    Acer SF514-54

    Had to buy the boardview for the motherboard on this one so sharing here. Motherboard marking was NB8511-PCB-MB-V4. They are in Allegro format so you need the Cadence PCB viewer.

    Fault initially was a shorted PQ110 (AONR21357), but later discovered liquid damage around PU701 (TPS51487X). It's hidden under black tape that covers the memory IC's so is easy to miss.

    Although it was outputting 1V/1.8V ok, the PG line measured 4 ohms to ground. What confused me was that the chip itself didn't measure that way off board, hence why I needed the boardview at the time. Fault turned out to be the IC in the end and it fired up once new one was fitted.

    Anyway enjoy.
