Dim the (early 2008) MacBook Pro's sleep light Laptop Macs
I'm not sure on how many laptops this works on, but on my early 2008 MacBook Pro, when the computer is asleep with the screen down, the pulsating sleep light is quite bright. In the older G5 and first intel iMacs (and I'm not sure which other models), when the computer is asleep in a dark room, the light dims right down.

The hint is to put your computer to sleep using the Apple menu, or the power button if you have it set up that way. Then leave the screen open and allow the computer to make use of the light sensors in the speakers. This will then make the flashing light dim. It seems that closing the screen turns the light sensors off, and the light shines at its normal brightness.

Dim the (early 2008) MacBook Pro's sleep light

I've noticed the same thing with my new MAcBook Pro. Also the the LED light comes on steady when the display is turned off (not flashing) and and brightness of the LED is based on the sensor. Really cool.

This is the correct behavior. The sensor is near the keyboard, and closing the cover would cause it to always assume darkness and dim the LED.

The engineering decision was to run the LED at full brightness when the lid is closed, because the sensor is blocked.

That doesn't make sense. The LED brightness was a hack on top of the existing system; and it wasn't an "engineering decision" to disable the sensors when the lid is closed. An "engineering decision" would have moved the sensors to the outside of the case.

Besides, ambient light can change while a machine is asleep. Say, day turning into night... or heck, the opposite (not that I ever see *that* happen).

Anyway -- it proves it can be handled through software. Next task is to make it useful when the machine's awake; like YDL does.

'make it useful when the machine's awake; like YDL does.'

Wondering exactly what it is that YDL (Yellow Dog Linux for those not in the know) does with the light, and what's useful about it.

Thanks for any clarification you can provide.

I'm going to try this one out for sure.

I only sleep in the same room as my Mac when I'm in hotels but sometimes I think the light is pretty bright, would be nice to have it dim a bit then...

I just put a sock in front of the light to block it.

I too use a sock. What if we associate and start a brand new product?

Newbies use socks only for ipod... Join us, buy a MacBookSock(c)(tm)!

This works on all macbook pros and i would also assume with the backlit keyboard powerbooks as well. It uses the ambient light sensors under the speaker grills for the brightness of the screen, keyboard and sleep light.

Works on older Powerbooks, too
Authored by: borgendorf on Jun 11, '08 01:25:24PM

I've noticed the same behavior on both the 15" and 17" aluminum PowerBooks G4s. I never thought about it being the light sensor before, though.

It's not the light sensor
Authored by: a1291762 on Jun 17, '08 07:07:09AM

The light sensor doesn't run when the box is asleep.

It's quite simple really. When the display is open the light is dim. When the display is closed the light is bright.
