I am facing issues with Thinkpad T410's fan. Now and then my fan stops working (meaning 0 rpm). Long time, the only solution for me was to shutdown (not to restart, instead power off) the system and then boot again. (Which is, what you can guess, not a good solution. Sometimes I even had to cancel cpu-heavy tasks, to avoid data corruption, because of the systems rescue shutdown, when the temp goes higher than 100 C.)I found out that going in suspend mode also helps bringing the fan back to work. I would like to know which processes are started when the computer is coming back from suspend mode, so I can force the fan to start again without even going to suspend mode.To make sure: I don't want to control the fan itself, but I want it to restart manually. 
Restart fan manually in Linux

Using the following line allows me to restart the fan without suspending my laptop.echo disable | sudo tee /proc/acpi/ibm/fan; sleep 5; echo enable | sudo tee /proc/acpi/ibm/fanThanks to @Stephen Harris
