    • Seven 3 mm Phillips screws.

    • Three 13.5 mm Phillips screws.

  3. MacBook Pro 15" Unibody 2.53 GHz Mid 2009 Microphone Replacement, Battery: étape 3, image 1 de 1
    Outil utilisé dans cette étape :
    P6 Pentalobe Screwdriver 2009 15" MacBook Pro Battery
    $5.49

    • Three Pentalobe screws secure the battery to the upper case. They can be removed with this special driver.

    • If you don't have a Pentalobe driver, a 1.5 mm flathead screwdriver can be used in a pinch. Be sure the head of your flathead screwdriver fits snugly across two of the five "points" of the screw head before trying to break the screw free, as a loose fit will easily strip the screw head.

    • If the head of your screwdriver fits too loosely, find a bigger bit and file it down until it fits snugly before proceeding.

    • You do not necessarily have to follow steps 3-7 to remove the battery in order to replace the hard drive. However, it is recommended to remove all power sources from electronics before working on them.

    Modifier

    • Remove the two exposed five-point Pentalobe screws along the top edge of the battery.
