replaced dc-in now comp is making noises and says restart
My daugter's iBook dc-in burned out. The comp was working fine if we used batteries charged in our other 12" iBooks. I replaced the dc-in board. The battery now will charge but the computer is messed up. I can feel clicking etc. under the rear quadrant on the usb input side. The fan came on fairly loudly once. The computer keeps saying it needs to be restarted by holding the power switch several seconds. The same message keeps coming up. I've gotten it to work for a few minutes a couple of times......then the need to restart message with a large image of the power button comes on again. I took the comp apart again to see if I had done everything properly, but couldn't see the problem. My son's computer recently had a bad jack and I replaced it with no problem.
Any help would be appreciated!
