My laptop died recently and Im testing the motherboard. Im led to believe these two MOFSETs on the board may be part of the issue PQ301 and PQ302. Using a multimeter continuity and diode mode; PQ302 beeps between S and D on continuity mode and 0 resistance on diode mode. Im led to believe that means its defective. PQ301 does nothing on both modes between the pins. Ive been testing them in opposite pairs i.e pins 8 and 1, 7 and 2 etc. Am I testing them correctly and if so should I go ahead and replace the mosfet and see what happens? Heres the diagram Ive been looking at. Just hoping for some guidance. Thanks. |
