Hi,
I've a Dell P75F010, with a FDI40 LA-G716P motherboard that don't power on at all.
I connected the MB to a bench power supply, 19v 1Amp and when I press the power button, nothing happen, no current drawn (some little fluctuation like 0.0005 to totally 0). So seem that I don't have any obvious short..
I just checked the first two mosfet that are immediately after the power connector and the first one was blown (is an AON6994, the first one will have a little hole on surface..) I replace it and now both mosfet has 19v on source.
I did some check around the board and i found 19v on some places (around the lcd connector, and so on) also i found the 5v on some components.
There is some other check that I can do? is the boardview/schematic available?
thank you for any support!!
