Okay, after I installed Windows 8 on my Sony model VPCEH27FD laptop, my FN keys don’t function. I’ve consult Sony expertise, and they provided me some half-ty answer that doesn’t work at all! (madness)! Fortunately, there are smart Sony “user” on the internet that posted a solution in the community. Basically, what you’ll want to do is the following:
- Find your Sony model at their website: Here
- Go to Driver & Software tab, Select Windows 8 64-bit in the drop down box, and click Open File List
- Download the following drivers and install them IN ORDER:
a) Sony® Shared Library
b) VAIO® Control Center Software
c) VAIO® Control Center Update
The FN keys should work after your computer is rebooted!
