HELP! What does holding down power button do during boot?

[bradsdad]

My wife held the power button down on her pismo when starting it up, thinking she needed to hold it down til it chimed or lit up. It made a longer, loud buzzing noise (a deep beep). What did this do?

We are having issues now with airport reception (with had been excellent til now) now so I am trying to troubleshoot in a hampton inn here on the road.
