    Currently running a 2012 MBP and I have had a ton of issues, the one plaguing me now is that the computer will randomly shut off if not plugged in, and will randomly shut off during very intensive processes (Like HandBrake).

    First thing I thought, was battery but it looks normal:
    Charge Information:
    Charge Remaining (mAh): 6194
    Fully Charged: Yes
    Charging: No
    Full Charge Capacity (mAh): 6393
    Health Information:
    Cycle Count: 472
    Condition: Normal
    Battery Installed: Yes
    Amperage (mA): 0
    Voltage (mV): 12421

    Would really appreciate help with this, don't want to spend $110 on a battery that won't fix my problem.

    The computer has already murdered one SSD from it's random shut offs.

    The battery looks okay there. Try running the Apple Hardware Test to see what it turns up.

    Looks fine capacity wise. What's CPU usage like when it dies?

    When plugged in it's pegged at 100%, when not it's normal. (That's when they die)

    What process is using 100%? It shouldn't idle at 100% CPU use just because it's plugged in. This would suggest the overheating theory is correct.

    Handbrake, shrinking and converting video files. It doesn't get to Temps I haven't seen before. Fans spin up to 6200RPM at usual, at temps get to around 98* (I've had them get to 105* no problem). That still doesn't explain it shutting off at idle when unplugged.

    I ran the AHT, and it hangs at 21 seconds on the memory testing.

    Do you have some different RAM modules you can test with?

    I do, I am just running Memtest on the current set to see if that spits anything out, then I am going to swap them.

    Using the original RAM modules, it froze at 7 second.

    Dang. Looks like a more serious hardware issue I suppose. I think a visit to the Apple Store is in your future.

    Knowing my luck, it will be another shot Logic Board. Wish I had sprung for Apple Care when I had the chance. Prior to this, I've had the USB ports go dead, it was the Logic board failing. Hoping I don't have to pay $500 for a fix this time around.
