  1. Nice guide, but doesn’t show how to remove the part above the keyboard. My power button is pressed in, wasn’t forced in, just pressed it one day and it just ‘went’ down, and stayed down. Not sure how to open it to fix just that problem.

    1. hey have the same problem with the Latitude E6540 Power button been press down and stayed down, just wondering if you ever found a fix for it i would really appreciated.

        1. i discovered that it is connected to the motherboard, so the solution is to get another motherboard and replace. a very great disadvantage

        2. I am looking for a solution to this exact problem as well.

          Did anyone ever figure out how to take apart the area where the power button is?

  2. You forgot to include the screen disassembly. There are no external screws on the display bezel of this model so removing the screen can be a bit tricky.

  3. And must you remove the DVD drive first? (IT installed the screw in the DVD drive’s eject button – thus not allowing the entire drive to be removed.)
