Dan asked:


I have a Powerbook G4 17″ laptop. (1.5GHz/512MB/80G/SuperDrive - 2004) I tried to start it up this morning and it won’t power up. I have noticed in the past few months that the battery would not hold a charge for more than about a half hour and would always say that I am using backup battery power. I probably should have addressed it then but hadn’t had the time to do so. I have read that I should be able to use the laptop if it is plugged in w/o the battery but I still cannot power up. When I push the button on the battery on the bottom of the laptop the light blinks for a few seconds and then goes out. Does anyone have any suggestions? I know I will probably have to take it to an Apple Store to get it looked at but any help is appreciated.

Thanks!
