Windows XP: Q330512 Hotfix - The Processor Performance State

Rancho* at warp2search.net has got his hands on the Processor Performance State Is Not Restored to the Maximum State If the CPU Runs at 100 Percent HotFix!

This problem may occur if the power policy changes because of an AC/DC transition while the computer is using the "Max Battery" power scheme. When the computer is running at 100 percent CPU usage, the computer never enters the idle loop in which the speed of the CPU is dynamically adjusted based on demand and current policy values. The fix is to set the timer so that Windows changes the speed of the CPU when the timer expires.

Worth getting... my Compaq 2810T doesn't restore to its full speed if I disconnect the plug, run on batteries for a bit then plug it back it. Seems to work well so far.
