Hi guys, I am posting this on behalf of my dum brother, who for some unknown reason lifted up the keyboard of his G4 iBook whist the machine was on. The iBook crashed and will not now restart. He says that when he presses the power button he gets a flicker across the screen and nothing more. I talked him through the obvious things,Pram reset, PMU reset battery on and off but nothing seems to work. Do you guys have any ideas? What will removing the keyboard do whilst the machine is on? Has he fried it? Please help as he is calling me every ten minutes as he sees me as a Mac genius because i have been using one for about 2 years!!!
