as far as I know, the sleep LED on the powerbooks has nothing to do with the inverter circuit (which instead drives the fluorescent backlight for the LCD display). so swapping the inverter module between models of PB should have no effect on the pulsating or blinking sleep LED

I believe the pulsating or blinking sleep LED is instead controlled by the Power Management Unit (PMU) chip on the logic board.
