Warning In this situation if the computer is placed in an enclosed environment like a carrying bag the computer can overheat

You can potentially verify this situation by pressing the caps lock key. If the LED glows, the power manager is actively running on the logic board. If pressing the caps lock key or other methods of waking up the machine have failed, including closing the lid to put it to sleep and reopening it to wake it, hold the power button down for six seconds to force a shut down of the computer. Restart the system to check that it boots up normally.

Note: Given that the keyboard in a MacBook Pro is a USB device, it may not respond when the operating system has crashed. Thus, despite the fact that the caps lock LED does not light up, the computer may still be drawing power. If in doubt, hold the power button down for six seconds to force a shut down of the computer.
