Thanks for your support.

My issue is that both DISABLE and ENABLE BIOS options lead to the same result, i.e. I need to press Fn key to access the Fn action of the function keys. Example to get F2 I need to press the Fn key, and I'd like to get F2 without pressing Fn key.

This BIOS toggle  used to work in the past.
But one day, when booting I had a msg about this BIOS option, but I did not took care and forgot the precise description of the message. Since then I have the issue described above, i.e. inoperation of the BIOS toggle between ENABLE and DISABLE.

Your help is appreciated.

My laptop is 15-cs3159nb Prod id 2E6Y8EA#UUG  sn  5CDO365Y4Y
