Try the following:

Reset your Mac's SMC.

What: Reset the System Management Controller (SMC) on your Mac- Apple Support
How: Hold down the <shift><control><option> keys, and then, press the power button. Hold all of them for, at least, 10 seconds.

Why: Resets fans, keyboard backlight, status indicator, battery indicator, display backlight, power button, close/open the lid, sleep or shut down, battery doesn't charge, MagSafe indicator light incorrect status.
