there is no need for logs because I checked them all and there is no clue about 
the cause.
ANYWAYS, a guy with the same problem on a simlar notebook solved by patching 2 
kernel modules.

Title:
  Touchpad not working and locking CPU

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Notebook: ASUS GL703VD
  Touchpad: probably ELAN clickpad

  it seems to be connected to i2c bus

  the modules loaded are elan_i2c and multitouch_hid

  the multitouch hid module take almost 100% of cpu and the mouse cursor
  moves badly (loosing it for a second or 2 then resuming) also feature
  clicks and doubleclicks and sensitivity problems.

  doing rmmod hid-multitouch.ko (or rmmod multitouch_hid) and
  blacklisting the module solves the cpu problem but obviously the
  touchoad is dead.

  SEVERITY VERY HIGH
  It probably affects many other ASUS models.

  (the touchpad works perfectly in windows 10 by the way)
