    Slinky 17893-1 Schematic needed

    From an Acer Sp314-51. Motherboard is a Wistron Slinky 17893-1.

    Schematic/boardview is on a few paid sites, just seeing if anyone has it before I shell out.

    Ok didn't end up needing the schematic as I fixed it already. I've had this model come across a few times on my bench so I'll upload it here if I have to buy it down the track.

    For the record, this fault was no power on. When power button pressed, +3.3V came up, but not +5V. PU4502 was shorted pin 2 to pin 3 and replacement sorted it. These aren't exactly cheap either compared to older Richtek chips that perform the same function. I had a donor board to steal one off in the meantime.

    PU4501 --> RT6256BGQUF (L8=xx) +3.3V
    PU4502 --> RT6258CGQUF (LJ=xx) +5V

    On another unit, I also had a throttled system with fan running flat out. It had previously been refurbished, and had D2602 knocked off. It's a schottky diode, no idea what, so stole similar one off another dead board I had lying around. I think it's part of the fan tach circuit.
