Question about Apple PowerBook G4 Mac Notebook
This has become annoyingly regular: working on the 15-inch G4 powerbook (aged 2, relatively heavy duty), it suddenly stops reacting to trackpad, mouse and keyboard ALTOGETHER (even forced shutdown or restart by command keys impossible). This tends to happen between, say, 20 minutes to an hour after start-up and regardless of applications launched. It is not a standard "freeze" in that running applications seem unaffected (eg iTunes or Real Player music keeps playing and cursor blinking), just no communication with the computer is possible. In some cases I ultimately get a dark-veiled screen with the white letters informing me in 5 languages I need to restart by the main switch button. In any case, eventually I have to just switch it off physically. In at least one case the problem remained even after the restart, but generally things go back to normal (only to recur one cycle later). I'd mainly like to find out whether this is a hardware or a software problem, and whether there are others with similar symptoms? Thanks!
This is definately a hardware problem. The screen telling you to restart that you described is known as a "Kernel Panic". This basically means that some component of the machine is so out of whack that the Mac OS can't control it. Hard to say exactly which component is causing this without going throught the whole process of elimination. Good Luck! -inky

I just bought a mac book two weeks ago. everything was okay untill a few days ago.
Everything is fine still except for the letter keys on the keyboard which don't respond to any command i try to give to the computer.
All other keys are now operating on fn key. I really need help with this because i am doing a video and photo editing business with this laptop and now i am loosing a great deal of money.
2.1Ghz duo core processor. 1G ram. 120G hardrive.
