Revive/update keeps data, restore wipes data. In case of corruption or damaged SSD, data could already be gone anyway.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

Re: MacBook Air 2018 A1932 820-01521 Not turning on.
What machine are you running the configurator software on? I had something similar with a 1932 that I restored.
I know that Apple's information gives a minumum version of software of like Catalina or something similar, and says you can use any machine to run configurator on, but I found I needed a machine that had only USB-C ports, and ran the latest patched version of MacOS available for the machine I was using.Comment

Re: MacBook Air 2018 A1932 820-01521 Not turning on.
What is the history of the unit?
Inspect the board to see if there is any liquid damage or damaged parts.
20v is good for the adapter voltage. Be sure the adapter is the suitable power rating for use on this unit.
Measure the voltage to ground of ppbus_g3h.Comment

Hi everyone!
I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.
I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM -
Hi,
I have a A1932 Macbook Air with Bootloop.
I already replaced the battery with a new one and reset NVRAM and SNC.
When I start the Macbook the Screen is coming on (no Logo) and switches of after a few seconds. If I start without the trackpad and keyboard it stays on longer.
If I use diagnostic (Option+D), recovery (Option+R) I always get the Apple logo and it go into online-Recovery. Even if I boot the installer from a USB-stick it ends up in online-recovery. Sometimes it crashed short after entering the wifi password, sometimes it loads the recovery... -

Hello,
With the power button connected it either boot loops with the apple logo or no display but the charging meter shows it looping on charging every few seconds.
No corrosion any where!
Tried a replacement power button off ebay and the same.
Very occasionally it will work with the power button connected!
Same results with or without the battery.
Can it be a fault with the Audio board or the mainboard?
The touch Id assembly connects through the Audio board first then to the Mainboard.

I have a 820-01521 that is stuck at 5V, and drawing just 230mA.
I did some troubleshooting, and managed to charge the battery up (was at 0%) using a different logic board.
Also I ran DFU and it did it successfully. Had to use a PMU_FORCE_DFU jumper to do it.
At this point the laptop started up and it successfully boots into the OS Install.
The charger is now at 20V, but drawing 0mA, so the laptop is essentially running off the battery. It doesn't detect the charger...
I think there could be a problem with one of the CD3215s, but all the LDOs are the...
