Original Question and Answer
Sorry to re-open an old thread but having just re-installed the Vista Home Premium OS on a Vostro 1510 I am having this exact keyboard 'last row keys' issue (see above link)
However when I download the file mentioned in the 2nd last post (the generally accepted solution and the one promoted for Dell Tech Support) and run it I get a dialog with the following error "SCM OPEN FAIL". Therefore the solution does not work for me.
I've googled this error message and can't seem to find any reference to it. Any help appreciated.
