The "Power LED" indicates the system is running, and the "HDD LED" shows disk activity. Configure the corresponding LED triggers accordingly. Caveats: - The LEDs are driven through a 4.7k series resistor, making them quite faint. - The disk activity trigger requires a storage controller on the M.2 or PCIe interface. That said, it matches the purpose and the vendor kernel.
