Description: Hmm, neither the Cool'n'Quiet nor PowerNow! programs are compatible with the notebook, but the CPUInfo software on there just confirms my suspicions that it's only running at half its max speed.

Check the windows control panel for "Power Management" my IBM laptop has an "Advanced Settings" tab (Not just the "Advanced" tab) with CPU power management options. Which I can toggle between Automatic and Disable. Beyond this there's IBM software where you can define power schemes such as High Perfomance or Power Saver. Within this are settings for the CPU: Maximum, Adaptive, Slow, Very Slow. Your laptop may have a similar feature.
Run a program that will let you monitor the temperature readings. There are many such programs available, for windows you might try hmonitor .
If you find that your CPU temperatures are excessively high (60 - 70 degrees C or more) then your heatsink is probably gummed up with dust and hair. A bottle of compressed CO2 from the office supply store should be able to blow out all the gunk from the vents without taking anything apart. The chipset or control software will usually throttle CPU speed if it gets too hot, because this reduces the amount of heat generated. But if the vents and/or heatsink are blocked by junk, the CPU will not be able to maintain a low temperature.
This is a funtion of AMD's PowerNow software (their version of Intel's SpeedStep). You can turn it off by changing the Power Profile in the Power Settings Control Panel from Laptop to Always On. Use an third-party application to keep an eye on the temperature of your CPU, and use AMD Dashboard to check the true speed of the processor (the Windows reading is often wrong). If, after turning off PowerNow, you still don't get the expected cycles out of your processor, you may need to upgrade the BIOS and processor drivers for your laptop.
It can be surprisingly difficult to peg a modern CPU to 100% usage. The most reliable way I've found is to run dnetc. Even then, it may not exercise the whole chip. Anyway try running that for awhile and see if your system runs at the speed you expect?
