HP G56 power problems

[claudyu07]

Hi Guys.
I have here HP G56 with no power.
Board is DAAX3MB16A1 REV.A. DDR2

Mosfet PQ39 shorted, mosfet on the left of PQ39 totally burned and broken traces.

i identified them , rebuild traces but pq39 resistance between pins 5,6,7,8 and ground only 9-10 ohms when both fets are desoldered.

is this correct?

Thanks for your help

Should be ok since it's a power line for the northbridge. You should probably replace PU2. Or at least mesure voltage on PL2 with PR142 disconnected before you burn the northbridge.
