I have a such device from a friend, but it can't be powered on.
I investigate it and I have some conclusions, please help me to fix it:
a) the voltage on Q9350 (page 47 from IMPIP - M5, schematic) has wrong values:
+19V S=Source Pin 1-2-3 - this is OK
+8.4V D=Drain pin 5-6-7-8 - this is not OK, must be about 19V
+5.3V G=Gate Pin4 - this is not OK, must be about 19V
b) the PC starts if I connect directly Q9350's S and D:
- CPU and GPU fans start
- power button works
- I haven't seen yet any image on the screen
c) with b), if I remove both DDR3 SO-DIMMS modules, then there are some POST beeps (I assume that they are memory beep error, I don't have yet the meaning of them)
d) on schematic Q9350 is TPC8107, on my main board Q9350 is FDS6679AZ, they seem to be very similar
-If matters
In this time I will continue to investigate the issue
P.S. I know that this is an old post, but I think that it is better to post here instead of opening a new post.
