Windows has a tool that allows predefined tasks or actions to be executed within a certain set of conditions, for example, running a backup script, showing a message box, or sending an email when a system event happens.

This tool is called Task Scheduler. It also lets you perform certain routine tasks automatically on your computer, by monitoring your chose criteria to initiate these tasks (or triggers), then executing them based on the criteria.

Some of the tasks it can execute include when the computer enters idle state, when a task is registered or the system booted, at a specific time on daily/weekly/monthly schedule (or monthly day-of-the-week schedule), or when you log in.

But what happens when Task Scheduler won’t wake up the computer?

When this happens, it could be that you use the Create Basic Task Wizard to create a scheduled task, so the functionality to wake your computer to run a scheduled task isn’t considered a basic one.

Other times it may be caused by conflicts previously with the Task Scheduler such that it couldn’t initiate the scheduled task and thus unable to wake up the computer. Alternatively, it could be that Windows reverted a setting to disable sleep/wake timers in the OS, or Windows has a bug in it (or updated a driver with a bug), or there’s a device attached to your PC that prevents sleep/wake timers.

Whatever the case may be, we’ve got solutions to help you work around the issue.

FIX: Task Scheduler won’t wake up computer

  1. Create a new task
  2. Enable hybrid sleep
  3. Create a new user profile with admin rights
  4. Reset and restore power plans to default
  5. Set the computer to wake up and run a task
  6. Check your graphics card driver and enable Hibernation
  7. Use a command line

Solution 1: Create a new task

If you’ve updated all your drivers, tried restarting, or even disabled third party apps and Task scheduler still won’t wake up your computer, try creating a new task and then set appropriate settings in the condition tab of the schedule task windows and see if it helps.

Solution 2: Enable hybrid sleep

  • Click Start and select Control Panel
  • Go to Hardware and Sound

  • Select Family and Other people

  • Click Add someone else to this PC

  • Fill in the form with the user name and password. Your new user account will be created.
  • Click on Change account type
  • Click the drop down arrow and choose Administrator to set the account to administrator level
  • Restart your computer

Login to the new account you just created and set Task Scheduler.

Solution 4: Reset and restore power plans to default

  • Go to the search bar and type CMD
  • Right click on Command Prompt and select Run as administrator

  • Type powercfg –restoredefaultschemes and press Enter
  • Exit the command prompt

This will reset the power plan settings to default so any customized power plans will be removed.

Solution 5: Set the computer to wake up and run a task

  • Go to the search bar and type task scheduler then press enter
  • On the right pane, select Create Task

Task Scheduler won’t wake up computer

  • Go to General tab and fill Name and Description

  • Check the box Run with highest privileges

  • Go to Triggers tab and click New

  • In the new window, select One Time (set the date and time you want your system to wake from sleep)

  • Go to Actions tab and mention a task then click New

  • Select Action as: Start a program. If you want to schedule a task that executes cmd.exe command with command line arguments, copy-paste under Program/script/c “exit”

  • Go to Conditions tab and check the box Wake the computer to run this task. Click OK and exit task scheduler.

Task Scheduler won’t wake up computer

Your computer will wake up from sleep at the time you set it to.

Solution 6: Check your graphics card driver and enable Hibernation

Ensure your graphics card is using an OEM driver as the Microsoft Basic Display driver won’t allow sleep function to work. Windows 10 fully supports hibernation, which works sometimes when sleep won’t work. So do the following to enable hibernation:

  • Go to the search bar and type CMD
  • Right click on Command Prompt and select Run as administrator

Task Scheduler won’t wake up computer

  • Type the command powercfg –h on and press enter
  • Go to Control Panel and click Hardware and Sound then select Power Options

Task Scheduler won’t wake up computer

  • Click Choose what the power buttons do

Task Scheduler won’t wake up computer

  • Click Change settings that are currently unavailable

Task Scheduler won’t wake up computer

  • Scroll down and tick Hibernate then click Save changes
  • Click Start>Power>Hibernate to test the new feature

Note: if hibernate is missing, then your computer has a driver issue preventing it from using low power states.

Solution 7: Use a command line

If you want to put your computer to sleep via command line, install a more capable tool then copy the PsShutdown.exe to your desktop.

  • On your desktop, right click exe and click Copy, then right click again and click Properties. Tick Unblock and press OK.
  • Open File Explorer, go to local C:\Windows then right click on system32 folder and click paste. You can use the following command to enter standby mode: psshutdown –d –t 0
