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 ** Tags removed: needs-full-computer-model -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1161699 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.
