Solved!

HP ProBook 440 G5 brightness key is not working

HP Recommended
HP ProBook 440 G5
Microsoft Windows 10 (64-bit)

Hi,

I bought this brand new HP ProBook 440 G5, Everything seemed nice and working well until I run the HP support Assistant started giving me notifications about some drivers that require updating. I did update the drivers and I lost the functionality of the brightness keys. 

searched for similar posts and found one 

https://h30434.www3.hp.com/t5/Business-Notebooks/HP-probook-450-G4-fn-bightness-keys-not-working-win...

 

I went to my HP driver site and downloaded the driver, tried to install it but it shows me that the present driver is newer than the one I am trying to install.

 

Please help as this is really annoying.

Hello,

Thank you Di-Mass for the  solution!

I installed CCleaner:

https://www.ccleaner.com/ccleaner/download/standard

And went trough Tools-Uninstall and searched hotkeys and uninstalled the tool.

Then, installed the tool from HP for my laptop:

After the restart, it worked

I am dealing with the exact same issue. Brithness keys are not working on HP 440 G5. I cannot install the hotkey driver obtained from the hp webpage as it says a new version is already installed.  

please let us know if you have experienced the same issue, or if you know the solution.

Hello,

 

440 G5 and I have installed all latest win10 updates. after that Fn-Brightness doesnot work / Fn-Sound - works well. 

I tryed to install sp81790 (HotKey Support) but system every time says that It is already installed - and that is really weird!

No option to remove this HotKey  support but I used CCleaner, Remove (!!!) HotKey Support, reboot, install again with success HP_Hot_Key_Support sw package and Bingo! I can use Fn-F3/F4 and Fn-F1.

 

Cheers,

Dimi

My brightness keys (the stars on the upper left row of the keyboard) fell out a few months ago. I presume after a windows update. From then I regulated brightness by clicking on the battery icon... That works well in four steps (25-100% brightness). And from today: The keys work as always! Do not know if it was the BIOS update or a new windows update.

The URL for the driver did not work. However, the procedure is ok and I was able to search for the driver on HP's website and downloaded it. And it worked,

Thanks
