I noticed this on my new P52 ThinkPad laptop and I though the problem was Lenovo's but you are seeing this also, then this is a more generic Windows problem.

I have the same issue that I set my brightness to a specific level and when I reboot, the brightness is down to a fixed level.

Has anyone else seen this problem on a laptop ?

I have seen a number of comments around about the internet re the brightness being lowered to 50% on re-starts following installing 1809. My computers are HP & Gigabyte and it happens on all four. Supposedly they all have the latest drivers.

had fun installing this.
as it didnt want to install.
kept failing at 38% on reboot. then rebooted and rolled back to it tried again and again about 4 times and then it went to the login screen.
tried about 3 time and same thing every time.
then I ran sfc and some dism commands and download the update from windows catalog and ran it. and it finally installed.
about 3 hours wasted

Loaded onto laptop and pc both did not load first time when they had loaded had trouble restarting with message cannot find settings then bsod now running okay also since the problem with 1809 made public we have had telephone calls at least four times a day from so called Microsoft engineers saying that they will fix the problem it did not take long for scammers to find another way to take peoples money

To get round the 50% brightness problem you can try this - Intel Graphics Control Panel/Graphics Properties/Power/On Battery/disable the 'Display Power Saving Technology'.

Also, ensure that automatic battery saver in Settings/System/Battery is unchecked and that 'Lower screen brightness while in battery saver' is unchecked.

I downloaded the KB4464330 from the link given on page 1, installed, and did not get the "initial fail/then installed" issue many here have reported. Also, on the initial 1809 update, I did not suffer the documents loss.

Thanks. The problem is that this problem happens even when plugged in.

My downloading it fails for the last ten times

I've also noticed I can no longer turn off firewall notifications. I don't use it, it's disabled and I used to be able to turn the notifications off. Now, even though they are off they still make the notifications to my action center.
