Apply the following BIOS settings:

Advanced > Devices > USB set the Portable Device Charging Mode to OFF.

Advanced > Power > Secondary Power Settings uncheck the USB S4/S5 Power  (Deep S4/S5 should be set to Disable, otherwise this setting is hidden and Disabled)

Hi,
Firstly, I would like to thank you for your answer.
The new configuration works except for the rear usb-c and the front yellow usb slot.
At first, it seemed to work as usb-c was off. But as soon as I tested the front yellow usb slot, both slots (front yellow usb and rear usb-c) are powered.

Hi @Thierry1 

After applying the new setting in BIOS, did you clicked on F10 confirmed by "Y" to save those settings?

Yes, I checked several times that the New configuration was taken into account.

Are you talking about the state immediately after you plug in the NUC or are you talking about the state after you shutdown or suspend? I believe that the former state will always have the ports powered (you have to complete a full POST before the BIOS will program them to power off) and the latter state will (ok, should) follow the BIOS configuration.

I don't know what you mean by a "full POST" As f10 records the full configuration, but my concern is the usb power state after shutdown.

Hi @Thierry1 

1. I don't have NUC BE , however I've checked this on two other NUCs I have: NUC HV and NUC DN. Those NUCs have the same Visual BIOS as your NUC has. After applying setting in BIOS as per my post above, there is no power in USB ports, neither USB - C and neither the Charging USB.

2. So, if you applied correctly the settings and still you have power, I suggest that you should update your BIOS to the latest Version: 0085  using BIOS Recovery by Power Button Menu Then set the correct settings for USB and try again.

Still not working after updating the bios. Maybe à jumper issue?

I can concur. While I am seeing the blue USB 3.0 ports power off, the yellow USB 3.0 Charging port and the USB-C port are staying powered.

Intel Customer Support: This does not jive with the TPS. Please have this reviewed against the PRD.

Hello all,


We are currently reviewing the technical product specifications for this device and investigating this behavior.

I will provide an update in the thread as soon as possible.

Hi everyone,

I got confirmation that there are no plans to change this behavior.

We will be looking into the existing documentation to make any necessary adjustments to reflect the actual product behavior.
