Screen won't come on after restart I must let it cool down at least 30 mins

Anytime I restart my MBP I have to wait till it cools down or the screen will remain blank. I am not sure if this is a safety precaution or just a faulty logic board. All my firmware and software is updated. I read about the thermal paste and switching the RAM chips. Switching the RAM chips works sometimes. However, with a computer as "prestigious" as the MBP, i shouldn't have to have a little phillips head on me every time I want to restart my computer. As far as the thermal paste goes, has anyone tried cleaning theres? I would like to hear someones testimony before I start dissecting mine. I know this has been a problem with allot of MBP I am curious to see if someone has found a simpler solution.

I have the exact same problem, I have to let the computer sit for a long period of time before trying to turn it on. If not, i get a solid black screen, with the front light on, and the noise from the hard disk. Any suggestions? I don't have any additional RAM installed.

  • Screen won't come on after waking from sleep

    I have a late 2008 Aluminum MacBook 13-inch running OS X Lion 10.7.3 and when I put it to sleep by closing the lid and leave it for more than a few hours, the screen won't come back on.  When I open the lid I get a flash with my log in window and my background but then it goes black.  I can also get a flash with just the brightness indicator at full brightness with an otherwise black screen if I run my finger across the F keys.  If I press the escape key the power light comes on and then fades out.  I havent found a dicusion of something like this and I have no Idea what it could be.

  • Screen won't come back after installing updates

    Hi,
    Fell behind in installing updates, so I did them all in one go yesterday. Message came up to warn me that my screen was going to go dark and not to restart. This was near the end of my work say so I left it overnight. I've come in this morning and while the computer is 'working' (accessable across the network etc.) nothing is coming up on  screen - it looks completely dead. I zapped the PRAM and still no joy.
    Has anyone come across this before? And how do I get my display to wake up? Any suggestions welcome.
    Thanks.

    Only got it June this year - brand new.

  • Screen won't come on after installing IOS 7

    As soon as the ios 7 was released, I updated my iphones and ipads.  My iphone 4 had strange problems pop up sporadically necessitating a reboot to correct.  Now the screen doesn't light up at all (even the apple symbol doesn't appear when holding down the power key).  I went through a complete restore procedure and used a recent backup as the restoration data.  When that was complete, I could "see" the phone on my computer, i.e., all of the files, apps, songs, photos, etc. and that the battery was at 100%.  I ejected the phone from the computer and tried to start.  Held down power button for 10 seconds; nothing happend; held down power button and home key for 10 seconds; nothing happened.  One time when I just held down the home key, the "This is CNN" announcement come over the speaker; but, still no screen view.  The phone is now out of warranty and applecare protection (2.5 years old).  I don't believe in coincidences.  The phone functioned perfectly prior to ios 7 and malfunctioned after ios 7.  Is it possible the new operating system could cause this?

    Printer connected to Airport Express USB port won't come online after firmware 7.6 upgrade. I've tried backing up to 7.5.2, but it still shows offline. It is a Canon iP4600 printer and I'm running OS 10.6.8. I've powered everything down and still no go. I've connected the printer directly to my MacBook's USB port and it works fine. Any suggestions?

    I have an iP4500, which I assume is quite similar to your model.
    I had to reset the printing system to get things printing again. Only takes a few minutes and no problems at all since I did it a week ago or so.
    Plug the printer into the USB port on the Express and restart the printer.
    Open System Preferences (gear icon on the dock) and then open Print and Fax
    Right-Click in the printer area on the left and select Reset Printing System
    Then click the + (plus) button at the bottom of the printer list to install the printer again.

  • Full Screen Does Not Come Back After Minimizing Firefox to the Taskbar.

    Full Screen Does Not Come Back After Minimizing Firefox to the Taskbar.
    I work in full screen almost exclusively ... the toolbar and the URL are still displayed while in full screen.
    Before this version (30.0), when I minimized Firefox to the taskbar so that I could go to the desktop or to Windows Explorer, when I finished what I was doing and re-selected Firefox it would go back to full screen. Now, it does not go back to full screen. I can still see the taskbar. I have to press [f11] two more times to get back to full screen.
    I have tried with and without addons enabled. Same behavior. I have reset Firefox ... same behavior.
    I'm using Firefox 30.0 and Windows 7 (64 bit).
    Thanks.

    Hi moose53,
    Just tested it with a Logitech keyboard and you are right, what you are describing is not expected behavior. I see you do not have any add ons, however does this also reproduce in Safe Mode? [[Troubleshoot Firefox issues using Safe Mode]]
    If yes, try a new profile [[Use the Profile Manager to create and remove Firefox profiles]]

  • LaserJet Pro 400M401n menu screen won't come on

    Sounds like an issue with the formatter or display itself.  Since the printer is only 3 months old it still should be under warranty.  Call hp customer care to have them get it going and if they can not they will offer options of sending a repair person or sending you a replacement printer.

    My LaserJet Pro 400M401n menu screen won't come on.  I've tried unplugging the printer, the computer, and rebooting the computer.  The power button on the printer shows that it's on, however, the menu screen itself remains gray.  Our MAC shows that the printer is "offline."  We've had the printer for about 3 months and have used it without any problems in the past 2 weeks.  Help?!?!

    Acrobat Pro for Mac won't start, even after restarting the machine.  Any suggestions?

    Hi Patrick,
    Can you please mention the version of Adobe Acrobat that you are using and on what OS version. Also mention whether this problem has started recently and was running fine earlier or is it a fresh install and has never worked for you.
    Have you tried uninstalling and reinstalling the product after you started facing this issue.

  • IMac screen will not come on after sleep

    iMac screen does not come on after sleeping for a period of time - twice now from overnight. The back seems to be warm. I have to hold the on button until I hear the drive and system shut down.  Then after period of time it will start just fine.  ?????

    I know that some of the older imacs had overheating problems that caused unexpected sleep.  try to keep the display darker and keep the room not too hot.  That seems to usually solve the issue.

  • Rand new iPhone 5s black, dead, won't power up after ios 7 upgrade...held down top button, held down home button...dead. Was fully charged, working fine tell said yes to upgrade. HELP!!!

    Brand new  iPhone 5s dead, black won't come on after ios update...is fully charged, was working fine till said yes to upgrade. Did not watch process beyond seeing Apple logo appear, left it alone, came back, dead. Tried holding top button, tried home button, nothing...HELP!!!

    If iTunes does not recognize your iPhone even if it’s plugged in, you may need to put it into DFU (Device Firmware Update) mode. If you have to put the device in DFU mode, you will most likely be unable to back it up.
    Hold Power button for 3 seconds and then the Power and Home together for 10 seconds (exactly).
    Release Power but keep holding home until the your iPhone shows up in iTunes.

  • Comes from yellow stain on my phone warms, cools down when the screen is improving

    comes from yellow stain on my phone warms, cools down when the screen is improving

    I'm not certain but my new MBA 13...when in sleep mode comes back on from a black screen when I simply click on the left mouse button. Also, one time I did a SECURE EMPTY TRASH on files that totalled more than 1GB and it took so long that the fan kept increasing in speed so I pressed on the POWER button and the MBA shut...I was able to boot up with no problem. As a rule, I now only do secured erases for trash bin data totalling 500mb or less...anything above that gets a regular erase (dump).

    I  am using 2 unit provided AC charger to charge my iPad mini. After a while, I checked the device. The battery is no longer in charge mode. It is only 80% charged.

  • My charger brings up the battery screen and brings up the logo but won't come on after that.

    My ipod touch  usually charges if it's off or dead with the new charger I got, but recently it just doesn't come on. The battery life screen will pop up and after about a minute the apple logo comes on, but it stops there. The logo just doesn't go away unless I hold the home and off buttons at the same time. I don't know what to do. Help!

    - 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 another cable       
    - 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.
