I can t remember what was the original problem with this board, but i assume it wasn't powering on...
Once i got it working, passed asd test but left option shift and fn wasn't working so i replaced u5750.
It worked like a charm for 2 days the suddenly no keyboad or trackpad and fan on high speed.
I changed Q7800 as the output was 1.7v instead of 3.3v...
Again it worked for 1-2 days without problems, then q7800 died again.....
Replaced and worked fine untill today (1-2 weeks) when the custommer said no keyboad and trackpad AGAIN!!!
I assume is q7800 is dead again...
Any ideea what can cause this filthy failure?
Thanks a million!!!
