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

2018-10-03, 21:19 PM

As the title suggests, after updating today to the latest version of Windows 10 (October Update, 1809), I cannot change the brightness levels after waking the computer from sleep. The brightness remains constant. Only a restart fixes the problem.

 

Laptop: Yoga 920 Glass i7, 16GB/512GB

How did you get the update? I just don't get it to update with the windows update function. It just doesn't appear even after updating the intel graphics drivers as recommended by Lenovo.

Hi mgymnop!

 

 

 

Thanks for posting in our community. 

 

 

 

You may download and install our Lenovo Vantage tool in this link https://www.microsoft.com/en-us/p/lenovo-vantage/9wzdncrfj4mv#activetab=pivot:overviewtab from there, go to driver update and then install all the updats that will show up. 

 

 

 

Thanks.

Hi drhannibal!

 

Welcome to the Lenovo Community Forums!

 

Let's try rolling back the display driver. Please follow these steps:

 

Press Windows key + X
Click Device Manager
Expand Display adapters
Right click the current display adapter
Click Properties
Click Driver tab
Click the Rollback driver if the option is available

 

If the rollback is not an option (grayed out),

 

Right click the current display adapter
Click Uninstall
Check the box that says, "Delete the driver software for this device.”
Exit Device Manager
Restart

Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.

 

Or, use the Lenovo Vantage https://support.lenovo.com/in/en/solutions/ht505081, and run the System Update. Let us know how things go.

Maru,

 

I managed to fix it by downloading the latest Intel drivers. For your information, Lenovo Vantage showed no available updates, so maybe Lenovo should issue new drivers for this update.

 

Mgymnop,

 

The update just showed up on Windows Update. However, you can also download it using the Media Creation Tool directly from Microsoft.

We would like to find out if this will do the same thing when using the Microsoft Basic Display adapter, to see if this is even related to the Display adapter. We would have to uninstall and delete the driver through this steps: https://docs.microsoft.com/en-us/windows-hardware/drivers/install/using-device-manager-to-uninstall-devices-and-driver-packages?linkId=57888519 . Once removed from Device Manager, click on "Action", then select "Scan For Hardware changes". This should somehow install a Microsoft basic driver. Check if the issue would still occur. 

To download the Intel Graphics Driver, simply download from our site: https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/YOGA-SERIES/YOGA-920-13IKB/downloads/DS500703?Source=social_eservices&Medium=LITHIUM&Term=eServices_&Content=20181008_20181008165539&linkId=57888520

I reverted to the last windows build 1803. It is working better. Waiting the final solution.. I also noticed when I was on 1809 that the notebook was overheated.. now on 1803 build it is normal..

My yoga 920's screen brightness is not working after sleep or when the laptop is in an ideal state for too long. The only solution is to uninstall and then reinstall the driver. Need some permanent fix for this at the earliest.

I'm experiencing the same issue. Most of the time I am unable to adjust brightness after ugrading to October 2018 Update. Reinstalling the driver temporarily fixes the issue but then it usually happens again after another sleep/resume cycle. There are no available updates in Lenovo Vantage - I keep checking often.
