Inverter Boards and their different blinking habits

History

Howdy all! I know quite a bit about Lombard PowerBooks and Pismo PowerBooks, but I don't know the answer to this question.

I'm pretty sure that the inverter boards for each model is compatible with one another, but I know that the Lombard sleep like blinks a green light, and the Pismo's green light fades on and off.

If I put a Pismo inverter board, then the Lombard would have a fading light, wouldn't it? Likewise, if I put a Lombard inverter into a Pismo, the light would blink instead of fade, correct? Thanks so much!

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.

I could be wrong but IIRC the inverter boards are logic board specific. Ralph

rj713,

Ahhh, so you're saying that though the light is actually on the inverter board, the style of blinking is NOT controlled by the board itself? Thanks so much!
