I've noticed that on some occasions after multiple suspend/resume cycles that the touchpad can become unresponsive. When this occurrs, the trackpoint still functions well, but the touchpad and its buttons become useless.
This seems to randomly occur. I ran a 30 cycle test on this machine and didn't see the issue occur, but did after closing and opening the lid 3 times, allowing it to suspend between each closure and open.
This has been seen on a couple systems only, (the other was the E320, IIRC) and has not been observed yet on other Lenovo machines.

Would it be possible for you to test the latest upstream kernel? Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.
