No more short,removed some tiny cap or resistor,near gpu mosfet....what next?

Ok,laptop powers on ,im in bios now ����
I assume i will have no audio because L3606 burnt,where to find this,and do i need this cap or resistor at mosfet??

Good job. Yeah, L3603 has to be replaced for getting the Audio circuit back and if there are doubts it is also the best replace the cap. So near to a mosfet it might be more important, than another cap which is just used as filter.

Thanks Sephir0th,i could not do it without U'r help...can i salvage such resistor and cap ,or i need to buy...because in circuit resistor has short ohm reading,maybe remove it then measure?

Yeah, resistor measurements always out of circuit. This is a inductor though, so basically not a resistor.

For the cap, pay attention to met the specifications: Same capacitance, same or higher voltage rating.

Otherwise no issue to salvage from donor boards.

Yesterday i was measuring this cap near mosfet(this blown is 4 in row) and 3rd one had 2.7uf,is this my MM wrong,i even measured it out of circuit and again the same...is this 0603 size 4.7uf/6.3v?And L3603 is 3603 size 120ohm 100mhz(this one i surely can't measure cause i have aneng m118a)...jeez
