Outer shielding = ground
middle shielding = +19V
white = AC adaptor ID.

The AC adaptor ID wire is for communication between the laptop and the power supply to make sure it can supply enough power and to make sure it is a Dell power pack. The laptop will not charge without this AC adaptor ID wire connected. The system performance is also decreased if a non Dell supply is used (or if the white wire is not connected).

Hope this helps
