    If you have a Dell laptop, such as my Inspiron 5000 17 Series, you may find that devices connected via USB, such as yours Powerful phone, do not change after switching the printer to sleep.

    I went to BIOS, DEVICE MANAGER > USB POWER, OPTIONS, etc. but I didn’t find all permissions.

    I called Dell and they previously incorrectly told support that the issue was now with my connection. In particular, devices are only charged via USB3 vents when the laptop is in sleep mode. It’s just not right.

    After an hour of fiddling, diagnosing and flashing the BIOS, we have found the current solution.

    If you want USB connected devices to charge while your computer is in bed, you need to ENABLE WAKE ON USB SUPPORT in BIOS:

    1. Turn off the laptop.
    2. Press and hold the F2 key.
    3. Press the configuration key.
      1. Keep pressing the F2 key until you see ENTER CONFIGURATION in the upper right corner of each screen
    4. Expand to one side CONTROL P BIOS > USB WAKE ON SUPPORT
    5. Click on the USB WAKE ON SUPPORT field anywhere
    6. < li>At this point, click END APPLICATION

    7. Restart your computer

    How do I enable USB Wake on Windows 10?

    Hold down the F2 key. Press the power buttons. In the BIOS, expand POWER MANAGEMENT > USB WAKE SUPPORT. Click the ENABLE USB WAKE SUPPORT checkbox.

    You should now power on ALL Dell USB ports, even if the laptop in question is in sleep mode.

    dell bios usb wake support

    The XPS 7590 lacked basic BIOS features that even the other lower-end Inspiron 7590 has. The lack of “Enable USB Wake Support” prevents waking up with the laptop’s mouse/keyboard/touchpad, and I believe this may also be the reason for these Bluetooth devices to fail after resuming from S3 standby.

    dell bios usb wake support

    Since buying the XPS 15 7590 over a year ago, I have had (and many still have) problems with continuous power saving.


    Modern sleep is terrible, although switching to S3 sleep by disabling the sleep connection in Windows 10 (https://www.reddit.com/r/Dell/comments/h0r56s/getting_back_s3_sleep_and_disabling_modern/) also causes issues and other issues. especially portable. (For comparison, I have an Inspiron 7590 that runs the S3 Sleep just fine)

    XPS Seventeen 7590 has trouble disabling sleep modeOptions for connecting and thus enabling S3 hibernation mode:

    1. Bluetooth disappears and doesn’t work after waking up

    2. Unable to activate if keyboard/mouse/tablet should be controlled by power button.< /p>

    1. For Bluetooth, the problem that disappears seems to be related to the USB Root Hub, disabling and enabling the exact “USB Root Hub” connected to the device brings the WiFi back to life (more appears in device manager). .

    A workaround for the above has been posted (https://www.reddit.com/r/Dell/comments/ge7f7v/solution_xps_15_7590_disappearing_bluetooth_after/) but it’s a shame people are resorting to it on a brand new premium laptop.

    2. Device cannot be woken from S3 sleep mode using keyboard/mouse/touchpad, apparently caused by USB not enabling wake support in XPS BIOS 7590.

    Below is a screenshot comparing the BIOS of the Inspiron 7590 and the BIOS of the XPS 7590.

    The XPS 7590’s USB Wake Support now only has a Wake on Dell USB-C Dock option, while the newer Inspiron 7590 has an option to Enable full USB Wake Support and Wake Up u S3 hibernation level works with this keyboard/touchpad.

    Why the XPS 7590 doesn’t need the correct USB Wake Support option in the BIOS

    Please, XPS 7590 users can have the correct “USB Wake Support” in the BIOS and finally do something that causes the Bluetooth device to not work after waking up.
