my iMac's sleep light dims because of the ambient light sensor located at the bottom knows that it's dark in the room, and in turn dims to let me sleep.
If theres no way for the powerbook to know, there must be some kind of hardware fix.
I don't think there is any way to "fix" this. I mean no offense in any way, but do you have really thin eyelids? I had a rommate once who used to have to cover every light emitting thing in a room. I used to think he was mentally sensitive to the idea of light being in the room... maybe not?
*) It is possible. If you run Linux, for example, the light is used instead to display hard disk activity.
The LED is connected to a PWM output on the CPU, which determines the brightness. I'm pretty sure, though, that you'd need to write a kernel extension -- or maybe even a patch -- to alter the brightness, and I have no idea where to look.
Fortunatlely, the Darwin Kernel is open source, so knock yourself out.
My PB (1.67) has a sleep light which is 1 mm X 3 mm.
It's TINY.
In fact, I find it inadecuate. I loved the Clamshell ibook's sleep light, which didn't dim down all the way and could be seen from the front as well as the back. But my pb can only be seen from the front, and its cycle is long and I have to wait an eternity (relatively speaking) to identify the machine's state.
You can't be talking about the 1 mm slit of white LED light.
The idea isn't to take a hammer and chissle to an expensive computer, nor to hide the state of the machine with permanent marker or tape. I want to be able to identify if the machine is off or sleeping, which is usually the case before I pick it up and transport it.
All I want to do is DIM the thing. LED's can be really bright.
There must be some easy software hack to dim it because when my powerbook sleeps with the lid open, the sleep light dims. It's only when I close the lid that the light becomes more bright.

I leave mine plugged in overnight - the white LED light turns off. The power cable inlet lights up soft green: this isn't as hard on the eyes.
Alternatively, turn your powerbook 180 degrees around.

or
Place it in its bag or whatever
or
Place a sock or a shirt over it at night

Yes, there is. Either disconnect the light or cover it with something.
I'm sure the dimmed light (using the ambient sensor) feature will eventually make it to the PowerBooks, but obviously not in your revision.
So unless you want to hack it on the software side*, just cover the light with a sock.

Um, how? By opening the entire case? You can't access the LED from the outside.

Are you?

Well, you crack the plastic covering the LED, thereby dispersing the light a bit more
Or you can take a sharpie and color the LED area black. Or use an Expo marker and color it, so you get cool colored lights when it is asleep.
All I want to do is DIM the thing. LED's can be really bright.

Or you could just get a piece of white electrical tape, cut accordingly, and lay it on top of the LED.
That would work if the LED was directly accessible.

In Haiku Form:
And we have replied,
Write a Darwin Kernel patch,
Or use thin white tape.
SOL
Thanks for the humorous replies though!
