Sick Powerbook
I'm looking for some instant guidance here, if anyone can help.
When I tried to wake up my G4 Alu Powerbook this morning it was dead. I tried a restart with the power key and the screen stayed black and instead of the chime I got three beeps from under the keyboard. The indicator light by the latch is constant (ie not pulsing) but it does flash four times every 10 seconds or so.
Can anyone tell me what is happening? I'd be very grateful for any help.

Did you install or upgrade anything in the computer at all recently?
If so you may want to go back to you pervious configuration and try again.
I don't know if resetting your PRAM will do anything. but on the support site you should beable to find out all the indicator codes, (ie light flashing 4 time, beeps, etc.) I can't recall them off the top of my head.
It could even be your logic board.
lets hope not though.

Thanks - I've found out (I think) that the 3 beeps mean a memory failure -

I've had that years ago, when an old Power PC started up with the theme from the Twilight Zone...
I guess memory just goes when it goes, and that could happen on any startup.

Fixed!
Got an answer from a (relatively) tame Mac genius.
For reference - it was a lower memory slot problem - apparently this is an issue with G4 Powerbooks. I swapped the memory (fortunately just 1 card) into the top slot and all is well.
