How to Reset MacBook Firmware

How to Replace a MacBook Battery (5 Steps)

Turn your MacBook upside down, with the Apple logo facing downward. Check the bottom panel for a removable battery. If the bottom panel is a solid block, you have a 'uni-body' MacBook, and the battery can only be replaced by an Apple authorized service technician.
Purchase a replacement battery from an Apple Store, an Apple authorized reseller or a third-party manufacturer. Be certain to purchase a battery specific to your MacBook model. Batteries made for other MacBooks may not fit in the case or may supply the wrong amount of power.
Use a coin to turn the circular lock slot of the battery clockwise 90 degrees, or one-quarter turn. The battery will pop out slightly, allowing you to lift it by its case out of the battery well.
Insert the new battery in the same orientation that the original battery was placed, lining up its connector with the power jack in the MacBook.
Press the battery gently and turn the lock slot counterclockwise to lock the battery in position.
