Windows 10: Lenovo Legion 5 wakes from Sleep even after disabling waking

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.

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?

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.

Stay in sleep and wake with spacebar

Hi, you can disable hibernation if you wish:

This depends what devices are able to wake your PC. You can list these:

Powercfg /devicequery /.......
Description:
Returns a list of devices that meet the specified criteria.

Parameter List:
<QUERYFLAG> Specifies one of the following criteria:

wake_from_S1_supported ....Return all devices that support waking the system
from a light sleep state.
wake_from_S2_supported ....Return all devices that support waking the system
from a deeper sleep state.
wake_from_S3_supported ....Return all devices that support waking the system
from the deepest sleep state.
wake_from_any ......................Return all devices that support waking the system
from any sleep state.
S1_supported List devices supporting light sleep.
S2_supported List devices supporting deeper sleep.
S3_supported List devices supporting deepest sleep.
S4_supported List devices supporting hibernation.
wake_programmable List devices that are user-configurable to wake
the system from a sleep state.
wake_armed List devices that are currently configured to
wake the system from any sleep state.
all_devices Return all devices present in the system.

Examples:
POWERCFG /DEVICEQUERY wake_armed
