Underclocking a Pentium M

Hey there,

I'd really like to underclock my laptop in order to save power. I don't really need all the power of my 1.6ghz Pentium M and I'd like to bump it down to the 800-1200mhz speeds. I've never over or underclocked before so can you please explain to me how to do it? Thanks!
 
You need to play around with your settings in Windows as the Pentium M is able to dynamically slow down the processor speed to save power. I have a few-year old IBM Thinkpad T23 with a Pentium 3 Mobile 1.13 and it clocks down to about 733mhz when on Battery power.
 
i thought speedstep was enabled? try setting the power options in control panel to maximum battery life/minimal power management/laptop setting.

you can also try notebook hardware control, as i think it might let you manually set how fast you want the clockspeed to be.
