Hey, my MacBook Air 13” Mid 2013 was working fine up until this morning (never had anything spilled on it etc). I have been using it with an NVME SSD with an adapter for around a year without any issues. I replaced the original battery with an iFixit battery 2 days ago and everything was working fine, I had really good battery life again. I wanted to do the recommended calibration of the battery by fully charging it up until 100% and let the charger connected for at least 2 more hours, then discharge the battery completely to 0% and charge it up to 100"% again. So what I did was: I charged it up to 100% and let the charger plugged in for a few more hours yesterday evening. Then I used the Mac for a few hours and left it turned on (via the App Amphetamine to prevent it from sleeping) until it reached 0-3%. When it reaches 3% (I think) it automatically shuts down to prevent complete battery drainage, but I thought I had to completely drain the battery, so I left the device unplugged like that for 4-5h more. To make sure, it was completely out of charge, I connected my smartphone to charge it with the last mAh left in the battery. After that, I just plugged in the charger and let it charge until the charger showed the green light. And then I unplugged the charger this morning and turned the Mac on: No chime, no logo, no light, nothing. I tried various things that were recommended on the web, watched so many videos, nothing helps. -Resetting PRAM/NVRAM/SMC, didn’t help. -Unplugging the battery and connecting the charger -> fan starts to spin, charger LED is orange, system doesn’t boot (no screen, sound, keyboard backlight) when pressing the power button -Tried the same steps with the original battery and the original Apple SSD -> nothing changes When I plug the battery back in and connect the charger, it starts charging the battery (orange LED) and turns green when it finishes charging (I guess). So I assume everything is fine with the battery (iFixit and Apple one)? And when I disconnect the battery and connect the charger, the fan immediately starts spinning, so everything is fine with the power circuit I guess? And when I press the power button (battery plugged in, charger connecteed) the fan starts spinning, so that’s fine too. Where’s the problem then? I can’t believe this is happening. I have lots of important documents I need to access asap, my last time machine backup was a few weeks ago. I always kept my Mac clean, never damaged/dropped it, never spilled anything on it, why is this happening all of a sudden. Was it a mistake to fully discharge the battery? Ah and if there’s no solution to this, can somebody tell me, if I can access my data on my NVME SSD via an adapter on a Windows/Mac device, to at least gain access to my folders (SSD was not encrypted with FileVault, but I had a password set for my user account, if that’s important)? Thanks in advance for any advice!
Sadly you’re between a rock and a hard place ;-{ Using an M.2 SSD with an adapter in a Mac prevents you to use cases designed for Apple SSD’s like OWC Envoy Pro USB-A enclosure Here you’ll need one that can support the M.2 SSD like this one Envoy Pro EX USB-C (Thunderbolt 3 Compatible) External NVMe M.2 SSD enclosure So you’ll need a Mac with a USB-C port to read the drive. You can’t use a Windows or Linux system as Apples newer file system APFS is not supported in them. Even through you could get the add-on driver for Windows to read the older HFS+ based drives you are likely not going to be able to access the files unless you have a Windows based version of the application used to create it.
