Similarly, you can create a task such as sleep mode by entering “Program or script:” in the line:
C:\Windows\System32\rundll32.exe powrprof.dll,SetSuspendState Sleep
If you want to delete it, in the Task Scheduler window on the left click “Job Scheduler Library” and clicking the right button on the desired task, click “Delete”.
