Hi. I have an iBook G4 running OS X 10.4.11. It is the 1.07 GHz model with 768 MB Ram. I got it from a friend, and it is on the list to fix. It has several problems. 1. The laptop will sleep by itself. Yes, I set my laptop to never sleep and dim at 15 mins, but when I unplug it, it seems to last about 30 - 45 seconds before falling asleep. 2. Battery wont hold a charge. Before I buy a new battery, I would like to know if there is anything to do to fix my current battery. I will unplug it for about 30 seconds, and it will sleep. When I plug it back in and power it on, my battery will say it needs 63:xx to charge, even though I only unplugged it for 30 seconds. 3. Display cuts out. The laptop's screen will only work/display the right colors when it is at a 100 degree angle. If you push it anywhere outside of that, the screen will glitch and sometimes not even work. 4. Software update doesnt work. I have already connected the laptop to my wifi, and when I click on software update, it will load up as usual, but the progress bar will get stuck at the beginning point. Thank you for all your help.
