Windows 10 brightness not working. If the problem started after install windows 10 version 2004, them make sure you have installed the latest Cumulative Update, As Microsoft mention: 'Addresses an issue with the brightness controls on some laptops after updating to the Windows 10 May 2020 Update. Many modern laptops and tablets have an ambient brightness sensor, which works similarly to the one found on smartphones and tablets. Windows can use the sensor for ' adaptive brightness,' automatically increasing your display brightness when you're in a bright area, and decreasing the brightness when you're in a dark room. Laptops and PCs are mostly indoor creatures, so they don't need to be as bright. 200 is on the low end but still usable, while above 400 is above average. Not many computer displays go above 500 or 600 nits, and you probably won't need to use the full brightness on one of those very often. One problem I have with it is the screen brightness; it isn't very bright. I have it set to maximum brightness (checked using both the Control Panel and fn-f6). I also own an Asus UX21 ultrabook and, putting them side by side, the difference is noticeable. The UX21 is super bright and the Trio is far from it.

Other laptops have keys dedicated entirely to brightness control. On the HP Chromebook keyboard (pictured below), there is no Fn key — press the brightness keys.

If this is the case, you'll need to create a custom power plan, which can be done by accessing the Power Options utility in the Control Panel.
Driver issues
If the key combination method is not working and you've made the appropriate adjustments in Power Options, it is likely your computer has a video driver problem. Driver issues usually occur after updating the video drivers. Monitor drivers can also cause this problem. To resolve any potential monitor related issues, reinstall the monitor by following the steps below.

Finally, we also recommend downloading the latest video drivers directly from the video card manufacturer. If this problem was caused because you updated the drivers, install an earlier version of the video drivers to see if that resolves the issue.
Laptop brightness is still not enough or screen is black
