Daniel :

Hello, my name is Dan.

Daniel :

Usually, resetting the PRAM will do the trick.

Daniel :

Restart then press and hold these 4 keys down, 'Option', 'Command(Apple)', 'R' and 'P' keys, keep them down until you hear 4 startup chimes then let go.

This resets all of the system busses, USB, Optical drive, Firewire, display etc.

Daniel :

As I said, usually this will do the trick. That said, it doesn't always do the trick.

Daniel :

Let me know your results.

Thanks for taking the time. I have tried the reset with the four startup chimes and it hasn't fixed the problem. Any other thoughts?

Expert:  Daniel replied 6 years ago.
The next thing is called resetting the SMC (system management controller), this may have no effect either. It is entirely possible that you have a hardware issue that none of these things is going to fix. Just so you are aware of that.
To reset the SMC first shut the computer completely off.
Disconnect the power adapter and remove the battery.
Press and hold the power button for 5 seconds.
Release the power button and install the battery and connect the power adapter.
Now start the machine up.
This is assuming that your MacBook Pro has a removable battery.
Let me know if that helps.
