Open the case and find the CMOS battery on the motherboard.
Use an appropriate tool to remove the CMOS battery and leave it for a while to allow the motherboard's charge to be completely exhausted.
Reinsert the CMOS battery into the slot and install the case cover.
Reconnect the power cord and turn on the computer.
Observe the operation of the CPU fan. If the problem persists, continue to try other solutions.

3. Check the 24-pin power connection terminal
Turn off the power of the industrial computer such as rugged fanless mini pc and disconnect the power cord.
Open the case and find the 24-pin power connection terminal on the motherboard.
