ASUS/ROG GL553V replacement mosfet

[Jenzo]

Hi, the circled mosfet on the added picture gets really hot and measures short, but I'm having issues finding a replacement.
The mosfet reads:
4843NS
RSBD2

Thanx in advance!

Remove the mosfet off the logic board. Test again the resistance across this mosfet's leads to see if it is shorted or not.

The mosfet is a common N-channel 5*6 mm style that can be found on most motherboards. Review the 2*DCin mosfets on other motherboards. Often from AON and the charger IC will be the 'BQ' style from Texas Instruments. They will be a drop in replacement.

Post the part numbers of other mosfets you have available to you. Otherwise you can order from Digikey or Mouser or AliExpress.

0 resistance between source/drain, it's completely shorted. Could you link me one from mouser for example? I'm not that familiar with these, normally I only work on macbooks :'). Thanx in advance!

Sure. After dropping off junior to the mall, will locate a valid sub. Any chance you have any donor boards of any brand?

Cool, thanx in advance! The only ones I have available are Apple (mainly from A1278 and A1466 devices), no other brands.

Thank you!

The original was SOP-8 format, this doesn't matter as long as it fits I'm guessing?

Re: ASUS/ROG GL553V replacement mosfet

Sop-8 = 8 pin package. It is the same size and the same pinout as the original.
