MacBook Pro screen randomly turns black on me for no reason while I'm using it? What's wrong with my MacBook?

I have a MacBook Pro from 2009 and the screen randomly turns black on me for no reason while I'm using it? It takes anywhere from 5 seconds to 1 minute to turn back on and no matter what I do it just has to fix itself so idk if it is going in to sleep mode or what. Anyone know the issue? Thanks.

Run through them and stop after #16 or if the problem stops, or if something tells you something severe (like hardware test giving a error)
If you can backup your personal data off the machine, you should do that first.
Hardware issues we cant' fix, only a few things may fix it.
Software issues we can fix, but right now we don't know what is causing your issue as we can't see it obviously.
So your going through a process of elimination to try to give us a clue what's the problem and then we can advise a course of action.
If you feel this is way over your head, then just make a appointement with Apple and/or your local PC/Mac specialist.
We are only other uesrs here, helping other users.

My 13 in MacBook Pro screen randomly goes black. It was purchased in 2010. It's a 10.6.8.

My 13 in MacBook Pro screen randomly goes black. It was purchased in 2010. It's a 10.6.8. It started just recently. The only thing I can think of is is that my 7 year old son played an online game with the computer. I did check the "hot corners" settings and that is not the issue. When the screen goes black, I generally end of foce shutting it down with the power button.

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

Macbook pro late 2010 battery at 24 cycles for 15 weeks computer and capacity is already 93%, anything wrong?

macbook pro late 2010 battery at 24 cycles for 15 weeks computer and capacity is already 93%, anything wrong?

How many cycles depends on how often you drain the battery down low and then recharge it to maximum, ideally use it a little less on battery and a bit more on mains and the cycle count will slow down. Every couple of months you need to re-calibrate the Battery for best long term results.

Go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report in 10.7), then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information back here.
Also it would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report in 10.7).When System Profiler comes up check the Model Identifier.

Why does my mac screen randomly turn black

Randomly when I use my imac my screen just turns black! it scares me and its reallllyyy ANOYING!!!!!!!!!!! I JUST UPDATED TO MOUNTAIN LION

When was the last time you seriously vacuumed out the air intakes (the bottom grill work and small vent under the stand) to ensure that it is cooling properly?

What is wrong with my Macbook Pro? (distorted screen, beeping, slow)

I have a late 2012 Macbook Pro (13-inch) that I got from Best Buy. It worked perfectly fine for a year, but then went crazy.
First, it started shutting down here and there, and icons bounced a lot in the dock. Then, one day, I googled something and it froze, then flashed a strip of multicolored barcode-like lines. So, I shut it down and it overheated then began to beep 3 times and flash a light.
I brought it in and they just wiped the hard drive. Then, it happened again while I was watching a video only a short time later. I was going to re-seat the RAM myself but the inside of the computer looked all messed up. I took it in and they gave me a new LCD but it has a dead pixel now. It worked fine for 1 month after that.
Then, I was using the laptop on my bed and it shut off randomly a couple of times while I was on Facebook and started beeping. I rebooted it and tried to fix it but it happened again the next day. I brought it back to Best Buy and they said it was hot and sold me a $20 cooling pad.
That worked for a few days, then I was watching TV online and it happened again. I brought it back to Best Buy and they replaced the RAM. Now, I was watching something online and it happened yet again. I was able to reboot and it worked okay now for a couple of hours but it did freeze again and I had to shut it down.
Everytime I go to Best Buy, they tell me "If we have this issue 1 more time, we will replace your computer." But, then, they say the same thing every time and that it's their policy. I have paid for Office now and only have 1 download left. Also, this is ridiculous because I'm a student and I've had my Mac gone for 2 weeks at a time at least 3 or 4 times. When this happens, I get stuck using my iPad and can't use flash so I've spent tons of money of apps for flash and other things to make my iPad functional.
Can somebody just tell me what's wrong with it? It "passes the hardware test" every time and the Geek Squad keeps asking me stupid questions like "Did you check your internet connection and reset your modem?" When I asked them the first time to do a PRAM test, they didn't know what that was and asked me to go on iTunes or clear my cache or something like that.
I have had a bad experience with them altogether. I got my Macbook for $500 because I had a PC before that I paid $700 for and it eventually broke. They were unable to repair that one because the hard drive had failed, although they had previously been convinced that I needed to uninstall my Norton to fix that problem.
Sorry if I'm ranting, but my Macbook is like a child to me (not to sound weird) and I'm sick of this problem. It's working fine at the moment but I know this will happen again randomly like always.

If you're able to boot, launch the Console application by entering the first few letters of its name into a Spotlight search, and select the most recent panic log under "System Diagnostic Reports." Post the contents -- the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID” and "Kernel UUID," two long strings of letters, numbers, and dashes in the header and body of the report. Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you will see "Safe Boot" on the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all, including your login items.

What's wrong with my Macbook? It randomly switches off. Could it be the charger?

Hi..so I've had my macbook pro for almost two years now. No problems with it, but I find that their charger cables or headphones are weird as they always break for me one way or another. My charger started breaking a year ago, still works, just the green wires at the top have come out so I taped it. The charger still works. Anyway..today I was on my macbook, it was charging and it was on about 65%, then when I moved it somehow (I was adjusting it on my legs cause I was sitting down), it switched off. The charging light went off and the charger wouldn't work. After about 10 seconds I could switch my macbook back on. When the home screen came on, my date and time have been reset and I was disconnected from my internet and my background changed. I put everything back to normal and then after unplugging the charger and playing around with it I connected it to my macbook. It worked again. Now the same thing happened again. I somehow moved it and it switched off! What's wrong with it ? Can it be because of the charger or some virus or something? I tried checking the logs and Crash Reporter but nothing came up. Can anyone help? thanks

Let's address the breaking cable issue first. To unplug any cable, you need to grasp the connector shell, and pull. It is wrong to simply grab the cable wire, and give it a yank. For the other issue, try perfoming SMC and PRAM resets.

I need help figuring out what is wrong with my Macbook Pro

I have a mid 2012 Macbook Pro with OS X Mavericks on it and for the past few weeks it has running VERY SLOW! I have no idea what is wrong with it, i have read other discussion forums trying to figure it out on my own. So far i have had no luck in fixing the slowness. When i open applications the icon will bounce in dock forever before opening and then my computer will freeze with the little rainbow wheel circling and circling for a few minutes... and if i try to browse websites it take forever for them to load or youtube will just stop working for me. Everything i do, no matter what i click, the rainbow wheel will pop up! The only thing i can think of messing it up was a friend of mine plugging in a flash drive a few weeks ago to take some videos and imovie to put on his Macbook Pro, he has said his laptop has been running fine though... so idk if that was the problem. Anyways, could someone please help me try something? Thank you!!

Is it possible to disable all funktions in the loocking screen, even turn off button (also for security reasons if lost cannot be turned of until code entered or battery low....)?

Hello, is it possible to turn of all functions in the locking screen? even the turn off function (also for security reasons / so that it cant be turned of while using find your iphone?)

Yes of course, i know... havn`t lost it but however makes it harder to steal (get bettery out of it or find an area with no cellular connection which are well developed here isnt that easy as just to turn off the device).
It only makes it marginally harder to steal. There are many ways to defeat Find my iPhone; turning it off is only one of them. Others:
Remove the SIM
Wrap in aluminum foil
Drop in a shoplifter's bag or backpack that is metal lined
Run the battery down
Connect to a computer and restore the phone
Requiring a passcode to turn the phone off would also make the millions of users whose phone was not stolen very annoyed that they can't easily turn off their phone.

What is wrong with my Macbook?

I dropped my macbook (2007 model) and the screen is so cracked that I can not see anything. I got a mini-dvi - vga cord and plugged it into a monitor, but when i turn it on, it just goes to the mac background, and will not show the login screen. What is wrong with it?

it's putting the monitor as second display, so the login screen (i'm guessing) is only displaying on the first—main—screen, the the one that is cracked.
restart the macbook and don't touch anything. when the background appears on the secondary monitor, you know the login screen must be up on the first monitor. so type in your username, hit TAB once, then your password.
you should be able to log in now. then follow these instructions:
(bare in mind i'm running 10.6.8)
1) press ALT+F2 to open up displays in system preferences.
2) you should be able to see a dialog open up in the secondary monitor
3) if this has a "Gather Windows" button, press it
4) if step 3) works, you should be able to switch around the main displays, or turn on mirror mode, or whatever
