6. Reset SMC or T2 chip

The Systems Management Controller (SMC) controls the power flow, temperature, keyboard, trackpad, display, fans and so on. Resetting the SMC is another possible quick fix to resolve a black screen on MacBook Pro.

Follow these steps to reset the SMC on a pre-2018 MacBook:

1. Press and hold the power button for 10 seconds to ensure your Mac is off.
2. Connect the charger, and hold the Shift, Control, Option and Power keys for 10 seconds.
3. Release all the keys.
4. Press the power button again. Now you have reset the SMC.

Apple integrated the SMC chip into the Apple T2 Security chip starting in 2018. Follow these steps to reset a MacBook with a T2 chip:

1. Press and hold the power button for 10 seconds.
2. Press and hold the Control, Option and Shift keys for 7 seconds.
3. Then press and hold the Power key. 
4. Keep holding all four keys for another 7 seconds then release all keys.
5. Press the power button again. Now you have reset the T2 chip.
