On a laptop power jack,
The center pin senses/communicates something; is it
- for the power adapter to sense some feedback from a laptop or
- for the laptop to sense something from the power adapter
- or both ?
And what is the protocol/architecture/voltages of such 'data' pin under varied conditions ?
----> **broken link removed**
My Compaq has it, and most HP/CQ too
