Read about water cooling BS... took mine apart and it had JUST started to leak. Machine booted fine. Took it all apart and cleaned it replaced o-rings refilled coolant. put it all back together and Gong, normal startup noise but no boot, no video. Checked battery 3.7v, even tried good known working battery. Did PMU reset, no dice. pulled all ram but apple shipped, no go. No Open firmware, no command option p r.
Red light alternates each power-up randomly between both the processors, if I let it sit it will warm what ever processor is not "Hung" till it ramps up the cooling system to full and cools it back down to cold.
This to me means that the processors are operating, just not together.
Thought I had too much paste on processors so I took it all down again and went through it again with a little less goop, no change.
Fans and pump operate at slow speed until its been on for a few mins.
When air deflector is removed I can hear the water pump circulating.
If I pull battery and let it sit 10 mins, the first power-up does have the startup chime, but sometimes the processor hangs (red light) in the middle of the chime. After the first power-up it does not chime and instantly triggers the red light on either one of the cards.
Pulling the water cooling connector while hung caused BOTH processors to redlight but was not repeatable
Worked fine before I took it apart... Whats the d**n deal?!
Motherboard got angry?!!
