Red diode on G5 (2005 2,7 ghz liquid cooled) processor card
I'm trying to revive a 2005 G5 (2x2,7ghz liquid cooled). The computer powers up but does not go any further. I have noticed a red diode on one of the two processor card. Does anybody knwow what that means ? I've checked the processor assembly, removed both cards, there is no leak, but the red diode lights up on one of the processor card when I power up the computer. Thank you for your help !
