Its more of a project from Electronics school where we get a faulty laptop motherboard and have to try and find where the faults are, I am a little confused because the motherboard is not powering on , 19volts is on the motherboard from power supply . power button is getting 3volts . so I look for the first Mosfet ( B04 N03 EID 5106) that is closest to the 9 volts power from the board which is PQ4 , source 3pins are 19volts - train 4 pins 19 volts - gate is 25 volts . and the same for the PQ3 which is just to the side -so I was thinking and I could be completely wrong but is 25 volts not to high on the gate for this Mosfet ? I tried to get the data sheet up for the Mosfet and if it the same Mosfet and I think it is - gate source volt -limits 20v. ?
