My friend gave me his dead laptop that smoked itself, just sitting there. I'm a EE and I've recently equipped myself with fume extraction, microscope, hot air station, etc. to handle more advanced soldering work, so I said I'd take it on "as training" to see how far I can go.
Does anyone have the motherboard schematic for an HP Pavillion x360 14-dh2034nr schematic. It has two exploded capacitors next to PU4701. (C4710, C4711).
If not a schematic, does anyone know what part PU4701 is? It seems to be a Alpha and Omega Semiconductor part, based on the logo and similar motherboard schematics. It's most likely a buck regulator. But I can't find a datasheet on the website that matches the pinout. The part is labelled AF00 9C3H, but that's probably just a lot code.
The part measures about 3.6x5 mm and seems to have 6 pins along one short edge, 4 pins going to the inductor along the other small edge, and 6 small+2 big pins along one long edge and groups of 4+3 pins along the other connecting long edge connecting to the (destroyed) capacitors.
There are two identical parts right next to it that haven't blown their caps.
I haven't done tons of laptop repairs, so I'd be much more comfortable having a schematic to guide me.
Thanks,
Nick
