Good day,
I have laptop ProBook 4540s with Windows 10. It was big fight to change from Windows 7 to 10 because of the drivers. After few hours which i spent to fix the bluetooth and laptop camera, now i am facing ne problems. Fn did not work with all buttons. Finally i found drivers sp71790 and all buttons are working except one. Laptop did not respond to F1 (Half moon, sleeping mode) + FN. Only this combination is not working. Do you have any suggestions?
