I purchased a T420 a few months back and two times (just before cleaning the screen with a dry fiber cloth) I've noticed what looks marks made by the keyboard (vertical lines, spaced approximately as the keys) and what looks like marks made by the touchpad (small dots, the touchpad is dotted) on the screen.
The marks disappear when cleaning the screen with the fiber cloth which is good so far, but I fear it is the dreaded phenomenon of the keyboard scratching into the screen because the screen touches the keys when the lid is closed. Back in the days and with cheap laptops you see permanent damage to the screen from this.
Have any of you guys experienced this with your T410, T420 ect?
Should I place a fiber cloth between the keyboard and screen when I close the laptop?
It seems silly that Lenovo got this one thing wrong with this laptop..
As soon as I see the marks again I will make sure to photograph them and show the pictues here.

I have not had any such issues with my T420 (or T400). I would think if it is leaving marks on the screen that there is an issue with the way the machine was put together.

Could it have to do with the fact that I replaced the US keyboard with a danish keyboard? Original Lenovo spare part (customer replacable part) of course. Would be stupid if some of the keyboards were thicker than others, so I guess not... but on the other hand a qualified Lenovo could do a better job than I... but then again it has to click into a few specified holes/pins and one screw has to fit in, so it doesn't leave room for much choice when installing.

I would not place anything between the keys/touchpad & the screen as this would be construed as
foreign to the design, hence no warranty.
Did you have this problem before you replaced the keyboard? If not, the problem lies in the the new
keyboard, the instalation thereof, or both. (IMHO)
