Probleme No Power on HP ProBook 650 G1

For safety, leave the 19v out of the equation. In the end, the mosfet is acting like a switch. Bridge the source & drain pins to force the 'switch to be closed'. Do not solder in a part at this location at all.

My problem is completely solved..!!!
The problem was that IC BIOS shows correctly with the programmer,
But it was actually a problem.!!!
that pin /CS (1) should not have any ohms with GND IN BOTH SIDE.
In this CASE, pin 1 of the BIOS IC was damaged due to the MOSFET.Also, I installed the MOSFET for IC BIOS' security ,like this and it worked great.
