HOT TAKE: if you design a laptop with a power supply that looks like this, you should go to jail.
-
I just followed somebody who has one of these. if I can ever remember who that was, I maybe can ask them to tell me what that component is
-
@foone Stencil font seems to say:
8C
D _ (or B _)Seems like a SOT-89 linear regulator but haven’t found any direct matches with that stamp yet, wonder if the piece with the missing letter chunks is still rattling around in the case?

@foone This might narrow down options, just found a bunch of candidates - most seem like regulators in this code range: https://smd.yooneed.one/code3843.html there’s a few SOT89s in the 8CD and 8CB zones…

@foone Found where the picture came from, same part number: https://my.rs-online.com/web/p/voltage-regulators/7139502

@Zagrophyte thanks!

So @Zagrophyte figured out what it is: it's a 5v 100ma voltage regulator.

I'll have to order one and see if it fixes this laptop psu

@foone I thought it said Cyrix EAT for a moment

@foone a T2000SX
PD: At least shows the voltage
-
@lunarloony I thought the same when I first yanked the heatsink off
-
@foone that looks a lot like my ThinkPad 300 connector

@FantasmitaAsex oh right, that nasty thing. I've had two Toshibas with it, but never seen the matching jack. I had to use some kind of clips to connect to it and power it on
-
@foone why does it have writing on it in... thermal paste? Paint? Marker? Glue?

@foone That looks like IDE pins 🤨
-
@FluidEscence I agree! Unfortunately it didn't exist back in 1993 or whenever they made this laptop

@twipped yep. They match the 44pin connector used by laptop IDE
-
@hazelnot I really don't know, and I can't get it off
-
@foone
IIRC it's the same connector as their PoS (Point of Sale) thermal printers (which Epson was a world leader and a defacto standard), which had been unchanged for lile 30+ years.It's a PITA tho and I agree 100% with your remarks.
