    My 1.2 GHz 512GB MacBook will not power up, I have just got home and it did seem a bit cold. Not cold enough for any damage but cold. It would not power up so I plugged it in and it made the charging sound. So It seems to still be working, tried a power cycle and no joy. Any ideas? Need it running for A-Levels tomorrow... thanks

    Try holding down the "Power" key for a good 30+ seconds, next up would be try an SMC Reset. Once the SMC resets you should see the charging image on the display. Notebook will then boot normally, after this it gets trickier; is it charged, is the charger and to cable good, now we are down to hardware.

    The SMC reset on the rMB seems a little more difficult to achieve, like it`s more sensitive to the timing, have seen some post reflecting the same. I tried resetting my rMB out of curiosity and it took a couple of goes to get it right.

    Anybody else have another rMB to try the power pack and cable? Number "1" question right now is are you backed up?, the computer you can live with going down, the data not so.

    I remember reading you had a previous issue with your MacBook. I would take it in to the Apple store and get it looked at, as you need it up and running for exams etc.

    Yes, that was me! I have been talking with a chat rep and it seems to be fine now... last time that just turned out to be the three pins on the charger wall plug which I got replaced for free

    As your average insanely paranoid student I have it all backed up, iCloud Drive, USB Stick, time capsule, downloaded and stored locally on my MacBook Pro when I get home... I just have to be sure of these things!

    But all seems okay now, diagnostics found nothing. But I will keep an eye on it, the machine is the best I have ever had when it works. and taking into account my exams, I have not seen anyone on the forum seem so genuinely concerned before!

    Thank you, all sorted now (admins can close this thread if they like)

    Obvious question that may help others in the same situation, what worked, how did you restart the Notebook.

    Honestly, after trying to start it with a long press (30 seconds) followed by hitting the power button and (COMMAND+OPTION/ALT/P+R) we had nothing. then after trying to hold the power button for about twenty seconds it just started as normal. Weird but glad it works!
