Ok and what do you think of those settings ?
When profil Battery is selected the CPU will alway run at 550Mhz with 0.75V
When Balanced is selected it allows you to reduce CPU temperature while juste browsing on sector or just doing some deskop applications.
When high is selected, in order to play game for example, your CPU runs always at his max speed with an undervolted input which allows CPU to get cooler, but does it affect performances???? I don't know.
Don't you think that it's better than setting manually frequency? Here i just have to change the profil, it's really faster.
And in an older post you said that you are able to get 2h from your battery in dGPU mode, I know that it will be hard with XP but can you tell me how do you do that because i wanna try!
PS : srry for bad english^^ ( French )
It should be beter like that, and don't worry about undervolt it won't reduce the performance at all.» Click to show Spoiler - click again to hide... «

To quote about what I do to increase battery life, and some aother additional tweak:
QUOTE
If you guys wanted to try to save battery further, you could try my untested 'Superleggera' theory:
1) Remove the optical drive.
How many of us use optical drive all the time? With it removed, theoretically there is more air going inside your lappy with back cover closed and the current draw of this drive is 1.5A, it supposed to increase battery life too, I'm testing the former right now, and it seems temperature is only 2-3C higher than with the backpanel removed
2) Disable unwanted stuff, like LAN, in BIOS if you don't use it.
I never use LAN for my lappy so now I disable it. You can disable other stuff like audio if you just wanted to browse in the mamak stall, maybe can further save few more minutes
3) Continue disable unwanted stuff.
I going trully nuts with this, I disable the internal mousepad entirely because I use mouse 100% of the time by disconnecting the ribbon cable behind the keyboard, but this means the L.E.D indicator underneath it won't work anymore. You can disable memory card reader in Device Manager too if you don't use it, and some of the USB port too
4) Reduce the HD4570 clock even further, I get it run at 150MHz core with 200MHz memory. Could try it lower. Use AMD GPU Clock Tool
5) Don't use the battery when you plug to the wall after full charge.
