Product: HP ProBook 470 G4
Operating System: Microsoft Windows 10 (64-bit)

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:

 

https://h30434.www3.hp.com/t5/Business-Notebooks/HP-probook-470-G4-fn-bightness-keys-not-working-win...

 

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
