Who keeps waking up on the sleeping computer? Such a check will know

In the Windows system, if the power management related options are not set properly, there will be a lot of strange problems, such as hibernation/sleep abnormality, being waken up in sleep/sleep state for no reason. These are better on the desktop. If everyone's notebook is not carefully adjusted, then unconsciously increase the battery consumption, the boot power warning is not fun.

So the most intuitive way to see which hardware devices can wake up our computer is to enter at the command prompt.

Powercfg -devicequery wake_armed

Command to show which hardware devices in the current computer can wake the computer. Or use

Powercfg -lastwake

Check which hardware booted/woke up the computer.

If it is our manual operation to see if it is not, then you can find the hardware in the device manager, in the properties of the power management tab, remove the "Allow this device to wake the computer" check.

Well, apart from the computer's conventional hardware that can make the computer "wake up", Windows' own system services, scheduled tasks, and our own installed third-party software may also cause the computer to wake up at an inappropriate time. But this can't be found in the command prompt. You need to borrow the power of PowerShell.

After typing Windows PowerShell, enter

Get-ScheduledTask | where {$_.settings.waketorun}

In the displayed list, see what software is under "State" and the service is in the state of Running and Ready.

Do not want computers to be awakened by them go to "Control Panel - Management Tools" in the "scheduled tasks" and "services" in their name after the search to close off OK.
