This guide demonstrates how to configure the Auto Power On function in BIOS for X86 motherboards. Once enabled, the industrial PC will automatically power up when power is restored after a power outage. This feature is widely used in unattended applications including kiosks, industrial control terminals and monitoring equipment.
