How to stop charging with type-c/thunderbolt port when NUC is power-off?

[勇焦000]

My device is NUC8I5BEH,I tried to stop charging with thunderbolt port when the NUC is off,but I don't know how to make it.Because I'm using an EGPU device,when I power-off the NUC,EGPU's PSU fans still work,because the thunderbolt type was still charging.

I don't have NUC8i5BEH to verify this, however you may try this: In Bios Advanced > Devices > USB, set Portable Device Charging Mode to OFF.

Thankyou for answering my question,I'v tride your advice ,but didn't work it only affect front yellow type-A port

[勇焦000]

I knew what's the problem ,I set as you said,it doesn't work ,even the front yellow type-A port still provide charging when NUC is off,how can I fix it?

[LeonWaksman]

I'm not sure if this will work, however try it:

In Bios Advanced > Power > Secondary Power Settings enable Deep S4/S5. This will enable deep sleep and will affect also wake up capabilities.

Hello 勇焦000,

Thank you for posting on the Intel® communities.  

This is expected by design. USB power will be provided by the USB port even if the unit is powered off. In BIOS as LEON indicated, you can enable or disable Portable Device Charging Mode, but it will cause the unit to either provide extra power during S4/S5 sleep states or not. I will share your feedback with the appropriate team for future consideration.

Hello 勇焦000,

We were further investigating this case, we haven't been able to reproduce this behavior, would you mind to check with your device vendor, whether there is any firmware fix (update), like the one on the link below?

https://www.gigabyte.com/us/Graphics-Card/GV-N1080IXEB-8GD/support#support-dl-firmware

Please provide the model of your eGPU, the example above is for Gigabyte and their Gaming Box had this issue which got fixed with the new firmware release.

Also, please install the latest Thunderbolt™ 3 Legacy Driver for Windows® 10 for Intel® NUC.
