To see what programs are using the most CPU power, press CTRL+ALT+DELETE and click Task Manager. This is especially important if you are not working with a high-performance machine.
These include:įollow the steps below to see if any of these solutions fix the problem. If the fan on your Dell laptop will not stop running, you can try a few things that may solve the issue. How to Stop the Fan from Constantly Running on a Dell Laptop Overheating laptops are no joke, and the problems that cause them should be taken care of immediately! Let’s take a deeper look into the possible causes and how to address them. The most common reasons include an overload in the CPU, dirty or obstructed fans or vents, poor ventilation, damaged components, or outdated BIOS or drivers. There are several reasons why the fan may be running constantly. It seems like the fan is constantly running at high speed, and you are wondering why.

I have chceked this on BIOS'es: A11, A09, A08 It seems that it could controll and read fan speed, but it is not implemented (lm-sensors site seems to be down time)ĭoes anyone have and idea how to tackle this edit
It seems that dell-smm-hwmon could be not used if there was driver for ITE ITE8512E/F/G as sensor-detect finds it. But the catch is that without dell-smm-hwmon I get no pwm control device for fan so, cannot read or change fan speed. I narrowed it down to dell-smm-hwmon kernel module and after blacklisting, polling sensors (with sensors or xsensors) works normally. The same issue seems to be with i8kutils - when run, polling/writing hwmon pwm and input from speed makes system unworkable. I discovered this hard way when tried to run xsensors and barely could shut it down as there is no other activity during this pauses and xsensors polls sensors quite often. It seems that there is some problem as whenever any programm was reading/writing pwm/speed laptop hangs for 1-5 seconds. When used pwmconfig controls fan speed via hwmon device and reads/writes speed. I tried fancontrol/pwmconfig and i8kutils. I had no issues with wmi and function keys, bluetooth and wireless, graphics.īut one thing that I wanted to tweak was fan speed.
During last week I have tried to install Xubuntu 14.04 LTS and Ubuntu Mate 15.04 on my Dell Studio 1537.
