Problems with FN Keys


New Member
Hello guys. I'm new here.
I have problem with my Sony Vaio VPCEH3M1E FN keys.
On Win7 it works perfectly but when i upgrade to 8.1, my FN keys stopped working.
I can only use FN keys for mute, volume and NumLK / ScrLK.
What about brightness and Display change (Expand to second monitor etc.)?

BTW. Sorry for my bad english :X

Check and see if there are any newer drivers for your computer.
I see a lot of people are reporting the same issue with a lot of different computers.

See if there is anything in here...

Yes FN keys arn't part of Windows but the motherboard or keyboard drivers
