Mac book air won't turn on after shutting down unexpectedly

I was surfing the internet, when it all of a sudden went black and shut off. No warnings or anything.
The light on the charger no longer lights up. I have tried all the tips on apple website and nothing works.
Any suggestions?

Try resetting your SMC.
Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
Note: This will not delete any data.
The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
I hope I helped.

  • MBP won't turn off after shut down

    My MacBook Pro with upgrade to Leopard is staying hot after shut down. I am having to remove the battery to make sure, otherwise I have one red hot laptop when I open up my backpack. Is this another Leopard issue?

    Good morning,
    No, this isn't an issue I experience with Leopard...
    I'd try [Resetting your MacBook Pro System Management Controller (SMC)|http://docs.info.apple.com/article.html?artnum=303319] and see if that solves your issue.
    Hope this helps! 

  • Mac book pro won't turn on after after accidentally shutting it down during updating

    Please help, I was updating my Mac book pro and accidentally shut it off.  Now it wont turn on, it shows the apple logo and the continuous cycle circle. 

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 8
    This step applies only to a pre-2013 Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • Unibody 15" Mac Book Pro won't turn on after Left Fan replacement

    Hi Guys,
    Over the last few days the crackling noises from my fan had gotten worse, so I decided to take some action and I replaced fan myself.
    Now I've fitted the new fan but when I try to turn the computer on, nothing happens, nothing at all.
    The power button seems unresponsive. I've tried starting the computer both with a fully charged battery and on only power but this still doesn't seem to work.
    Could someone please advise!
    Thanks!

    You have a machine that's still under the manufacturer warranty, and you decided to DIY (do-it-yourself) and you DIW (did-it-wrong). Not sure why you wouldn't just have taken it in for service...
    Take it to Apple. You'll have to pay for them to fix it now, in all likelihood, since you caused a bigger problem by attempting to fix the original problem yourself.

  • Hello, my mac book air won't update. Every time i try it goes onto the purple starry screen and stays that way for hours, so i just have to shut it down. I have deleted a lot on my laptop so there is enough space, please help?

    I believe that system has a hall sensor on it to detect when the lid is closed so it can put the system to sleep and/or disable the monitor so it can be used with an external monitor only. If the sensor is marginal or has a bad cable, it may intermittently cut the monitor on and off, and may likewise put the system to sleep. One way to check would be to plug in an external monitor and if the laptop's screen cuts off or doesn't show up, start using the trackpad and press on a non-typing key like the shift key. If the external display suddenly pops and becomes active while the laptop display remains black, it's probably a problem with the sensor or the cable/connection. You might be able to fool the sensor into kicking on and off by moving a magnet over it. It's located on the left had side of the base with the unit opened up, and right over the audio output plug.
    I know of some people that put a small magnet right over the hall sensor's location so the laptop display turns off and they use the system with an external monitor, keyboard, and mouse. If fooling with magnets, make sure they're small and don't get them close to the hard drive because a strong magnet can wipe them out.
    I don't know if this will help you much, but it might.

    My Mac book pro won't turn on at all and when i put it to charge the light blinks, what should I do?

    Yes if your model MBP has a removable battery.  If it does not: 
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • Fan doesn't turn off after shut down on 15" MBP C2D

    The fan on my 2-day old MBP C2D stays on even after shut down. The speed of the fan even changes. 3 hours after I shut down the fan was still spinning. I pulled the battery and pressed the power button to reset the SMC. As soon as I put the battery back in the fan immediately started spinning again. I didn't even power it on. When I do power it on the fan stops.
    My Macbook Pro is actually noisier when it's off than when it's powered on. Has anyone else encountered this. Hopefully there's an easy fix, I don't want to have to leave it with the Apple Store.
