This morning I was using it, and it was working fine. I came home this evening, plugged my MacBook into the MagSafe power adapter and went to power it on - and nothing happened. It is responding to the power adapter (ie lights up green initially and the orange) but I cannot get it to respond. At one stage I did hear a brief chime as if it was rebooting, but it cut off again.


I have tried everything I can find online - holding down the power button, holding down power, option and command, etc but nothing is working. I have only owned this laptop for a couple of months and I cannot think of anything that would have damaged it. As I say, it as working this morning.


I am desperate for help as I am currently abroad and not near an Apple Store and my laptop is essential for the work I am doing so any help would be greatly appreciated.

    Reset SMC.

    The good news is that is still under the one year limited warranty.


    Startup your Mac in Safe Mode


    A Safe Mode boot takes a longer than a normal boot so be patient.


    Once you are in Safe Mode, click Restart from the Apple () menu.


    If that doesn't help, see if you can access OS X Recovery.


    Turn the Mac off, wait about ten seconds then startup while holding down the Command + R keys. Let go of the keys when you see the spinning progress indicator.


    From there you should be able to access the utilities in recovery mode to verify and repair the disk if necesssary, or reinstal OS X.


    Read before proceeding >  OS X: About OS X Recovery


    If you can't boot into recovery mode, contact Apple for instructions for sending in your Mac for service > Contact Us - Apple Store

    I have tried to reset SMC and still no signs of life!


    I am also unable to start my Mac using safe mode, as nothing happens no matter how long I hold down the power key! I really am stumped - what could have killed my laptop in the space of a few hours? I have never dropped or otherwise damaged it.

  • Carolyn Samit Level 10 (103,365 points)

    Did you try OS X Recovery as I suggested previously ?????


    If you heard a chime, then the Mac is powered up, it's just not passing it's startup diagnostics test.

    Hi, yes, I have tried but despite hearing a chime I simply cannot get it to 'wake up' - no matter what keys I hold down, the screen is black, I see no apple logo.

    It is unfortunate that there is no Apple store nearby.


    Try resetting SMC one more time.


    Make sure that another outlet is used, left side keyboard keys are pressed and keys are pressed down


    for about 20 seconds.


    All 4 keys are released at the same time.


    Then press the key for power.

    Still nothing!


    I have left it on charge and the light has gone from orange to green, indicating it is fully charged. Is there absolutely nothing else I can try?

  • dominic23 Level 8 (37,807 points)

    Disconnect the computer from the power and try to turn it on.


    If this does not help, you may have to wait until you are back home to get it fixed.


    Wish I could be more helpful.

    Okay interesting development - after carefully inspecting it for a while (turning it in my hand) the fans have powered on - very loudly. Still nothing else but what could this mean?!

  • dominic23 Level 8 (37,807 points)

    Thermal sensors  not working properly, probably.


    Only Apple store can diagnose it correctly.


    Here is an article from Apple about this issue.

    So today I took it out of the case just to try again, and bam! It turned on. Just like that. Very, very strange but I'm not complaining! Thank you for all of your help.

  • dominic23 Level 8 (37,807 points)

    Great. Glad it is working .

    Did your MBA continue to work after it came back on? Mine did the same about two weeks ago (I've not had it longer than a month), and I was thrilled after a few days it magically powered up after nearly a week of nothing. But a few days ago it died and won't power up again. Light has changed from orange to green, tried every reboot I can find, called Apple, etc. I'm taking it in tomorrow, so I guess I'm just curious about what to expect. This seems to be a frequent occurrence among Air owners, from what I've read online...

    Mine is doing. I had a MBA from 2010 that died this year. But it never had this problem. If it's happening to everyone that mean the product is defective . Apple needs to recall and extent people warranty on it. I don't think it's right for us to be stuck with brand new computer that just turns on and off whenever it pleased. This seems to be a known issue for this model and apple needs to fix it!
