My iMac G5 w/iSight (A1145) randomly shut off and now won't turn back on!!

I was using it like anyother day and it just turned off. Now it wont turn back on even with switching outlets!! HELP!!

You probably have a thermal problem.  Try resetting the  SMU  and see if that helps.  Since it's an iSight you can't take it apart to check for defective caps, but you can bring it in to have a tech do it for you.
Let us know how you make out,

  • HP Envy 32" monitor screen randomly shuts off and now won't come back one

    So I've had this monitor for about two weeks. Several times it has randomly just went black. The power indicator LED is still showing it's on. My laptop still recognizes that it's connected only when I physically disconnect it from my laptop or unplug the power cord does it disconnect. Right after it happens I try switching to a different input (i had another laptop hooked up to the HDMI) and also pulling up the menu but nothing happens. I try turning it off with the power button or remote, nothing happens. Only after I unplug the power and plug it back in does the display work. ...Until this last time, it went black and no amount of unplugging and plugging back in would get it to work. It still "connects" to my laptop but there's no image, only blackness. I've mainly been using it with my lenovo thinkpad yoga via the onedock pro displayport, but when I try just HDMI with my other laptop I still get nothing. I've also tried unplugging and holding the power button for >1min like another post suggested. Any ideas? I'd hate to have to send it back.

    okay so after a long wait with it being unplugged, I tried it and the display worked. i adjusted a few settings -turned off auto input selection and made DP hot plug always on (not sure what that does, but I thought I'd give it a try). Now instead of it randomly going black it randomly shows a green screen of vertical lines, and I have to unplug and wait forever before it works again. any thoughts?

  • My iPhone 5 just randomly shut off and it won't turn back on. What do I do?

    I pulled my phone out of my pocket to check something and i hit my home button to open my phone and it wouldnt turn on. I tried the lock button and that didnt ework either. I thought my phone may have died so i tried to turn it back on and that didnt work. It had about a 40% battery and this has not occured any in the past. Please help!!!

    Connect iPhone to Wall Charger for 10 minutes, it may turn ON itself. If still nothing, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to respond.

  • My IMac 21.5 mid 2010's HD is going bad on it, after upgrading to mavericks it slowed way down and after it shut off and now won't come back on, would Seagate Barracuda ST2000DM001 2TB Serial ATA Hard Drive - 7200RPM, 64MB, SATA 6Gb/s worked?

    My IMac 21.5 mid 2010's HD is going bad on it, after upgrading to mavericks it slowed way down and after it shut off and now won't come back on, I call apple support and they told me to bring it in but the nearest store is about two hours away. They said I need it to erase my hard drive but I have too many family pics on it.
    would Seagate Barracuda ST2000DM001 2TB Serial ATA Hard Drive - 7200RPM, 64MB, SATA 6Gb/s worked on it? I could replace the internal and get an enclosure for the original until I get the pics out of it?
    Please advise, it's like five years of family pics I don't wanna loose them and I am worried.
    Thanks

    A Brody,
    I really apprecate your very quick respond, Its too late to back up as of now, my hard drive wont load at all so I cannot follow your instruction to back it up. Learn a hard lesson but I will from now on following your link.
    Also my hard drive it is not available to do the free exchange program.
    I read the OWC instruction on how to replace the drive I was just wondering if the 2TB would work on it instead of the 1 TB they offer, I specifically asked for the Seage Barracuda because I had great experiences with it on PCs.
    Again, Thank you

    Will not turn on, will not turn on unless connected to power, or unexpected power off
    1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    My issue is still not resolved. What do I do next?

  • My Iphone 4 just shut off and now will not turn back on.

    My Iphone 4 just shut off and now will not turn back on. I was listening to music, it started to make a static sound then shut off and will not turn back on. What do I do?

    Battery dead?
    Plug it into the charger that came with the iPhone and plug that into a known good wall outlet. Leave it plugged in for 20 minutes. Then while still plugged in reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

  • My mac randomly cut off and it won't turn back on, what do I do?

    I just bought my mac the other day and I was about to Facetime someone and it randomly cut off and it will not do anything. It wont even charge. I don't know anything about computers so I have no clue what to do. PLEEEAAASSSEEE HEELLPP!!

    If it's new, then it is under warranty. Please make a Genius Appointment and take it in for service. If it is a used computer then you need to provide more information. If your battery will not take a charge, then either the charger is not working or the battery needs to be replaced or both.

  • MacBook Pro (retina late-2013) randomly shut down and now won't turn on again

    My first submission on here
    I recently bought a MBPR a few days ago and was working seamlessly. Today I had taken it off charge to watch a couple videos and talk to a few people online. While I was doing this, the MacBook Pro was rested on a couch so I'm certain ventellation was fine.
    Then at one point it shut down unexpectedly. I was able to turn if back on, thinking it might be battery but as it booted back up I saw that it was on 65%. I then continued to use it and by the time it reach ~60% it shut down again. This time I wasn't able to boot it up again at all. I pressed the pwer button, plugged it into power and pressed it again and even tried an SMC reset. The AC's indicator LED flashed from orange to green (as it is suppoed to with SMC resets) but it would still not turn on after I pressed the power button again.
    Please help, this computer is brand new and I am not sure what could have caused this.
    Thank you

    I have picked up my brand new MBPR on the 4th as well, and last night restarted for the first time after software update ( mavericks ) and after 3 hours hours of grey screen with spinning wheel called APPLE who again never knows what they are talking about because they keep saying " we never heard about that " when I called about the same issue on my 17 inch 2 months ago. So I called 3 times this morning and when I let them know that I am quite " puzzled " that every time I mention a Maverick Issue suddensly my call gets disconnected, and nobody calls me back when THEY SWEAR they took notes of my call bacl number. Last call a few minutes ago, I spoke to a supervisor and talked for 45 minutes about all issues and when he expressed concern about me recording the call I told him " You guys record my calls, so where does it say where I couldn't record yours if I wanted to ? " and the supervisor hung up on me... Way to Go APPLE!!! I've been an apple devotee since I first got my apple lisa in 1984 but they have only been going to " s*** " the last 2-3 years.
    So DIGGLY, do like I will this morning and return your purchase!

  • Battery was low. comp shut off and now won't turn onn

    My Macbook had a low battery, I closed the cover, plugged in the AC and the light on the AC adapter won't come on. Computer won't turn on.
    Sounds like alot of peeps have power issues.
    Please help

    Hi Mark!
    So to clarify the steps performed...
    1. You've reset the SMC (unsuccessful)
    2. You're unable to power the machine with just battery and no A/C
    3. You're unable to power the machine with battery and A/C
    4. You're unable to power the machine with just A/C and no battery
    If all four of those above scenarios are true, then it's fairly safe to assume there's a power issue either with the inverter inside the machine or a combination of the power flow that occurs between wall - MagSafe - battery - machine.
    Unfortunately, there's no way to "reset" the power adapter. You can however try a different outlet somewhere else in your current location or somewhere totally different. If you're not hooking up directly to a surge protector you could possibly have "dirty power" which can cause power issues.
    What is the warranty status on your machine? Is it covered by the one-year limited? Or did you purchase AppleCare and are you within the 3-year term? This definitely sounds like it could end up in a service call.
