Lenovo X220 Tablet Fan Turn Off after few minutes

2017-07-27, 18:25 PM

Hello,

 

The fan in my lenovo X220 tablet stops working after awhile from turning the device on (after around 10 minutes). This causes the temperature of the processor to always be above 90 degree C (using TPFanControl V 0.61).

 

The fan control software shows that the fan is turning at 4060 RPM, but there is absolutly no air coming out!

 

I recently re-applied the thermal paste, and the problem (fan turning off) "might" have started after re-applying the thermal past - I did it in a local computer service shop.

 

I tried to update the BIOS, but the battery does not work and the installation does not start (it gives me an error) because of that.

 

I have been using my X220 for six years with no problems and I currently run windows 10.

 

Please let me know if you have any idea on how to fix this issue.

There are only 2 parts involved - the fan and the motherboard.  If the fan bearing gets hot and seizes, it would spin at start-up to avoid the fan error message.  Fans are cheaper than motherboards, so if it were mine, I would try a new fan.

Thanks for the reply.

 

I know little about this. I thought it can not be the fan because it does rotate at the beginning. If the problem is in the fan, will it still work at the beginning and stop after few minutes to avoid the fan error? 

 

If I try to turn on the laptop when it is very hot (when I just turned it off), it won't start and it gives me "fan error". So I have to leave it for awhile to cool.

I still think the fan bearing seizes when hot.  That would allow the fan to spin for 1/2 sec. at the beginning (avoiding fan error), but would stop when it was hot.  It would not start again until the bearing cooled
