<<Mobile Intel® Pentium® 4 Processors - M supporting Enhanced Intel SpeedStep® technology lets you customize high performance computing on your mobile PC. When the notebook computer is connected to the AC outlet, the new mobile PC runs the most complex business and Internet applications with speed virtually identical to a desktop system.
When powered by a battery, the processor drops to a lower frequency (by changing the bus ratios) and voltage, conserving battery life while maintaining a high level of performance. Manual override lets you boost the frequency back to the high frequency when on battery, allowing you to customize performance.>>

I think this is what yuou are looking for and I believe I have manual overridden it before on my centrino 1.5...so it should be easy to change in the control panel....
So basically plugged in it should always run max speed...batteries it will downclock...
Here you go....
http://www.intel.com/technology/itj/200...e02/art03_pentiumm/p11_performance.htm
you have to go to power options and turn "always on" on....
All system run the Windows* XP* operating system. The operation modes used are as follows:
* Always On (Max Frequency) max all the time...should reduce batery ylife to 1/2 of what it does now
* Portable/Laptop (Adaptive Frequency) meaning max on AC speedstepped on batteries
* Maximum Battery (Min Frequency)
All scores are normalized to the Intel Mobile Pentium 4 Processor - M (orange bar) score. The efficiency?performance over power?is obtained from the benchmark performance score divided by the average processor power for the duration of that benchmark.
Always On Mode
In the Always On mode the processor always runs at its highest frequency. This mode is mostly used when the system is connected to an AC power source. This mode demonstrates the inherent performance and power-awareness of the Intel Pentium M processor without utilizing the Enhanced Intel SpeedStep®
