Asus F3sv-A1 UnderVolting

Hi i have an f3sv-a1 and it gets like 1 and a 1/2 hours of battery with everything turned to the lowest or off. and that pretty much sucks, i want a little more battery life.

RAther than buying another battery, i want to just undervolt it just a "little". But idk how. Can someone help provide me instructions step by step using notebook hardware control to help me get like 30+ more minutes of battery?

Sorry is this is posted in the wrong section. Thanks for the help.

 

just turn off sidebar and aero!

Seriously though, there is a great undervolt tutorial on this forum using RMCLOCK. Search for "rmclock undervolt" and it will show up.

My F3Sg (almost the same as yours, but with T7250 and 256MB 9300M G graphics) runs for 2 1/2 hours.

 

You will not get much benefit from undervolting a Core Duo, since the idle voltage cannot be lowered, and (hopefully) the CPU spends most of its time idle.

But there are other things to check/do:
- make sure your CPU is running always at its lowest speed on battery. For instance, you can use RMClock (without undervolting, just frequency control) for that purpose. Power4Gear is also OK if you know how it sets frequencies on various profiles, their names are not always the most intuitive.
- sidebar and aero turning off are not a joke! you will get at least 15-20 more minutes from your battery. There is a program called VistaBatterySaver that turns them off automatically for you. Check my Vista optimization guide for details (signature).
- make sure that the GPU is on a power saving profile on battery power. That is I am afraid an academic point, it appears that nVidia drivers forVista do not offer explicit control for the GPU frequency. (I don't have Vista, so I'm quoting what other people say at this point).
