I bought a T480s back in December 2018 and have noticed this problem in the title for quite a while now. I'm running the following:
Multiple times throughout the day my screen will flicker or momentarily black out sections (typically the bottom portion) of it. It doesn't happen as often when fewer applications are open, but it still occurs even then. It doesn't appear to be a hardware issue, given that I've tried moving the laptop back and forth, shook it gently etc. to try to reproduce the strange behavior.
I tried updating the Intel drivers only for the problem to worsen -- updating the driver to the November version (25.x something) caused the computer to additionally black out the screen entirely at times, which could only be resolved by putting the laptop to sleep and waking it up again!
I've decided to install version 220.127.116.1123 of the Intel 620 UHD driver, and I'm hoping it works without a hitch, but has anyone else had and resolved this sort of issue before?
Or if some Lenovo staff are around, is there a solution?
I'd really like to send it back for a replacement but my schedule won't allow me and I'd be out of a laptop for work.
Solved! Go to Solution.

In the Intel Graphics Control Panel, disable Panel Self-Refresh for plugged in and Battery also.. There are 2 sections to change. This fixed it for me.
