Lenovo Yoga C930: Screen flickering

Hi,

 

after purchasing my Lenovo Yoga C930 in November 2018 it worked completely fine until 4 days ago. At some point, I started noticing some slight flickers in the form of very thin lines that would span over the whole screen width. I then updated the Graphics Card drivers which solved the problem for two days, then it came back. Since yesterday, there are now some hug screen flickers (similar to this, but a bit less bad: https://www.youtube.com/watch?v=6SIHJYWsFCI ), which are increased if the laptop is on battery mode as opposed to when it is plugged in. I tried to see if there was a difference between the different power modes in battery mode, but it doesn't seem to be the case.

All the drivers are up-to-date and I am very dependent on my computer for work, so I would rather not send it in if I can avoid it in any way. Has anyone had this issue with a C930 and managed to get rid of it?

 

System information:

Windows 10

Intel(R) Core(TM) i7-8550U CPU @1.8GHz 1.00GHz

16GB of RAM

 

Thanks in advance for useful feedback!

Cheers,

Julia

Re: Lenovo Yoga C930: Screen flickering

I have now really tried everything

- Updated BIOS

- Updated all possible and imaginable drivers

Did not help.

Reset the computer

- First it was worse, then it got better with updates, but the problem persists.

 

I have to send it in now. It's just incredible that Lenovo cannot solve this problem and drags it from Laptop generation to Laptop generation. Especially for a machine that I paid 2100 Dollars.......

Does it happen when you use the NOVO menu (Start computer with Fn + Power, I believe) and navigate to the BIOS settings screen? Do that without booting Windows and see if it flickers.

Hi!

Thank you very much for your reply!
Yes, I have tried this, and it never happened when seeing the NOVO menu. So in that sense it seems that it might be Windows-related, but since I reset the computer and it still happens I am not sure anyway. the flickering also almost never happens when the computer is "freshly started", but only after a certain time that it's on and mostly after it has gone to sleep and is turned on again. A restart usually fixes it for some time. 

 

Best,

Julia

If you see it in the BIOS windows, it's hardware. Needs to be sent in, I'm afraid.
