Re: Generic Laptop power brick



You are right. I ripped one 170w power to my other project and took a picture of the connector.
The resistor is 1.5k ohm.
65w and 90w power supplys have 10k ohm resistor when measuring center pin against gnd.
Resistor just tells to the laptop what kind of charger is connected.

Here is picture of 170w connector.
