Hi
I have a G5 quite a long way from where I am, and it won't start. I can't get to it right away, so I have to base my ideas on what info I get from there.
It doesn't start - the powerbutton light blinks twice, but no sound and nothing on the screen.
My question is: does anyone know of an overview, a list or something regarding the powerbutton blink pattern?

TIA,
Peter

I had a similar situation in which I reset the SMU (was called the PMU once) by following the intructions here.

How to reset the SMU on a Power Mac G5 (Late 2004) or Power Mac G5 (Late 2005)

It's a little button behind the fans. Mine wasn't blinking twice tho. It was on constantly with no blinking. Good luck. I know the feeling.

Yes, I had PMU (as I thought it still was called) reset in mind. Thanks for the direct link (I haven't done it on a G5 yet).
