This is the battery. For guides that are for other parts, the battery is removed for the reason of it being a pain to connect or disconnect while screwed in.

Be careful not to short anything on the motherboard, as the battery cannot be disconnected before removal.

Remove four J1 Philips screws.

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.

Lift the battery slightly using your plastic opening tool.

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.
