In bios setting, the following details:
Bios version 2.15.1227 copyright 2012 american Megatrends
MB series : w310cz
Bios version : 1.02.04
KBC/EC Firmware revision : 1.02.02

I see on this repo
http://repo.palkeo.com/clevo-mirror/W310CZ/
that this bios version and EC revision is dated on 05/20/2013.

Maybe it would be a good idea to update to 11/11/2013 versions:
i.e.:
Bios version : 1.03.02
KBC/EC Firmware revision : 1.03.01
(which normally integrates previous update)
Because previous update (09/12/2013) update Intel micro code.

Sandy/Ivy bridge support natively usb2, and I think that sentelic touchpad is connected on usb...
so, maybe update intel microcode could help...

what do you think about thi bios/EC update ?

Title:
  erratic jump/selection sentelic touchpad

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:

  Hello,

  I've sentelic touchpad (clevo w310cz) with ubuntu 14.04.
  as mentioned https://bugzilla.kernel.org/show_bug.cgi?id=43197, cursor jumps and select *anywhere* on the screen.
  as mentionned https://bugs.launchpad.net/ubuntu/+source/linux/+bug/311869, I make a report here

  To minimize erratic jump/selection:
  - I disabled mutitouch option in touchpad-configuration GUI (two finger scrolling)
  - I had "i8042.nomux=1 i8042.reset=1" to my GRUB_CMDLINE_LINUX_DEFAULT (/etc/default/grub).
  - I use too
  synclient PalmMinZ=1
  synclient PalmMinWidth=1
  synclient MaxSpeed=1

  I am available to test possible solutions or provide more information
  Thank
