Thinkpad T480: Any idea what’s up with the screen?
Just bought a T480 from Marketplace. Any idea what’s up with the screen? Look closely. There’s some weird banding.
not really no, it is to be expected through a machines life, usually putting it in a laptop case with the power supply is sufficient to do this over a period of time
Thats the backlight diffusion being disrupted by pressure or liquid, not too bad per se but since u can see it id swap the panel, is easily done on those things.
I didn't notice the anomalies. But the white screen shows them best. I've seen this on countless laptops and as says, these are pressure marks. Or just daily wear and tear. Is your LCD in such a bad shape during normal operation that this bothers you?
it's in self test diagnostic mode or something like that. i've seen this issue in another group or subreddit answered so do check... i believe you can make it running again by restarting your pc in a specific way.
