It's working here with that. How do you know it's disabled?
Install the Power Manager application and turn slider to left for more performance for a simple way to control this.
Or you can manually change windows power options manually to do the same. Be plugged in when testing this.

Because if I install the power management driver 1.6 , the cpu can not be over 2.66G hz, but when I uninstall it, then the cpu can be over 2.67, almost to 3.2 Ghz when I run some tests.

I use the Intel Turbo Boost Technology Monitor to monitor my cpu.

I've found in past testing with Power Manager (PM) that if CPU is set to Adaptive or Max Performance, then Turbo will kick in. If CPU is set to Low or Lowest, then Turbo never kicks in. Same idea with Thermal Management. These two seemed to drive Turbo capabilities.
If you are using PM, try fiddling with these settings, and watch performance on the Turbo desktop gadget (above). Of course you'll need an intensive application (like PM or ThinkVantage Tolbox) to stress the system in order for Turbo to kick in.

Thanks! When I use the default 'Max Performance', seems that the cpu performance cant be set to max, and the TURBO is still disabled, but when I set up a new plan, and the cpu performance can be set to max, and the TURBO kicks in !

Good news. Turbo is nice, eh?
I should mention I use "reset to defaults" most ThinkVantage tools. PM settings and BIOS settings appear to share these settings and may overwrite each other. Reset to defaults seems to clean things up somewhat.
