Recently I had a guy make me a custom ps/2 wire for my old acer keyboard. It finally got finished yesterday and I plugged it into the keyboard and I got no response. I decided to try the old wire and I also got no response.

I decided to use a multi meter to test if anything was wrong and the only thing that I found was that the original cords wiring appeared to be different then the new cables. I pulled up a diagram of a ps/2 plug and it appears the guy wired the new cord backwards.

Using the original cord I plug it into my old computer (because i know it is currently working) and it tells me keyboard failure. I suspect the keyboards motherboard got fried but I see no physical issues with it. I am also thinking my ps/2 port on my newer computer is fried because a ps/2 mouse works on the old computer but not the newer computer.

Would any of you have an idea on what might be happening and if their is a solution. Or will I end up having to give them a proper funeral.

Even tho you can't see any physical damage is still damage. once I wired up my front usb ports backwards so the voltage was going to the wrong lines I killed my usb mouse by doing that. the only way you can make that board work is replacing the board or getting a 40x microscope and checking each circuit. the ports shouldn't be damage tho, unless it went trough the keyboard and it sent voltage to the ports that unlikely becuase if that happen the computer would of turn off. the only way 2 to get around the ps/2 port on the desktop ports is getting a adapter usb too ps2.
