If you lower the brightness to the recommended default battery setting of 4 out of 16 the screen flickers. The brighter you put the display at, the less noticeable it is. At 2 which would be useable if needed the flickering is really bad. Plugged in at 14 brightness setting you can't see any flickering. But the lower you get the more noticeable it is. I had it at 7 which seemed alright but is really draining the battery, then I used it in the afternoon sunlight and I notice the flickering again unless I really turn up the brightness.
It isn't a screen cheapness issue. I have a lenovo ideapad s10-1 atom here that I bought for $199 and the screen is really nice. I was really looking forward to getting a better version of that screen. I have a HP tx2500 tablet and the screen is really dark/washed out but no flickering at the lowest levels. I usually go for cheap bottom of the line laptops and have never seen something like this at the lower brightness levels.
There is a "x120 flickering" thread. But it really deals with glitches / bands going across the screen and the bios update 1.11 fixed that. I read all the reply’s and they don't help. The varibright is off. The refresh is at 60hz. The bios has been updated to 1.12. The video driver is the latest talked about in the flickering thread.
My issue almost like it is an Inverter board issue, like the screen might not last that long. It is like I have a CRT and it is at 50hz or something. This is really annoying out of the corner of my eye I can see the screen constantly slightly flicker, it gives me a headache after awhile. It is really the most noticeable with web pages with white backgrounds.
Is this a feature of all the x120e laptops or is this a bios issue, it can't be driver issue as it happens at the bios screen. This is really the best laptop I have ever owned except for this major issue with the display. I didn't buy an 11.6 inch machine to leave at home plugged in, and what tech didn't think to check the lower brightness settings. What is the quickest way to return the laptop for refund, without the annoying techs reading off scripts?

Another forum member had the same problem: http://forums.lenovo.com/t5/X-Series-ThinkPad-Lapt
He/she never posted a solution, but I assume it's as you think, a hardware issue. My x120e doesn't do it, but my Macbook does -- it's done it for the past 4 years I've owned it. It's fairly obvious when you take a video of the screen, but I don't really notice it in real life... I suppose it's like how some people don't notice 60 hz CRT flicker (which I notice, but I'm fine above 72 Hz).
