MacBook Pro 13'' (late 2011) blacks out all of a sudden?

It's been a couple weeks now.. all of a sudden while browsing the internet or during other regular stuff, the screen of my Macbook blacks out. I press Esc several times and also the keyboard lights out. Then it starts working back normally as if it went on stand-by. This started after a while I installed Mountain Lion 10.8.2 and at first I thought, having overwritten the previous OS, that the whole thing might depend on that. But then I completely re-installed the system and it happens at least once a day. Anybody else experiencing this and has anybody found a way out of this thing?rn is that
My concern is that it might be a symptom of a hardware malfunction :S

  • MacBook Pro 15" Late 2011 Problems with iMac 27" Late 2009 TDM

    Hi,
    I just got problems with my iMac 27" Late 2009 (Mini-DisplayPort) and my MacBook Pro 15" Late 2011 (Thunderbolt).
    When I try to use my iMac as external monitor for my MacBook, there are massive glitches and graphical bugs on my second screen.
    I bought a MDP-to-MDP wire from Belkin which works perfect on other computers.
    I tried these things:
    - Disconnected MagSafe from MacBook + unplugged all USB devices + switched graphics to discrete.
    - Shut down all computers ... then booted MBP, iMac and triggered CMD+F2
    - SMC, PRAM reset on both devices
    The cable works, because:
    17" MacBook Pro Late 2011 works perfectly on my iMac screen with my Belkin wire!
    I connected my MacBook Pro 15" to a 27" Cinema Display and it works flawless.
    After that I plugged it out and tested it again with my iMac screen -> suddenly it works.
    Retriggering CMD+F2 or replugging breaks it again with massive bugs.
    The MacBook Pro 17" is on 10.7.2, 15" is on 10.7.3, but I also tried to trigger dual screen in 10.7.0 setup with the same issue.
    Maybe its a problem with the internal 6750M of my MacBook Pro 15"?
    The 6770M of the 17" is working well.
    Sample Video:

    All updates/firmware updates of iMac and MacBook Pro are installed.
    Any solutions?

  • Macbook Pro 13" Late 2011 hard drive fails, how to replace hard drive?

    Hi!
    I have a Macbook Pro 13" Late 2011 (OS X Mountain Lion v 1.3.18 (352.4). I tried to install OS X Mavericks but it showed this error message:
    "This disk has S.M.A.R.T. errors. This disk has a hardware problem that can't be repaired. Back up as soon much data as possible and replace the disk."
    The laptop was still doing fine so I didn't do anything. Then it started to act funny: iPhoto stopped working, hangs when I watch video streaming, and it started to run really slow. I only use the laptop's basic features- internet, watching movies, editing using iMovies so it's really strange for me that the hard drive failed all of a sudden.
    I called Apple support and a kind fellow tried to troubleshoot it, thinking it was only a software problem. In the end, he said I need to bring my macbook to the service center and have the hard drive replaced. I know it will cost a lot so I want to replace the it myself.
    Here are my questions:
    1) Can this problem really be solved by just replacing the hard drive?
    2) Can I use SSD this time so my Macbook can run faster?
    3) What SSD is recommended for my late 2011 Macbook 13"?
    4) I don't have the installation disk, can I still install the OS X Mountain Lion? How?
    I am looking for other sites as well but I hope this community could share some tips too.
    Thanks a lot!

    I've switched out the hard drive on my Late 2011 model several times and I've never disconnected the battery cable.
    In my "Opinion" it is not necessary to do that. Not sure if it is or not recommended by Apple.
    EDIT:
    I just looked at my User Manual, PDF I downloaded from Apple, and there is no mention of disconnecting the battery.
    Here's a link to the manual for my model.

  • Notification center stops working on Macbook pro 17 late 2011

    I had several problems with Mountain Lion on Macbook pro 17 late 2011 model.
    #1 Notification center stopped updating
    #2 Worst battery backup had dropped significantly , it appears that the laptop needs to be plugged in to the socket at all time. Current backup is around 2 hours.
    Anyone else got similar issues ?

    85w apple charger stops charging the Mac
    I think your assumption that when the amber light goes out, the magsafe is malfunctioning is not correct.
    Some users have observed that if you push your Big MacBook Pro as hard as you can, it needs all the power from the power adapter (and possibly more from the battery) just to keep running. Thus, the charge indicator on the magsafe will go off Amber. This is weird, but is not a malfunction.

  • MacBook Pro 17" (Late 2011) Graphics Card

    Hello Community,
    I've researched this community, and found some relevant posts to the following question. However, the answers I found weren't completely satisfying. So, I'm posting my own on the subject to help me and others.
    I have the following:
    • MacBook Pro 17" (Late 2011, MacBookPro8,3) 2.5 ghz Quad Core i7/512 SSD/8 GB RAM
    • Graphics Card: AMD Radeon HD 6770M with 1 GB VRAM and Intel HD 3000 Graphics
    I know desktop models can be upgraded, but I can not afford the one I need at the moment. I am aware that many Apple laptop graphics cards can not be upgraded. Can this particular AMD Radeon graphics card be replaced and upgraded?
    If it can be replaced and upgraded, any suggestions on the best graphics card available? AMD has some nice upgrades.
    The card is nice, fast, and I'm not unhappy with it, but I run graphics and multimedia applications, and could benefit from the newer cards available.
    I appreciate your input community.
    Thanks,
    Greg

    About the only time you can upgrade a video card in a notebook is if that model notebook came with a better video card then what you ordered. At a later date if that better video card become available on the used market you could by one and replace the original as it was made to fit in the same model.
    But it is almost impossible to buy one from the original manufacturer. Especial during the current production run of that model.
    In your case the model you bought has the best video card available in the new line of MBPs. So there is no better card that would fit in your system. Whether the new models that will be coming out later this year will use a better video card and whether it would physical fit in your model is unknow.
    But all of what I wrote above doesn't really matter as with all Macbook Pros the video card and CPU is Soldered to the logic board and can not be replaced. If either fails the complete logic board needs to be replaced.
    The only things that can be easily replaced by the user in a Apple Macbook Pro is the RAM, hard drive and DVD drive.
    All other parts Apple does not sell to the general public.
    So your only option is if the newer models have a better video card is to sell your present system and buy the new model.

    7. After this events (events 6). Command R, Command Option P+R, Command Option F+O, all other shortcut wont work?
    Please help !!!!!!!,

    I suggest that you boot the MBP OPTION+COMMAND+R.  The display should show a revolving globe.  This will connect you to the Apple servers and will allow you to install the original OSX.  You will need a solid Internet connection.
    Ciao.

  • I have the new macbook pro from late 2011. when i try plugging my cannon gl2 into the mac via firewire 800 it does not show up in iMovie as an option to import from. i even have gone into my settings on the camera and changed it to vcr.

    I have the new MacBook Pro from late 2011. "the one before the new ritina display" i have a cannon gl2 video camera which is mini dv. when i plug it into my mac via firwire 800 it does not show up in the iMovie. i have set the settings on the camera to vcr mode and changed it to av->dv out. when i click on the import from camera on imovie it doesnt even show my camera in it. it just gives me the option to import video from my facetime camera. the camera is turned on the wires are connected i know for fact that its a firewire and not a usb. i know what they each look like. i bought the firewire cable and it was marked down cause it was an opened and used item. would it be possible that it could be deffected and if that is not the reason what other options do i have?

    I would say that odds are high that you have a bad cable. Maybe that is why they returned it.
    I would suggest trying a different firewire cable.
    You can find Firewire cables inexpensively at monoprice.com. You need a 4 pin to 9 pin firewire cable.
    Here is a link.
    http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10301
    Other things to check:
    Is your camera plugged in to wall power (not to batteries only). Must be hooked to an AC power source to import.

  • MacBook Pro 13" Late 2011, 16GB RAM and Apple Premium Service Center

    Hello all,
    My dad has a MacBook Pro 13" Late 2011, it came with a 4GB RAM. When he got Parallels and installed Windows 8, 4GB RAM were not enough to even deal with Safari so he had to buy 16GB RAM from Cruical. Today when he went to Apple Premium Service Center here in Qatar (51 East) they refused to install the x2 8GB RAM and only installed one of them. They kept warning my dad that installing the whole 16GB can cause issues with the MacBook Pro HDD and can make it go faulty. I wanted to ask if installing RAMs can pose the HDD life to any danger. Because my dad uses his Mac for work and wouldn't like to lose any of his files against small additional speed.
    Thanks.

    its very easy to do, here are step by step instructions with photos

  • Macbook pro 13" late 2011 stuck up at apple logo and spinning wheel, changed HDD problem still exists

    thanks

    Have you tried booting into the Recovery HD and running Disk Utility and checking to see if the HD needs repairs?
    Restart holding Command + r and at the recovery screen select Disk Utility. Then select Macintosh HD and click  on 'repair disk'. If anything gets altered click on repair disk again until you get a clean pass. Restart as normal from the Apple menu. More info here about the Recovery HD:

  • Transcend 1TB SSD in MacBook Pro 15" (Late 2011)

    Hey Guys,
    I just bought a Transcend SSD 1TB for my MacBook Pro 15" (Late 2011) with OS X Yosemite 10.10.2.
    I got it for a good price but now I'm unsure if I could use it.
    The SSD i bought is the TS1TSSD370. For more Info click HERE.
    My questions are:
    1. Is the SSD I bought compatible with my MacBook?
    2. Is it a good SSD to use with a MacBook?
    3. Can I use a 1TB SSD? Because on the Apple Specs Site for my MacBook Model it's doesn't say anything about a 1TB SSD.
    4. Do I have to consider anything special when using this SSD?
    It would be really great if someone could help me out!
    Thanks in advance!
    Max

    I use the Carbon Copy Cloner method as outlined by BobRz above.
    I'll be installing another SSD (higher capacity) whenever it gets here (Dec 3-Jan. 03) and I'll install the new SSD in my MacBook Pro first and then using my old SSD in an enclosure to transfer data.
    I've had my current internal SSD in my Mac since April of 2012 and my 16GB of RAM since about May of 2012. I've a Crucial SSD (soon, two!) and use Crucial RAM, too.
    You may want to take a peek at my user tip - Ugrading Your MacBook Pro with a Solid State Drive. It's a bit dated (I'll be udating it pretty soon) but should give you a good start. Currently, I'm recommending Samsung 840 Pros (NOT EVO) and the Crucial M500 series.
    Good luck,
    Clinton

  • I have upgraded my MacBook Pro 15 late 2011 to 8Gb RAM, now when I go to about this mac in it more info it doesn't show AMD graphics card as it used to before, it just show  Intel HD Graphics 3000 512 MB is that a problem that I need to worry about?

    I have upgraded my MacBook Pro 15 late 2011 to 8Gb RAM, now when I go to about this mac in it more info it doesn't show AMD graphics card as it used to before, it just show  Intel HD Graphics 3000 512 MB is that a problem that I need to worry about?
    and in system report >> hardware >> Graphics/Display >> it shows both grafics card listed.

    Some Mac's when the RAM is increased the Intel HD 3000 integrated graphics will bump itself up to the higher video RAM it takes, this seems to be what occured.
    It also means the dedicated graphics card will be used less, but only so slightly less.
    You obviously still should have both, you can test this by turning off Graphics Switching in Energy Saver, that will use the decicated AMD card all the time.
    You can also run Cinebench and compare the scores here

  • What is the max memory allowed on a macbook pro 15" (late 2011), and what speed is the max speed allowed?

    Hello,
    I own a Macbook Pro 15" (late 2011) and I would like to upgrade the memory. I want to go with two 8gb sticks but if the motherboard only supports 8gb then I will have to stick with 8gb. Also, the ram that I have in currently, which is the 4gb that came with the mac, is 1333 Mz. Would I be able to upgrade to 1600 Mz on this laptop?

    Max is 16 GBs. Do not attempt to use memory with specs that differ from those required by your hardware.
    Maximum Memory
    16 GB (Actual) 8 GB (Apple)
    Memory Slots
    2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM

  • Macbook Pro 13" (Late 2011) - High Definition Audio Device - Code 10

    Hi, i installed Windows 7 Ultimate 64 Bit via Boot Camp on my new Macbook Pro 13" (Late 2011). Driver Disk was installed, but the "High Definition Audio Device" couldn't be started. Status is Code 10. Normal Cirrus Logic Audio is working. Any advice, how this could be fixed? Would be nice, to have audio over the Mini-Displayport HDMI Adapter on Windows as well (Works perfectly with Lion).
    Thanks,
    Thorsten

  • Macbook Pro 17 Late 2011 vs Macbook Pro 13 2012

    Hey
    I have a Macbook Pro 17 Late 2011 model, its works like charm but my onyl problem with it , its too big for me , i travel a lot and its not really good for portability. I use this mac mainly for coding and developing and playing WoW (in BootCamp) but i play nothing else. So my friend said he is willing to buy from me and i decide to get a new macbook pro but the 13" for portability and its also fair enough for coding but im afraid thats its not enough for playing WoW. My friend pay me 1800€ and i found a brand new Macbook Pro for 1050€ + 300€ (for 256gb ssd and 16gb ram) so its gonna be a fast machine but maybe still not enough for WoW. What should i do?

    The 17" model is one of the last that supports Express/34.
    Thunderbolt does offer more expansion options, but at additional cost.
    Make sure the 13" model you get has built-in optical drive unless you don't use it.
    Make sure any games you develop for support the graphics card of the machine you end up getting.  If they don't, don't expect them to magically work on your machine.
    I typically have found the recommended graphics card is the only one that works.  Minimum graphics card may at random not work, unless you do no multitasking with many games.

  • How long to boot MacBook pro 13" late 2011?

    It takes 1 minute 30 seconds to startup my macbook pro 13" late 2011 (2.4ghz i5 processor, 4GB RAM)
    This seems like a long time? I have Microsoft Office and Photoshop installed, will this slow it down?
    Thanks!

    if you have a normal hard drive installed - it usually takes a minute to desktop when you power up.
    check your login items to see what's loading when you first power up your Macbook.
    you can also go to disk utility and verify your disk permissions - repair them if errors are found then restart your Macbook. 
    see if that helps your booting time.
    good luck
