I have the 16.04 LTS for my Lenovo G50-80 laptop.
The problem is: cooling fans are working for almost all the time (that's really noisy and boring).
I have this problem since purchasing my laptop a 6 months ago, and I was searching for a solution during this period until now.
I followed these steps:
1) Install the lm-sensors and fancontrol packages.
2) Configure lm-sensors
In terminal type
sudo sensors-detectand answer YES to all YES/no questions.
The first "YES" gives me this:
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y
Module cpuid loaded successfully.

At the end of sensors-detect, a list of modules that need to be loaded will be displayed. Type "yes" to have sensors-detect insert those modules into
So the following lines are added to the file
# Generated by sensors-detect on Mon Sep 5 13:50:31 2016
# Chip drivers
sudo service kmod start. This will read the changes you made to
/etc/modulesin step 3, and insert the new modules into the kernel.
3) Configure fancontrol:
At this stage,
sudo pwmconfig returns
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
I tried to fix this problem using this link but no way, always the same problem with the command
What seems abnormal:
sensors returns only
Adapter: ISA adapter
Physical id 0: +49.0°C (high = +105.0°C, crit = +105.0°C)
Core 0: +48.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +46.0°C (high = +105.0°C, crit = +105.0°C)
acpi -t returns nothing.
May be the kernel doesn't detect fan controller for such laptop model.
Note that there is no way to control fans from BIOS. And
cat /proc/cmdline returns
BOOT_IMAGE=/boot/vmlinuz-4.4.0-36-generic.efi.signed root=UUID=b606c0de-3f11-439e-bdd2-c17579566c57 ro quiet splash acpi_enforce_resources=lax vt.handoff=7
I don't know if there are a possible solution for the overall problem. I despair.
