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! Thanks, Ann
You replaced the dc in board—did you reset the PMU? If I read correctly the computer is asking for that. You remove the battery and power adapter. Them press and hold the power switch for 5 seconds and release. Reinstall the battery and adapter. Turn on the computer and keep fingers crossed. If it starts normally you are good to go. If not get back to us and we will look deeper. Ralph
