While taking apart ibook to replace harddrive on grapghite 466 , I ran into trouble. In taking out the backlight cable, the whole plastic receptor (little white plasatic at J4) on the motherboard came off as well. This is a little part (1/4 x 1/8inch). I can't tell if it was soldered on or just slips on the motheboard since tiny bits of plastic broke off. Can someone tell me if/how this can be repaired. Can I get one from another motherboard and replace, or do I need a new motherboard (tell me no, please). Maybe it can be 'glued' back on, anyone tell me what to do would be appreciated. Next time I will be sure to hold down when pulling plug out...thanks.
