Remove one J1 philips screw.
Do not mix these screws up. If you put the longer screw where the shorter screw belongs, you will damage the shield around the keyboard.

Do not lift the battery out all the way, as it is still connected to the motherboard.
Do NOT puncture or deform the battery or it may catch fire or even explode.
