Laptop wakes up with lid closed - powercfg is no help

Hi, from the huge searchable Tutorial section (do have a look) I found:
See Wake Source in Windows 10
View Wake Timers in Windows 10
See Devices able to Wake Computer in Windows 10

These may help you...

Is your PC networked when it wakes, or completely isolated?

Could it be waking for maintenance or an update? (Check your Update History)
What does it do when it wakes?

To consider:
Laptop wakes from sleep - help!
Laptop wakes from sleep - help!

History: (so often omitted by posters):
When was the last time you knew this didn't happen?

Tony,

From which state is it waking?
Do you have mains power connected at the time?

To make sure your potential power states are understood, run this command and post the results

Code:

PowerCfg -a

The results of interest are
- - whether you have S3 Sleep or S0 Modern standby [aka S0 Low power idle], and
- - if you have Hibernate enabled.


Event logs can reveal more info than -lastwake can.
- You can import an Event viewer, Custom definition that shows you the transitions between power states.
- I can explain how to import such a Custom view.
- You can then find examples of resuming and see what the General tab of the event says was the cause.


Here is the [zipped] definition for that Event viewer, Custom view.
Power - Sleep-Hibernate-S0 transitions.zip
Before importing it, you can read its unzipped xml files in Notepad or, for a better presentation of its contents, by right-clicking and opening in a browser.
I use this combined Custom view for all my computers. If you have S0 then its transitions are presented & if you have S3 Sleep then its transitions are presented.

To import it:
1 Unzip the file
2 Open Event viewer, click on Import Custom view [on the right-hand side],
3 Browse to and select the xml, Open,
4 Change the name if you want to then OK,
5 You can see the records, on the left-hand side, within the group Custom views.

You can then select this Custom view in Event viewer's left-hand pane.

When reviewing power state transitions, note that S3 Sleep & Hibernation events can only be distinguished, in a computer that has both, by looking at the Details tab of the resume EventID 1 for Hiber* entries that are greater than 0; resuming from S3 Sleep would show Hiber* entries that have the value 0
Resume from Hibernate, Details tab

Resume from S3 Sleep, Details tab



On a similarly confusing note, S0 Modern standby event records are misleadingly labelled as relating to S0 Connected standby whichever state is in force - Connected/Disconnected standby.



Best of luck,
Denis

Tony,

You were probably already writing your post when I posted.

Please don't miss my post. Understanding these factors is essential:-

Some of your observations make me think that you have S0 Modern standby in which case your computer does not sleep in the sense that the term has come to be used.
- S0 is just a glorified idle condition.
- S3 Sleep is what people generally mean when they use the term sleep.


All the best,
Denis

It would be worth disabling wake timers at least as an experiment...

Your computer does not sleep. You have S0 instead and it is not the same as sleep.
Your computer is merely idling and that's why the fan can come on.

There are, in effect, four Power/Computer states for an S0 Modern standby [aka S0 Low power idle] computer
- Computer on, Monitor on {Work can be done on the computer}
- Computer on, Monitor off = S0 {The monitor turning off initiates S0 Modern standby i.e. idle}. S0 progressively inhibits user-initiated processes. No user-desired activities start, only MS-desired ones such as WU & their built-in email app.
- Hibernate
- Off

I went through several different stages in my approach to S0:-
- I adapted to S0 by using hibernation when I had been used to using S3 Sleep.
- When I got even more fed up with S0, I set my monitor to always stay on [it's the monitor turning off, as set in Power options, that starts S0] and I set a very dark screensaver to come on after a desired time so the screen wouldn't be staring at me all day.
- Eventually, I just used the tutorial to disable S0. And I would never even think about re-enabling it.
Disable Modern Standby in Windows 10 and Windows 11 - ElevenForumTutorials

- - Many people have found that disabling S0 automatically enabled S3 Sleep.
- - In my case, S3 Sleep remained disabled so I carried on having to use hibernation as a second-best choice.

- - In my case, Task scheduler would not wake the computer from hibernation but others have reported that theirs worked OK.

- - In my case, my WiFi adapter often sometimes fails to restart properly [no networks detected] when it comes out of hibernation so I run a little script to disable it then re-enable it after which it works again.

All the best,
Denis

Found the tutorial and indeed I think I'm ok with S3.

I think you are saying that you've now disabled S0 and that S3 is enabled as a result.
You won't regret it.
You can confirm your new power states by re-running that PowerCfg -a command.

S0 seems a bit stupid

That is a very polite comment.
Other polite comments include, "It's a curse".
But it does suit some people.


All the best,
And thanks for the rep,
Denis
