While working on PC side, my screen went dark and my Macbook Pro has been emitting a loud buzzing/humming noise. How do I reboot? Am I totally dead?

Help, I was working on my pc partition, using quick books and my machine suddenly freaked out. Screen is dark, backlit keyboard is lit and it is emitting a LOUD humming/buzzing. I can't reboot, turn it off, nothing. I unplugged the power chord in hopes that the batter will run out but what the heck happened and is my machine completely gone? Is this under warranty? I bought this thing in august of 2010 so it's not yet a year old.
HELP! HELP! HELP!

Hold down the power button and it will shut down. Have you not read the User Guide? (Chapter 4).

Screen goes dark on a MacBook Pro

Occasionally the screen goes dark on my MacBook Pro (2009). It is running Mavericks. The computer is still running, just no picture. After restarting it a few times the screen will again be working. Any suggestions?

Hi M149,
I apologize, I'm a bit unclear on exactly what model projector you are using and how you are connecting it to your MacBook Pro. You may find the troubleshooting steps in the following article helpful:

My MacBook Pro has been having difficulties at startup. It sometimes locks and doesn't get past the white screen. It has also locked up several times and gotten a green stripes across the entire screen. What is causing this and how do I fix it?

You don't, take it to Apple for repair.
This might interest you if it's too old to fix.
My computer is not working, is my personal data lost?

My macbook pro has been shutting off on its own. The power cord "shuts off" (does not work) simultaneously. Does anyone know what is wrong? or what could be the problem?

When my mac finally turns on the date/time is reset a windows pops up saying, "Your computer's clock is set to a date before January 1, 2008. This may cause some applications to behave erractically."

MacBook Pro has been acting up for a while.

My MacBook Pro started acting up at the beginning of this year. The first thing I noticed was a clicking noise that came from the top left corner. It wouldn't happen often, but over time it started to happen more frequently. Then, a few months later, it started having other problems. Infrequently, certain apps would not work normally or quit working altogether. Chrome and Firefox didn't work at all. I would have to restart my computer, and then everything would work again. This problem gradually happened more frequently as well. I used Smart Utility which told me my hard drive was about to fail or failing. I replaced my hard drive myself and this seemed to mostly fix the problem. But I do remember the apps not working problem happening one time soon after I replaced my hard drive. It was probably about 4 or 5 months ago that I replaced my hard drive and I had the apps not working problem probably about 5 times since then (which concerns me but is still a lot less frequent than before I replaced my hard drive). And now when the app problem happens, I can't even shut down or restart my computer. It does nothing when I click shut down or restart. I have to hold the power button to turn it off. I never had this problem before I replaced my hard drive when I had the apps not working problems. And I used Smart Utility recently and I believe it told me my hard drive is failing. It's hard to judge, but it seems like my computer has been running a bit slower the last month or so (getting more of the spinning beach ball icon). Also, every so often, the clicking noise still happens (if I remember correctly from replacing my hard drive, the hard drive is located in the bottom right corner, so I'm not sure if this noise could be the hard drive?). I'm skeptical to believe that I have a hard drive problem again since it's a completely new hard drive I put in 4 or 5 months ago. But at the same time, the problems seemed to be fixed temporarily by this new hard drive but are possibly slowly coming back.
I was waiting for the apps not working problem to happen again so I could write down some of the symptoms, and it just happened a few hours ago. So I'll explain some of the symptoms:
When I open Firefox, I get an error that says
"Close Firefox
A copy of Firefox is already open
Only one copy of Firefox can be open at a time."
After I click OK, Firefox quits.
When I open Chrome, it comes up for a second, and then quits.
The dictionary app on the dashboard works (I can type in words, and dictionary entries for the words come up). This was interesting to me because I was intially thinking if it's a hard drive problem, the dictionary wouldn't work. But then I figured that maybe the dictionary gets it's data from the internet, but I'm not sure.
It seemed that I could open any picture (with the Preview app) that I could access, like pictures on the desktop and pictures directly inside the main "Pictures" folder. Folders contained inside of the main "Pictures" folder that normally held files now showed no contents. Other folders that also "showed" no contents included the "Documents" and "Music" folders. The other folder that did show contents was the "Desktop". My guess about these issues is that the items that were shown and could be accessed were stored in RAM, and everything else wasn't able to be shown or accessed because the hard drive data couldn't be accessed for whatever reason.
And then I never knew whether or not I would have been able to shut down or restart my computer this time because when I clicked on the "Public" folder, the computer did the spinning beach ball thing and I couldn't even get to the menu to restart or shut down. So I held down the power button to turn it off, turned it back on, and here we are. I'm on the computer right now and it works OK.
I'm thinking my best bet is to take it to an Apple store, but I wanted to check and see if anyone has any ideas on what the problem(s) could be. It also has some other issues, like the computer won't charge unless I jiggle the connecter around until the charge symbol on the computer turns into a lighting bolt. And if I click on the battery symbol, it says "Service Battery". If it helps, I got my MacBook Pro in 2009.
Thanks,
Ryan

It may be that your hard drive is either failing again or that the hard drive bay SATA cable may need replacing. And if you're getting a "Service Battery" anyway it's probably best to take the machine into your local Apple Store or an AASP and get a free diagnosis and estimate for repair. I would specifically ask that the SATA cable be tested so that you can tick that off the list of culprits.
Good luck,

HT3964 For the past several months my MacBook Pro has been shutting down. I get horrible video with marks and striations acress the laptop screen and an additional monitor and the weird video problems until the multilingual notice comes up saying to shut

I used two monitors, and several months ago the MacBook Pro started crashing frequently. It seems like it might be overheating. Sometimes the disks seems to race. I leave the computer on most of the time and it sleeps when I am away, but when I come back in the morning it will have colored striations across both screens, and soon the multilingual announcement comes up that I have to press and hold down the power key.
Also, when using a progam like Skype video, the video goes insane frequently, with Skype windows freezing, video freezing, Skype window cutting in half, and eventually the computer crashing.
It seems to be a video problem.
What do I do?

I would take some screen shots of the anomalies and take the MBP to an Apple store genius bar. I you cannot reproduce the display problems, the screen shots will at least give them a start point for an analysis.
Ciao.

My macbook pro has been stolen and i had icloud and find my mac installed. If the thief was to wipe my harddrive and use internet recovery, will my find my mac still work?

Hey guys, so I recently had my macbook pro stolen. I had my find my mac turned on and i was wondering if i could still track my laptop if the thief wiped my hard drive and the recovery partition, but if they reinstalled the mountain lion osx from the internet recovery would that erase the find my mac feature? Thank you guys for all the help. Just doing what i can to try and retrieve my laptop. Thanks

Yes, if the wiped the drive Find My Mac would no longer work. The can't reinstall Mountain Lion without your Apple ID or an Apple ID of their own.

Is anyone else having frequent crashing with iphoto 11 while editing photos? We have 2 imacs (2007) and 1 Macbook pro (2010) and all three exhibit the same spinning rainbow wheel and crash after 3-7 edits.

all macs are running 10.6.7
all have 4gb ram
I saw some posts about the early intel nvidia issues, but the fix mentioned was 10.6.7 which we already have.
same library worked perfectly before iphoto 11.

My macbook pro has been freezing up randomly and barcode looking lines go all across the screen. Does anyone know if Apple had a recall on a 2012 model macbook pro that would explain any of this?

Does anyone know what I can do about this? I'm pretty certain that I didn't do anything wrong, and I already got it checked for viruses and it is not that.
Thank you so much,
~Poor college kid trying to get by.

Hard to say, you'd have to shop around. Check first with authorized service providers - https://locate.apple.com/au/en/#
If they're not authorized, make sure they give a warranty on the repair and hopefully have some good reviews on Google/Yelp etc.
Also make sure you test it when you get it back, it's common for the replacements to fail unfortunately (from Apple at least, probably anywhere).

Screen went dark/dim. How do I fix it?

2nd generation iTouch.
Screen went dark/dim (can barely read it under a light).
Any ideas on how to fix it?

Try:
- 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.

Screen Going Dark and Then Black

Although my computer is not an Intel, I have been following the discussions here because of the flickering problem. I intend to buy the i7 when the next series comes out. I posted my problem on the regular iMac G5 forum but received a very limited response specific to the problem.
My iMacG5 is the initial model and will be 6 years old this coming October. I have not had this problem before.
One day, the computer screen went black. Took it to Apple. Either mother board or power supply. Changed power supply and computer worked but technician damaged screen and bezel. Apple changed screen and bezel front and back. Came home, working fine but notice very slight and quick flickering sometimes. Suddenly, screen went dark and then black. The F14 and F16 keys could not change it. Took it back to Apple but problem could not be repeated. At home, problem occurs. Right now, screen at brightest but then brightness cuts back significantly but screen is as usual except darker. Computer can be used but darker. After a while, screen would go black. Can still hear computer. Fans normal speed. Light at lower right still blinking but when touch space bar or mouse, light at lower right goes off and computer stops but still black screen. When I unplug cable from back and wait 15-30 minutes and restart, screen bright again but then darkens and cycle repeats itself. Screen Saver not on. Beside the bezel, only items change are the power source and the screen.
CHECKED CONSOLE AS BEST AS I COULD. ON TWO OCCASIONS FOUND FOLLOWING NOTICES: BOOT CACHE.PLAYLIST: UNKNOWN ERROR: -1. ANOTHER ONE: LOCAL HOST KERNEL [0] APPLE SM_SHUTDOWN CAUSE = -100. THESE MAY HAVE SOME SIGNIFICANCE ALTHOUGH THERE'S A LOT MORE THAT I DON'T UNDERSTAND.
HOPE SOME OF YOU CAN HELP. Thanks.

You should visit your nearest Apple Store as soon as possible for getting it done perfectly !

Macbook pro retina start to make loud fan noise and work slow

I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.

If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964
