T420s fn key screen brightness controls not working

Fn-Home and Fn-End no longer adjust the screen brightness of my laptop.  The home and end keys alone work fine, as do other function keys.  A suggested solution on another thread was to roll back the video driver - I tried this and lost the video driver altogether, and had to reinstall it manually.  (This may be because I recently had to restore the system to a two-year-old image as a result of another problem, which was apparently caused by updating to Windows 10 and then reverting back to Windows 7).  The video driver (Intel(R) HD Graphics 3000) is up to date.  I am running Windows 7 64-bit edition.  Any idea what could be causing this?

Thanks!
