Please report the brightness and overheating to Microsoft using the Feedback Hub. The sooner they are aware the better. Once reported, other users with the same issue can upvote it.

Re: Yoga 920 Windows 10 1809 Update: Screen Brightness not working after sleep [BUG]

Hi everyone,

 

I was having the issue as well but fixed it through Lenovo Vantage. 

 

Open Lenovo Vantage from the Start Menu.

Go to System Update, Check for Drivers, and there should be 3 drivers from Intel.

Update, install, and reboot.

Fixed!

 

Hope it works for everyone.

The same goes for the Yoga 930, No available drivers through Lenovo Vantage.  Luckily I can still return this unit through January if this sin't corrected.

Re: Yoga 920 Windows 10 1809 Update: Screen Brightness not working after sleep [BUG]

On the yoga 920, running Win10 1803, I tried today to update to 1809 with no luck :

-Upgraded graphic drivers to Intel 25.20.100.6471, from the .exe on the Intel site (not available on the Lenovo site)

-Clicked on Windows 10 check updates button.

-No 1809 available.

 

So the Microsoft 1809 re-release seems to be still blocked, at least , even after the second driver update of the Intel GFX drivers, which should solve the 2nd audio driver issue, as well as introducing the new Windows Modern driver mechanism.

 

Even though, latest informations from both Microsoft, Intel and Lenovo does not permit to know what kind of block is still applying.

https://support.microsoft.com/en-us/help/4464619

https://www.intel.com/content/www/us/en/support/articles/000031275/graphics-drivers.html

https://support.lenovo.com/us/fr/solutions/ht507291

 

So seems like today the 1809 is still a release limited to selected users.

Finally,

after ensuring latest graphic, wifi drivers, I updated with the help of the Windows 10 install assistant, below.

one month with 1809 with no issues, Smiley Wink !!

Issue is fixed with the official Lenovo Intel graphics drivers and the most recent Winows 10 release candidate of the April 2019 update.
