I don't know if this work with your board, but i have no problem using AON6414 for replacement PK5N2EA

and your second mosfet is PE636BA, you can use A5 mosfet ( asus board ) or ao7410 for replacement, DWYOR.

PK5N2EA is 50% stronger in continuous drain as AON6414 so no way for me and AO7410 cannot be even compared to PE636BA

but thanks for identifying that second mosfet

Hello! I have a similar issue on a Lenovo Legion Y740-15IRHg. Got 4 mosfets blown and I can't identify and find the values of the big ones from the picture. If anyone could help with that I would greatly appreciate.

Thanks for the quick reply! Not sure if I'm an idiot (probably am) but can't seem to find these mosfets in the PDF when I try to search for PQ301 or PQ316 marked on the board. I'm definitely not good at reading schematics.
