Force a laptop to run slower?

[magomago]

Hi, my friend hasa 2.66Ghz P4 Presario 2500 and this is one hot laptop..soo much to where having a cooling pad is mandatory (this is even after we blewout a lot of dust from the inside). Often times he isn't gaming or doing anything that requires the Mhz (just loading up PDF answers from HW and cmparing and checking to see how to do it)....and I was wondering if there is any way to literally lock the laptop via softare at a slower speed.

Does anyone kw of any way, b/c power controls yielded nothing...or you need a Mobile Athlon/Centrino to take advantage of underclocking? I already checked his bios to see if i could lower the FSB but the bios doesn't have any options...

Thanks

Not an Intel sorta guy me'sen. But most modern CPU's will auto-regulate their speed dependant upon load, slightly slower but saves on heat build-up and battery drain.

It's a component of the CPU architecture so it's not BIOS configurable.

If your friends turns out not to auto regulate (see Intel site for chips that do/don't) you could run a utility like Rain or CPUCooler - again they incurr a small overhead but may be worth it.

When you say 'Pad' You mean to put on your knee or the HS?

Peace

haha thats fine, i'm not an intel sorta guy either Nope~ a cooling pad...its a thin sheet type thing with two fans in it that suck air away from the bottom of the laptop

my guess is since its a regular 2.66ghz p4 processor...ie:nothng special about it, then it doesn't have auto regular

Rain? or CPU Coooler? Will check it out and post a reply ^^

edit:

seems both rain and cpu cooler are win9x programs...and soething about HLT which winxp already does....

I've been a heavy user of laptops the last few years, and there's not much your friend is going to be able to do. OEMs started the dumb trend of using desktop chips a few years ago. Intel's desktop chips provide absolutely no way to dissipate heat via software configuration on laptops. That's why I advise friends to ALWAYS get a SpeedStep-enabled chip if they're going to be buying a laptop (gaming is fine, and it's actually possible to sit one on your lap without burning your shorts).
