Single keystrokes produces two characters

I have a Toshiba Satellite Laptop, and the DC input jack broke. Since it was out of warranty, I decided to replace it myself.

I followed all the on-line instructions, being especially careful not to mess up the ribbon connection between the keyboard and the motherboard.

After I replaced the jack, and got everything back together, I noticed that I couldn't log in with my password. Since it appeared as asterisks, I couldn't tell what was wrong, but it appeared that there were too many characters showing up (the password became ten characters long instead of eight.)

Figuring that it might be a keyboard problem, I borrowed a USB keyboard, and sure enough, I logged on without problem.

I found that if I type either "s" or "w", I get "sw"; if I type "k" then I get ",k"; if I type "L" then I get ">L"; if I type "p", I get "[p"; if I type a "q", it is followed by a tab. Most of the other keys work ok, while there are other weird combos popping up involving function keys.l think you catch my drift.

I uninstalled and reinstalled the PS2 driver, but to no avail.

I was so sure it was the keyboard's fault, that I ordered another. It just arrived, and produces the same problem. I downloaded Microsoft Intellitype Pro, and it told me that there is nothing wrong with the keyboard, but insists that two keys are being simultaneously struck and released.

I am afraid that I might have messed up the connector to the motherboard, or screwed up the motherboard itself, probably require replacing the motherboard in either case.

I hate paying a repair guy to confirm my fears, or ordering a new chip and finding out that it wasn't needed, or that I screwed something else in the process.

Does anyone have a different diagnosis or at least another test to try out?

Since the keys being pressed are adjacent to keys "not" being pressed, your diagnosis of a connector/cable is probably correct. At this point referring it to a technician ("repair guy") would likely be your best bet.
