I just tried changing my Powerbooks battery while it was sleeping, and when I removed the battery, the computer just shut off. I tried resetting the PMU, and the PRM and NVRAM, but it still dies when pulling the old battery out. I am fully updated and running 10.3.2. Does anyone have any suggestions? I really don't want to send my laptop into Apple for service considering it was just replaced because the previous one was a lemon. Also, does anyone have experience with Tekserve in New York City, or Alliance Computer Systems in Freeport or Wantaugh? Do they offer walk in same day repair? If that's possible, I would much rather do that than be without my Powerbook again because I am a student. Last time I had the issue, my Powerbook was gone for a good month of non use at Apple, and I am not in the mood, nor do I have the real option to do that again because now my schoolwork is ramping up.
