Hmm, on my Toshiba M115, I can't change the brightness in BIOS or at the Toshiba boot screen. In 10.5.2, the 1.4.18.6 AIIFB only made my keyboard/trackpad not work, so I'm back at 1.4.20.28.

According to Toshiba, I have the latest BIOS (v1.50, 3/15/07).

That will make the screen darker, but will it help save my laptop's battery life? And I want to be able to change the brightness.


Anything that darkens the screen will save battery life. in effect, if the full screen is darkened then the lcd backlight dims and uses less power.

"Only CRT displays use more energy to display brighter things. For everything else, it is completely false that a black display uses less energy than a white page. The backlight on an LCD is on for the entire LCD regardless of what is being shown. The black pixels are only black because the LCD blocks out light. Same with projectors, etc."

The kext posted earlier in this thread makes the backlight work on my laptop (lifebook 7230), but when it wakes up from sleep, the backlight is totally off and I can barely make anything out.

How did you change the backlight?

I'm able to control the backlight with the fn-f6 and fn-f7 keys. But only with the kext posted in this thread.

You can setup a new profile in SystemPreferences / Display / Color - Calibrate!
I use the standard Adobe RGB(1998) one but if you set your own up you can reduce the GAMMA!

Its weird I had more than two different notebooks and all of them the LCD Brightness buttons still worked!?

Nope, there is no brightness option? Any more ideas?

Ugh... Yeah I know how you feel. I'm probably going to put the old kext back. I'd rather have working sleep than brightness. Such a pain to shutdown and reboot everytime.

I tried using configuring my laptop to use hibernate, but it keeps going into S3 sleep. :rolleyes:

Yes, that is an option as well as using a program such as Shades. However, neither of those will help increase the battery life and, I don't know about anyone else, but I can tell the difference between a dim screen and one that has just been shaded and the latter looks rather annoying.
