I received a call today from work (it's a holiday for me) concerning a problem with a 17" PowerBook. The caller reported that the user's laptop was locked up and to help them, held down the power button to force a restart. Unfortunately, they held the power button down until the firmware update tone came on. Of course, there was no firmware software to be installed, so they shut the Mac down and tried again. Now, every time they press the power button to restart, it returns to firmware installer mode. How do I cancel this firmware update cycle? I've tried having the caller remove the battery, power cable, and holding down the power button for 5 seconds, but that didn't help. I'll be working on this laptop tomorrow, so I'm wondering how to proceed. I'm not even sure I'll be able to startup the PowerBook from an external hard drive, since something in the hardware seems poised to execute. This is a 2-year old 17" PowerBook running Panther 10.3.9. Thanks in advance for any ideas.
