2 MBPro13" shuts down during boot, recovery boot and internet recovery
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 :)

What is your SSD drive? Make & Model

I've a standard Apple HDD from Seagate, no SSD.

I'm thinking you have a bad SATA cable here, which can explain the OS's inability to load properly. Most of the time I see this when people have upgraded to newer SATA III (6.0 Gb/s) drives and mostly SSD's Vs HDD's.
The fact diagnostics runs without failure also points to this as well.
FYI: SMC wouldn't be the issue as that only controls the thermals and a charging. If you has a 15" model then I would have suspected the dedicated GPU as messing up. The 13" model doesn't have a dedicated GPU it uses the graphics engine within the CPU.

Can I try booting my HDD from an external USB drive? I'll remove my HDD from the internal bay. Have I to disconnect the sata cable too?

If your internal drive has a bad OS, moving it to an external case won't be as useful that having a known good drive you setup from another Mac.
The internal SATA cable can be left in place (just disconnecting the drive)
