s230u/3347/4hu an update to your computer's buggy and outdated BIOS is
available (1.71). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it address the issue?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  Keyboard and touchpad malfunctioning on Thinkpad Twist

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I don't know if this is really a kernel bug or if it's any other
  component, please help me know how I can diagnose the problem better.

  This is a bug I have been experiencing with both 15.04 and 15.10,
  while this was not a problem with earlier distributions --
  unfortunately, I don't remember which one in particular was actually
  working.

  I have a Thinkpad Twist -- a hybrid laptop with touchscreen. The
  touchpad almost never works (even though sometimes, erratically, it
  does). The keyboard sometimes stops working, and works again after a
  suspend/resume cycle. Sometimes it behaves as if a key is stuck.

  When running xinput --list, I don't see the touchpad. The touchscreen
  and external input devices connected via USB, however, work fine.

  I was thinking this was a hardware problem, but on the same machine
  with Windows the problem does not appear to present itself.
