Hi @vtzivaras,

Assuming that the SFEP driver is installed and recognised in Device Manager, try installing Sony Shared Library followed by Sony Notebook Utilities.

Hi there, thank you for aSnswering. How can i be sure that SFEP driver was recognized and it is working? 😕 Ok i did that but still there is no function in Fn keys that control brighness. Notice that Fn keys that control Volume are working. Also at the control panel there is no blighness settings. Any ideas? 😕

 Hi @vtzivaras,

If Sony Firmware Extension Parser Device has installed you will find it listed in Device Manager under Human Interface Devices.

If there are still problems then we will need further details of the operating system and any upgrades.

Reinstalling Sony Shared Library and Sony Notebook Utilities usually solves the problem you have with Fn key brightness issues but without the details I requested regarding OS - original or clean install/upgraded it is difficult to advise further.

You could try uninstalling Vaio Event Service from within Control Panel - Programmes and features and then reinstall Sony Shared Library and Sony Notebook Utilities. If you have carried out a clean install of the OS then it may be necessary to install all drivers and utilities available for your model on the support site.
