To launch the utility, go to Windows 10 settings. Under the  Update & Security section, click Troubleshoot.

Update & Security section

To display the Power Troubleshooter, expand the menu with  Additional Troubleshoot Utilities.

Prevent Windows from waking up unintentionally.

Now that we have identified the source of your Windows 10 PC sleeping problem.

It’s time to fix it.

In this section, we will explain the different solutions available to you.

Disable waking up by a device

If it is a peripheral, mouse, keyboard, or network card, for example, which wakes up your PC, you must remove this right from it. To do this, open  Device Manager.

In the panel of devices, find the device causing the problem—Right-click on it and click  Properties.

Among the tabs, open the Power Management tab.

Then uncheck the  Allow this device to wake the computer from sleep mode.

This device will then no longer be able to wake the computer from sleep.

Delete an automatic task

To delete or deactivate a task that wakes your PC from sleep, you must open the  Task Scheduler.

Task Scheduler

Once the scheduler is open, find the task that caused your PC to wake up.

Right-click on it and click  Properties.

Once in the task’s properties, under the Conditions tab,

uncheck the  Wake the computer from sleep mode to run this task check box.

Prevent programmed actions from waking the device from sleep

Open Power Options from Control Panel or taskbar as below.

In the power options, locate the active power plan and click  Change mode settings.

Then click on  Change advanced power settings.

Go down in the settings, then under the Standby level,

in  Allow wakeup timers, check that both options are on  Disable.

Prevent automatic maintenance from waking the PC from sleep

Automatic maintenance can also force your PC to wake up from its sleep. To check this setting, we will go to the control panel.

Now find the Security and Maintenance section.

Expand the Maintenance part.

Click  Change maintenance settings.

All that remains is to uncheck the Allow scheduled maintenance box to interrupt my computer’s sleep at the scheduled time.

Conclusion

Sometimes a computer will start so slowly that even the wisest people cannot get it going. A poor program installation will make your computer so slow that it will take forever to start up and shut down properly.

To solve this problem, you can either try to reinstall the program or update the program. Reinstalling the program will usually fix the issues, but you may need to update it if it doesn’t work.


The last thing that can cause your system to wake up from sleep is a virus or Trojans. If you think that you’ve gotten a virus, you should immediately download a good system recovery program and use it to clean up any infections that are on your computer.

This will make your computer normally run again and hopefully, and it will stop all the errors that are causing the problems.
