Troubleshooting: My computer won't turn on


After the obvious causes you are directed to perform anSMC reset. Read all the steps.

Resetting the SMC on Mac portables with a battery you can remove

  1. Shut down the computer.
  2. Disconnect the MagSafe power adapter from the computer, if it's connected.
  3. Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
  4. Press and hold the power button for 5 seconds.
  5. Release the power button.
  6. Reconnect the battery and MagSafe power adapter.
  7. Press the power button to turn on the computer.


Still having problems? Replace steps 6 and 7 with the following:

  1. Reconnect just the MagSafe power adapter.
  2. Press the power button to turn on the computer,
  3. Then reconnect the battery.


Resetting the SMC on portables with a battery you should not remove on your own


  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  4. Release all the keys and the power button at the same time.
  5. Press the power button to turn on the computer.

If you did everything in the troubleshooting article above, the last step is as follows:


If you tried all of the steps above and the computer still won't turn on, contact Apple technical support (1-800-APL-CARE in the U.S.) or take your computer to the nearest Apple Store or Apple Authorized Service Provider (AASP) for diagnosis. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).


Don't bother calling, since you already did everything they will tell you do to. Just schedule a Genuis Bar visit.


Since it is only a few months old Apple will fix it under warranty.

Hey John, Do you know what could be causing this PROBLEM? my macbookpro 15" 2008 Late was on and it the power cord came uplugged and I didn't notice it for a day or two and finally plugged it back up because the battery had went all the way down. But after a full charge it won't turn on. No noise but the Battery green lights are on says full charge on the little green dotted lights on the left side.

Funny how I decide to get a NEW MacBookPro 2013 Retina and a few days later now my MacBookPro goes out.

Hey myfz6, my late 2008 MacBook Pro unibody is doing the exact same thing after I didn't realize it was unplugged. Full power, full battery now but not a single sign of life. Did you need a new power supply? If so, could they replace it at the store the same day or did you need to send it in and wait several days? Please let us know, thanks.

Just troubleshooted an issue i was having with my (early 2014 retina) Mac Book Pro keyboard. All of a sudden, every time i started to type something (i.e. login account name and password) the mac suddenly powered off and tried restarting. This was occurring totally intermittently - no apparent cause. Of course had my tech support check it out and could not replicate, she brought my mac back to my office and as soon as i started typing, it died.


We found out it was pressure on the keyboard - I was typing the keys harder than everyone else.


Tech booted mac and applied pressure to the keyboard and it died, so it is off (thanks to apple care) to apple for a fix and i'm without my mac for a week! Hope this helps anybody out, because we couldn't figure that one out for a couple of days with unsuccessful system checks and virus scans.
