Hi, I'm having some trouble with my X301 display... Several days ago it began to show severe screen distortion/flickering when unplugged from AC-power (see video). The distortion only occurs sporadically and disappears once I connect it to AC again, leaving some marks on the GUI behind. I have no idea what could be the cause of this, any help greatly appreciated...

Lenovo just released a new intel video driver. In the release note, they mentioned something similar to what you experienced. We may want to give it a try. You may have to go to lenovo's website to download the driver directly. My X301 has no problem so far. If the new driver does not solve the problem, I recommend calling Lenovo to have the machine checked. My X60T used to have screen flickering and they fixed it promptly. Good luck!

ouh, I'm sorry about the pics...
Thanks for that hint bluewale - I must have missed the new video drivers when I downloaded the latest BIOS yesterday. Unfortunately they don't solve the problem for me

I saw the picture. It seems severe. I think it is more likely a hardware problem, maybe the LCD converter. I had similar problems with my X60T, but not that bad. You should call Lenovo tech support to have your machine serviced.

Looks like a GPU issue to me, not LCD

Still I find it weird that it only happens while on battery power - at the moment I'm trying to reproduce it with Intel graphics power management turned off...

Okay, it seems that disabling the "Intel Smart 2D Display Technology" (whatever that is) setting at the power feature tab for the graphics driver "solves" the problem. I only hope this is a software/driver issue and not caused by an underlying hardware problem...

Could you tell me where I can find the "intel Smart 2D..." thing? thanks.

Sure: just right click on that Intel Graphics icon in the systray, then properties - display settings - power settings - modify settings and you got all kinds of different power saving stuff there.
