Ever since I updated to BIOS 1.11, I've intermittently had the screen-flickering-lines issue (interestingly, haven't had it before then). I've been trying narrow down a predictable way to reproduce the issue, but so far I've sort of failed.
Usually, the issue comes up after the X120e is left idle for some time, with maximized applications open. The flickering seems to occur only in maximized applications, and stops once the window is restored. However, if it is maximized again, the flickering continues.
The flickering also seems to decrease with time--when it starts, there are initially many lines and near-continuous flickering. Then, the rate decreases until it seems to go away on its own accord.
A reboot fixes the issue.

I had a momentary screen flickering issue.
It was very specific though... Whenever I brought up the hotkey overlay (like brightness control or volume) the right hand side of the screen flickered while the overlay was up. But this only happened on a few webpages... when I opened a new tab or went to a different tab, the issue disappeared. Issue reappeared though when I switched the browser back to the page that exhibited the flickering. Browser was IE9, and now I can't recreate the flickering.
Feels very random.

I can confirm, after going through 2 X120e laptops, updating the bios, not adding any additional RAM, etc... the issue still exists.
Thanks for the update. This makes me think it's some driver/firmware issue and not hardware .
For those that have the flickering issue, could you try running something GPU intensive (like playing a flash video) to see if it makes the flickering stop when it's occurring?

Thanks for checking in, James.
1.- Yes: as I mentioned, the issue only occurred after updating to 1.11, although that could possibly be coincidental.
2.- Yes: I removed the 2GB stick of DDR3 1066MHz RAM I installed (Lenovo-branded; Samsung chips), but encountered the flickering issue again the day after.
3.- Yes: I reseated both sticks after the experiment in #2.
4.- Yes: I have all W7 updates including SP1, and have pretty much all the latest Lenovo drivers as well.
