Computer turns on on its own.

Shane Ptach 0

Specifications are

Windows 11 Home

24H2

11/‎23/‎2024

26100.8457

Windows Feature Experience Pack 1000.26100.304.0

Brand is Cyberpower, and for one last piece of intel is my mouse has always been lightly jittery, moving on its own, when the computer is on, but this has only been when it's on and is a problem it has had since I bought it back in fall of 2024. My PC is turning itself back on after I put it to sleep. I checked for viruses, nothing. I did download mods for Fallout New Vegas the night before, got them working around noon today. Problem only started after I stopped playing around five thirty. Additionally, I performed two updates for windows today catching up on old updates. I even performed checks to see what is waking it up only for it to say keyboard, despite my experimenting with unplugging both the keyboard and mouse immediately after putting the computer to sleep. I have even tried turning the computer fully off and back on to no avail. I'd like a solution soon as to make sure my computer isn't costing power for my family.

Hi Shane Ptach,

Since you have already checked the usual wake reports, the next step is to narrow down whether this is being triggered by a background program or by a firmware/device wake setting.

Microsoft’s clean boot process may help isolate third-party software, please try these steps to test in a clean boot:

Press Win + R, type msconfig, and press Enter.
On the Services tab, check Hide all Microsoft services > select Disable all.
Open Task Manager from the Startup tab and disable startup apps.
Restart the PC and test Sleep again.
If the issue stops, a background app or service is likely involved.

You can also check BIOS/UEFI wake settings

Go to Settings > System > Recovery > Advanced startup > Restart now.
Open UEFI Firmware Settings.
Look for options such as Wake on LAN, Power on by USB, Wake by keyboard/mouse, or RTC/Alarm wake, and disable them for testing if available.

If you need the PC to stay off overnight while testing, use Hibernate instead of Sleep. Hibernate uses less power than Sleep and is a good temporary option while troubleshooting.

If the PC still powers back on after a clean boot and firmware check, the next best step would be to contact CyberPower or the motherboard manufacturer for BIOS-level guidance, since wake behavior can sometimes be managed outside Windows.

I hope this helps you narrow it down and get the system staying asleep as expected. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.

Thank you for the information, but sadly it doesn't look like this helped. To think all this started because of some windows updates that I've tried but can't revert. I've talked with other tech adept people, and it seems that sleep mode being broken is an issue that's only gotten worse with updates since January due to the use of AI in coding the updates. I can only hope that the corporate execs learn from this and leave coding to the programmers and not an AI that will forget what it did in a week. If possible, can you put in a word with the executives to help them understand how many people this is affecting?

Hi Shane Ptach,

I understand why you’re frustrated, especially when the issue started after updates and the earlier steps did not improve the behavior.

Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. I’m not able to directly pass comments to Microsoft executives from here, but the most effective way to make sure this is formally captured is through Feedback Hub. You can also attach screenshots or diagnostic details to help document the problem clearly - press Win + F to open Feedback Hub directly or you can also use the Get Help app.

I know this has been a draining issue to chase down, but submitting feedback is the best channel to show how widely it is affecting people.

The behavior is consistent with Windows wake timers and hardware wake sources bringing the PC out of sleep, not with malware or Fallout mods.

Use these steps to identify and stop the wake source:

Check what last woke the PC
1. Put the PC to sleep and let it wake by itself.
2. After it wakes, open an elevated Command Prompt (Run as administrator).
3. Run:
```
      powercfg /lastwake
```
  This shows which device or timer last woke the system (for example, keyboard, mouse, or a scheduled task).
Check scheduled wake timers
1. In the same elevated Command Prompt, run:
```
      powercfg /waketimers
```
  If a task such as Regular Maintenance or Windows Update is listed, it is allowed to wake the PC for maintenance.
2. The article in the context shows that Windows maintenance tasks (for example, Windows Update or .NET NGEN) can schedule wake timers so the PC wakes around 3:00 AM to run “Regular Maintenance”. This is logged as a wake timer created by services.exe and a Task Scheduler maintenance event.
Disable wake timers in the active power plan
1. Open Settings → System → Power & battery → Additional power settings (or Control Panel → Power Options).
2. Next to the active plan, select “Change plan settings” → “Change advanced power settings”.
3. Expand “Sleep” → “Allow wake timers”.
4. Set both “On battery” (if present) and “Plugged in” to “Disable”.
5. Apply and OK. This prevents scheduled maintenance tasks (like Windows Update maintenance) from waking the PC.
Disable device wake (keyboard/mouse) if needed Since powercfg /lastwake reports the keyboard, and the mouse is jittery, either device can generate spurious wake events.
1. Open Device Manager.
2. For the keyboard and mouse devices (including any HID-compliant mouse/keyboard entries):
  - Right-click → Properties → Power Management.
  - Clear “Allow this device to wake the computer”.
3. If the system supports presence sensors (Wake on Approach) and they are enabled, they can also wake the PC from Modern Standby or S3 (depending on Windows 11 build and configuration). If present, disable presence-based wake in the OEM’s or Windows’ power/presence settings.
Check Task Scheduler maintenance tasks
1. Open Task Scheduler.
2. Navigate to Task Scheduler Library → Microsoft → Windows → TaskScheduler.
3. Look for “Regular Maintenance” and related tasks.
4. In task properties → Conditions, clear “Wake the computer to run this task” for tasks that are not needed to wake the PC.
Review for Modern Standby / presence-sensing behavior The “Wake on approach” feature (presence sensing) can wake devices from Modern Standby and, on newer Windows 11 builds, from S3 if the device is armed for wake. If the device is frequently waking unexpectedly and battery drain or unwanted wake is a concern, presence-based wake should be disabled until the power behavior is tuned.

After these changes, repeat the sleep test. If the PC no longer wakes on its own, the cause was either a wake timer (maintenance/Windows Update) or a device wake (keyboard/mouse/presence sensor).
