Hi all, first question here :)
I’m facing very odd behaviors on my mbpro, can you help me fixing it?
Laptop: MacBook Pro 8,1 (Late 2011)
List of related (I think) issues:
* shuts down during boot: Apple Logo, progress bar ~10%
* shuts down during recovery boot (Cmd + R): Apple Logo, progress bar ~10%
* shuts down after internet recovery (Cmd + Option + R): sometimes I can see the GUI sometimes not
* charger light behaves oddly: sometimes doesn't turn on and sometimes is working well (can't get the logic)
* after a random shutdown I can restart the Mac only resetting SMC, if I don't reset the SMC the power button is dead
What I did so far:
* changed battery with a new one (side leds are Ok)
* run without battery, same issues
* run without HDD, internet recovery issue
* SMC + PRAM reset
* removed HDD and used a new one with internet recovery, same issues
* run Apple Hardware Test (D) both short and extended mode, no errors in both cases
* changed thermal paste
Booting with Cmd + V:

Question: What I can do right now?
My two cents: dying SMC controller?
Thank you all for your time :)
