Ivan Danov, because Samsung does not easily reveal what the latest BIOS is for a given model, could you please download the latest firmware as per https://www.samsung.com/us/support/owners/product/NP900X4C-A04US, and advise if a BIOS update is available? If so, when you update to this, does it change anything?  If not, 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

Thank you for your understanding.

** Summary changed:

- lm-sensors does not detect fan sensors, provided by i2c_i801
+ [Samsung Series 9 NP900X4C-A04US] lm-sensors does not detect fan sensors, provided by i2c_i801

Title:
  [Samsung Series 9 NP900X4C-A04US] lm-sensors does not detect fan
  sensors, provided by i2c_i801

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  lm-sensors cannot detect my fan sensors, so my fan is not working at
  all and that makes my laptop have very high temperatures, which is
  very bad for it. I have tried several times to run sensors-detect, but
  only coretemp is detected, although for Ivy Bridge (Panther Point
  chipset), there should be more sensors provided by i2c_i801.

  While looking for a solution, I have found an ongoing discussion on
  http://forums.gentoo.org/viewtopic-t-946718-start-0.html, where they
  have concluded that this is probably a kernel bug.

  I have created a bug report couple of days ago for lm-sensors, but
  they have it was marked as invalid. I create another one, since it is
  definitely a bug, a very problematic one, since my laptop has crashed
  already couple of times due to overheating.
