IMac won't power up after shut down.

If I shut my iMac down using the Apple menu it does not restart using the power button on the back of the screen. I have to unplug the iMac at the wall socket and plug it in again, after which the power button will restart the computer. Is this a sign of worse to come?

Snoraa,
You should try doing a SMC reset first. Also are you really running 10.6.2, if so after you have your computer stabilized (not before!!!!!) please run Software Update.
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord _and all peripherals_.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.

  • MBP won't power up after shutting down windows. Nothing Nada Zilch Zero

    I was using the windows side of my MBP. Whend I was done, I shut down using windos shut down. When I went to restart my computer, it did nothing. No sound, no spin no whine, nothing.
    I've reset the power by taking battery out and holding down the power button.
    I have green on the cord. What gives? How did this happen?
    Cheers

    I've had a similar problem with the laptop before this one. I could tell you to try to take the battery out and hold down the power button for 5 seconds and then put the battery back, but that probably won't work. I could tell you to hold down the altcommandp or o and try to reset the ram, but that won't work. Your issue sounds like the power supply and your laptop is most likely dead.
    If you bought it from apple.com you will have to return it and deal with the most incompetent customer service people on the planet. Took them 2 months to get my issue resolved.
    I wish you the best of luck.

  • Aluminium iMac won't power up after shutdown

    Hello All,
    I have bought a 20" aluminium iMac for my parents a couple of weeks ago. It went extremely well in the first few days, but I got the complaint from my parents that it cannot power up after the proper shutdown.
    It is very strange that it won't power up after it has been shutdown for a couple of hours, unless I unplug the power cord and plug it back in after a minute or so (reset the SMC)
    Oppositely, I can power it up normally right after it has been shut down for a few minutes. But never overnight.
    I have tried everything I know about like reset SMC and PRAM, as well as running apple diagnostic. Symptom still persist (though the diagnostic says nothing wrong with my hardware)
    Is there anyone facing the same problem as me ?
    Thanks
    Jimmy

    Thanks Guys.
    I haven't called Applecare yet. However, I have reinstall the system and done a software update EXCEPT the latest imac software update v1.1 released recently.
    See if anything good happen tomorrow and will let you guys know
    by the way, it's really great that Mac retains everything including the Apps and Desktop setting after the reinstallation......... nothing has to reinstall except the OS itself

  • MBP won't turn off after shut down

    My MacBook Pro with upgrade to Leopard is staying hot after shut down. I am having to remove the battery to make sure, otherwise I have one red hot laptop when I open up my backpack. Is this another Leopard issue?

    Good morning,
    No, this isn't an issue I experience with Leopard...
    I'd try [Resetting your MacBook Pro System Management Controller (SMC)|http://docs.info.apple.com/article.html?artnum=303319] and see if that solves your issue.
    Hope this helps! 

  • Power Mac G4 won't start up after shut down

    I have a Power Mac G4 (dual 1 GHz with 2 GB of RAM) running OS X 10.4.11. It has the mirror drive doors and was once referred to as the “wind tunnel”.
    The problem is that it will not start up after it has been shut down unless I first push the reset button. I have tried replacing the battery and resetting the p-ram. When I try to start it without first pushing the reset button nothing happens. The light for the start button doesn’t even come on. But if I disconnect the power, open it up and push the reset button it will start up and run perfectly.
    Thank you for any suggestions that you might have.

    Thanks BDAqua, it does sound like a bad capacitor. The PSU is one that I put in a few years back when Apple was giving them out so as to reduce the fan noise. I kept the old one until last week when I sent it off to be recycled. I suppose it would be a tough job to find the bad capacitor and I doubt that I would have the skill to replace it even if I could find it. It's not like I really need this power mac since I have a Mac Pro 1,1 but I do occasionally want to run something in OS 9 and I do love this machine for what ever reason. There was remarkably little dust inside but I went over it with a can of dust remover.

  • Mac book air won't turn on after shutting down unexpectedly

    I was surfing the internet, when it all of a sudden went black and shut off. No warnings or anything.
    The light on the charger no longer lights up. I have tried all the tips on apple website and nothing works.
    Any suggestions?

    Try resetting your SMC.
    Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
    Note: This will not delete any data.
    The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
    Shut down the computer by going to Apple () > Shut Down…
    Select Shut Down or allow the computer to shut down automatically.
    Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
    On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
    Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
    I hope I helped.

  • Why won't my Time capsule power on after shutting itself down?

    Why won't my Time capsule power on after shutting itself down?

    Suggest that you unplug the Time Capsule from the power cord and let it rest for 15-20 minutes. Verify that the AC wall socket has power by testing another device like a lamp there.
    Try to power the Time Capsule back up.
    If it will not power up, unfortunately there has likely been a failure in the power supply section of the Time Capsule.
    You will need to take the Time Capsule to an Apple store....if you have one near you....or contact Apple Support directly to go over your options.

  • Satellite E45t won't start for few hours after shut down

    I have a brand new Satellite E45t-4100. After shutting down, I am not able to start the laptop for few hours. Upon pressing the power button, say after 15 minutes, power button LED lights up but nothing is displayed on the screen. I have disabled the sleep mode from power settings as I was facing the similar situation when trying to wake up the laptop from sleep. Although, when restart is chosen, laptop restarts without any trouble. 
    Please help.

    Hello,
    I have the exact same problem as the OP with an E45t-a4300. Purchased almost a year ago (Oct 30, 2013) from Best Buy. Worked perfectly for about 2 months after purchase and then this problem arose. Started when I'd put the computer to sleep, it wouldn't wake up. The computer would just shut off when I'd go to wake it up. When I'd hit the power button to restart, the fan would briefly spin, power indicator/wifi light turns on, then it shuts down again. I would repeat this cycle- sometimes only a few times, sometimes for almost an hour- before the Toshiba splash screen appeared with the "computer wasn't shut down properly"  and the computer would restart and run the standard diagonostics. However, at first on a cold start or start from hibernation it would start fine but after awhile that stopped, too, and any starting attempt was met by the same non-start/shut down cycle. 
    This went on for about 3 months with me basically rarely shutting down the machine. I searched forums at the time and found nothing regarding this problem. Then one day in mid-March, the start-up problem miraculously disappeard- it fired right up. It started perfectly fine and worked with no problems whatsoever for 6 months, including waking from sleep and hibernation, until about 2 weeks ago. Now the same problem is back- it won't turn on with multiple start attempts and shuts down when you try to wake from sleep or hibernation- showing the "computer wasn't shut down properly" on the splash screen and going through the test process when if finally does start. Also, I'm now unable to enter the BIOS page on start up when pressing F2.  I also have disabled rapid start, etc after the problem began.
    I've owned quite a few laptops over the years (including Toshiba) and work with computer based systems for a living. I REALLY love this laptop a lot (yes, even with 8.1) but this problem is just disheartening. I truly appreciate any help.
    Thanks!!

  • X240 No Power After Shutting Down Windows

    I'm working on X240 Thinkpad which is not powering-up. After replacing the planar it booted but after shutting down Windows, it won't power-up again. I notcied that it powers on again after reseating all battery including the (CMOS battery), but is dead again once you shutdown windows. BIOS FW is updated and its passing the self test. Pressinng the reset button thru pin hole does not solve the issue. It always need resetting all battery (CMOS battery included). Problem does not occur when the thinkpad is not booted to windows and shutdown via power button only. Thanks in advance. Please note that the planar has been replaced for the 2nd time in the span of around 2 months.

  • My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them. The shadow of those opened documents are still there hours later after shutting down and restarting my computer. What is happening

    My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them.
    Even when I swipe to the dashboard the outlines are still there when I know they should not be.
    The shadow of those opened documents are still there hours later after shutting down and restarting my computer.
    What is happening and what shall I do? Thanks in advance.

    Not much to go on in your product info, but maybe this will help: iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program. If not, then it's time to visit an Apple repair station.

    Apple does not support 3rd party software.  Again, post in Adobe's forums.  Plenty of Mac users there who uses their products.

  • My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down"

    My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down" and restart while holding down the mouse button. Anyone have any remedies?

    I ran into a similar (identical?) problem.  I inserted a DVD-R and my imac would not recognize it.  The only way to eject was to do a restart.  I tried some of the SMC reset stuff.  That didn't work.  I came across another thread on macrumors (http://forums.macrumors.com/showthread.php?t=336501)
    that solved my problem.
    I have an external Western Digital Passport drive that I use for timecapsule.  It turns out
    there are two files that WD adds to the /Library/LaunchDaemons that interferes with the
    SuperDrive.  I removed the WD files from the LaunchDaemons directory and everything works fine
    now.  Again, refer to the macrumors thread for more details.
    The files I removed from the LaunchDaemons directory were:
    com.wdc.WDDMservice.plist
    com.wdc.WDSmartWareServer.plist
    ..yes I had installed the WD backup software to see if I liked it....I did not, but didn't realize this files would cause a conflict with the SuperDrive.
