I know it is an old machine but i had it laying around from back in the day when the power jack got broke.
So i figured one day i would tear it down and try to repair it and that day was today.
What i did was checked power to the dc jack of where it was getting power to the jack but not to the mobo so i de soldered the jack from the board and replaced it.
After replacing the jack i performed a bench test when i had put the mobo back inside the case but not completely together and what i have is led lights powering up for one second and then off with nothing else. No fan, no beeps not a darn thing.
I have checked the power to the board and i am getting 18.9 v to the board and throughout most of the pins, I am also getting some that are 5v and some 3.3 volts as well.
so i checked for continuity from + to - and found the circuits to be isolated so i think im good there.
Does anyone have a flow of diagnostics for this motherboard? i think it is a foxconn.
Does anyone have any ideas on this at all?
Thanks
