I have made a clean install on a Sony Vaio laptop (VPCF22L1E/B), which originally had Windows 7. After installing the drivers for Windows 8 that Sony has provided, I realized that the fn + f# keys did not work.
So I searched the internet for a possible solution. I've read that I need a driver called Sony Vaio Event service, which is available for Windows 7, but not Windows 8. I tried installing the Windows 7 driver in compatibility mode, but it didn't work. Is there any workaround I can try?
