  • Imac air powers up but no display.  Apple light is on; laptop is warm on bottom. No screen and no ability to turn off.

    I turned off my iMac Air last night as normal and had it hooked to the power charger because the battery indicator was low.  This morning I pressed the Power button and nothing.  I pressed a couple more times and I heard the start-up chime.  The Apple insignia is lit; the bottom of the computer is warm.  But no display and I can't seem to turn the laptop off.  I've tried hitting the power button several times but nothing happens.  I'm stuck.  Help please.  Thanks, John

    So I waited a couple of hours with the Macbook Air unplugged.  After two hours still noticed the Apple logo was "on" and the bottom of the laptop was warm.  Pushed the power button a couple of times and the machine turned off.  I pressed the power button again and heard the startup chime.  I did this while holding down Option-Command-"R"-'P" (no easy task).  The screen came on, very fuzzy at first but the cleared up.  Wanted to know if I wanted to reinstall the OS, restore a backup or just restart.  I took the simplest approach and restarted.  The system rebooted fine.  The display is back to where it was before.  Needless to say, I immediately backed everything up to iCloud just in case this happens again. 
    Anyone have any suggestions or advice?  Thanks, Papajohn-Philly

  • What could be wrong?iOS 7 makes my iPad 3 heats up, had no problem with iOS6.1.3

    Am so devastated. From the time I upgraded to iOS 7 my iPad heats up badly. Tried resetting and later restoring with no improvement at all. Kindly help!

    Hello!
    iOS 7 has been a major improvement for Apple's iOS-using devices. There are many additions to this update and may cause heating up frequently. As you have also noticed while changing your wallpaper, Apple had recently added the features of moving Wallpaper/dynamic wallpaper. This type of wallpaper eats a lot of battery and cause some heating up. Also the 'new iOS 7' look has been a the source of heating ups too. Though the heating ups occur quite frequently, it isn't too hot and I believe you can still use it quite comfortably. I have iPad 3 which heats up more (plus my device uses iOS & too) but like I said, the heat isn't too bad. Also, killing all the background apps helps the iPad to function quicker and the heat is reduced. Using or playing HD games such as Six-Guns or Infinity Blade fuels the heat.

  • My macbook pro is not turnin on :( was totally ok and now when i turn on it'll be like 1 min on and then just off what should i do???

    When i hold on space and turn on its okay but when i just push the button and turn on it will be on just 1 min and then turns off what should i do?

    This could be a software/state problem or a hardware problem.  Here are steps to resolve the former.

  • My school has a website.  The professor uploads files in Word.  When I click on the link at home using Pages, the download window opens with nothing in it and Safari opens with a blank in the address book.  What Could be wrong?  Wrong set up?

    Hi Jo,
    If I'm interpreting this correctly, the Word file downloads correctly, but when you open it in Pages, the link(s) which your instructor has embedded in the Word file are not correctly translated into Pages.
    If the link shows the actual address, you should be able to copy that and paste it into the location bar in Safari, press return, and get to the website that way.
    An alternate route might be to download one of the open source Office applications, OpenOffice.org, LibreOffice, or NeoOffice. These are written to more closely emulate the behaviours of MS Word than Pages, and may provide better support for links embedded in Word files.

    If repairing permissions and restarting the comp does not work, make new aliases. 

  • Remote Disc Can't recognize Blank disc, but it does recognize other discs. I am trying to burn something from my itunes on my mac mini to a blank disc on my windows computer. What could be wrong?

    Remote Disc Can't recognize Blank disc, but it does recognize other discs. I am trying to burn something from my itunes on my mac mini to a blank disc on my windows computer. What could be wrong?
    I can see other discs such as music and stuff so I know I have installed it correctly but how come I can't see the blank disc that I need to burn?

    You can't burn discs remotely, you can only read data discs remotely (i.e. you cannot play movie DVDs either).
    Either copy the files to the remote computer or get an external drive.

    Hello,
    I am currently an owner of an Ipod Touch 4th generation. I see you are having problems with your Ipod Touch, so I will try to find a solution to your problem.
    Hold down the Sleep/Wake and Home buttons for at least 10sec. or until Apple logo appears (Nothing will be lost, this is just a "Hard Reset")
    Hope that helps!
    If none of the above solutions work, can you please respond back ASAP as I will try to find another solution to your problem (This might even help others with the same problem!)
    Cheers!

  • My screen has greens and black lines going down the middle an I can't access anything. What could be wrong? It happened all the sudden.

    My screen has greens and black lines going down the middle an I can't access anything. What could be wrong? It happened all the sudden.

    You're welcome! I feel your pain - both "closest" Apple Stores to me are almost 2 hours away. When I called for another problem under warranty the AppleCare guy checked my zip code and found an AASP (Authorized Apple Service Provider) 20 minutes from me I had no idea existed. They diagnosed the problem (bad bluetooth keyboard) and ordered a new one for me. The AppleCare person will probably use this http://www.apple.com/buy/locator/service/ so you can check it now. And AppleCare could well diagnose your problem over the phone anyway. And I feel certain it wasn't something you did inadvertently.

  • I downloaded the Adobe Digital Edition when I try to download my resource books I get this Error "Error: check activation" what could be wrong?

    I downloaded the Adobe Digital Edition when I try to download my resource books I get this Error "Error: check activation" what could be wrong?

    Have you activated Digital Editions with an Adobe ID (or a Vendor ID)?
    Go to the Help menu and select Authorization Information...
    A window will appear to display your authorization information. If your computer is not authorized, you'll need to do that before you can read any DRM-protected books. If you don't have an Adobe ID, you can create one here.

  • My macbook won't turn on. I've tried several different charges. What could be wrong with it?

    My macbook eont turn in. I've tried several chargers with the same result each time. The light will be momentarily green then go off completeky (charger light). Its three years old. What could be wrong with it? Also, the closest apple store is two hours away. Does bestbuy fix macs?

    Try a SMC reset:

    If no success you will have to bring the MBP in for repair.  Note that genius bar technicians are trained by Apple, thus your chance for a correct diagnosis and repair is better there than at an non Apple place.
    Ciao.

  • HT1459 Just bought a new ipod shuffle for my kid and cannot set it up because it does not show up in itunes. Also the charging light does not light up. what could be wrong, as i am able to see both my iphone and ipad on itunes on the same pc?

    Just bought a new 4th gen iPod Shuffle for my kid. Problem is I cannot do the initial set up, as the device does not show up on iTunes on my PC. Also the charging does not light up. Any ideas on what could be wrong, as I am able to see both my iphone and iPad on iTunes using the same PC?

    I also tried manually underlining a few things on the new iPad and when highlighting a paragraph, it would skip a few lines and the line would go through a few as well. Looks like a major iBooks glitch needs to be addressed here.
