    rMBP 13" Late 2012
    i5, 256 SSD

    Examples:

    1. When I go to bed and leave the macbook on (I don't put it to sleep or anything, just leave it there), when I wake up about 8 hours later, the macbook has shut off and to turn it back on I have to hold down Shift+Ctrl+Option+Power key simultaneously to turn it back on.

    2. When the macbook is not plugged in, it will shut itself off randomly as I am using it. Again, I have to Shift+Ctrl+Option+Power key simultaneously to turn it back on again.

    3. When the macbook is not plugged in, at times, it will just freeze as I am using it. Again, I have to Shift+Ctrl+Option+Power key simultaneously to turn it back on.

    I have noticed #2 and #3 happens a lot more frequently especially when I am connected to a Wifi away from home at a public space (school, Starbucks, Library, etc.).

    Solutions I have tried:

    1. Clean install of el Capitan
    2. Restored macbook
    3. Reset PRAM, SMC, etc.

    Does anyone know what my issue is or how to fix it? I cannot afford to buy a new macbook.

    Thanks and please help.

    Run AHT as suggested, or take it into Apple for diagnostics.
