How do you control Intel Speedstep in windows XP?

[codyw1996]

have an idiotic laptop that apparently has no notion of its attachment to an external power supply. It just constantly tries to save battery power even with the battery removed. It has a 2.2 Ghz processor that usually sits at around 600mhz. Sometimes even when doing demanding tasks. There are no options in the BIOS to disable Speedstep or adjust the performance in any way. In Windows 7 there is an applet in advanced power settings that allows you to disable this feature and set your processor to be constantly 100% which is what I want to do with windows XP. Battery degradation is not a problem since I remove the battery when it isn't needed and my laptop has a really nice fan and heatsink so heat isn't an issue.

Have you tried this?

Start -> Control Panel -> Power Options

Under the power schemes tab, select "Minimal Power Management".

UPDATE:

Under Microsoft Windows XP, SpeedStep support is built into the power management console under the control panel. In Windows XP a user can regulate processor speed indirectly by changing power schemes. The "Home/Office Desk" setting disables SpeedStep, the "Portable/Laptop" power scheme enables SpeedStep, and the "Max Battery" uses SpeedStep to slow the processor to minimal power levels as the battery weakens.

Yes I've already done all of that. But it didn't change anything.
