    • Simultaneously slide the battery latches (outlined by the red box) to the dock connector in the middle.

    • This will release the battery. Just slide the battery away from the computer.

    • Open up the computer and press and hold the power button for 5 seconds. This drains any power left inside the computer.

    • This is important, as if electricity remains in the notebook, it can shock you and damage the logic board.

    • Loosen the center screw with a philips screw driver. This is the only screw that needs to be loosened.

    • It can't be removed as it is captive the the bottom plate.

    • Now slide the plate away from the dock connector.

    • Use a plastic opening tool or a spudger to remove the antennas.

    • I use my fingers, but the picture shows and iPod opening tool because most adults have bigger fingers.

    • I'm 14, so my fingers are small enough.

    • Some E6400 models have a card with three connections-a gray wire in the middle-marked appropriately.

    • The card should instantly pop to an angle less than 45 degrees once the screw is removed.

    • Now simply pull the card strait away from the slot.

    • Install a new card by sliding it in the direction of the arrow and pressing firmly down until it clicks.

    • Slide the bottom plate on.

    • Slide it to the rear of the notebook. (battery compartment)

    • Tighten the screw.

    • Do not over-tighten. Doing so will strip the screw.

Why is your soundcloud linked as the wifi card site. It is really not appropriate considering how great of a job you did with the instructions for this repair.
