Hello thanks in advance for any help. I have a powerbook g4 that i recently upgraded with 1 gig of ram and up to 10.5 osx as well as a new battery for it. It was working fine but its just stopped powering up. Sometimes i used to take out the battery unplug it and then put the battery back in and eventually after holding it down it would power up.The battery has full charge but no matter what I cannot turn the computer on.
