I was having trouble sleeping last night, so I lay there and watched the sleep LEDs blink on my two PowerBooks. I noticed that the Duo 2300c blinks exactly 2x as fast as the 540c. I thought this was interesting enough to warrant some questions to people with more PowerBooks and a forum post

So, anybody willing to time the blinking rates of their PowerBooks and post 'em?

540c clocks in at 2 spb (seconds per blink )

Duo 2300c is in at 1 spb.
