I reformatted the laptop after installing a new hard drive in my Sony Vaio and now it isn't letting me use the brightness function keys anymore. The function volume keys still work, it's just the brightness ones that aren't going very well. Is there a software requirement or something I'm missing?

For these buttons to work it requires Sony's proprietary software. Luckily, the packages required t operate the Brightness buttons isn't bloated like their Vaio Care crapware.
To set it up, visit http://esupport.sony.com/US/p/select-system.pl?DIRECTOR=DRIVER and type in your model number. On a Vaio this should be found below the bottom-right corner of the screen.
Once on the model's support page, download the following:
Be sure to also install any updates available for those services..
Now once you finish installing all of those your brightness keys should work. You might run into an error window that tells you "the installed battery may not be properly connected." This isn't an error to be worrieed about, it's just a false alarm. To disable it browse to C:/Program Files (x86)/Sony/ and delete the ISB Utility folder.
