If there is a tab connected to the battery connector, use it to pull it out of the socket. If there is no tab connected, you can use a spudger or cocktail pick to push the connector out.
The screws will remain attached to the bracket that is holding the drive in place.
If there is no tab affixed you can use your fingers to gently lift the drive out.
Pull the hard drive completely out of the MacBook so that you can access the screws on the sides of the drive.
You can also peel the pull tab off of the old drive and set it aside to stick to the new one.
An SSD will provide significantly quicker loading times, but are typically much more expensive than traditional hard drives.
You can re-affix the pull tab too if you’d like. Stick it to the underside of the drive (making sure not to contact any circuitry) so that the tap sticks up when the drive is inserted.
