    Laptop randomly became super laggy and now can’t change brightness


    I was on my laptop yesterday and everything was running fine. My laptop is normally slow and games can be a bit laggy, but still bearable. Randomly, it restarted and ever since that, games have been extremely laggy. It lags and glitches in the main menu. I cant even play games anymore due it turning super laggy out of no where. Additionally, i can no longer change the brightness of my laptop. There’s no way i can change it now. I went on settings and the brightness settings vanished.
    Super confused with what happened to my laptop.

    :)

    Unable to Change Screen Brightness of Laptop


    So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
    - Reinstalling Display Drivers
    - Rolling Back Display Drivers
    - Reset Settings on UWT4
    - Power and Battery Settings
    (UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

    If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -
