I was actually able to shut down by hitting the power button and wait for the laptop to power down after the timer ran down. I was also obviously able to take a screen shot using the keyboard shortcut.

The MacBook Pro is a 2.5 GHz Core 2 Duo w/ 4GB RAM. It's got the GeForce 8600M GT video card w/ 512 MB RAM.
