This issue is definitely there with the 90W power supply. In fact, the first time I switched on the laptop I used the 90W and made a hard disk image under Linux.
So it's neither PSU nor driver related.

I would agree with the timings mentioned: 15-30 minutes to burn in and then 30 minutes plus to fade unless the screen is rapidly switched (e.g. gaming, film etc). The burn is not visible on a white or black background, but mid-tones make it very clear. Lowering the brightness obviously lessens the impact (running it at 10 rather than the full 15 for example), but this is not a solution. I tried switching the display to 60hz refresh on the off-chance, but no change as I would expect. I imagine Lenovo's supplier on this one is going to get a kicking.

"I imagine Lenovo's supplier on this one is going to get a kicking."
Unfortunately it seems as if Lenovo has decided to kick its paying customers instead by pretending there is no problem. If Lenovo doesn't fix the faulty screen, I wonder how few current customers would actually decide to buy another Thinkpad from them again?
To answer the previous question asked of us, in my situation the ghosting begins in 5-10 minutes from use. It progressively gets worse until you can read text left on the screen and even see traces of color. This is a horrible, and inexcusable, problem for me since I use this tablet professionally in a photography studio where screen quality is very important.

Do you see gradient banding on your X220? If screen quality is very important to you, gradient banding should be even more of a problem than ghosting. I noticed it almost right away but I seem to be the only one who has mentioned it. I don't know if it's caused by the screen itself or the Intel graphics adapter.
Here's a test image: http://www.lagom.nl/lcd-test/gradient.php. Compare it to other laptop and desktop monitors. Gradients are smooth on my desktop PC (Dell monitor and low end Radeon card) and MacBook Pro, but banding is easily visible on my X220 with IPS screen.

1) Ghosting premium screen
2) Fan pulsing and weird noise
3) touchpad issues
4) throttling issues that renders the X220 to perform like a 5-6 years old laptop
5) Issues with SSD added
I have started a tracking thread on unresolved issues here:
I am not aware of any touchpad issues. Please point me to the relevant thread.

There's no gradient banding evident at all on my X220 IPS display.

Thanks for your feedback, billbolton and underst0rm.
Very interesting. I noticed gradient banding on my X220 since the first time I turned it on. I'll talk to Lenovo support about it.
It's a separate topic from this thread and I've started a new thread here:
