Hi !
You were right, again
Battery was the issue in the first place.
Being "Her Majesty Battery the IIIrd", so young in charge,
I was overthinking on a logic board problem.
Thanks for your precious help !

Re: Apple Magic Keyboard A1843 EMC 3138
Hi, new infos about the problem.
When the keys cable is detached, the Bluetooth comm is back, connected with the laptop.
Caps around the connector are at 3v without the cable and fall to 0 when re-attached.
I can see a small fold on the cable, surely a break inside the cable. It's obviously not replaceable so the next move will be scratching the cable coating, microscope and solder extra fine wires... And they are a lot !Leave a comment:

Re: 820-3437 battery not detected
You're definitly right, it was not a "genuine" one, clearly stated as Amazon after market.
Beside that why my 2005 iPod Classic 5th gen 60Go "video generation" is still working with good geniune battery ?! Alomst 20 years
Ok Amazon has accepted the exchange for my MBAir battery so we'll see how long the new one will last...Leave a comment:

820-3437 battery not detected
Hi,
My MacBook Air 2014 A1466 EMC 2632 doesn't detect the battery anymore.
The battery is new, almost... I changed it 3 months ago and it was working perfectly.
Now, there is no more battery icon. In the system list, it looks like there is no battery at all... I've tried resetting PRAM and SMC several times with no change.
With Magsafe2, the laptop is working, very slower than before.
When plugged, green light is on - fan spins - fan stops - orange light - fan spins - fan stops -
fan spins - start chimes.
I've checked Q7155 with and... -
