I have a Lenovo Ideapad 530s Laptop. It purchased it in May 2018, and have been using it without any problems until today morning.
I have just moved to Japan from Korea (where I bought my laptop). It was working fine until yesterday night when I noticed that my screen would flash black - momentarily, but enough to stress my eyes out.
When I disabled Intel UHD Graphics 620 from Device Manager, the flickering stops. I did a clean install of Windows, but that still didn't fix the problem. I updated my drivers to the newest ones put out by Intel, but still no fix. I disabled Virtualization in BIOS. I have turned off Lenovo Powersaving. I ran Lenovo Diagnostic tools on it, but everything shows up to be fine.
I think the problem has to be with the Intel Graphics (hardware and/or software).
Please Help!!! Any help is appreciated!!
