2015 MBA Power Issue
I'm having some issues with a macbook air that I'm currently trying to diagnose, I've done all kinds of research with no luck.
The model is A1466, and it's an Early 2015. The EMC is 2925
When this computer is on, it seems to run totally fine. But as soon as you shut it off, it will not turn back on at all. The only way that I've found to get it to turn back on is open it up, unplug the battery, plug it back in, and then plug in the charger. From there it will turn on and work fine. The keyboard works totally fine when it's on, so I know it's not a keyboard issue. I tried using the jump pads to boot it in case it was an issue with the power button, and I ran into the same issue.
When I was originally diagnosing this device, the only diagnostic error that I got was the battery needing to be serviced. I ordered a replacement battery, and I also reinstalled the operating system on the machine (El Capitan).
Neither of these fixed the issue, and now it's giving me 2 different errors:
- PFM006 - Issue with the SMC
- PPN001 - Issue with the power management system
As I said, I've checked everywhere and I can't seem to find much info on getting these fixed. I would like to repair it in house if possible, as opposed to just sending the unit to Apple.
I can do some soldering work if needed, I just need info on what to replace or check for. I have pulled the board from the machine, and I'm not seeing anything that is burnt or looks damaged. This computer has no signs of water damage at all.
Any help is appreciated, if I'm able to find any more info I'll update this thread for others to see!
