    I have found that blown power FETs do not damage the circuit board. Blown high voltage caps can though.

    I see.
    @johnbb were you able to get the board repaired?

    Actually I'm a bit scared to run it again with that blow MOSFET?
    Should I leave it like that or should I try to remove it with a heat gun first, and clean everything with isopropyl alcohol?

    It's definitely best to remove and replace it. I'm just curious if you tried it.

    If you had it repaired then try, but if you experience stability issues then just change it.
    I would go with replacement with better peace of mind rather than to be concerned with unknown issues.

    Thanks I'll go to an electronic shop to have it repaired but a refurbished GT72 motherboard is super expensive...
    If it's dead, I'll sell the rest of the laptop for parts...

    The damn motherboard works indeed even with the burnt MOSFET ! :eek: Nice to see the 6820HK back in action! :)
    I got the new one so when I have a few hours to spare I'll do the soldering.
    Thanks for the help, I'll let you know how it ends up.
