If you want your Windows computer to wake up automatically at a specific time to perform a task, you can achieve this using a batch script in conjunction with the Task Scheduler. Below, we will discuss how to create a Task Scheduler entry that includes a condition to wake the computer from sleep. We will also provide an example of the batch script necessary to achieve this functionality.
Problem Scenario
You need to schedule a task that wakes your Windows computer from sleep mode to execute a specific command. However, you are unsure how to create a Task Scheduler entry with a wake computer condition using a batch script. Below is a basic code snippet that may lead to confusion:
schtasks /create /tn "MyTask" /tr "C:\Path\to\your\script.bat" /sc daily /st 09:00
Improved Code and Explanation
Here’s a clearer version of the command, including the wake condition:
schtasks /create /tn "MyTask" /tr "C:\Path\to\your\script.bat" /sc daily /st 09:00 /RL HIGHEST /RU SYSTEM /Z /IT
Breakdown of the Command:
/create: This option is used to create a new scheduled task./tn "MyTask": Specifies the name of the task./tr "C:\Path\to\your\script.bat": This defines the task's action—in this case, executing a batch script./sc daily: Sets the schedule type to daily./st 09:00: Specifies the start time for the task (9 AM)./RL HIGHEST: Runs the task with the highest privileges./RU SYSTEM: Runs the task under the SYSTEM account, which has higher privileges./Z: Indicates that the task should be deleted if the task no longer exists./IT: Allows the task to run interactively when the user is logged in.
Additional Considerations
When you create a task that has the wake condition, ensure that your computer's power settings allow it to wake from sleep for scheduled tasks. To check or adjust these settings:
- Go to Control Panel > Hardware and Sound > Power Options.
- Click on Change plan settings next to your selected plan.
- Choose Change advanced power settings.
- Expand Sleep and ensure that Allow wake timers is enabled.
Practical Example
Let’s consider an example where you want your computer to run a backup script daily at 10:00 PM.
- Create a batch script called
backup.batthat performs the backup operation. - Save this script in
C:\Scripts. - Use the following command to schedule the task:
schtasks /create /tn "DailyBackup" /tr "C:\Scripts\backup.bat" /sc daily /st 22:00 /RL HIGHEST /RU SYSTEM /Z /IT
