Dell Latitude D600 stuck at 598Mhz?

So a laptop I gave my brother a while back has been running a lot slower than it used to.

Back in the day, I used to use SpeedswitchXP to control the CPU speed.

I have a feeling it got 'stuck' at the slowest speed, being 600Mhz. The CPU is a Pentium M (Banias) 1.3Ghz.

Even after a reformat, and clean install to Vista, it's still stuck at 600Mhz according to CPU-Z, even plugged into the wall. The Vista Processor subscore ends up being 1.7.

SpeedStep is enabled in the BIOS, which it's supposed to. I tried turning it on and off without much luck.

Any ideas?

BTW, this is a big problem it seems: google search

What is the power saving mode that is set in Vista?

Set it to full power, and try again.
 
Of course I have it at high performance 🙂

I have a feeling it's more than just a software issue...
