Clean install troubles

[glazexd]

Changed my hdd to ssd on my sony vaio vpcf23jfx and did a clean install to windows 10 now my fn brightness toggle, vaia backlight key, vaio power management and disable trackpad fn has ceased to operate.
Any help on my situation?

Go the Sony Vaio product page for your model and download/install the model specific keyboard drivers or utility. If there is not a Windows 10 specific version available there, try the windows 8.1 version or you may have to wait until they release suitable drivers/utility for the hotkey functions.
