[ltp] self-made external battery for laptops project

[peter nol]

I will probably have to consult a friend /an electrical engineer/ about this.
two options come immediately to my head- use two contacts ignoring the other 
two-
Try spoofing voltage by a small current across the other too
Should probably use a tester/multimeter /my knowledge of electrical 
engineering is minimal/
Too bad that IBM isn't more open about their hardware specs. I searched 
extensively through spec sheets and the web- alas, without insider knowledge 
it's an abyss. 
Shure hope i'm wrong
