    I have an iBook G4 and I recently upgraded and replaced my hard drive because it stopped working. In the process, I pulled too hard on a connector in the upper left side of my computer (see picture at ifixit.com).

    The connector is now at a 45 degree angle, and while it is still attached, it is not functioning because the computer is not turning on. This makes since considering that the connector goes to the from the logic board to the button to turn on my computer...

    My questions are: Do you think there is a possibility this can be re-soldered on or do you think I need a whole new logic board and is there any way to start the computer without the physical button (i.e. a keystroke of some sort...)?

    Thank you so much!!!

    P.S. I know the logic and DC-in boards are working because my laptop battery charges...

    The connector is really too small for me to get a good look, but it appears like it might be a small molex connector. Which means that the wires are inserted into a small clip like holder that when pushed in, snap in place.

    If a wire is pulled loose (hard to see) you may be able to re-insert it with a needle like tool. There is also a possibility that the male side of the connector on the logic board itself might be at fault. In other words, one of the pins might be broken off or bent. Or, even worse, the bending (45 degree angle) has caused the circuit board to crack or break opening the circuit. You might be able to loosen the logic board enough to see if that's the case. If there is a crack or break, it is possible to repair the board if you have a low wattage soldering iron and a steady hand.

    Replacing an entire logic board can be expensive. :(

    You can give the resolder a try. I've been able to get it work, but you need to have a light touch. Only other way to boot it is to jumper the connectors with a screw driver (which means the case has to be open all the time).
