Step 6: Power On the Motherboard

Use a DC power supply or power cable to boot the motherboard.

The tool will begin capturing serial logs automatically.

Step 7: Analyze the Error Logs

Once logs appear, click Analyze.

The cloud AI compares the log data with thousands of motherboard repair cases and detects possible hardware faults.

This saves time and improves diagnosis accuracy.
