I have two toshiba portege r500 which have never really be used since purchase about 2 years ago.
Today I get one out to start using it and find the ctrl key is not working which I thought was strange.
After a little browsing I could not find a solution so I simply got the other identical laptop out and starting using that only to find the exact some problem.
The laptops are both running XP.
One of which I have reformatted and uninstalled the keyboard driver to see if that would solve the problem but it did not.
Any others. Many have suggested that it may be due to a damaged keyboard cable but I think it would be highly unlikely that they would both break in the same way.
