    • Turn off the laptop and remove the battery.

    • Remove two screws securing the Keyboard.

    • The Keyboard is held by two locking clips, under the battery. Use the sharp tip of a plastic tool to release the keyboard.

    • Remove 4x phillips screws and disconnect:

    • Power On button flex cable

    • Touch pad flex cable

    • Remove 18x Phillips screws from the bottom cover.

    • Remove any memory SD Card from the Card reader.

    • Start opening with a plastic opening tool.

    After removing the 18x Phillips screws, the laptop is VERY fragile in the hinge area. The bottom cover will easily crack or break in the hinge area when opening the laptop with no screws, particularly the left side near the power button. Possibly this step should be revised to recommend opening the laptop 90 degrees before removing the 18x screws. Or, advise extreme caution when opening the laptop with no screws.

    Hi, do you know where buy screws that you mention in step 4? “Remove 18x Phillips screws from the bottom cover.”

    I am italian. Thank you anyway.

    The laptop I have included 6x screws from inside and 16x screws from the bottom. This seems to be a minor variation from model to model.

    • Carefully separate the upper cover and remove it.

    In my unit, there was also a screw holding the DVD drive in place, just toward the center from the drive itself. This screw also had to be removed to be able to remove the upper cover

Perfect! Thank you for the instructions. Thought I'd bricked my laptop, but I followed your instructions and left the battery out for 5 mins. Re-assembled and it's as good as new.
