Default Aspire 3 A315-22 NB8607 ,5 pin mosfet

Hi.
I'm Having a devil of time with an acer motherboard that i can't get schematics for.
I traced a short to a 5pin mosfet next to the ethernet controller chip but google comes up with nothing on the part number (5FCC) so I dont know its type or values. the board is (NBHE811003)
Anyone help with this please.

Schematic - https://www.badcaps.net/forum/showthread.php?t=95163

I've been looking at this chip SY6288C20AAC on page 23 of that achematic. Do you think that could be it.?

No ,the SY6288C20AAC is marked RT*** .It would be easy if you had a Boardview,its available at some paid sites.If you make a request for it someone might have it,failing that just go through the rest of the schematic looking for all the 5 pin parts and google the part numbers,thats what i did but i might have missed one.

Is this rail linked to +1v8 by any chance?

See attached. Maybe a reset supervisor?
