MacBook Air SMC problem

Hi all,

I have a problem with my macbook air 6,2.

The first issue was the computer did't turned on.

The SMC reset and regular things did't helped.

I took down the bottom case, and plugged out the battery cable. After this when I plugged in the charger, the computer is turned on immediately.

I took back the case, and restarted the computer, the computer was dead as before.

I ran a hardware diagnostic test and got the PPT001 (battery), PFM001 (SMC) and NDC001 (webcam - this one is weird because I can use the camera).

So right now I can turn on the computer without the bottom case, but the fans are running high etc.

The power adapter led is not lighting, and when I push the shift + ctrl + alt the computer is turned off immediately.

Anyone have an idea what can I do with this SMC issue?

Hi,

I have exactly same issue with my Macbook Air 13" 2014.

How do you repair it?

by

First issue was fixed without any intervention. I just waited few days..

The secound issue was the SSD, so I just replaced it. Maybe the first issue was an SSD issue as well.

Yeah it was my first idea. Few days later the computer turned on and worked fine.

But another few days later started to do a weird things, for example restart without any reason. After one of the restart the OS never started again. I checked the SSD with the install system, and haven't seen it, so I ordered a new SSD, and now everything is fine.

Maybe the first issue reason also was the SSD.

Hi,

unfortunately your SMC (System Management Controller) might be broken.
