Windows XP and Intel SpeedStep

On my notebook computer with Windows XP, I don't have the Intel SpeedStep Power Management applet in my control panel. According to Intel, "Since Windows* XP has the Intel SpeedStep technology driver built into Windows, you will not see an icon on the taskbar and you will not see a tab for Intel SpeedStep technology using the power applet located in the Control Panel."

But if the technology is built into Windows, shouldn't it work? In my computer, if I start the computer plugged in, it starts at 900 MHz. If I then remove the power plug, instead of dropping to 700 MHz, it stays at 900 MHz. But if I star tthe computer on battery, it starts at 700 MHz and stays at 700 MHz even if I plug it in. It does not SpeedStep when I change power while the OS is running.

When I had Windows 2000, this feature worked perfectly, with the speed changing whenever I un/plugged the computer.

Help.

I thought the Intel SpeedStep utility is provided by the laptop manufacturer? When I redo my Sony VAIO laptop from Windows 2000 to Windows XP, I lost the auto-switch feature. Good thing was that Sony released some DLL patches for XP so I can use the Widnows 2000 Sony utilities. Now, I got the feature back.

I have a Toshiba Satellits 2805-S402. I upgraded from ME to XP last fall and was without speedstep until Toshiba got around to rereleasing the various utilities included with my computer for XP. It works fine, now.

I have a dell inspiron with XP and a 1.2ghz p3. You can disable speedstepping, or enable it, by going to the power management part and selecting Desktop or Laptop mode. I think anyway. I can't quite remember because I switched it so long ago, but it will always stay at the high speed unless you switch it back down manually.
