Welcome to HP Forums,

I recommend you check if any buttons within the keyboard are physically stuck, if they are this could be a hardware malfunction and if they aren't stuck as such and yet the issue persists, it's merely a software issue and here's what you'll need to do:

Start with updating the video card, BIOS & Chipset driver update using the HP website: Click here to find and install the same.

Also, ensure the automatic brightness is turned off, using the below steps:

1. Open the Windows start menu and click on ‘Settings’ (a cog icon)
2. 
3. In the settings window, click on ‘System’
4. 
5. The ‘Display’ menu should be selected on the left, if it is not – click on ‘Display’
6. Turn the ‘Change brightness automatically when lighting changes’ to ‘Off’
7. 
8. Click ‘Apply’ to save the changes.
