Complaint follows. The client restarted their computer and the problem resolved. Any one else experience this problem? Know what causes it?


Hi - Since I opened my laptop this morning every minute or so my monitor screen will just shut off (go dark) even while I am using it and typing. If I click a key or move my mouse it comes back on but goes dark again a minute later. I have no changed any settings and even checked my screen saver and energy settings but none of them have changed. The screen shut off 4 times while writing this email.

From what I have read on Apple forum sites many are having big troubles after upgrading to Maverick 10.9.4. What the fix is if any I have no idea but hopefully one of the Apple experts here will point in the right direction.

It's likely a 10.9.4 issue but they can try resetting the SMC (power controller) per Apple's instructions here. Two methods depending on if it has a removeable battery or not.





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

Note: Learn about removing the battery on MacBook and MacBook Pro.

  1. Shut down the computer.
  2. Disconnect the MagSafe power adapter from the computer, if it's connected.
  3. Remove the battery.
  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.
Resetting the SMC on portables with a battery you should not remove on your own

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its 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.
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
