Introduzione

Sostituzione del case inferiore in alluminio nei MacBook Unibody.

  1. qPsGdXwUZZBT6RJa

    • Con il case chiuso, posizionare l'Unibody capovolto su una superficie piatta.

    • Premere il lato scanalato della chiusura di sgancio dello sportello di accesso, affinché sia possibile prendere l'estremità libera con le mani. Sollevare la chiusura di sgancio finché non è in posizione verticale.

    This is not a a1278 unibody MacBook Pro. A1278 MacBooks backs are one solid metal piece not two separate pieces. This guide is for a different MacBook Pro.

    This guide isn’t for a pro; it’s a MacBook unibody.

    So, it turns out that Apple used the model code A1278 for quite a few different Mac models, including both Pro and non-Pro versions! This guide is for the non-Pro Macbooks. There’s also one for the Pro models with the same A1278 identifier.

    • Adesso, lo sportello di accesso dovrebbe essere abbastanza rialzato per sollevarlo e rimuoverlo dall'Unibody.

    • Verificare che la chiusura di sgancio dello sportello di accesso sia in posizione verticale prima di procedere.

    • Prendere la linguetta di plastica bianca ed estrarre la batteria, rimuovendola dall'Unibody.

    Great tutorial ! great step !

    Even though it’s specifically stated, you have to make sure the access door latch is vertical or the battery won’t be removable.

    • Rimuovere le otto viti seguenti, che fissano il case inferiore al case:

    • Una vite con testa a croce da 3 mm.

    • Tre viti con testa a croce da 13,5 mm.

    • Quattro viti con testa a croce da 3,5 mm.

    On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

    Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...

    Be very carefull with your screws! Especially those on the inside.

    You can get away with a Phillips #00 for many of the screws involved but the 4 at the bottom case split are likely to strip if you don’t use a JIS #00 or, in a pinch, a Phillips #000.

    I used the Phillips #00 tip from my Pro Tech Toolkit, and it worked well enough. But yes, maybe #000 might have been better on the lower row of screws. Note to myself: Always read the comments first.

    When replacing these screws, the order to replace them in is as follows:

    1, Top left

    2. Top right

    3. Top center-left

    4. Top center-right

    5. Bottom center-right

    6. Bottom center-left

    7. Bottom right

    8. Bottom left

    I hope this information is helpful.

    I followed my usual process of putting in all the screws loosely, then tightening them gradually in distributed pattern, to help ensure that the panel settles in place evenly. But maybe some orders are better.

    • Con entrambe le mani, sollevare il case inferiore da quello superiore.

    Thanks for the guide!

    It's implicit in the two photos, but worth mentioning because it blocked my progress in this step for a bit: You have to put the release latch back into its horizontal, closed position before you can lift off the lower-case panel.

Conclusione

Per riassemblare il dispositivo, seguire queste istruzioni in ordine inverso.

Is there a way to get replacements for the rubber feet without replacing the entire lower case and access panel?
