Usa questa guida per sostituire la barra dell'antenna di un MacBook Air 2019.

    • Prima di iniziare questa procedura dovresti disabilitare la funzionalità Auto Boot del tuo Mac. Auto Boot accende il tuo Mac quando apri il coperchio con lo schermo può attivarsi accidentalmente in fase di smontaggio. Usa questa guida oppure segui le istruzioni abbreviate qui sotto per disabilitare Auto Boot.

    • Se il tuo MacBook funziona con Big Sur v11.1 o successive, disattivare l'Auto Boot potrebbe non funzionare. Puoi procedere normalmente, ma assicurati di scollegare la batteria appena sei dentro.

    • Prima di iniziare, spegni completamente e stacca dall'alimentazione il tuo MacBook Pro. Richiudi il display e ribalta il laptop mettendolo a faccia in giù.

    • Usa un cacciavite pentalobe P5 per rimuovere le viti seguenti:

    • Due viti da 7,9 mm

    • Due viti da 7,1 mm

    • Sei viti da 2,6 mm

    If the first thing you do is disconnect the battery, is it really an issue if you don’t (or can’t) disable auto-boot?

    I agree, why disable Auto-Boot when the lid is closed and the battery is disconnected immediately? – I've never had an issue since 2016 when the feature was introduced.

    On my machine, the longest two screws were in the corners, while the other two long screws were in the middle. Perhaps previous service in the past had them replaced into the wrong place? In any case, the longest screws do seem to fit in either place. I guess 0.8mm is not very much of a difference. Seems like poor design if they could have used one size of screw.

    johann beda -

    Just did one, and it also had longest screws in the corners.

    maccentric -

    Just did another, and the long ones were in the middle. Definitely poor design and quality control.

    • Infila le dita tra lo schermo e il case inferiore per sollevare dall'Air la cover stessa.

    • Rimuovi il case inferiore.

    • Dopo il rimontaggio, il tuo MacBook potrebbe non accendersi finché non è collegato a una fonte di alimentazione (un caricabatterie per smartphone a bassa potenza potrebbe funzionare). Per testare la tua riparazione, collega il caricatore, attendi due minuti affinché il tuo MacBook si accenda e verifica che tutto funzioni come previsto.

    Das geht etwas schwer, da das Unterteil mittig noch von 2 Druckverschlüssen gehalten wird.

    translated and true:
    This is a bit difficult because the lower part is still held in the middle by 2 pressure fasteners.

    Tom -

    Are there any suggestions to removing the pressure fasteners more easily?

    • Stacca il nastro adesivo che copre il connettore della batteria quanto basta per scoprire lo stesso connettore.

    • Usa uno spudger per far scorrere il connettore della batteria parallelamente alla scheda logica, tirandolo fuori dal suo zoccolo sulla scheda.

    Before the battery can be fully disconnected, the battery disconnect button needs to be held down. There is a gold button just above the battery socket, along with a small LED much like the 12” machines. Once this has been held down and the LED has switched off it is safe to remove the battery.

    Aaron Dalziel -

    This seems like an important step?

    maccentric -

    Also, seems like this should be done after the battery is disconnected, not before? Otherwise, wouldn’t the battery re-charge it?

    maccentric -

    What if the white LED dosent light up after pressing the yellow button again?

    Iron05 -

    I just performed this repair on my late 2018 mac air. I did click the gold button but saw no LED illuminated or otherwise. Question- after reassembly does the button get pressed again to connect the battery? Please clarify if this button is to be pressed and if it needs pressing again after the repair.

    All said - I pressed again after the battery connector clicked, assembled the back and all worked perfectly. The original issue was one dead port (no charge, no communication). The battery charge lightening bold icon was acting funny too. Genuis bar guy in Naperville said it was likely a logic board too. But it was not. The port was apparently confusing the logic board with regards to the charge function. Thanks Adam for saving me $440 and sending my computer back to Apple. I am 71 yrs young - who says an old dog can’t learn new tricks with good training!!

    I didn't see Aaron's comment before completing the battery replacement. Afterwards, the computer would not turn on despite multiple SMC reset procedures. Upon double-checking the comments I see the importance of pressing the gold button. I pressed the gold button before disconnecting the new battery, then pressed it again after reconnecting for good measure. Computer booted!

    It would be good of iFixit to add this important step as most people probably don't open up every single comment on (seemingly) simple steps.

    Corey Matsumoto -

    Seconding Corey's comment. If paid more attention to the comment section, I would have avoided 15-30 minutes of panic. (BTW I did not notice any LED, but the golden button was easy to find).

    Lorenzo Sorbo -

    Where is the gold button? I replaced my battery and my laptop will not start

    • Usa un cacciavite Torx T3 per rimuovere le due viti da 1,4 mm che fissano la staffa del cavo dell'antenna.

    • Rimuovi la staffa del cavo dell'antenna.

    It is a T4 not a T3

    • Inserisci l'estremità punta di uno spudger sotto uno dei cavi di antenna, vicino al connettore.

    • Fai leva verso l'altro per scollegare il cavo.

    • Ripeti l'operazione per l'altro cavo di antenna.

    As you are putting everything back together, it is a bit wonky trying to reconnect these antenna. Patience is necessary and it helps if you reshape the cables so that the cables are like the picture.

    • Usa un cacciavite Torx T5 per rimuovere le viti seguenti:

    • Quattro viti da 7,4 mm

    • Due viti da 4,5 mm

    The tool list does not list a T5.

    • Solleva nella barra dell'antenna verso l'alto ed estraila dal case. Fai attenzione che non si impigli in cavi e connettori presenti sul case.

    • Potresti incontrare un po' di resistenza da parte delle clip nella parte centrale della barra che la ancorano al case. Tieni conto che, se tiri direttamente verso l'alto perpendicolarmente al case, puoi tirare con una certa forza senza danneggiare nulla.

    • Rimuovi la barra dell'antenna.

    Tip: keep the six big lid anchor screws in place until after you remove the antenna bar. You may have to use your plastics spudger to wedge underneath the vents and get leverage off the underside of the lid along the hinge area. I also had to remove the Logicboard so I could get the plastic spudger underneath the antenna bar and lift it up. It felt like it was going to break. Did not want to have to remove the logic board, but seemed that was the only way I could get underneath and pry the antenna out.

    Chris Leeds -

    Felt like I was going to break it! It will come out but it requires patience and light touch

    Lamar's suggestion to view the video is excellent. Though I saw it only in arrears, it was quite valuable. I found a spudge, used to GENTLY pry both side first, then begin lifting on your right side (with back of laptop facing you) while gently twisting slightly inward to do the trick.

    Probably the worst moment in this repair.
