Hi guys, As of yesterday my battery no longer holds a charge. Was running fine on the power cord. Now this morning when I boot up the computer. It goes on the apple loading screen, gives me the apple sound but instead of loading into the desktop. It goes back to the gray screen with the apple in the middle loading. It does this repeatedly and won't load onto the desktop. Need some advise on what I need to do .... I'm also not sure if I have any of the original boot disks. Any help is greatly appreciated. I'm running a g4 with 10.5 no problems until today.
