1. Check the polarity of the adapter

Make sure the positive and negative poles of the industrial computer adapter are connected correctly.

Check the plug of the adapter and the jack of the industrial computer to ensure that the positive pole is connected to the positive pole and the negative pole is connected to the negative pole.

If the positive and negative poles are connected in reverse, it may cause a short circuit, which will affect the normal power supply of the industrial computer. It is recommended to re-plug the adapter and ensure the correct connection.

2. Measure the adapter output voltage

Use a multimeter or similar instrument to adjust the measurement range to the adapter output voltage range.

Connect the positive and negative poles of the adapter to the positive and negative poles of the multimeter.

Turn on the adapter power and measure the output voltage.

Check whether the measurement result matches the output voltage marked on the adapter.

If the output voltage is abnormal or zero, it may indicate that the adapter is faulty and it is recommended to replace the adapter.

3. Check the output of the power cord

Use a multimeter or similar instrument to adjust the measurement range to the range of AC voltage.

Insert the probe of the multimeter into the plug hole of the power cord.

Plug the power cord into the power socket and turn on the power switch.

Check whether the voltage value displayed by the multimeter is close to 220V (or the standard voltage value in the area).

If there is no voltage output or the display is abnormal, it may indicate that the power cord is faulty. It is recommended to repair or replace the power cord.

4. Seek help

If the above methods cannot solve the problem, there may be other faults or damage. In this case, it is recommended to contact the equipment manufacturer or after-sales service center for more professional technical support and repair services to help solve the problem.

5. Conclusion

In short, when the industrial computer cannot be powered on, the failure of the adapter and power cord is a common problem. By carefully checking the polarity of the adapter, measuring the output voltage of the adapter, and checking the output of the power cord, you can better troubleshoot and solve the problem.
