Hi jamnelso35,

The following is copied from Vaio Support. In your case it will probably be step three that needs to be followed.

Special keys / hotkeys / Fn keys do not function

Most VAIO computers have a few additional special function keys, which are not controlled by the standard keyboard driver.

If these keys stop functioning, this is usually a problem related to VAIO Event Service.

Step 1:  click the Start button, type Services.msc  and press Enter.
In the list of services, locate VAIO Event Service and verify that the service is started, and startup type is set to Automatic.

Step 2:  if step 1 did not solve it, or you could not locate VAIO Event Service in the list, you may need to reinstall VAIO Event Service.
This can be done through Start - VAIO Recovery Center -  Reinstall Programs and Drivers.
If this option is not available, VAIO Event Service can also be downloaded from the Original Drivers section.

Step 3: in some cases, some additional related utilities also need to be reinstalled, in the same way as Step 2.  These are:

• Setting Utility Series
• Sony Shared Library
• VAIO Event Service
• VAIO Control Center
• Also, if you have installed      your own OS, the SFEP driver needs to be correctly installed in Device      Manager for some models.  If applicable, you will find this driver in      the Original Drivers section.
