    Power down USB ports in sleep mode?

    KME

      NUC6i3SYH and Win10

      I am using my NUC as an HTPC and it is desirable that the outboard DAC, which is connected through and powered by a USB port power down when the computer goes into sleep mode.   It appears that all the USB ports still provide power when the computer is powered down.   Is that true, and if so, is there a way to power them down when in sleep mode.

          As far as I remember, you can switch this feature off for any USB port via BIOS settings

            Actually, that's not quite correct. In BIOS, you have the ability to configure whether or not the USB ports are powered while in S4 (Hibernate) and S5 (Powered Off). You do not have this ability for S3 (Sleep); the USB ports are always powered in S3 (Sleep).

              Hello KME,

               

              Scott, is right. You can only configure these two options within the BIOS. 

               

              If you disable "Allow the computer to turn off this device to save power" from Device Manager should help, this will keep the USB ports inactive during sleep mode.

                  I disabled the USB ports as suggested but it didn't seem to make any difference.   Outboard device is still powered up when in sleep mode.   Please advise

                    The yellow ports will always powered up when in sleep mode, the blue ones should be turned off.

                     

                    I followed the instructions posted before, and it disabled the USB power when the unit was in sleep mode.

                     

                    Regards,

                    Amy.

                      Amy, thanks but it's still not working

                      - Device was plugged in to the blue ports. 

                      - Just to make sure that I am following the instructions: 

                           Device Manager

                                Universal Serial Bus Controllers

                                     Intel USB3.0 extensible Host Controller - 1.0 (Microsoft)

                                     Properties

                                          Power Management Tab

                                               uncheck "Allow computer to turn off this device to save power"

                                               OK

                       

                      Are my actions correct?

                       

                      Thanks again,

                        That is correct Kent, those were my specific steps.

                         

                        Please, let me set my Intel® NUC Kit NUC6i3SYH one more time and check if I am able to get the same results. I will share them here.

                          Hi Kent,

                           

                          I tried changing something else in the power Options, and I have some interesting results. These are my new steps;

                          1. Go to Power Options.
                          2. Click on change Advanced settings.
                          3. Change plan settings for Balanced.
                          4. Click on Change advanced power setting.
                          5. Find USB settings, and click on USB selective suspend setting.
                          6. Disable it.

                           

                          Once I followed these steps each time I plugged a couple of USB devices to charge they did not get any power; however, this only happened with some devices. For example, I plugged an iPhone and a Sony device and these did not charge, but I tried with some Samsung phones and they were powered.

                           

                          Regards,

                          Amy.

                            Amy, tried the above steps but the device is still powered up.  Any further suggestions?

                             

                            Thanks again

                                Yes, it is a Meridian Explorer 2 DAC.

                                 

                                Thanks again

                                  Hello KME

                                   

                                  In states (S1-S3), volatile memory is kept refreshed to maintain the system state. Some components also remain powered so the computer can wake from input from the keyboard, LAN, or a USB device, and here are my results from testing with "Portable Device Charging Mode" set to "OFF" under the USB Configuration in BIOS:

                                   

                                  - Clicking "Sleep" on the Power Menu still provides power to the USB blue connectors

                                   

                                  - Either selecting "Hibernate" on the Power Menu if available or pushing the power button on the unit to "Hibernate" the system doesn’t provide power to the USB blue connector.

                                   

                                  This is the expected behavior.

                                   

                                  Thanks,

                                  Ronny G

                                    That seems to do the trick.  I didn't change anything in the bios but when I add hibernate to the power options menu and select hibernate it seems to power down the USB ports and the device that is attached.      It does create a minor inconvenience in that the computer can no longer be awakened using the keyboard because the keyboard dongle is plugged into one of the front (yellow) USB ports and they appear to be unpowered.   So I will need to wake the computer with the power button but that is OK in my configuration and it is good to not have my DAC powered all the time.    

                                     

                                    Thanks
