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.
