No boot on battery power - 820-3435-B
Hi guys,
So I picked up a cheap MacBook Air 2014 (820-3435-B) which had a puff of smoke out of the back when being used.
Apple store said to the guy it was “a blown transistor”.
I opened it up and could see one of the capacitors was damaged (C7140) and crumbling. I replaced it which was a feat for me! Plugged in and it turned on, there isn’t an SSD so I got a flashing folder which I was really happy with!
However, I’ve now realised it doesn’t boot on battery power. Where do I go from here? I checked R7006 which was fine from what I could tell.
I am installing Catalina tomorrow so I will be able to tell if the battery is recognised and if charge is shown.
Feeling deflated after what I thought was a great success!
EDIT
Entered the following in Terminal “pmset -g batt”
Now drawing from ‘AC Power’
-InternalBattery-0 (id=11337827) 0%; AC attached; not charging (Poor/Good)
failure: “Permanent Battery Failure”
Detailed failures: “Externally Indicated Failure” present: true
EDIT 2 - Ran CoconutBattery
EDIT 3
It was indeed the battery, bought a used one on eBay and it works perfectly
Esta é uma boa pergunta?
After you get the OS installed download this app CoconutBattery lets see what it tells us. Post a snapshot of the main window here for us to see Adicionar imagens a uma pergunta já existente

@danj Hi Dan, so I can't install an OS at the moment as the SSD adapter I ordered was wrong! :(
But I am booting from USB and I have updated my post with the error I get in terminal!

Can you install CoconutBattery onto your booting drive. I find that offers more useful information combined. You don't need the full version.

@danj It is a macOS install drive, how can I install it on there? Sorry I am not the most fluent mac user!

Well you can't do it to the bootable OS installer drive, but creating a bootable drive (using the installer to create it) you can then just install it double clicking on the installer file.
