I was having a problem with the green light coming on a few weeks ago, but removing the charger from the computer and replacing it, or giving it a minute would fix the problem and charge my computer.  I went to charge my comeputer after not using it for a week or so and now the green light will not come on at all.  My comeputer won't turn on either.  I completed all of the troubleshooting for the MagSafe adapters, and still nothing.  Ever switching to the 3 prong plug in did not fix the issue.  Does this mean that there is something more serious wrong with my computer?  Does anyone have a tip for me?

    Troubleshooting MagSafe adapters does not specifically mention an SMC reset, but it may be justified according to the following:

     

    Power

    The computer doesn't respond to the power button when pressed.

    A portable Mac doesn't appear to respond properly when you close or open the lid.

    The computer sleeps or shuts down unexpectedly.

    The battery does not appear to be charging properly.

    The MagSafe power adaptor LED doesn't appear to indicate the correct activity.

     

     

    The procedure for an SMC reset follows. Read all the steps, even if they do not seem important or applicable.


    Before Resetting the SMC

     

    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.

     

    1. Press Command + Option + Escape to force quit any application that is not responding.
    2. Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    3. Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    4. Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.

     

     

    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:


    1. Reconnect just the MagSafe power adapter.
    2. Press the power button to turn on the computer,
    3. 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 it's 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.
