Fan is not running on X201

My X201 was getting really hot when I work. At some point SpeedFan showed 103C as a core temperature. Today I remove the keyboard and turned on the laptop. What I found is that the fan runs for few second when you turn on the laptop, and stops. While I was working for the next 5-10 minutes, the fan didn't start running. I think this is why my laptop gets too hot. And question is how do I make the fan running? Is there any setting in the BIOS that I should check? Any software that will start the fan running?

Re: Fan is not running on X201

Hi,

 

Welcome to Lenovo Community Forums!

 

I’m sorry to hear that Fan is not running properly in your Lenovo ThinkPad X201.

 

It seems your system is overheating since the fan is not running properly. Are you getting any error messages during system startup? Is the system shutting down abruptly?

 

Go to BIOS and press F9 to setup default settings. Update BIOS to the latest version and check. Make sure that Fan assembly and the system gets enough power supply, the air vents are not blocked and there is a proper air flow. Check if there is something blocking the free spinning of Fan.

 

Refer the hardware maintenance manual to understand how to disassemble and check the system.

 

Best regards,

Mithun.

Re: Fan is not running on X201

mithunr, thank you very much for your replay. 

 

First I've resetted BIOS settings to the default with F9 it didn't help. Then I updated the BIOS to the 1.40 version (is was 1.15 ver) no results. Hot air comes out from notebook when it is just started, so there is no problem with air flow.  Unfortunately these are not working for me. 

 

And there is one more problem that I forgot to mention in my fist message. Whe I shut down the laptop, windows freezes at the point when it says "Shutting down".  Only pressing the power button for few seconds will turn off the laptop.

Re: Fan is not running on X201

Try to install TPFancontrol and see whether you can manually trigger the fan to run.

Also, have you tried a Linux Live CD to see whether the fan runs in Linux environment.

Finally did you ever spill any liquid on the laptop before?

Re: Fan is not running on X201

I installed elementary OS Luna on it, but again it didn't help. Then I completely disassembled the laptop.

 

When I connected 5V power source to the fan just to check it works. Which means the fan itself is ok. Tomorrow I am going to try with another fan from other laptop.  

 

What part of laptop runs those fans? I mean how a laptop detects that it is getting too hot and starts running the fan? Maybe that part on my laptop is broken?

 

Hope it'll help.

Re: Fan is not running on X201

there are several temperature sensors, i think there is temp sensor near the cpu socket and one within cpu.

If your temperature is detected this means, it is most likely the fan controller like the BIOS EC circuit that is having issue.

Re: Fan is not running on X201

There are temperature sensors in the CPU and also on the motherboard. They could be malfunctioning. The CPU is unlikely to fail this way, but it is possible. In this case, the CPU is soldered to the board, so any sensor failure is a board failure. Also, just because the fan spins at startup, it does not mean the fan is good
