THE PINOUT IS FOR THE POWER CABLE

NOT THE POWER CONNECTOR ON THE LAPTOP

meaning:
1. it's mirrored
2. I may have just reverse-volted it and let the magic smoke out

yeah, I borrowed someone who has... nosmia? Whatever the term for "has a sense of smell" is. It's got Magic Smoke Stank now.

Pulled everything out. It's a small computer! This is everything but the keyboard, hard drive, floppy drive, and screen.

Three PCBs. The top right one is an L-shaped modem, the bottom-right one is a small stick of a PSU, and the left one is a sort of reversed-F shape of a main board, with a few large chips on it

apparently instead of having a "POWER GOOD" pin like ATX PSUs do, they went for the opposite, where they have a pin that tells you if the power is sus *amongus noise*

A list of pinouts. Pin 17 is listed as "VCC SUS"

someday when I have money again I'm getting me an inspection microscope with HDMI out so I can do better close-up pictures of these things.
But here's the power supply board. Something on here smells (supposedly) like Magic Smoke.

Do they make smelloscopes?

Two views of a small PCB, top and bottom. It's got a bunch of inductors, capacitors, and a ton of little resistors.

wait

ZOOM, ENHANCE!

I don't think it's supposed to look like that (Amusingly, I'm listening to Well There's Your Problem in another tab)

A SOT223 chip that's exploded

the question is: what the fuck is this thing?

the label has been sadly... exploded.

I think it's either a MOSFET or a very small voltage regulator?

@foone I came here to ask if anywhere it specified which view that pin out was 😅

@foone This is why I usually connect ground to the shield of a DB connector. Still not foolproof
