Aspire 3 A315-22 NB8607 ,5 pin mosfet

[adamski1952]

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.

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?
