Hi, I want to be able to run my Dell Inspiron 600m using a custom-made
external 18V battery pack at next year's Burning Man. And I can do
this, but the internal battery will not charge from it without that
3rd, inner conductor of the triaxial cable carrying some unknown
signal. I don't have an oscilloscope any more, and would rather not
have to buy one. Has anyone hacked into this and knows what's being
sent over that 3rd conductor, so I can rig a circuit to emulate it?
Googled and found nothing. Thanks -- jc
