What does it mean when the computer won't turn and and it's been charging. The light on the charger is red. Instead of green


Mac Pro, iOS 6.0.1

    I thought it looks more orange, but that means it has not finished charging yet.

     

    Try an SMC reset:

     

    Resetting the System Management Controller (SMC)

     

    Resetting the SMC on Mac portables with a battery you can remove

     

    1. Shut down the computer.
    2. Disconnect the MagSafe power adapter from the computer, if it's connected.
    3. Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
    4. Press and hold the power button for 5 seconds.
    5. Release the power button.
    6. Reconnect the battery and MagSafe power adapter.
    7. Press the power button to turn on the computer.
    Still having problems? Replace steps 6 and 7 with the following:

     

      6.  Reconnect MagSafe power adapter.

      7.  Press the power button to turn on the computer,

      8.  Then reconnect the battery.

     

    Resetting the SMC on portables with a battery you should not remove on your own:

     

    1. Shut down the computer.
    2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    4. Release all the keys and the power button at the same time.
    5. Press the power button to turn on the computer.

    Actually when the light on the charger is Red it means not to unplug it because the battery is below 10%. The Orange is when it is still charging but not yet finished. Green is fully charged. Think of traffic lights and signs.

     

    Red = No, Stop…………….. Don't unplug the charger
    Orange = Caution………….. You can unplug the charger but watch the battery or I'll turn off on you.
    Green = Yes, Go…………… Yes you can unplug the charger without worry.

    The charger light is not like a traffic light.  It only has two colors, Green and the other one (Call it red, orange, amber - take your pick).

     

    Ciao.

    I thought my color vision was failing. THANKS! You reply was very concise and informative. I didn't need to reset SMC though.

    You got it right. Somebody should take points away from Oglethorpe for his false reply!
