Macbook does NOT power on / boot up anymore!

    Today I carefully took apart the top case of my macbook to replace the inverter cable.

    After I replaced the inverter cable, and before I re-assembled the parts back, I checked to make sure that everything worked fine. It powered on and the LCD worked again. Yay... So I went ahead and carefully re-assembled all the parts and screws back.

    I pressed the power button, but surprisingly the macbook no longer power on or boot up! I get absolutely no noise, no reaction, no response whatsoever.

    My battery is full, and the power cable has the green light when plugged into the macbook. Also, I am sure the metallic strip from the bottom of the topcase is connected to the logic board.

    Could someone please provide any insight/advise? Could the logic board be broken? My warranty ran out a few months ago :(

    Check if the keyboard/power ribbon stays connected to the motherboard *after* you assemble. This happened to me when I replaced the hard drive - machine would power on prior to assembly but fail to respond in any way shape or form after assembly - turned out I had to be extra careful so the ribbon does not disconnect while pressing/moving the top cover.

    Thanks for your quick response. Yes the power ribbon is still connected to the logic board, but still no power.
