+1. I'm going to expand on this further
awake. The current scheme is already at its lowest it can be. Jump to
the lowest setting and then put the cpu to sleep. Any deviation from
that will use more juice. If you wake up the CPU to do something you
have taken a large step backwards.
Actually, there's more we can do to save

I could be talking nonsense, and perhaps this would consume more power
than it saves, but if you were able to slowly dim the backlight over
the course of a minute or so, instead of waiting a minute and then
dropping it suddenly, we could prevent the sudden change which causes

How well we can do that isn't clear.
We have 16 brightness levels, but we didn't think about making them
logarithmic in response to correspond to the eye's behavior, so there
are really fewer than that that are useful.
Please experiment and see if it is helpful, of course...
Hello all,
This is somewhat on-topic, as this code can be used to test the smoothness
of diming the backlight by editing SLP in the included code.
I originally wrote this as I'm planning on using an XO motherboard/screen as
an alarm clock, and will have the brightness set via some fancy HR=$(date

Hi,
as a G1G1 user one annoyance of enabling power savings is the
screen dimming while I am reading a page. I thought this was
supposed to be improved, but I saw the same thing when I upgraded
to 767 a week ago.
There's a way this could be improved. We previously had to dim the

The OS X dimming is more than 10 seconds, but not much more. OK, it's
rather lame to make that assertion on a MacBook Pro without timing

Hi,
When running on battery with Energy Saver set to Better Battery

On AC with the equivalent setting it's 2 minutes, 30 seconds. In
