Incorrect keyboard scan codes being generated

A Toshiba Satellite C655 laptop is showing the following behavior:
 
Pressing p generates /p
Pressing w generates \w
Pressing h generates {backspace}h
Pressing k generates {enter}k
Pressing / generates /p
Pressing {leftcursor} generates {backspace}h
Pressing {downcursor} generates {enter}k
Pressing {rightcursor} generates {rightcursor}l (letter el)
Pressing l (letter el) generates {rightcursor}l (letter el)
 
If an external usb keyboard is plugged in all keys are displayed correctly.
 
Running Windows 7 (x64).
All regional settings are set correctly.
The keyboard item was removed in device manager and reinstalled. No change.
Full antivirus scan was completed with no problems reported.
Using the keycodes.exe utility confirms the incorrect, multiple scan codes are being generated.
 
Children use this system. Is it possible the keyboard mappings could have been accidently changed?
 
Any assistence would be appreciated.
 
Thanks.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It's possible. One thing you could do to check would be to plug in an external USB keyboard, and see whether the problem goes away with that keyboard. If it does, your keyboard is damaged. If it doesn't (i.e. the problem continues even with the external keyboard), it's probably a setting somewhere.

Please note - I did indicate in the question that an external keyboard does work properly.

Sorry - missed that. Then I think your keyboard is probably damaged.

Just curious why you awarded the points to ve3ofa, when I answered your question first? Nothing against ve3ofa - but that doesn't make sense to me.

Whatever... what's done is done.

Oops, that wasn't my intent. I had intended to award you the points.

How can I correct that?

I requested the moderator change the assignment of points. They should have gone to d0ughb0y.
