OT, but the adapter signals to the machine?
No..... the slim adapter radiates a RF noise of some sort which is impacting the machine.

Your are exactly right. I have the same problem in my X220i and Google about it. It exactly produce the same problem and result as other user in this forum... so amazing the pointer stop jumpy when I touched the metal at display.

It's all a big joke. Either the moderators have stopped visiting the forum or hides from this thread. The touchpad jumps crazy as soon as i:
1. Plug in the AC-adapter
2. Plug in an ethernet cable
There's probably some serious flaw in the design of the chassis/mainboard, transferring electricity to the touchpad.

Just got an X220 with the slim battery. I had the issue and since the power supply was emiting a crackling sound I contacted support, and they sent me a replacement battery. You would think that after 1/2 year of the issue being on their radar, you would think that the support personnel would know about it and not send a replacement.
Can't believe that after 1/2 year there we are still in the same situation.
Our department pushed and pushed and finally received the OK to use Lenovo laptops, but with the amount of issues that we are having and the lack of good support, will likely go back to using Dell.

Thanks for the update, hope for some good news soon...
do you mean the power supply was buzzing and popping? I assumed that was normal for my slim adaptor or have I got it wrong?!
