My macbook pro keeps blacking out

My 13" macbook pro keeps blacking out when I'm using it and the only thing on my screen is the cursor, could you please tell me how to resolve this problem?

Go step by step and test.
1. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own"

Why does my MacBook Pro keep blacking out randomly?

I just fit this brand new MacBook about 3 weeks ago off of Amazon. About a week after I first used it, it started to blackout randomly & take me to put my password back in. I would start typing my password, then it'd do it again. Sometimes. I tried changing the settings for the energy saver, but it still continued to do it. It might happen minutes, seconds, or hours between. It's frustrating when I'm writing papers or online or doing what I need to do for school. It doesn't erase anything or turn off, but it's still not functioning like it should be for the money I paid for it. If you could help me out, if greatly appreciate it. Thank you!

While I'm not sure what the problem is, it sounds like your machine blanks out unpredictably, or exhibits general problems that are hard to describe. Something seems to be wrong, anyway
You may want to visit your local Apple Store/Genius Bar. It's a good educational resource, in case you just need to learn about your unit's features. But if there's a problem, they're the place to get it fixed. You're going to want to document the issues, specifically, and preferably so that an Apple employee can duplicate the problem on your machine.

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Macbook Pro Retina blacks out for a few seconds at a time

I have a new (2-3 weeks) Macbook Pro 13" retina display. A few times since I've had it, the screen went black for about 10 seconds and then came back. Any idea what's up with this? Is this something to return the machine for, or is a software issue? Has anyone else had this happen?
Thanks!
Stacey

Mid 2010 MacBook Pro 15" Blacks Out Without Warning

Quick Summary of Problem: My MacBook Pro is currently shutting down without warning. It would be more accurate to say that the screen goes blank but the machine remains on as can be heard by the fan. Nothing resolves it without powering down and restarting. It has occurred when attached to a power source or via the battery.
My machine specs: Mid 2010 MacBook Pro 15” with 500GB hard drive, 8GB RAM, Intel HD Graphics/nVidia GeForce GT 330M with 512MB, anti-glare 15” screen with max resolution 1680 x 1050). Running Snow Leopard 10.6.8 with 2013-001 Security Patch installed.
I have AppleCare which commenced when I first bought the machine in July 2010.
System Profiler says my battery condition is ‘Normal’. Cycle count: 610.
Detailed Summary of Problem: Back in January, my MacBook Pro shut down several times without warning. Each time, I was creating selections on high resolution imagery in Adobe Photoshop CS5.
Not long after, I saw the ‘MacBook Pro SMC Firmware Update 1.7’ relased on Feb 12 (http://support.apple.com/kb/DL1633) and installed it via Software Update. By coincidence or not, my MBP behaved much better afterwards and the seemingly random blank screens requiring a restart disappeared.
But then I installed the ‘Security Update 2013-001 (Snow Leopard)’(http://support.apple.com/kb/DL1642) via Software Update and that’s the only thing I can really remember changing to my system. Since then, the black-outs have reappeared. As before, I was usually using Photoshop and working with high resolution imagery. However, one time the machine blacked-out, I was simply doing a two-finger scroll on the built-in trackpad whilst in Chrome (Version 25.0.1364.172).
The blackout has occurred twice now not being connected to power, and twice with it being connected to a wall socket. Needless to say, I lost work in Photoshop (even though I’ve begun to save more regularly) and now it feels like it’s a ticking time bomb and I don’t know when it’s going to go off.
One thing I’ve found rather odd is that in the crash log, the kernal version doesn’t seem right for Snow Leopard:
Kernel version:
Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386
System model name: MacBookPro6,2 (Mac-F22586C8)
The full crash log can be found at the bottom of this post.
Fixes I’ve tried:
1) Resetting the NV-RAM has done nothing. (was suggested
2) I’ve tried reinstalling the ‘MacBook Pro SMC Firmware Update 1.7’ by downloading the manual installer from Apple, however it now says ‘Alert: This software is not supported on your system’ which in a way makes sense given I’d already applied the firmware update, but a more accurate message along the lines of ‘This firmware update has already been installed’ would be more reassuring.
3) If all else fails, I could resort to copying over a backup I created with Carbon Copy Cloner, which was done before I reinstalled the 2013-001 Security Update for Snow Leopard. But that’s a bit of a headache too, because my documents I’ve updated since the backup will be out of sync. Another reason this isn’t a great solution is that I can’t take advantage of the 2013-001 security update, nor future ones.
Any suggestions? There’s probably no good time for something like this to happen, but this is a particularly bad time – I’m currently beginning design and finished art freelancing and brushing up on some applications I haven’t used in years. Nor am I going to make an impression meeting with recruiters without my folio being presented from my MBP.
I’ve already booked a Genius appointment 2.5 days from now, but all help and ideas greatly appreciated!

I am sorry. The page that came up has an AD for issues with a 13" MacBook Pro in the corner. I read the AD as if it were part of the article and assumed the whole page referred to the 13" model. My Mistake.
However, the issue described by TS4088 is not a soldering problem. It is a Latent Defect -- a flaw built into certain batches of those chips from the day they were packaged and installed.
If your Mac fails the VST test used to detect this Latent Defect, re-flowing the solder is likely to have NO EFFECT on its performance -- the solution is the remove the defective chip and replace with a good one.
There certainly can be problems in these and other Macs where a re-flow would be beneficial. But I caution Readers not to generalize your solution to Macs that are known to fail VST. Re-flow alone will not solve the Latent Defect problem.

Macbook Pro screen blacks out keys stay lit

The gist of it is in the subject
Pretty much without warning, does not have a preference for type of application being ran, the screen will completely black out. If sound is being play it either stops or begins to skip. The keys stay lit. The only way to bring it back is a hard restart.

Which model MacBook Pro do you have (e.g. "15" late 2011")?

Why does the sound on my 2011 MacBook Pro keep dropping out?

Over the past couple of days the sound drops out on my 2011 MacBook Pro. It start about 30 minutes after I've switched on the computer and then keeps on happening every 3-4 seconds. What could be the problem?
I've got a 13" MacBook Pro early 2011, 2.3 GHz.

Hi A,
You are still covered under the Apple warranty. I would contact AppleCare or make an appointment at a "genius" bar.

Macbook Pro randomly blacks out

My macbook pro 13' mid 2011 model had recently (past month) experienced some screen suddenly blacking out issue (it goes to sleep randomly). I searched the forum and apple's support center, and they only address the issue for 15' 2010 model, does anyone else have the same problem, and what can I do other than brining my computer back to the Apple Store?

Below find the article from Apple support site. It may apply in this situation.

May be you should take the computer to the Apple store.
Best.

The internet on my macbook pro keep cutting out in OS 10.8..What to do?

Hello,
I purchased a new macbook pro about in early September and ever since I started using it in my home, the internet cuts out constantly. I was using a aiport to connect wirelessly and then swithced to a router provided by my internet company which is Time Warner. I have the fastest package they sell but nothing seems to help. The internet cuts out after about 5-10 minutes everyt time I use the internet and download speeds are nowhere near what they should be for the package I have.
I'm using the newest OS (10.8.2).
Any help is very much appreciated!
Thank you

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers
    Make sure that Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
6. System Preferences > Sound> Sound Effects
    Play sound effects through:
   Select "Internal speakers" and then back to "Selected sound output device".

MacBook Pro randomly blacks out and have to shut down

My MacBook Pro's screen will go black randomly and the keyboard is still lit but the only way to bring the screen back is to power it down via the power button. It happens all the time and I don't know what is wrong with it!

Macbook pro screen blacks out

I just bought my first Mac. I have noticed since I received it a couple weeks ago, that the screen blacks out occasionally. I am pretty sure this mostly happens when I am in Safari. Any ideas why? This will happen with my ipad 1 every once in a while too. It will black out and revery back to the home screen.

You should take it into the store as it certainly could be a hardware problem. In my case, however, i didn't notice it when I was on Lion, noticed it on ML, and then haven't seen this problem again since downgrading to Lion.
Since your problem is intermittent, it might be hard to produce at the store. So, you might want to try to capture it on video before you go to the store so you have something you can show them.

My Macbook Pro keeps restarting out of the blue

It's been doing it for a couple of weeks already. As far as I can tell, its very random. It happens at any time, ive tried to see if its a specific program, but it restarts at random times. I did an SMC reset and that didn't do anything. Lastly, i wiped my hard drive and restored my laptop to brand new and 10 minutes into running a fresh install (without any of my data transfered back in yet) it did it again.. Anyone got any ideas??
Ps. the hard drive is only 6 months old, and when the old one started going bad, it didn't present this type of problem.

Oh, well that's a different story - you may have the dreaded 2010 model failing NVIDIA card - see http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US.
You should be able to get a free logic board replacement to fix the issue. Use the "Contact" link on the site that I provided and get the ball rolling!
Good luck,
Clinton
