Fan of Thinkpad yoga not spinning

Hi,

I have just realised that the fan of my thinkpad yoga is not spinning at all. I followed  this post and set the fan to full speed. I do not think the fan spin and when check the fan status I get:

cat /proc/acpi/ibm/fan
status:         enabled
speed:          0
level:          7
commands:       level <level> (<level> is 0-7, auto, disengaged, full-speed)
commands:       enable, disable
commands:       watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))

Does anyone knows how to fix this?

Cheers.

Edit: After having enabled the fan manually and  rebooted a few time , it seems to work. However, changing the fan speed manually seems to have no effect.

Do you by any chance have a different OS you can test it with? You will most likely want to test with Windows first to indeed see that there is no hardware issue and in a different Linux based OS to test if there is a config error.

Also, take a look at your UEFI or BIOS to see if there is any information there.

EDIT: Didn't see your edit. Good to see it working.

Thank you for your answer,

Has I said in the edit, it is now working I do not know why. I suspect driver issues.

Yes I checked the UEFI and there is no mention to fan. Yes I was going to try on a live ubuntu.

Cheers

P.S How can I add solved to the topic title?

To add solved, edit the first post. You can edit the title there if I'm not mistaken.

Keep a tab on the fan. If it fixed itself without reason, it might also unfix itself without reason.

Ok, actually I was in this state

cat /proc/acpi/ibm/fan 
status:         disabled
speed:          0
level:          0

Then I used this to enable it. Then it started working again after a while.
I removed the option for Thinkpad_acpi and now I have

cat /proc/acpi/ibm/fan 
status:         enabled
speed:          0
level:          auto
