    Any way to keep my laptop CPU at 800mhz?

    I have a Sager 3880 with a 2.0ghz Pentium M, and under the power settings if I set it correctly I can keep it at 800mhz most of the time but it still fluctuates between 800mhz, 1.50ghz, and the full 2.0ghz. I'm wanting to keep it at 800mhz at all times because it saves battery life when I'm just browsing the internet and it generates ALOT less heat (according to Mobmeter it stays at a steady 40C @800mhz in comparison to 55C even idle when its at 2.00ghz).

    Any help would be appreciated....and sorry if this was the wrong forum to post it on, this seemed to be the best choice of all the categories.

    Nevermind I found the program.

    I had this program about a year ago and couldn't find my model of motherboard so I could never get it to work...I'll see if I can find it now and reply back if I can't.

    Wow, that time I installed it and all of my specs were auto detected, so it works.

    Thank you very much.

    Yeah, you can also do this straight in the windows power modes. Always on is full speed, and max battery is always 800MHz, and the others are a mix in between (exactly what u were experiencing in the beginning)

    But yeah, nhc is great and if it works just stick with that.

    I did the power saving option under power options, but it would still act like Dynamic Switching...switching from 800mhz to 2.00ghz all the time according to Mobmeter. This program did the trick though, and its not going up from 800mhz.

    You can produce even less heat + save on battery by undervolting with NHC. I found 0.732v@800Mhz to be rock stable.

    I use RMClock because NHC doesn't work with Vista.

    I wrote a cooling guide that includes a section on undervolting the Pentium M.
