MacBook Pro's screen randomly goes blank (white sometimes dark), wont be able to do anything no matter what key i press unless i turn it off and on via the power button. When i do that I normally have just a few minutes before it happens again. Bought this back in december just started happening a few days ago. Only thing out of the ordinary I've done is install that microsoft silverlight or whatever it is netflix asked me to install to watch the videos but I uninstalled that quickly hoping it would fix my problem but it hasn't so please help me out if you know what to do
Try a SMC reset:

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it. I've tried different power plugs. Going direct into the wall, through a power strip. By iteslf, with other devices plugged in. I removed hard drives, and some RAM, and nothing. Sometimes it would not turn on, and then some minutes later it works. So its was sparatic, but now its been the same situation for three days where it wont turn on.
I'm guessing power supply, but I wanted to see if anyone had a similar expereince and what the solution was, before I drag this beast to my local Apple store and have them look at it. Its a real pain to get it there and back and I want to be armed with some info for them. I already dragged this to them when it first started to do this, and of course it started up just fine for them. And you know if it works for the Genius then theres nothing wrong with. No matter what you explain to them.
I figure if anyone had a the same problem and was able to resolve it, I can relate that experience to the Genius even if it start up for them.
ThanksTry a SMC Reset using the extended method:
Remove the AC power cord.
Press the power-on button. [This drains the stored charge from the power supply]
wait a quarter minute.
Restore the power cord, being certain to JAM it into the socket, as the big block of rubber inhibits proper seating.
wait a quarter minute
attempt to power on.
If no joy, examine the button battery half-hidden behind the graphics card. Remove it to measure the Voltage. A new battery should not cost over US$5, and measures a little over 3 Volts. BR-2032 is used in garage door opener controls and car door locks controls. The geeks at Radio Shack can measure it for you. -
Just tried installing an update to OSX Snow Leopard. Prior to trying to update OS, I was running V 10.6.3. During installation, it locked up. Although the screen tells me that the installation will be completed in less than one minute, that was two hours ago, and the computer won't permit me to shut it down via the power button, as I get an error sound. What do I do now? Help!
Hold the power key till it shuts down, it may take a little while, try holding it thru the warning.
Then if it shuts down restart and open Safari/Preferences, General tab, and set "Save Downloaded Files to:"
Select desktop, if desktop is not available in the the drop down menu, click other, then select Desktop from the column from the on the left.
Then download this:
http://support.apple.com/kb/DL1399
This will download the "stand alone installer"
Click on the installer pkg and follow the prompts.
Hope this helps -

Hi there. If you have 10.9 Maverick you can get in recovery mode By using /command r Option R or Option. Then you came click on the link to go to disk utilities and repair your disk or do a reinstall of you operating system. I think the screen you are seeing is the recovery screen. Here is a hot of what it looks like. You will have to scroll down a little to see it.http://osxdaily.com/2013/11/05/downgrade-from-os-x-mavericks/ http://support.apple.com/en-us/HT4718 This link tells you what you can do.

Experiencing similar issues on both imac and power book: after replacing an original airport extreme with a new airport extreme both computers display a black box msgs that reads: "...turn off your computer by holding down the power button and or the reset button for a few seconds and then restart your computer."...
one of the printers are usb'd to the imac. The printer is not "seeing" the imac nor will it print wireless from the powerbook which was the norm prior to the upgrade on the airport extreme.
Upon restart, the imac does not "see" the wireless keyboard or the mouse until it is "found" again.
At this time the imac or the powerbook can get on line.It sounds like your computer is getting Kernel Panics. Please look at About "You need to restart your computer" (kernel panic) messages and if the message seen on your display is like the one in the link then you have confirmed you had a KP. KP's can be tough to track down because they can be caused by software or hardware. The first place to start is to post the complete crash log so we can look at it, often there are clues in the log. You can find it at:

I could not start up my MacBook Air tonight, even after making sure the battery was fully charged. I have had it for 2 1/2 weeks and downloaded Mountain Lion 2 days ago. This has never happened before. It started when I held down the power button and accidentally hit the F12 Key. Is this a problem and what should I do about it?
call AppleCare.

It's new and under warranty. That's the reason to go to the Apple Store.

My Mac Mini was not sending a signal to the monitor. I powered down using the power button and now it will not start. When i power up I get a strange 2 tone sound, like a warning alarm. The fan starts, and the light comes on, but no screen.
I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.
Reset SMC no changeRun the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

when i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway. -
I can't turn on my MacBook Air despite trying to hold down the power button and using the SMC method. BTW my battery charger lights up to a green when plugged into the laptop.

yesterday for the first time i turned on my macpro 2011 model and i got a crazy gray screen with lines all over it ,so i held down the power button and turn off then restarted and all was ok could someone help me with this,what caused this shut down. werd
Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic. -
My iPod touch 5th Gen. wont start up past the apple logo,ive tried holding the power button and the home button,and it wont start up. What do I do?!?!
Try the remaining items of:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
