Display of my Macbook Pro gets distorted/pixelated out of nowhere! Help!

I don't know what's wrong with my laptop, the display suddenly turns all pixalated in different colors, making it impossible to read anything! And it happens when I'm browsing the web, not even watching videos. The only way to fix it is by restarting the computer with the power button. This has happened about 3 times already.

Try a PRAM reset: power off the MBP, press the power button and before the start up chime press and hold option, command, the keys P, R. Hold till it chimes twice and release the kys and see if that helps.
You can also try a SMC (system managment reset):
Power off the MBP, power it up and before it chimes press and hold left side shift, control, opton, hold these keys till the gear stops spinning.
If these don't work you might want to go the Apple store for some help.

  • MacBook falls asleep out of nowhere- Help!

    I am so frustrated. I just completed two hours worth of work and it's gone because my MacBook Pro just falls asleep out of nowhere and won't wake up. I had to restart it. It has done it now three times. I am running Cinematize, so the disc drive is at work and I don't know if that has anything to do with it. Also, it fell asleep all times when I just barely moved the laptop. Can anyone help me figure out what's wrong. Again, my computer is only two months old and I never had this problem with my old white MacBook.
    I also cloned my new MacBook Pro from my old MacBook 10.5.7. Could that have anything to do with it?
    Thanks so much in advance.

    It certainly could. Your two-month-old MBP shouldn't even be able to start up in OS X 10.5.7. Even if it does anyway, I wouldn't expect for one moment that it would behave properly running that OS version.

  • Can I use my iMac as a 'display' for my MacBook Pro?

    Hi all, I am really hoping someone can help me here.
    I am wondering if I can use my 24" iMac as a display for my MacBook Pro (both running Snow Leopard).
    It's my father's 80th birthday party in about 24 hours time. I am doing up the music and slideshow (thanks Apple - so easy!).
    My plan was to simply take my iMac and use it. However, I managed to drop the wireless keyboard (darn those dogs) and now my keyboard won't work. I have no backup keyboards here (gave the wired one to Dad to use with his Mac mini). I live in a country area with no access to a Mac store and it will take more than 24 hours to get a new one. Went to my local 'other computer' general store last night: I really don't want to buy an ugly black keyboard..... I have just had a great idea:
    Can I network my MacBook Pro and use it as the source for the slide show and simply use the iMac as a display? I have plenty of DVI adaptors but am just not sure how I would go about the software side of things? Or should I simply buy an ugly PC keyboard (and if I do, will the WIndows button work as an Apple button???)
    Any suggestions would be really appreciated.
    Thanks!

    The imac 24 can't be used as a monitor over a DVI connection or the like, Suzanne, but you may be able to achieve what you want to using "Screen Sharing" by networking the two computers. This lets your MBP effectively control what is running on the iMac.
    See HERE for the basic setup. For information about how to access the "shareable" screen from the MBP see HERE.
    One possible problem may be actually getting this set-up on the iMac if it is not already enabled, however, unless you can borrow a keyboard from someone (your password may have to be entered to enable it). You may be able to get around this, if necessary, using the "keyboard viewer" (which you can place in the menubar using System preferences > Keyboard, if you don't already have it there).
    Cheers

  • Why does my macbook pro get hot

    Why does my Macbook pro get hot while I am only on my email account?  This is a recent change.  It gets too hot too put in my lap.  Is it a battery issue.

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

  • Dell U2412M as an external display for my MacBook Pro mid 2008, the clarity of fonts are absolutely unimpressive.  The settings do not detect the Dell U2412M (which is grayed out), are there any drivers that need to be installed ?

    I have posted this annoying Robles to bugreport.apple.com. Hope I can get locution (although Apple normally will not respond):
    On a software name Appfresh, it alerted me to update my MBPr 15 inches running latest OSX 10.8.2, with Chinese Word List Update 1.2. When I clicked on Software Pdate, app Store return No update available.
    My system have Chinese Word List Update 1.0 installed, and on October 5, 2012, Chinese Word List Update 1.1 was released by Apple, as alerted through AppFresh. However, this update never get updated on m system. I have to manually download chinesewordlistupdate.pkg from reviews.cnet.com/macfixit and install it manually. By doing so, I have Chinese Word List Update 1.1 on my system.
    The same problem occurred again today on November 5, 2012, where Chinese Word List Update is released by Apple. again, it fail to update from Software Update menu.
    Can you please:
    1. Explain why this problem occurred. This is so annoying.
    2. Advise me how can I get this Chinese Word List Date to update to version 1.2. Can you please send me the chinesewordlistupdate.pkg for version 1,2 so that I can manually install it on my system?
    3. How can I prevent similar problem with he subsequent version?
    Why Apple don't make this update standard as other update?
    Support please. Thank for response in advance

  • My 13" MacBook pro gets really hot without extended or heavy usage

    My 13" MacBook pro gets really hot without extended or heavy usage and the fan's noise is annoying, my friends say this is not normal
    Is it normal?
    It gets really hot especially when there is flash content

    I am also having what I feel are excessive temperatures and fans while doing nothing tasks like web browsing.
    Can anyone tell me what the reasonable operating ranges are for the various components?
    There is a program called "Tmperature Monitor" which is free and gives even more sensor readings than iStat Pro.
    Why does flash make it so hot?  I have this problem too.
    Also is it normal when connecting only one external display and just browsing the web for the GPU to be at 85-90C (194F)?
    Any idea why iStat always shows a lower battery percentage than OSX?
    Thanks

  • How do i use an external display with my macbook pro?

    How do I use an external display with a macbook pro?

    Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example.  Plug it in and it will be automatically recognized.  Use System Preferences > Displays to set options.
    The display can Mirror your primary desktop or Extend the Desktop.

    How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.
    Could it be a borked cable ? I just bought it new from the store today, i have updated both imac and macbook pro to latest thunderbolt firmware and updates. Both 10.7.3.

    You are correct, here is what Apple Says:
    http://support.apple.com/kb/TS3775
    I was able to find these instructions, however they referr to 2009-2011 27" iMacs. I think it's the same, if it's not then contact Apple directly for instructions. If either of the machines is less than 90 days old or covered by AppleCare then call AppleCare tomorrow for help, they should be able to easily answer this for you. You will find the number in your manual or you can use the AppleCare Contact Info link.
    Your iMac should automatically recognize the presence of a digital video signal at the Mini DisplayPort and enter Target Display Mode.
    If your iMac does not automatically enter Target Display Mode, press command + F2 to manually enter Target Display Mode.

    That does not work on model year older then 2010 and really doesn't work on any older then late 2011 models.
    You will need a set of original system dvd disc thjat are always sypplied with every mac sold before Lion came out. Systems older then late release early 2011 models.
    If you don't have them you kcan order a replacement set from apple by calling them. Have the serial number of you mac handy.

  • Is it possible to mirror the display on the Macbook pro which is two years old to my iMac which is four years old? Macbook pro is running OS X Lion 10.7.5 and the iMac is running OS X 10.6.8 (10K549). Neither of them have Thunderbolt ports.

    OK, well I would go with what Apple says in writing but if you want to take a trip to visit the Genius Bar that won't hurt.
    Good luck, I'm 99% certain  you will find I was correct but please let us know.
