What do the lit LED's on the logic board indicate?
My G5 has been randomly shutting down after being on for awhile. The fans seem to go into overdrive. I just blew out the case with canned air. I have not removed the logic board nor been able to inspect the thermopaste at this time but I did plug it in to see what the LED's might indicate. I show #1 lit green. No others are lit. Where do I get this info? Thanks.
