Latitude E6430 ...a little help from Italy ...

Hello to all. I'm Max and I'm writing to you from Sanremo (Ligury - ITALY).

I've just bought a Latitude E6430 used, which was installed Windows 10 PRO (v.1709)

Configuration: 8Gb RAM - Intel Graphics 4000 - Intel quadcore i5 (2,70Ghz) - HDD 320Gb

I cannot configure the three keys below the space bar and (even) the fingerprint sensor.

This laptop it was originally purchased in France.

Best wishes, I'm in stand by for your kind answers.

P.S.: Excuse me ...for my not perfect English!
