You're very welcome, Peppe.
Could you please confirm that you've visited the Dell driver site, either entered your Service Tag# or auto-detected your device and then downloaded and installed all the recommended updates?
From your screenshot posted earlier, showing MS drivers for your PS-2 Keyboard, these are default Windows drivers, not from Dell.
The only reason I'd be expecting to find keyboard drivers from Dell is that you said you were able to wake from keyboard in the past. Chances are, in the past your wake from keyboard was available because you had other drivers from Dell.
Also, could you please confirm which OS was installed when the wake from keyboard was successful, was it 8.1 or which version of Windows 10?
