How would laptop power button affect hardware scan during Linux bootup?

I have a HP Pavillion dv6500 laptop. When I boot ubuntu live USB, the bootup process hangs indefinitely at around the point where it's scanning hardware.

Then when I quickly press the power button, the bootup process continues. (obviously I'm not holding down the power button long enough to shut it down)

What signal would a laptop power button send that the bootup process (hardware scan) would be waiting for?

You could try disabling ACPI. Assuming the boot menu is the same as the normal CD, take a look at this page.
