How to Clean the Screen on a MacBook (5 Steps)

Turn off the computer, unplug the power cord and remove the battery. Whenever using liquid of any kind around a MacBook, or any computer, it is important to have all power to the unit turned off and removed to protect you from shock.
Dampen a soft, lint-free cloth with water. Don't use anything other than water unless it is purchased from an authorized Apple Dealer. It is important that liquid is not sprayed directly onto the screen.
Gently wipe the screen with the dampened cloth. Even using just a cloth and water it is easy to clean off most smudges and fingerprints from the screen.
Wipe the screen down with a soft dry cloth after it has been cleaned to dry any liquid still on the screen and prevent streaking.
Replace the battery, plug the power adapter back in and power up the MacBook. The screen will be crisp and clear. It is a good idea to clean the screen every month to prevent the build up of grime.

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.
