Auto reboot if PC is on Idle for 30 minutes

Is your PC often left running without any tasks being performed? Are you concerned about energy consumption or system performance when you step away from your workstation? One effective solution is to configure your computer to automatically reboot after 30 minutes of inactivity. This article will guide you through the process while providing insights and additional tips to optimize your setup.

Understanding the Problem

Many users face situations where their PCs are left idle for long periods. This may result in unnecessary energy consumption and potential software hiccups. You may have tried to write a script to handle this task, but if your initial attempt was unclear, it could lead to confusion. Here’s a simple example of what the initial approach might look like:

if idle for 30 minutes
then
    reboot
fi

Revised Script Example

The above code is not easily understandable and lacks clarity. A more structured approach would look like this:

#!/bin/bash

# Define idle time limit
IDLE_TIME=1800  # 30 minutes in seconds

# Get idle time in seconds
idle_seconds=$(xprintidle)

# Check if idle time exceeds 30 minutes
if [ "$idle_seconds" -gt "$IDLE_TIME" ]; then
    echo "System is idle for more than 30 minutes. Rebooting..."
    sudo reboot
fi

In this script:

We set an idle time limit of 1800 seconds (30 minutes).
The xprintidle command checks for idle time.
If the idle time exceeds 30 minutes, the system will proceed to reboot.

How to Implement Auto Reboot

Create the Script: Save the revised script in a file, for example auto_reboot.sh.
Make the Script Executable: Open your terminal and run:
```
chmod +x auto_reboot.sh
```
Schedule the Script: You can set this script to run at intervals using cron. Open the crontab editor by typing:
```
crontab -e
```
Add a line to check every minute:
```
* * * * * /path/to/your/auto_reboot.sh
```
Test the Functionality: Leave your computer idle and observe if it reboots after 30 minutes.

Benefits of Auto Rebooting

Energy Efficiency: Reducing power consumption by shutting down devices when not in use.
Performance Improvement: Clearing memory and releasing resources can lead to better system performance upon reboot.
Prevent System Hang-ups: Regular reboots can prevent your system from freezing or crashing.

Potential Drawbacks

While automating reboots can be beneficial, consider these aspects:

Loss of Unsaved Work: Users may unintentionally lose open documents or unsaved work.
Interruption of Scheduled Tasks: Running processes may be interrupted, which could be detrimental to tasks that need to finish.

Additional Tips

Notification Alerts: Consider implementing notification alerts before the reboot to avoid losing data.
Adjust Idle Time: Modify the idle time as per your convenience; it doesn’t always have to be 30 minutes.

Conclusion

Setting your PC to reboot automatically after being idle for 30 minutes can enhance your computing experience, save energy, and prevent unnecessary system slowdowns. By following the steps outlined above and customizing the script to suit your needs, you can ensure your system remains efficient and well-maintained.
