    Lenovo Legion Y740-15ICHg LA-G132P blown PQZ1 mosfet

    PQZ1 was taken out by someone else.

    its probably a dual mosfet. but all traces destroyed ,so hard for me to tell what goes to where

    does anyone have a boardview or schematics. or a high quality picture to tell which ic is PQZ1

          Y750 has a PQZ1 dual mosfet.

          See attached - again from a Y750 - likely very close or same as the Y740.

                        How do you test MOSFET in laptops ?
                        by Jane
                        I tried to use this method:

                        Testing an N-channel MOSFET:

                        Step 1: Discharge the Gate (turn off the MOSFET)
                        Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
                        Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

                        Step 2: Charge the Gate (turn on the MOSFET)
                        Now, place the red probe on the Gate (G) and the black probe on the
                        ...
