The ac adapter might heat up. For optimal performance use the ac adapter that came with the dell laptop pc. The ac adapter s wattage information is printed on the bottom of the ac adapter.

Any displacement of that pin can break the circuit and cause the adapter to be unrecognized. To verify if the pc is recognizing the ac adapter correctly. The ac power adapter type cannot be determined. Your system will operate slower and the battery will not charge.
