Hi all, Dropped my ibook G4 12" - out of warantee It starts ok, but then after 10 seconds, it goes to sleep. when I wake it up, pressing the space bar, it comes to life, but with no backlighting on the screen. After 5 seconds, it then goes back to sleep again, and again and again...etc. any ideas before I take it in and spend lots of money fixing it? Regards, Nils.
