Ok to get started you will need to shut your MacBook down. So just power it off. Once the Mac is powered off, Press and hold down the Shift, Ctrl and Option buttons are the same time. While holding down these buttons next press and hold the power button for 10 seconds while still holding down the Shift, Crtl and Option buttons.
Once this is done hold your power button down again to start your Mac up. This should now have reset your SMC and any issues that you were experiencing should now be gone.
