Unwrap the new battery. Place the new battery in at an angle, sliding it below the brackets. Press the battery down to secure it.

How to Upgrade the Memory in a MacBook Pro

Use your MacBook Pro User Guide to determine the type of memory module you need and the amount of memory your system can handle. If you don't have a hard copy of your User Guide, you can download one from the Apple website (the link is available in the resources section).
Power down the MacBook Pro to a point where the computer is completely off.
Turn the computer over so that the bottom is facing upward.
Touch a non-painted metal object to remove the static off your body. Working on a computer's internal components with static on your body could damage the hardware. Also, refrain from walking around until you have finished upgrading the memory because moving around can generate more static.
Remove the battery from the MacBook Pro.
Use the Phillips-head screwdriver to remove the three screws from the memory module cover. Put the screws in a place where they won't be lost.
Slide off the memory module cover and put it where you put the screws. Now you should be able to see the memory module(s).
Push out the tabs on the empty memory module port to prepare for inserting the new memory module.
Hold the memory module by the edge of the part (so you don't damage the module) and insert the memory module into the empty port. Fold the part down into the memory module compartment.
Replace the memory module cover and the battery and start up your MacBook Pro. The memory will automatically be discovered by the system once you've started up your system.
