Motherboard no power,19v ok 1st pchannel fet not fuction, PQ35 TPCA8109 p-channel mosefet sorse and gate 19v coming drain suply not coming,pls give me solution.

19 Volts? Input? Sounds like you're dealing with a laptop motherboard, and perhaps an Acer Aspire. Power comes on now, but battery not charging? Is there a PQ36 power MOSFET connected to the drain of the PQ35? If so suspect it to be bad. Also look in this power circuit area at all of the solid capacitors, for this circuit. Any black/brown/burnt looking? (SMD style. Surface Mount Device. Silvery rectangular shaped solid capacitors, and have a band across their middle) Also; IF you are not testing a power MOSFET correctly it will show bad.

ALSO:
Easier to replace the motherboard yes, but;

A) Where will the next generation of true electronic repairman/woman come from? Already we have nothing but a bunch of 'Parts Changers'. NOT tech's. Replace the motherboard; get a new laptop; get a new computer, etc.

B) That Power MOSFET costs about 97 cents USA.
88 cents for the SMD solid capacitors, probably.
Compare that to a L16.99, or L66.79 motherboard.

I commend you are at least trying; thanks!
