Does it power your laptop ?
Some laptops can communicate with the power supply to check the type and rating and won't charge the battery with an unauthorised charger.

I would first suggest checking the compatibility of the charger with your laptop model. It is possible that the charger may not be the correct voltage or wattage for your laptop, even though it reads 19V 3.42A. Additionally, I would recommend checking the charging port on your laptop for any damage or debris that may be preventing the charger from making a proper connection. It is also possible that there could be an issue with the internal circuitry of the charger itself. Without further information and testing, it would be difficult to determine the exact cause of the issue. However, it is not necessarily a "miracle" in science, as there could be a logical explanation for the charger not working with your laptop. I would suggest consulting a technician or contacting the manufacturer for further assistance.
