Software for limiting CPU power when running on battery

[CHiWuaN]

Hi all,

I just bought a Dell Inspiron 9400 (I believe the E1700 is the equivalent in the USA) to replace my old Toshiba M15-S405.

What I loved about my old laptop was the app for controlling the power profiles and limit CPU when running on battery. That would enable me to tweak my 3 year old battery to make it last 3 hrs by lowering the CPU to its minimum. However, my Dell laptop lacks this control, and battery runs very fast.

This laptop has a Pentium Core Duo 1.83Ghz, so Speedstep should be available. Is there any way I can tweak the CPU power consumption? I'm using CPU Idle, but it isn't quite as good as the app from my previous laptop.

Any help would be appreciated. Thanks,

I have used Rightmark's CPU clock utility on my laptop...it should help you with your battery problem.

Scroll down to "RM Clock Utility" and download.

Not sure if Speedswitch Pro works for your CPU but it's what I use and my Turion isn't listed on their supported CPU list.

I just tried Rightmark's, seems to be doing the trick and I'm starting to love the levels of customization available.

Thanks!
