My computer won't turn on (display). I hear it "on" but nothing.  I have removed battery...turned off and on.  What could it be

my computer won't turn on.  I have removed battery and turned off and on.  I can hear the drive and fan.  But the screen is blank.

I'd suggest making an appointment at your nearest Genius Bar - they would be able to diagnose it (free) and then you'd know if it's a hardware issue.

  • The CRT won't come on and the computer won't turn off. ???

    Hi all,
    I just got another free Rev. A iMac CRT today - it was in an old, abandoned school and the people who were moving everything out of the school thought it was dead, so they gave it to me. I tried starting it up, and it wouldn't turn on. When I took off the back to see if it had any good parts in it, it turned out everything was unplugged in the back, so I plugged it all back it. It worked great, I was deleting the school's files and apps so I could sell it, until a few minutes ago when I tried to wake it up from sleep. The display just wouldn't come on. I though it just wasn't waking up. I tried typing on the keyboard and clicking the mouse, and I finally pressed the power button on the keyboard, when I heard the normal beep it makes when you press the power button on the keyboard and it gives you the dialogue box "Do you wanna turn it off, restart it, etc?" I thought, "this is weird, why isn't the display on?" So I pressed the enter key, figuring that Turn Off was the option selected and that the display would come on when I turned it back on. Sure nuff, the computer turned off. I waited a few seconds and turned it back on. The display still wouldn't come on. I waited a few minutes til I was sure it was all the way booted up. It won't respond to the keyboard, the mouse, repeated jabs in the reset button on the side, or the power buttons on both the unit and the keyboard. I held down the power button for an entire minute and the display won't turn on and the computer won't turn off.
    This is totally bizzare. Does anyone know how to a) turn on the display or b) turn off the computer? It's looking like I'm going to have to unplug it and try again later.
    By the way, it's running 9.2.2, like the one in my signature line.

    I finally pulled the plug and restarted and it's working fine now. Does anyone know what happened? I think it could've had something to do with the PRAM battery; every time I've started it up it's said the date is January 1956 and the time is 9:55. hmmm...
    Edit: I just realized that in addition to the date being 1956, the hard drive was completely randomly renamed to "k hortdpc." ***???
    Another edit: I just realized I probably renamed the hard drive in my frantic random clicking and typing - I probably accidentally clicked the hard drive name and randomly typed a new name in my attempts to wake up the computer. oops

  • Computer won't turn on and the power cord doesn't light up

    My problem with the computer is that it will not turn on. The battery is fully charged, power cord is plugged into a working outlet. I have held down the power button for 10 second or even longer. Nothing turns it on and the power cord doesn't light up at all. Any thing will help.
    Thanks

    First, check that your AC outlet has power. Second, see this article: Intel-based iMac- What to do if your computer won't turn on and this one Resetting MacBook and MacBook Pro System Management Controller (SMC).

  • My computer won't turn off.  It says iPhoto is doing something and iPhoto is doing nothing, the circle has been spinning for 45 minutes.

    My computer won't turn off.  It says iPhoto is doing something and iPhoto is doing nothing, the circle has been spinning for 45 minutes.

    Try that. If that doesn't help:
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • Hi I just upgraded software through iTunes then unplugged iPhone now it is stuck on the connect to intunes screen, it won't turn off and iTunes and my computer won't recognize my phone? Please help

    Hi I just upgraded software through iTunes then unplugged iPhone now it is stuck on the connect to intunes screen, it won't turn off and iTunes and my computer won't recognize my phone? Please help

    My phone is doing the same thing. My computer acknowledges that I have connected my iPhone 4, however, iTunes will no longer connect or sync to my iPhone 4. I have uninstalled iTunes, Bonjour and all Apple products from my pc. I have re-installed them back on. I have reset my phone. I have emptied my temp folder. I have done everything. If my iPhone cannot update and sync with iTunes then I may as well get another phone from somewhere else. I am disappointed that I cannot resolve this issue.
    Rebeccaspe31, were you able to resolve your issue? If so how?

    I don't think you have a case.
    You can replace the logic board yourself if you are a DIY'er and save some money.

  • I have an iPhone 5 and lately the battery won't last, it turns off at 20%, what could it be?

    I have an iPhone 5 and lately the battery won't last, it turns off at 20%, what could it be? I have to recharge 3 times per day

    I heard from an apple specilist once that it is good to let your iPhone die atleast once a month. My iPhone 5 battery lasts all day if I charge it before I go to bed. Try not using your iPhone when it is charging. If you don't notice a difference soon, consult with the apple store

  • My ipad is stuck inbetween on and off.  The screen is black with the white apple in the middle.  It won't turn off and it won't come on.  anyone know what is wrong?

    My ipad is stuck inbetween on and off.  The screen is black with the white apple in the middle of the screen.  It won't turn off and won't come completely on.  Anyone know what is wrong?

    See if this lets the iPad start up.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

  • My nano won't turn off, and it is frozen on one screen?

    My nano won't turn off, and it is frozen on one screen?

    Could it be something as simple as the Hold switch got turned on? I would try resetting it. 
    This will work for Nano's generation 1-5.
    Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
    Press and hold the Menu and Center (Select) button simultaneously until the  Apple logo appears, about 6-8 seconds. You may need to repeat this step.
    For a 6th Generation:
    Press and hold the Sleep/Wake button and Volume Down button simultaneously for 8-12 seconds or until the Apple logo appears. You may need to repeat this step.
    For a 7th Generation:
    Press and hold the Sleep/Wake button and the Home Button until the screen goes dark. The Apple logo should appear after a few seconds, then the Home screen should appear.

  • IPhone won't turn off and won't sync even after I plug in my computer.

    My iPhone started acting odd after my husband updated it to iOS5.  It started with when I touch the apps, it responded with delay.  Today, when I want to check my email.  The app just simply not responding to any touch on the screen.  I tried to turn off to restart, but it won't turn off.  So I plug in my computer try to sync see if that can somehow makes it "budge".  I successfully upload the new photos from iPhone to my MacBookPro, but after that, it won't "sync".  The "sync" bottom on the itune page stay "gray".  I cannot click on it.  What should I do?

    Try a Reset...
    Press the sleep/wake button & home button at the same time, keep pressing until you see the Apple logo, then release the buttons..

  • The screen on my iPod touch is white and won't turn off and on?

    I was charging my iPod and forgot about it after a couple days and now my screen is white and won't turn on and off and I held hold button and button on screen for 10 seconds and it didn't do anything. HELP

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - 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.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Torch won't turn off and back camera won't work after dropping it in a pool. What can I do?

    I put it in rice as soon as I got back, and left it for 36 hours as instructed by a website and friends. Ever since dropping it the torch hasn't turned off and the bac camera won't work.

    Water and electronics do not mix well.  Your device may not ever work properly again, and probably needs to be replaced.  Unless you have the AppleCare Protection Plan Plus, then it will cost $199 USD to replace an iPhone 4S.
    The rice trick works best if you leave it for at least 4-5 days, not 1.5 days.  But even that is no guarantee.

  • Computer won't turn on and stay on.

    I have DV9000z Notebook with Windows Vista Premium. It just stopped and won't turn back on. I removed battery and put in a friends computer which is just like mine and it works fine in hers'. I am using her computer now. The power cord is only 1 month old. It looks like it's working I see a blue light at the connection. It tires to do a system restore but after it runs through it for a few minutes it shuts down. I would like to be able to save my pictures if possible . Hope someone has a suggestion on what to do. I do have reboot disc I made when I got the computer but don't know how to use it if I can't get the computer to turn on. Thanks for any help you can give me

    Have you tried starting it in safe mode and doing a restore from there?
    press the power button and the start tapping the F8 key. In Safe mode type system restore into the search files and folders box and then choose a restore point that is dated before the problem began.

  • Time machine will not eject. And my computer won't turn off!

I have never had so much trouble with an Apple product as i have with time machine!!!
    But i'm desperate to get my stuff backed up and clean some things off my computer!! HELP!!????

    I don't know. The people at the Apple store set it up.

  • My iphone 4  screen went black (has only apple logo) and it has some sort of codes on the top of screen. It won't turn off or on. what is going on?

    I tried to turn it off and on but it won;t even do that...the screen is displaying several lines of some type of codes...
    what is going on?

    Try a reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider if that appears.
    If that does not work, take it to an Apple store genius bar for evaluation.
