HackBook Pro Posted October 5, 2007 Share Posted October 5, 2007 Is there anyway to change my laptop's lcd brightness? I have a Toshiba Satellite A105-S4114, and when using OSX my battery dies quickly because of the brightness being all the way up. Is there any way to lower the brightness?

~pcwiz Posted October 8, 2007 Share Posted October 8, 2007 Check your laptop manual. You probably have to press some key combo to change brightness. Link to comment Share on other sites More sharing options...
HackBook Pro Posted October 8, 2007 Author Share Posted October 8, 2007 Fn+F6 or Fn+F7..... That's how I change my brightness. But in OS X that does nothing... Any other suggestions? Has anyone else gotten screen brightness in OS X? Link to comment Share on other sites More sharing options...

Has anyone else gotten screen brightness in OS X? May be different for yours, but on mine Fn and the down arrow decreases brightness, Fn and the up arrow to increases it. ~mac.nub Link to comment Share on other sites More sharing options...

~pcwiz Posted October 9, 2007 Share Posted October 9, 2007 Just an idea but maybe set the brightness to the desired amount in Windows or some OS that works with that and then boot back into OS X. gmodfan, Stop tricking people into getting you a free iPhone with that Click here link in your sig.

mac.nub Posted October 9, 2007 Share Posted October 9, 2007 No, has always worked out of the box for me. Can't think of anything else to suggest ~mac.nub Still nothing.... do i need a special kext file or something? Link to comment Share on other sites More sharing options...
J_Zar Posted October 9, 2007 Share Posted October 9, 2007 No, has always worked out of the box for me. I've the same issue. Sony Vaio Vgn-n21s with GMA 950. I can manage brightness in another OS but Mac ignores the hardware value and set brightness to the top. Someone does know how to adjust it?

Cyp Posted October 15, 2007 Share Posted October 15, 2007 Same for me on my Samsung r55 Aura Clayton. No Options for changing brithness in OSX. But during booting when the white screen with apple logo appears i can change brithness. What's your OSX Version? Link to comment Share on other sites More sharing options...
HackBook Pro Posted October 15, 2007 Author Share Posted October 15, 2007 I have OS X 10.4.10. I also have Vista, and in Vista I needed to install a program from Toshiba to change my brightness. Besides OS X and Vista, I have Ubuntu installed, and in Ubuntu my brightness is also changable. Has anyone been able to change the brightness on a laptop in OS X?

Nitramusa Posted October 16, 2007 Share Posted October 16, 2007 http://www.versiontracker.com/dyn/moreinfo/macosx/31515 The software is called Shades, i use it too on my Acer laptop with OS X Im amazed that nobody else heard about this program.. It's a very handy program to change brightness settings... Hopefully i helped you! Cheers, Nitra Link to comment Share on other sites More sharing options...
Cyp Posted October 17, 2007 Share Posted October 17, 2007 But shades won't help you to save your power. It adds just a dark overlay to your screen... Link to comment Share on other sites More sharing options...
HackBook Pro Posted October 17, 2007 Author Share Posted October 17, 2007 But shades won't help you to save your power. It adds just a dark overlay to your screen... Exactly. I downloaded shades, and it's a nice program, but will it save battery life, which is my main concern? Link to comment Share on other sites More sharing options...
Nitramusa Posted October 19, 2007 Share Posted October 19, 2007 Yeah logically it will save battery life Link to comment Share on other sites More sharing options...
J_Zar Posted October 19, 2007 Share Posted October 19, 2007 Sorry to say black... But Shades does not help battery life. It uses a black overlay but the lcd brightness is always set to the top. This is the reason for having 1000 threads about lcd brightness not working. The real problem is gma950. This driver is build for mac-mini, and mac-mini has not a laptop lcd....! The AppleFrameBuffer seems to override the brightness value every sync. We need a patch to gma950 and I actually am not able to write it. Link to comment Share on other sites More sharing options...

HackBook Pro Posted November 3, 2007 Author Share Posted November 3, 2007 If the MacBooks had the GMA 950, why is there no way to change the LCD brightness? Link to comment Share on other sites More sharing options...
Ferret-Simpson Posted November 3, 2007 Share Posted November 3, 2007 It's NOT because of the GMA945 chipset, actually. It's because the driver only supports one profile of LCD panels. This could be changed by editing the AppleBacklight plist, but what's in there is unintelligable - so hacking it would be "fun". And don't bump topics waiting for other peoples help, keep hacking and adding things you find out yourself. What I just told you took 40 seconds to find out.
