hi cadillac59,


Welcome to the Forums.


Your problem might be similar to this thread.


Can you try the following:

1. Set the power plan to High Performance

2. Follow this guide on how to disable Adaptive Brightness

3. Update the display driver to the latest.


If you have the B50-30, B50-70, or B50-80 then try installing this driver or a higher.version

Re: Lenovo B50 - Screen goes white and flashes.

i have the same issue with my B50-30, and sent it to technical service twice. Both times they said it was the flex wire, and both times had to replace it. But it keeps getting broken only within a month of regular use. My question is: how do Lenovo fix this hardware factory failure? cos apparently it has no actual solution
