A firmware update has been released for the MacBook Pro that resolves an issue involving the laptop randomly shutting down during a heavy workload. MacBook Pro SMC Firmware Update 1.5 is now available in Software Update, although Apple has not specified which MacBook Pro models get the fix.

This update resolves an issue where a MacBook Pro being used with a power adapter may unexpectedly shut down under heavy workload if the battery charge level is near empty.

Your computer’s power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.

When your computer restarts a gray screen will appear with a status bar to indicate the progress of the update.

Your computer’s fans will run at full speed during the update but will return to normal speed once the update completes.

Do not disturb or shut off the power on your computer during this update.

The best thing to do would be to check Software Update, but you can also download the update manually from Apple’s support site. You must be running at least Mac OS X 10.6.8.
