Hello.
I got a faulty Acer Aspire 5517. took it apart and found a burnt mostfet (PQ35).
through the schematics i found online i order some new mosfet a replace it.
i re assemble the laptop to test it. and when i pressed the power button the laptop work for a few second (fan and power led turned on)and then stop.
Took the laptop apart and checked the mosfet with a DMM and Drain and Source was shorted.
i replaced the mosfet once again cause i though i didnt solder it well. but the same thing happened.
above the mosfet i replace there is another mosfet(PQ36). Now the Source of PQ35 is Connected to the Drain of PQ36 acording to the schematics.
Checking with the DMM i see that its connected to ground but according the the schematics its not.
the schematic i have is this one. on page 42 you can see the relative circuit.

what else should i check around the mosfet? nothing else seems to be burnt.
Not a native english so sorry for anything that doesnt making any sense in my writting.
Thanks in advance
