IBM Model M malfunction

[Gunny]

Good evening everyone,

Some times ago, I bought a Model M, which was dirty and lacking some keys. Now it's complete and clean as new (well, nearly). But I can't use it. Reason is, after some minutes of use (plugged on PS2) it will shut down every USB and PS2 port behind my computer, which is, you have to admit, pretty annoying.
It seemed to work fine before, which leads me to believe it might have something to do with the required disassembling it had to go through.

Have anyone had a problem like that or does anyone have an idea about how I can fix this ?

Thanks a lot !

hm.. you could try a controller from another Model M or/and check the membrane for damage

Not likely to be the membrane. I'd look at the controller board for any thing that could be shorting it out.

However, I think the most plausible theory here is that your motherboard has a dodgy PS/2 port. The best way to get around this is to buy a good PS/2 - USB adapter and use the keyboard with that instead.

As usual, I'd recommend testing the keyboard with another computer to see if the problem is reproducable elsewhere.

Yep, I forgot to tell, but the problem occurs on both my computers. I'll take it apart to see is there's anything out of place.

Though it might not be relevant at all...Did you reattach the grounding wire to the metal backplate? Make sure it isnt loose.

Well, I took it apart again to inspect it. Saw nothing wrong, put it back together and... It works. I'm typing on it right now. Go figure.
