1.4 centrino stuck at 600 Mhz
 

I bought an Asus M2400N 1.4 centrino a couple of weeks back and it is always running at 600 Mhz for some reason. Anyone have any ideas on how to fix this? I'm running XP Pro by the way.

Well, though I honestly have no clue at all. I would check BIOS and see what speed your memory is running at first. Im not sure what Centrino is supposed to be running for memory clock but its worth a shot!

do you use it plugged in or running on battery

I checked the bios. The power was set at automatic i think, so i changed it to max performance and it went straight to 1.4. Thanks

WEll, it seems to be fiexd, but check your cooling fans anyway. Don't want a nice new processor frying itself because of an easy-to-fix issue

I made sure the temp was fine. It was never above 40 degrees. I think its cause of Asus' stupid way to save power. They do everything to not engage the fan, as the fan uses too much power. They even throttle the processor speed before they kick in the fan. The fan is only supposed to come on on the highest power setting

The idea behind centrino is to turn the performance down when running on battery to save power. My T40 does the same thing. When you plug it in though, it reverts back to its full clock speed.

To force it to run at full speed, you need to change your Power Scheme to "Always On" in the Power Options.

It's called speedstep usually. Most newer laptops have some variant of it. Properly configured it should reduce your processorspeed(and batteryusage) on battery and give you full blast with the wall plug connected.

Check both bios and my computer -> properties -> advanced -> power settings.

If you've reinstalled your laptop you may have to install drivers to get it to work properly. On my dell x200 they had bundled speedstep/hibernate drivers with the graphic driver(how.. logical).

With that speedstep thingy, should it drag my processor speed down to 600? That seems like a big drop to me

Yes, it will go that low. SpeedStep is a feauture which extends battery life and lowers temperatures for the cpu by slowing it down. Especially when you aren't doing anything intensive, you really don't need to be running that quickly, which is why SpeedStep will turn your cpu down.
