When taking out the battery, please include: on the battery connector, slide the metal clip UP and then remove the battery connector.

I nearly cracked my motherboard because you did not mention that the battery connector was held in place by the metal clip which slides upwards.

Please add this or you have your viewers bricking their brand new laptop like I nearly did.
