Solved: F3 and F4 brightness keys stopped working - HP Support Community

Mari__ · ‎12-19-2021

Suddenly (beginning of Dezember 2021) the brightness keys F3 F4 did not work anymore. Others as F5, F6 F7 (Loudness), F10 e.g. work as before. Restarting the Computer did not help. Windows Version 10.0.19043 Build 19043. Maybe in the background, there has been some updates, which I did not realize.

How can I fix trhat? THX for helping me.

Hello @Mari__ .
Update the bios of your computer:
https://ftp.hp.com/pub/softpaq/sp136001-136500/sp136460.exe

Updating the bios improves performance, solves specific problems, adds security patches and may be that the current BIOS is not compatible with a hardware component or a Windows update.
1. Download the file by clicking on the link I provided and save the file in a folder on your hard drive (make a note of the folder where the downloaded file is saved).
2. Double-click on the downloaded file and follow the on-screen instructions.
Note: When updating the bios, do not turn off the computer, do not suspend and in the case of laptops do not put the lid down, and keep your computer plugged directly into a power outlet.

Download and install the following drivers:

https://ftp.hp.com/pub/softpaq/sp103501-104000/sp103615.exe
https://ftp.hp.com/pub/softpaq/sp98501-99000/sp98968.exe

Finally, restart the computer and check if the problem has been solved.
