WakeMyPotato

WakeMyPotato (WMP) is a straightforward yet effective systemd service designed specifically for aging Linux laptops that may face challenges during power outages. This utility aims to provide a solution for machines that lack Wake-On-Lan (WOL) support or automatic BIOS boot timers, offering users a way to keep their old devices operational even in times of power failure.

In essence, WakeMyPotato configures automatic rtcwake commands to manage system power efficiently. When AC power is lost, the service ensures safe shutdown procedures, including power-off measures for RAID HDDs if present, preventing mechanical wear. Upon restoration of power, WMP attempts to boot the system automatically after a predetermined waiting period, which can be configured by the user. While the default wait time is set to 600 seconds (10 minutes), this can be adjusted according to specific needs.

Key Features:

• Automatically prepares the system for power disruptions with safe shutdown protocols.
• Attempts to revive the system post power restoration without the need for manual intervention.
• Last-resort option for devices lacking WOL or automatic BIOS waking capabilities.

Usage Commands:
The service provides a user-friendly command interface, allowing for a range of functionalities. Below are some of the key commands available:

Command	Description
sudo wmp help	Lists all available commands
sudo wmp version	Displays the software version
sudo wmp status	Checks the current service status
sudo wmp log	Views recent warning logs
sudo wmp set <seconds>	Adjusts configuration settings
sudo wmp run <seconds>	Executes a manual check
sudo wmp stop	Stops the service
sudo wmp start	Initiates the service

In summary, WakeMyPotato serves as a valuable tool for repurposing older laptop hardware into functional home servers, ensuring they remain operational and ready for use after power interruptions.
