those functional keys in sony vaio work by the operating system you get when you buy the laptop.

As you've changed to windows 8 they are not working.

So now what you do is, if want those keys to work, install the windows 7 operating system you got from sony and upgrade it to windows 8.

Then they would work fine.

Thank You.
