I saw the other thread about the flickering with lines across the screen. I have a similar but probably different problem. My whole screen flickers like a dying fluorescent bulb at low brightness. I have been able to consistently reproduce from the first time I booted up. Updated display drivers, disabled PowerPlay, tried various power profiles, tried on AC and battery - nothing had any effect. This very much looks like a hardware problem. Anybody else seeing this or is my screen just defective?

If you go into the BIOS (just start hitting enter when you turn on the computer), do you see the flicker there? If so, it sounds like a hardware problem.
How low does the brightness have to be to see the flicker? Just anything below max or do you have to get down to 1 or 2?
If not, it could be the "Varibright" setting in the video driver, though that just changes the backlight depending on what's on your screen, so it's more of a slow change in brightness (I know you said you disabled powerplay, but I'm not sure if you disabled varibright).

Did a replacement fix your issue poster? I just bought my machine and I am not sure if this is something just some people notice, and that is how it is made. I have never seen anything like this flickering before and I normally go with lower end laptops. My x120e is actually replacing a Lenovo ideapad s10-1 that cost 199$, it's screen is perfect (as far as clarity goes).
I opened another thread not seeing this one...

I haven't had time to get it RMA'd yet. I'll have to get it done soon as the problem seems to be getting worse and happening at higher brightness levels now. I saw a post on another forum with the same issue - he got it replaced and that took care of it.
From what I've read, there are two panels used in the x120s, an LG and a Samsung. I'm hoping they use the samsungs as replacements as they are supposedly a bit less terrible in terms of color / contrast / viewing angles.

Got my x120 back from RMA. Inexplicably they replaced the LCD cable, listing the symptom as "cannot adjust contrast." I have no idea where they got that from. The paperwork doesn't mention that the issue I sent it in for was even tested for. My problem - a flickering backlight - remains exactly the same. They did a sloppy job reassembling too (stripped HDD screw, wire channels not used, gunked up LCD). Wow.
I'll update again after RMA #2.
Just received my laptop back again. This time they replaced out the panel and the issue appears to be resolved.
