ibook G4 not booting

nerdy · #1 February 15th, 2008, 05:15 PM

When I boot PowerBook G4 displays the grey screen and the apple logo and goes no further.
Now read all the furom everywhere it say
For most situations, a restart is sufficient. If the computer has stopped responding, try these steps, in order, until the computer responds:

Force Quit (Option-Command-Escape)
Restart (Control-Command-Power)
Force Shut Down (press the power button for 10 seconds)

Option-Command-Escape on mac but no idea how to perform this which keys and how .

Command-Option-Esc brings up the window to force quit an application. This is only available when you're already at the desktop, but you're not even getting that far.

For the record, the Command key is the one with the little cloverleaf on it.

You might want to hold down the power and then turn it on again. Once you hear the startup chime after turning it on, hold down Command-Option-P-R and let it chime for a good three-to-four times, then let go. See if that resolves anything.

command = on some keyboards "apple" key
option = can be "alt" key

The Command key is the one with the apple and cloverleaf symbols on it.

The Option key is the one that has "Option" written on it.

Restart the Mac and right when you hear the "boooong" sound (aka, the Macintosh startup chime), hold down Command-Option-P-R at the same time. Don't let it go until you hear it chime 3 or 4 times, then let go of the keys. You have to hold them down together the moment you hear that chime or it won't register.
