I work for IBM and have had three Thinkpads for work. Let me just say that the touchpads on my other thinkpads (T30, T42p, and T400) were excellent. My girlfriends Ideapad U460 touchpad is also excellent.
I just got my EDGE 14 for personal use a few days ago. Touchpad has been a HORRIBLE. (0578-XF9 using Windows 7 32 bit.). I have been searching forums and boards all over the place and tried so many different combinations of settings to get my touchpad to get to the level of my other Lenovo machines.
Among the many problems I have had.
-Cursor would move to a different part of the screen for no reason
-Cursor would freeze if touchpad wasn't used for a few minutes and I have to tap the touch pad really hard or rub it to get it to move again.
-General scrolling seemed to behave differently in different applications. Sometimes ok other times choppy or jumpy. It always works fine in the touchpad practice demo application, but was very inconsistent and terrible with itunes.
-Horizontal scrolling was unbearably slow.
-Three finger flick was very inconsistent
-Pinch zoom was very inconsistent
-Scrolling in itunes didn't work
-Two finger scroll was inconsistent. Sometimes it worked, sometimes it didn't work at all, or would be very choppy.
-The Rotate gesture would almost never work.

Answers
- How long has the machine been turned on before the issue started to happen? Issues happen randomly. Cursor freezing happens alot after resume from sleep mode. But it can happen any time.
- What were you doing or what programs were running before the issue happened? Touchpad freezes for all programs. Scrolling problems are inconsistent in all, but really bad in itunes.
- How you temporarily fix it? By system reboot? FOr cursor freezing, had to rub or tap the touchpad and wait a few seconds before it started responding again. For the itunes problem, I had to edit a configuration file in the original touchpad program directory (tp4table.dat)
NOte: I just installed the synaptics driver from the synaptics website (version 14.0.3.0). Hopefully, it solves some of the problems. I will write back if it does help.
Personally, I think it is a hardware issue.
