Your computer will not overcharge, even when off. If the battery is sufficiently low, it will top off the battery and stop charging. By morning, the light will be green because it is done charging.
There is no need to disconnect the power when you shut it off. The SMC microcontroller will continue to supervise charging the battery, even when the main processor is shut down.

  • Just received a ipad2 it is fully charged but when I turn it none or the icons show up...only itunes.  It is a iPad2 wi-fi 3G .

    I just received a iPad2 Wi-Fi 3G 32GB, it is fully charged but when I turn it on no icons appear except Itunes and a connect cord.  What am I doing wrong?

    The screen that you see is trying to tell you to connect the iPad to iTunes on your computer with the cable that came with it. ITunes will then walk you thru the setup steps. Make sure you download the latest version of iTunes before you connect your iPad.

  • My iPod touch is not turning on its fully charged but it just shut off and won't work i connected it to my mac desktop and it still isn't

    what do i do? do i go get it fixed or what?

    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.
    - Try another cable                     
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Apapter light is green, but MacBook is not fully charged.

    My MacBook's power adapter light stays green, but my computer is not fully charged, the indicator in the menu bar says 98%. I am very confused, anyone have a possible solution?

    The charging circuitry turns off once the battery is fully charged. It will come on again when the charge level drops below 95 percent. Until then the battery is fully charged so the charge indicator on the adapter will stay green.
    If your battery never attains 100 percent charge level it may be because you've never calibrated the battery.
    If you've calibrated the battery but it still will not charge fully or doesn't hold the charge, then the battery may be defective. You can have it replaced under your warranty by taking the computer to an Apple service center or calling AppleCare. Click on the Contact Support link at the bottom of this page for AppleCare's phone number.

  • When i plug in my 5c overnight to charge, it did not fully charge

    my iPhone 5c has ios 8.1.2  the memory available is 7.8gb storage capacity is12.8gb.  when I plug in the charger to charge overnight, it does not fully charge.  my phone was at 40% power last night and I plugged in the charger and this morning it was at only 61% power.  When I plugged it in, the battery symbol did not turn green, nor did it make the beep sound.  What is wrong?

    Are you using a genuine Apple charger and cable? If not, I would suspect there's a problem with either the plug or cable. Also, make sure the outlet you're using is working properly. Did a breaker blow through the night?

    Hi Alcopops,
    Thank you for posting and welcome to the forum. 
    Try to customize the Multimedia Settings of your phone for you to send large size of photos through MMS. Go to Messaging, select Options and then go to Settings. Once done, tap on Multimedia Message and then select Image Size. From there, you will be having an option to change it from small to large. If this doesn't work, consider double checking it with your Service Provider as they may limit the size of MMS messages. If the inserted picture exceeds this limit, the device may make it smaller so that it can be sent by MMS. And also, make sure that the device is running its latest software. 
    Try this and let us know the outcome.
    Cheers,

  • Ipod nano 5th gen - works fine when plugged in either to wall or computer and appears to be fully charged but as soon as it is unplugged screen goes blank and will not start - is the battery shot?

    Yes, your battery is likely toast and in need of replacement.  Not much else for troubleshooting here.  Sorry.

  • My iphone is fully charged but it will not turn on unless plugged into a charger

    my iphone is fully charged but it will not turn on unless plugged into the charger in the wall, it wont even turn on when connected to the computer!!!!!!!

    Hi there. Any luck with your phone? I'm having the same problem

  • 80gb classic screen flashes n wont connect to computer but can play threw a docking radio. says fully charged but it dies when disconected.

    bought ipod used and screen flashes and wont lync to computer or car stereo threw cable. older classic does just fine with cable. i have a rigid work radio that has controls for ipod and the ipod plays, says its charged and i have all functions untill i disconect it from radio. then dead. i would like to save the music thats on it if possable.

    Yes, once I 'safely remove from drive' the ipod works normally I can listen to my media, change settings and even reset it by pressing MENU+center button. During resetting it goes straight onto the screen showing the Apple logo and then retuns back to automatically synchronizing with the computer (since its still plugged in to the usb port) and i can go into itunes and play my media via laptop. What type of servicing are you referring to? Should I try buying a new battery or sending it to apple so they can figure it out?
    Two things which happened yesterday which were sorta demoralizing:
    1 After unplugging my ipod from USBport the screen would automatically go black, right after I would hit the PLAY button and would get the "Connect To Power" Warning screen but under very Low Backlight before shutting itself down again. You could hardly see it, but now it doesn't pop up at all or give me any type of warning just a BLACK screen, so the only way of getting the unit to do anything is via usb connection.
    2. Also the day before I had fooled my ipod into being connected to the usb even though I was pulling the usb cable very slowly from underneath its adapter; sorta letting it touch the adapter but not really hooked up to it. Well I managed to get the cable off and my Ipod to work for less than 10 seconds but I was able to scroll down the Main and Playlist menus without any lag or lack of Backlight before it went out. I tried it once more and it didn't work plus I don;t see what the benefits of doing so would be @ this point. But having said that does anyone think it could be a simple battery issue or is this harddrive related? Again the Ipod only work swhen connected to my usb & tells me its fully charged, but once unplugged it goes completely blank...

  • I have low battery on my ipad and it still works but it is not fully charging what can i do

    i have a low battery on my ipad it still works but it is not fully charged what can i do to fully charge it

    Clean the charging port.
    Charge using the supplied wall charger, not your computer.
    Try another charger and/or cable.
    If none of these work, you have a hardware problem.

  • My ipod touch 4 won't sync or register on my computer. The cord works, the usb port works, and when I plug my ipod into the wall to charge it work, but when i plug it to the computer nothing, not even charging. P.S. worked before I updated it.

    You do have iTunes 10.7 or later on the computer, right?
    See:
    iOS: Device not recognized in iTunes for Windows
    I would start with
    Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
    or
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
    Run this to help if it identifies the cause

    Have you tried on another computer to help determine if you have a computer or iPod problem?

  • After charging my iphone5 for many hours I checked it and it 100% charged but not fully charged as the sign of charging on the top of the screen is still and the sign of unblug the charging cable doesn't show up and this happened several times ...!?

What is the problem and how I fix it !? Thanks in advance :)

    Apple told you it was unrepairable.... You had it serviced by an unauthorized party. It's now no longer eligible for out of warranty replacement by Apple.
    There's really nothing else we can say about it. Find a competent 3rd party repair shop or buy a new one.
