hi
You need to connect the middle needle of the adapter head to a voltage of 19 volts using a resistor, the size of which depends on what adapter you want to simulate. In each hp adapter with different power, the size of this resistor is different. You can achieve this by measuring the ohmic middle needle of the adapter plug in a healthy adapter.

I'm sorry for the delay
