Toshiba Equium A100 laptop keyboard problem

When I press u on keyboard I get 8u, press i I get ki. press o I get lo, press 2 I get w2, press 1 I get 1 with a tabbed space. All the other keys work fine.
I am running Windows XP Home SP3. I have tried all combinations of key sequences (turning off hot keys etc) but still have the same problem. I have also taken the keyboard out of the laptop and cleaned it, and checked for damage on the connector ribbon, and it looks OK. I also uninstalled the driver then reinstalled it but the problem persists.

I hope someone could help me with this problem. I'm hoping for some help before I perhaps have to buy another keyboard. Even then I'm not sure a new keybord will solve the problem.

Does your laptop have PS2 keyboard port? if so, try that with external keyboard and update drivers from Toshiba website.

If there is no PS2 port, use a USB keyboard. If you get the same issues then, and if the keyboard acts the same when your not in windows (boot the PC with a puppy Linux LiveCD and test typing there), then the keyboard controller on the mainboard is defective, which would require you to change the board.

Thanks for the replies.

I tried it with a USB keyboard and it works OK. Ended up buying a new keyboard and that works fine. I'm just glad the keyboard controller on the board works!

An update on the problem mentioned above. The new replacement keyboard has started giving the same problem as the old one now!

I tried booting into Puppy Linux and the first time the keyboard worked fine, but after that it does the same problem.

If I use an external USB keyboard in Windows XP it works fine.
I really can't make out what is going on.
