Apple today updated the firmware on the new (mid 2010) 15 and 17-inch MacBook Pros.

The update resolves a rare issue that may cause the system to freeze during startup or intermittently stall during operation, and it improves compatibility with external displays.

Connect up that power cable and hit Software Update or head here if this affects you.
