Is it possible to re-install the previous BIOS version on this machine,
to see if the BIOS upgrade in fact caused this issue?

Title:
  On Lenovo Thinkpad Twist internal mouse does not work after turning on
  machine, only works after reboot

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have a Lenovo ThinkPad Twist (convertible ultrabook with Core i7
  processor) with touch screen, touch pad, rubber nipple mouse, and
  external Bluetooth mouse. From these 4 mice 2 always work, the touch
  screen and the external Bluetooth mouse.

  The touchpad and the nipple do not work right after turning on the
  machine, only when I reboot the machine they work after rebooting. I
  have observed the problem only recently, so it is perhaps triggered by
  the BIOS upgrade to version 1.57. The problem is independent of the
  Ubuntu version. I did not only observe it on the installed Raring and
  Saucy systems but also with several live CDs of older Ubuntu versions
  (Quantal, Precise).

  There is also another user with the same problem. See

  http://www.iasptk.com/ubuntuwp/tag/13-10/

  and search for "twist". Unfortunately, the question got removed from
  Ask Ubuntu, but one can still access the dmesg output from this user
  on
