Cut and tie the black and red pair or cut and tie the black and yellow pair to bypass the switch?


This is what happened to the switch.

@nine3o

Luckily in was unplugged when it exploded, i was able to clean out all the brass pins.

Surgery? I hope all is well :-?

So is it working then?

No, I need find out which wires to cut and tie to bypass the case key switch :-? A quick look at the C= service manual gave me no clues. I'm thinking maybe both?

So how did you pull it off in the end?

I tracked the problem down to the power supply. The PS was putting out close to normal voltages according to the simple MM test, but there was no +5V on PG. I ordered a replacement PS from Vesalia (EU 220V) and bench tested with a 110V - 220V step up transformer, the 3000T came right up.

Next step is to convert it from EU 220V to 110V US.

It's easy to do. I did it a couple of years ago when my A3000T supply died. Order the 220V EU supply just like you did. If i remember right (and I'm sure I don't) there was one jumper wire to change and one of the input wires had to move to a different tap. It clear what has to be done once you open up the supply.

Sort of. I did that and I get what appears to be good voltages, but no +5V on PG (Power good, or Fail). It works fine as a 220V, but no PG as a 110V.

OK, found the before pictures I took when I did my surgery back in 2005. Can't find the after pictures I took. Let me open up the supply and see what all was changed and I'll post some photos. Should be able to get this done tonight.

That would be sweet.

@mdivancic

I've approved the photos you uploaded.

One question. In the first couple photos, you mean add a wire between these points, right? THAT would make a lot of sense, I was missing a step altogether. Your last photo with the question marks. That does not need moved, it is like that in US an EU, no need to move anything.

You sir are a bad ass  :-D All bow to the mighty mdivancic :bow:

My A3000T PS is now converted to 110V thanks to you and it works 100%!!!

mdivancic, thank you very much for saving me time figuring out what was missing! If I can return the favor, let me know.

:banana:

I got mine fully working it seems, mouse and keyboard included. It turns out to bypass the keylock you simply leave the 2 pairs of wires open, cutting them will do. I was under the impression I'd have to tie them together, but that is what locks out mouse and keyboard.

I was getting TICK, but no PG (Power Good). It must have something to do with PG.

If you ever come across documents on the power supplies in you travels please share them.

Sure thing. I have the A3000T service manual also, but nothing on the power supply in it :-/
