iBook G4 won't switch on
My iBook G4 has suddenly stopped working and won't switch on at all (i.e when the power button is pressed, no sound, screen stays dark, nothing happens).
The only thing I've noticed is when connected to mains, the light on the power cable stays orange and the battery area keeps getting warm.
If I take out the battery and connect to mains, the light on the power cable stays green.
I have tried resetting the PMU by following the instructions here http://support.apple.com/kb/ht1431#faq6 without any luck.
Any suggestions?
