Fan stays on when it's in sleep mode

2018-06-30, 11:17 AM

Had my ThinkPad X1 Yoga (3rd Gen) for almost a month now, and I've notice something about the fan. The fan stays on during sleep mode and doesn't go off. Not sure what the cause for this is. Tried to reach out to Lenovo about the situation, but didn't get much help. Any help or clues, would be grateful.

Hi mrcambo87,

 

Greetings from Lenovo.

 

As you have mentioned that the fan always run even in sleep mode, suggest you to update your BIOS to the latest one, then restart the computer and enter into the BIOS.

 

In your Power Management, please choose ACPI S3 sleep mode. It will turn off the fans when go to sleep.

I think there's a bug here beyond just the sleep mode.

 

I understand the modern sleep mode allows the fan to keep running. That's OK. However, while the laptop is asleep, it's staying in the high fan state and not shutting off for hours and hours. I'll touch the laptop and it's completely cool. I open the lid, and immediately the fan stops/slows significantly. Then I can close the lid again and the fan will remain off/negligible.

 

I suspect this bug occurred with an update.

 

Disabling the modern sleep would be a workaround, not a solution.

 

I just received a new X1 Yoga 3 due to hardware issues with mine and I hope it doesn't occur on the new one, but I'm afraid to update the BIOS.

Hi Ashwin!

 

Please make it possible to have this S3 sleep, into the X1 Carbon as well.

 

We are all expecting this fix in order to have some sleep :D, we cant use the machine like this, having to use hibernation as a workaround since is not the same.

 

Thanks for your help!

Lenovo ran auto-updates on BIOS and drivers simultaneously on the replacement laptop and now the fan issue is present on this laptop too. It must be a regression in one of the updates.

To clarify: I understand the fan can come on in "modern sleep." That is NOT the issue! The issue is that if the fan is on before going to sleep, the fan will never shut off during sleep! It will stay running for hours and hours and hours and never use its temperature sensor to realize it should shut off. As soon as you open the lid to wake up the laptop, within a couple of seconds the laptop realizes it's cool and shuts off the fan. Then you can put the laptop back to sleep and the fan remains off. Please fix.

All,

 

This "fan running during sleep" issue should be fixed in the latest BIOS update.  If not, please tell me exactly what BIOS version you are on, and we can double-check it here.

Yes please!  This is a serious business machine, not a tablet or phone.

Thank you for the update, however, I updated today to the latest BIOS update available (1.21) and the issue is still present.

Model is 20LD.
