SUMMARY
The discussion centers on a 19V 3.42A laptop charger that fails to charge a laptop despite showing continuity and the correct voltage output. It is established that some laptops have built-in communication protocols that verify the charger’s specifications and may refuse to charge if the charger is unauthorized or incompatible. This indicates that not all chargers, even if they provide the correct voltage, are suitable for every laptop model.
