Hello,
i own a HP ProBook 470 G4. Unfortunately the Brightness-Hotkeys arent working after a fresh Windows 10 64 Bit (All Updates are installed) installation. I`ve already downloaded the Hotkeys-Driver from the Download-Page. Googling this problem results in the following thread with the same problem:
The TO in this thread is happy for the download link https://ftp.hp.com/pub/softpaq/sp81501-82000/sp81790.exe and means "It works like a charme".
The Downloadlink isnt valid annymore. 😞
Can someboby help me by providing a working link to sp81790.exe or another solution?
Thanks
Kind regards,
Barb
