Solved! Wiring for dell laptop1526

[CoolB4]

I broke the one and only black wire under the central control panel (where power panel) One end comes out of the MB but I cannot figure out where the other end goes. The computer is just dead now. Anyone knows something I would appreciate some help. Thanks

read the motherboard number off and try googling for wiring diagrams for that, laptop model isn't very helpful
