Hey guys, This started happening about 6 months after I bought the 1ghz Pbook g4 12". I brought it into a service center and it was shipped off to apple to be serviced under warranty. That was about a year ago. The issue was with the pbook shutting off randomly when the power cord isn't plugged in. Occasionally the laptop will stay on for a few minutes without the power cord, but once it shuts off I can't turn it back on at all unless I plug the power cord in. With the power cord in the computer works perfectly fine. When I set it in to apple they said I had dropped the computer. Which omg, I can't even explain made me so pissed. So basically they did nothing to it. Once it was brought back to the service shop in my area they tried a new battery in the pbook and supposedly it worked, but I don't know how long he tried it. It's to the point now though, that I want the pbook fixed so I can use it on my lap or places where there is no plug. Anyone have any fixes or similar or same issues as this? What route did you take to fix it? I do have my pbook insured with state farm so worst case I'll just make them pay for it, but as an apple customer I feel I shouldn't have to as it did brake during warranty period. But I know that won't happen so I'd like to see if I can fix it myself or know for sure that I need a new battery. Thanks in advance for any help with this issue. I called my local apple tech (not an apple store) and he believes it's either the battery, or the logic board. He said 85 an hour to repair it and estimated hour to one and a half hours. Or it's the battery which is 150 bucks. Is there a way to do this myself though? Either way it's sort of lame since it's not my fault and it was broken under warranty and they didn't fix it then even though I shipped it. So I guess I have to bite the bullet and pay to get it fixed which isn't to much, or I'd be glad to take suggestions from you guys who know powerbooks better.
