Reset the System Management Controller to Fix-

1. Shut down Mac and connect it to your MagSafe adapter and a wall outlet as usual.

2. Hold down the Shift+Control+Option+Power button for a few seconds at the same time.

3. Release, then boot the Mac as usual

Method-2:

Try a Keypress Sequence to Fix-

1. Press the Power / OFF button once – this will bring up the dialog box which you can’t see

2. Press the “S” button – this is the shortcut to sleep the Mac

3. Hold down the Power button until a hard shut down is forced

4. Wait about 15 seconds, then hit the Power button again to turn it back on.

Hope this might help you.
