Introduction

Prerequisite-only guide to disconnect the battery in a 2019 MacBook Air.

Tools

Step 1

Peel back the tape covering the battery connector enough to reveal the connector underneath.

Step 2

Use a spudger to slide the battery connector parallel to the logic board and out of its socket on the logic board.

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.

This seems like an important step?

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

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

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.

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).
