Legion Y540-17 screen blacks out and flicker after windows update on July 2021

2021-07-09, 14:30 PM

Hi,

 

After the recent unwanted automatic update of the bizarre windows 10 I lost control of screen blacking out and flickering randomly.

External monitors work fine!

Displace diagnostic from Lenovo advanced diagnostic tool pass!

Graphic card diagnostic from lenovo also pass!

The NVIDIA gtx 1660 ti driver was updated with the bizarre windows update . I rolled it back to the previous version but it didn't help.

I cannot roll back the whole windows update since it has passed 10 days.

 

Any solution anyone?

 

a simple windows update mess up a $1000 plus laptop. I never had this issue with any cheaper laptops I had.

Hello @soriM,

 

Welcome to the Community Forums.

 

Kindly uninstall the display drivers of the machine and download the ones available in the support site.

You can download it using this link (please note that you may have to enter your serial number in order to get the right file):  https://pcsupport.lenovo.com/uk/en/products/laptops-and-netbooks/legion-series/legion-y540-17irh/downloads/driver-list/component?name=Graphics%20Processing%20Units%20%28GPU%29%20and%20Server-AI%20Accelerators


Hope this helps.

Hello Jack,

 

Thanks for your help.

I followed your instructions. uninstalled the graphic drivers from nVidea and reinstalled the one provided by Lenovo.

It helped with the screen blacking out which was getting worse and worse by minutes.

However, it has not helped with the random screen flicker.

Do you have any more suggestion to save me this $1000+ laptop?

Hi,

 

Has anyone has any idea to fix the issue?

 

My screen still flickers.

The graphic driver is the original one from Lenovo website.

 

It is interesting that the flicker does not happen on external monitors when connected.
