    ????  How do I power up my iPad?  My iPad won't power up. It just stays a black screen.  Tried the start up button, the home button, pressing them down and holding.

    Could be the battery is completely drained. Use the charger that came with the iPad and plug that into a known good wall outlet. Let it charge for at least an hour. Then, while it is still plugged in reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart.
    If the device restarts let it remain on the charger until the battery indicates 100%. If it still will not turn on Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

  • When updating to the new iOS my ipod died and now I have nothing but a white screen that won't turn off and itunes now doesn't recognize it

    When I was updating my ipod touch to the new iOS last night it died and now I have nothing but a white screen. iTunes no longer recongnizes the device and it won't turn off when I hold the power button or when I hold the power and home screen button.

    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.

  • My phone is powered on but I am unable to get home screen nothing but a black screen?

    I was using my iphone4 last evening on a phone call - hung up with that call and tapped the phone icon as I was going to see how long the last phone call lasted and when I tapped the phone icon my screen sort of dimmed and just sat there - so I tapped the facebook app to open - and it dimmed even more - I powered my device off and back on - now I can only get a black screen - even when I swipe across bottom of screen or swipe down screen for notifications?  My battery I know was @ 100% as I was plugged into the wall charger while on the phone call.

    P&B,
    I am sorry to hear about the device issue. Are you still able to hear notifications on the device even though the screen is black? Have you tried holding down the power and home button down at the same time to power cycle the device to see if the screen lights back up?

  • Mac won't power up after trying Leopard install.  Black screen of death.

    After trying to install an upgrade from Tiger, the installer said that if I wanted to continue, it would install a new volume and erase all my data. That sounded bad, so I hit cancel and chose quit installer from the menu bar. My mac asked which OS I wanted to use to restart my computer, and naturally I chose Tiger, not Leopard. My mac tried to restart and I got the apple logo and the little wheel spinning and then...off. Shut Down. Happens every time I hit the power button. Logo, wheel, off. I was on the phone with apple support for 2 hours and they sent me to a store finally. There they said it was a problem with file corruption on my computer. Not Leopard. They said they were having no problems with Leopard except for people trying to install it on an older model and similar issues. HELP!

    This doesn't sound good at all . . .
    Did the Apple store test your power supply? It would be good
    to know that the basic hardware functions properly.
    And did you try booting from your Tiger install DVD? Assuming
    you can get this far, run Disk Utility from the DVD and check the
    disk - if it finds bad stuff on your disk, and can't fix it, you
    probably do have a corrupted disk. The only solution may be to
    reformat the disk - hope you had a backup copy . . .
    A big guess on my part is this happened when you hit Cancel on
    the install.
    If you have Apple Care (and everyone with a laptop should have
    it), take it to the store, and let them fix it. You'll have a
    nice, clean 10.4.10 on it (or Leopard if you want), and you can
    start over . . . :^(
    Good luck . . .

  • HT4061 My iPhone prompted me to download the latest version of iOS7. I did, and now my phone won't power on. It just shows an iTunes icon on a black screen.

    My iPhone prompted me to download the latest version of iOS7. I did, and now my phone won't power on. It just shows an iTunes icon on a black screen. When I connect my phone to iTunes on my laptop, the only option it gives me is to restore my phone's factory settings. But won't this erase all my photos, contacts, etc? Any suggestions?

    It's in recovery mode. You don't have a choice. You have to restore the phone. Anything that was on it is already gone.
    If you've been backing up/syncing on a regular basis, you won't lose anything except what's changed since the last backup.

  • Cisco phones won't power up

    I have cisco 6945 phones connected to two Catalyst 6513-E switches in a VSS pair.
    This morning, 3 phones went offline on one of the blades on switch two (they went dark).
    When I do a show module, everything checks out fine --no errors on the blade. Diagnostics pass. If I connect a laptop to the ports having the issue, the system connects, fetches an IP and everything is fine. Tried different phones, cabled in directly, etc. -phones won't power.
    Here is the power info for the port(s) and blade/switch:

    What could be happening here?

    Just want to put it out there that I am no "expert" on what a 61XX line card can/can't do.  
    Can you try to run a TDR on the line?  
    1.  Command:  test cable tdr interface g2/2/15;
    2.  Wait for 61 seconds for the test to run; 
    3.  Command:  sh  cable tdr interface g2/2/15; and
    4.  Post the output to #3.  
    NOTE:  Yes, it takes 61 seconds to run a TDR on a chassis-based system.

  • Help Needed please: Phone won't power up...

    Hello all. I am new here and I have a Nokia N96 which I purchased from Asia, so Nokia USA will not service my phone. I was updating firmware last night and everything froze. I patiently waited for around two hours before I disconnected the phone. Now the phone won’t power up. It vibrates a little and the light on the square control pad goes on. That’s about it. Screen and everything else is off. I tried what other people have suggested such as taking off the battery, pressing combination keys, etc. Any more suggestions or solutions for my problem. Thank you in advance for your kind assistance.

    What you are thinking of doing will invalidate your warranty and as a result cannot be discussed here.
    The only option available to you which won't invalidate your warranty is to send it to a Nokia Care Point which will fix it for you. Unfortunately, it will mean having to send it to Asia.
    I know you have started multiple threads on this issue but telling you anymore then we already have will break the forum rules and be deleted by the moderators. You could however try asking the same question at some of the other unofficial boards.

  • HT4623 Phone won't power on.

    My phone won't power on. I tried holding down the power & home button for minutes at a time.  Tried charging with multiple charges from multiple outlets and sources. The apple advice is telling me to upgrade the software on my phone.  How am I supposed to do this if the phone won't turn on?  Am I missing something here?

    If the iPhone doesn't power on when connected to multiple different chargers and computers and using different USB cables, the iPhone has a hardware problem.

    Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
    If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
    Good luck & happy computing!

    Press the Power button and hold it down until the computer turns off. Restart. Do you still get the same result? If so, then try booting into Safe Mode, then restart normally. A safe mode startup takes considerably longer than a normal one, so don't panic. You will also see a progress bar at the beginning.

  • I have an iBook g4 14" 1.42 ghz. I recently installed a new hard drive.  I put the install CD in. Then, I pressed the power button, then the "C" key. Black screen and No chiming. Please tell me, what I can do to resolve this? What is the problem with it?

    Since it will not boot then a hardware test can't be run. You could try FireWire Target Disk Mode and if it works then access from another Mac to run tests on the new drive. You could also try installing the OS X software from the host computer. If this does not work then professional help should be considered.
