flupke Posted December 26, 2006 Share Posted December 26, 2006 HiI don't have Windows Vista yet but on my next laptop I will.Does someone kwow wether it is possible to configure in the power options that it has the aero glass interface in AC-mode and the aero or basic interface in battery-mode? I read in articles that the aero glass interface drains the battery faster so this would be an interesting setting.Another question: does the Home Premium edition have all the power-configuration options or is it usefull to pay more for the Ultimate edition?

wfunction Posted January 2, 2007 Share Posted January 2, 2007 It already kinda does that. Go to Power Save Mode and the translucency is disabled, but the rest of Aero isn't. Link to comment Share on other sites More sharing options...
wfunction Posted January 2, 2007 Share Posted January 2, 2007 Help with me writing the program...If anyone here knows VB.NET or C# (or maybe C++.net), then I need some help:I need the DeviceIoControl API to reduce the LCD backlight brightness - but it needs the device name, and when I pass it, it won't work. I use the GetDeviceDriverBaseName function - but I need a good sample to use it correctly. Any help is greatly appreciated (and will probably be rewarded with the program!).

cluberti Posted January 2, 2007 Share Posted January 2, 2007 Found this on channel9 - not using a laptop at the moment, so I can't test, but it might work for you.http://channel9.msdn.com/ShowPost.aspx?PostID=172493 Link to comment Share on other sites More sharing options...
wfunction Posted January 2, 2007 Share Posted January 2, 2007 WOW! Thanks, I'll try and see if it'll work - in a few days or a couple weeks. THANK YOU!!P.S.: I also have problems with disabling devices - an example for that is also helpful. (OpenDriver, DriverProc, then CloseDriver; but the parameters are confusing.)

wfunction Posted January 3, 2007 Share Posted January 3, 2007 I tried - without success.It seems like the CreateFile("\\\\.\\LCD",...) (or whatever that string was) returns -1. Is it always named "\\\\.\\LCD" for laptops, or could it be something like MONITOR, DISPLAY, DEFAULTMONITOR, or something else instead of LCD?

LLXX Posted January 3, 2007 Share Posted January 3, 2007 Do you know what ports on the hardware control the LCD brightness? Tried direct writing to the hardware? Link to comment Share on other sites More sharing options...
wfunction Posted January 3, 2007 Share Posted January 3, 2007 (edited) I'm not that pro at APIs... I just need a template from which to copy and paste - and understand why it works. I am NOT a hardware guy (not even close).*Edit:I have tried API Monitor (without success) to monitor ALL API calls from ALL processes when I press Fn+F6 (which increases my screen brightness). But nothing comes up. Edited January 3, 2007 by wfunction Link to comment Share on other sites More sharing options...
sven Posted January 4, 2007 Share Posted January 4, 2007 How about turning off all the fancy gui? Reduce the high-end usage of your video card to save power. I know that my ati card slows down it's clock speed when on battery, but if you have all that eye-candy running, your card is running like mad.

wfunction Posted January 5, 2007 Share Posted January 5, 2007 Do you mean write a program which will turn off all the eye-candy?That is not as effective as LCD backlight brightness, in my opinion.But I might implement it.FYI: I have ATI Radeon Xpress 200M.

wfunction Posted January 5, 2007 Share Posted January 5, 2007 Here's a question for the poster:Why can't you install the Viao Power Management in Vista? Any error? I could possibly help you Link to comment Share on other sites More sharing options...
