I spent hours researching this problem on the net, and have settled for a chip on the logic board that, after a lot of wear and tear, doesn't make contact correctly with the mother board.Īpparently it is 'easily?' fixed by taking your mac to bits and inserting a plastic shim across the offending chipset.the pressure on the shim when you put the ibook back together is the fixer.īut if, like me, you don't have the `bottle' to start taking your ibook apart and messing about with metal across circuit boards, just get a pack of Post It notes, (I use the small 1.5?x1.75? ones), place your ibook on the pack on a flat surface, and press down on the left and right side as you switch it on.
