Vertical lines on screen and cannot change the screen brightness

HP Recommended
HP 15-db1904ng
Microsoft Windows 10 (64-bit)

I bought a hp 15-db1904ng notebook new last month and yesterday a single thin, horizontal, line showed up across the screen. While I was trying to figure out the cause of it today the line suddenly vanished but now I am unable to change the screen brightness in any way. Not with the keys, nor if I go into the settings and try to change it from there. The slider moves but the brightness stays the same. The notebook also now takes quite a while to properly shut down. Is there any way that might fix this or do I have to send it in for repair?

I reviewed your post and I understand that you are unable to change the screen brightness.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I recommend you update the BIOS and the graphics driver from the below link and check if it helps.

 

BIOS: https://ftp.hp.com/pub/softpaq/sp106001-106500/sp106084.exe

 

AMD: https://ftp.hp.com/pub/softpaq/sp107001-107500/sp107276.exe

 

Let me know how it goes and you have a great day!

Thank you for the solution, however the fact that I cannot change the brightness fixed itself at some point so I did not test your solutions, however now I have different troubles. The notbeook takes up to a minute to shut down and, when I play a video on any website the video itself will sometimes turn out in a bright green. It gets fixed when I play the video so it doesn't bother me as much as the notebook needing so long to shut down does.

Any solutions for that?
