Scheduling an automatic power on and off in Ubuntu Linux can be done using various tools and commands. Here’s a concise guide in tabular format:

1. Open terminal. <br> 2. Type crontab -e to edit the cron jobs. <br> 3. Add a new line in the format: MIN HOUR * * * /sbin/shutdown -h now (replace MIN and HOUR with your desired time). |
| Automatic Power On | BIOS/UEFI settings | 1. Reboot your system and enter the BIOS/UEFI settings (usually by pressing F2, F10, DEL, or ESC during boot). <br> 2. Look for a power management section. <br> 3. Set the automatic power on time if available. <br> Note: Not all systems support this feature. |
Additional Notes:
- Automatic Power Off: The
cronjob runs theshutdowncommand at a specified time. You can set this for daily, weekly, or monthly power-offs. - Automatic Power On: This is dependent on your computer’s hardware and might not be available on all systems. Check your system’s manual for more details.
- Time Format in Cron: The time format in a cron job is in 24-hour format. For example, to shut down the computer at 10 PM every day, you would write
0 22 * * * /sbin/shutdown -h now. - Editing Cron Jobs: Ensure you’re careful while editing cron jobs. Incorrect entries can affect system behavior.
- Saving Cron Jobs: After adding the cron job, save and exit the editor. The cron daemon will automatically pick up the new job.
- System Compatibility: Check if your system’s BIOS/UEFI supports scheduled power ons, as this feature is not universally available.
Remember that scheduling a power on requires BIOS/UEFI support and may not work on all machines. The scheduled power off, however, will work on any system running Ubuntu Linux.
