hello , Yesterday I installed the 1809 update , and today i noticed that each time i restart my laptop the brightness level is being reset automatically to 0% or 25-50 i'm not really sure , and after windows will boot up , i will need to manually adjust the screen brightness again to 100% . I searched the web and i found this https://www.windowscentral.com/windows-10-october-2018-update-common-problems-and-fixes#fix\_brightness\_windows10\_1809 , and it might be an update issue i think  , by the way , my power plan is set to maximum performance and my laptop is always plugged in , and solutions or ?

    I kind of had a similar problem where Is  was unable to change the screen brightness, wether i increase or decrease the brightness it stays unchanged , but i was able to solve it by updating my display adapter driver so try checking display adapter drivers updates from Driver Manager if available do the update and check 

    Hope this might be helpful !!

    I think most of us have tried everything but still a windows issue. I updated everything on my surface go and on my Asus laptop and still the issues. 

    The only way to (somewhat) fix the issues: powercfg /h off    (hibernation off). That "caches" some data and when you (fast) boot it produces issues. Disabling it forces full (and slower) boot and fewer problems. 

    After almost 4 years (I had similar issues with other PCs back on windows 8.1 and on Windows 10 first versions) later,  and on a desktop (3 year old), Asus laptop (8 months old) and on a Surface Go (2 months old) I have identical issues with windows. Embarrassment...

    I have the same problem, my screen is so dim even at full brightness it is impossible to work in the day time. I have removed this piece of junk and went back 1803.

    I have a similar issue on a Dell XPS 13 9360 that we have at home.

    After the 1809 version was installed in October, the display brightness remained stuck at 50%.  After the Nov Cumulative Update, the brightness could be adjusted but a new issue popped up as follows:

    • If the laptop works on battery for a long time, then the display brightness remains again stuck to 50%: plugging to the AC power outlet does allow the brightness to increase. The only remedy I found out  is  to shutdown and re-start the laptop with a new start, then the brightness control works nominally again.
