Why does my screen brightness buttons are not working?
The F2 and F3 key assigned to regulate brightness is not working.

Some laptops require you to hold down the FN button on your keyboard to use the functions assigned to those keys, like brightness. Try holding down FN while pressing F2 or F3.

Nope I know that part but it doesn't require fn key as earlier both keys were working properly and I was able to manage brightness. But I still tried holding Fn key it didn't work unfortunately. Thanks for answering tho.
Hmmmmmm... Could you maybe check that FN lock wasn't accidentally turned on? I don't recall the exact keyboard shortcut so I can't be more help than that, unfortunately.
