I recently brought a laptop from a UK manufacturer. The processor inside is an AMD Athlon 64 3400+ (agreed on by Windows XP Home Edition) however, all checks that I run on it (not the unreliable properties of 'My Computer' including System Information (MS) and CPU Speed (third-party) and the Linux Kernel report that it's running at 800 Mhz instead of 2.2 Ghz.

Is this a problem with the laptop itself, a configuration problem, or a reporting error from /all/ involved systems?

Thanks in advance,

D.

-- Edit --

By the way, the Windows Ive just discovered I can force to be faster by turning the power management off with a downloaded tool. However does anyone know of a method of turning off the power management for Linux?

check your bios. There may be a way to disable it there. I'm sure you know by now but in case you don't you have 'Powernow!' enabled. It slows cpu down when not stressed and saves battery power. If your mostly connected to a power outlet then you want it disabled. When cruisin and working you'll want it on to maximize battery life.

This feature is called Cool 'n' Quiet, it slows down the speed and the voltage of your CPU, when it's not stressed.
Run Folding@Home in the background (enable power managemend first), then check with CPU-Z or WCPUID or something, and your CPU will be running at full speed.
