored? From what kind of power source are you trying to charge it? Etc.

It's a PowerBook G4 Titanium. I had it put away for about a week. I replaced the battery 3 months ago with a new one from apple. I had it stored in a briefcase, and I'm trying to charge it in the computer with the original power supply that came with it. I left it on the plugged up last night with the computer turned off and it still shows 0% battery.

Here are some suggestions:

Personally, that's not a problem that I've had or heard before. Looking at the IU recommendations, though, I'd try turning it *on* plugged in and see if the battery charges then.

Was the battery dead when you stored it? Has this battery been charged before?

Thanks Professor I checked out the website. This battery worked fine when I put it up.

I will put it to sleep tonight and see if it will charge that way.

Next thing would be the PMU reset, I'd think. Best of luck and let me know what happens. PM me and I can give you a link to a Mac board that I've found helpful in the past....

Professor thanks for the help. I reset the PMU last night shut it down and let it charge overnight. I pulled it off the charger tonight and am using it now. The reset was the trick.

Mac battery's seem to have issues. I've been using Apples for years, and I've had two battery issues with my 3 year old PowerBook. Sorry to hear about your problem, let me know if you fix it somehow.

Glad to hear that did the trick!!! Now smoke a cigar to celebrate.
