Marcin541 Posted July 25, 2007 CID Share Posted July 25, 2007 I would like to know if there is a way for the laptop to automatically change the power plan if the computer is plugged in, or running on battery. How does it work? Do i need to use a special program? Link to comment Share on other sites More sharing options...
Swimmer Posted July 26, 2007 CID Share Posted July 26, 2007 I believe that is part of power management built into the OS.. Dell, for example, also has QuickSet which monitors the battery to see if it is being used or if the computer is running from AC power.. Then QuickSet selects, based on some pre-defined schemes, the best scheme for what you are trying to do with the computer.. However, there is also hardware versions of this.. Intel and AMD have speed stepping capabilities. Which means based on the usage of the computer, the PC and actually cut power to parts of the processor, thereby reducing the overall speed but at the same time reducing the overall power consumption. Intel, with it Centrino platform, also is able to adjust the front side bus speed and a few other things that make it more attractive to the mobile user.

disturbed Posted July 26, 2007 CID Share Posted July 26, 2007 go into control panel and it should be under power management...i think vista has pretty decent power management capabilities...you are able to change what you want + much more Link to comment Share on other sites More sharing options...

Marcin541 Posted July 26, 2007 Author CID Share Posted July 26, 2007 There are only options to change it overall, i mean if i change it to high performance, ya the LCD brightness goes up, but when I unplug the power, there is no change. What I want it to do is change to the lowest performance one while on battery... Link to comment Share on other sites More sharing options...

Marcin541 Posted July 26, 2007 Author CID Share Posted July 26, 2007 Ill have to look around at it some more then, i have another laptop which you dont even have to configure or anything, it just automatically sets cpu and lcd brightness as you plug/unplug it.

php Posted July 26, 2007 CID Share Posted July 26, 2007 What if you turn down the brightness manually when it's unplugged? Link to comment Share on other sites More sharing options...
disturbed Posted July 26, 2007 CID Share Posted July 26, 2007 You can set brightness to whatever level you want both for plugged and unplugged......i go the absolute minimum, not because of battery life but because its just too bright for me Link to comment Share on other sites More sharing options...
Marcin541 Posted July 27, 2007 Author CID Share Posted July 27, 2007 The brightness is least of my problems. I am talking about the processor speed. Link to comment Share on other sites More sharing options...
disturbed Posted July 27, 2007 CID Share Posted July 27, 2007 actually the brightness of a monitor can affect the battery life quite a bit Link to comment Share on other sites More sharing options...

rammolo Posted July 28, 2007 CID Share Posted July 28, 2007 Hi Folks, I have an acer 5100, with Vista pre-installed, have the same problem, it doesn't look for a different power profile while in battery power, though i can easily switch profiles manually. --rammolo Link to comment Share on other sites More sharing options...
