    My Lenovo Legion 5 (82AU00BVUS) keeps waking from sleep, even though I've taken all sorts of steps to prevent it. WinVer: 20H2 (19042.867)

    System bios info:
    SMBIOSBIOSVersion
    EFCN38WW

    Here's what I've done so far:

    1. Disable wake timers

    I completely disabled wake timers in Power Options:

    2. Checked wake_armed devices

    I checked which devices are "wake_armed" in powercfg. Armed devices include the keyboard, and the ethernet port of an external dock, which is strange because when I look in device manager at that ethernet port, the enable wake is disabled, so something isn't adding up right.

    3. Check Device Manager

    In Device Manager, I checked on the eXtensible Host Controller that you see mentioned above as the cause of the last wake event. There's only one such controller:

    And the device properties:

    As you can see, according to device manager properties, the device isn't allowed to wake up the computer - and yet it did.

    And remember how it said that the Plugable ethernet was wake_armed? Well check this out:

    4. Check Event Viewer

    Event viewer confirms the eXtensible host controller as the cause of the wake event:

    The system has returned from a low power state.

    Sleep Time: ‎2021‎-‎03‎-‎25T21:37:43.268198000Z
    Wake Time: ‎2021‎-‎03‎-‎25T22:46:01.919720100Z

    Wake Source: Device -Intel(R) USB 3.1 eXtensible Host Controller - 1.10 (Microsoft)
    Summary

    1. In power settings, wake from sleep is disabled entirely.
    2. The system is being woke by a device that, in device manager, shows isn't even allowed to wake up the computer.
    3. Another device (plugable ethernet) shows in powercfg that it is wake_armed, even though its power configuration in device manager says the opposite.

    Something crazy is going on here. How do I stop this computer from waking up?

    :)

  2. Troubleshooting PCs spontaneously waking from sleep

    I've also battled with sleep/wake issues over the years, and from experience have learned that trying to find, or rationalise, the root cause is a waste of time. All you need is `powercfg`.

    `powercfg -devicequery wake_armed` from an Administrator PowerShell window/Command Prompt will give you a list of all devices that can possibly wake the PC. This command is interesting because very often, it will show devices that you'd never expect being able to wake your computer. I think in one instance I had the chipset device listed!

    `powercfg -devicedisablewake "device_name_from_device_query"`will prevent said device from ever waking the computer. This command is 100% the only thing I have found that will resolve sleep/wake problems. Updating drivers, unplugging peripherals, switching to a cleaner power supply (UPS), changing ethernet cables... none of those have helped, yet`powercfg -devicedisablewake` has done the trick.

    Note that occasionally, devices you have disabled wake for may start waking up the PC again - this happens if you plug a USB device into a different port, or occasionally when drivers are updated, because Windows sees it as a new device. In that case rerun `powercfg` to find and disable that device again.

    If this does not resolve your wake issues, I would start looking at power fluctuations.
