Mini PC Auto Power-On After Power Failure: Setup Guide & Qotom Models

For industrial automation, remote monitoring, and network applications, unexpected power outages can interrupt important operations.

A mini PC with Auto Power-On After Power Failure can restart automatically when electricity returns, reducing the need for manual intervention.

Qotom offers industrial mini PCs with automatic power-on capabilities, watchdog timers, and multiple connectivity options for unattended deployments.

1. What Is Auto Power-On?

Auto Power-On, also known as AC Power Recovery, allows a mini PC to restart when power is restored after an outage.

Depending on the hardware, this function may be controlled through BIOS settings or an onboard auto-start jumper.

Common BIOS options include:

• Power On: Automatically starts when power returns.

• Power Off: Remains powered off.

• Last State: Attempts to restore the previous power state.

This feature is particularly useful for systems installed in remote locations or operating without dedicated personnel.

2. How to Enable Auto Power-On on a Mini PC

The setup procedure depends on the motherboard and BIOS version.

Step 1: Enter BIOS setup during startup, typically using Del or F2.

Step 2: Look for a setting such as Restore on AC Power Loss, AC Power Recovery, or State After G3.

Step 3: Select Power On, save the settings, and restart.

Step 4: Perform a controlled power interruption test to confirm automatic startup.

Some Qotom mini PCs also feature a dedicated AutoStart Jumper for hardware-level power-on configuration.

Always check the model-specific documentation before changing jumper positions.

3. Qotom Mini PCs with Auto Power-On Support

Qotom provides several industrial and multi-LAN mini PCs with documented auto-start jumpers and watchdog support.

Q30900P-S08 — Industrial mini PC with 4×RS-232 serial ports, 2×2.5GbE LAN, and Intel 8th–10th Gen U-series processor options. Suitable for industrial control and equipment monitoring.

Q10800XPGV-S04 — Embedded mini PC with Intel Elkhart Lake processor options, 5×RS-232 ports, and dual Gigabit LAN. Designed for serial-device integration and industrial automation.

Q10900H6-S13 — Compact network appliance with 4×2.5GbE and 2×10GbE RJ45 ports. Suitable for network security and unattended networking applications.

Q10900S6-S13 — Multi-LAN mini PC featuring 2×2.5GbE, 2×10GbE RJ45, and 2×10GbE SFP+ ports for flexible high-speed networking.

Q71200G6-S18 — Six-port 2.5GbE mini PC with Intel Core processor options and up to 64GB DDR4 memory. Suitable for demanding network and edge computing workloads.

All five models list AutoStart Jumper and Watchdog support in their official specifications. Configuration details may vary by hardware revision.

4. Auto Power-On vs Watchdog Timer

Although both features improve system availability, they serve different purposes.

Auto Power-On helps a mini PC restart after external power is restored.

Watchdog Timer can trigger a system reset when properly configured software stops responding.

For unattended industrial applications, combining these features with automatic application startup and appropriate backup power can improve operational reliability.

Conclusion

Automatic power recovery is an important consideration when selecting a mini PC for 24/7 or unattended operation.

From multi-serial industrial computers to high-speed network appliances, Qotom offers multiple hardware options with documented auto-start support.

Choosing the right model depends on your required interfaces, processor performance, and deployment environment.
