How to enable Intel P8600 CPU VT-x on Latitude E5500 Laptop?

Hi,

I have Latitude E5500 with Intel P8600 CPU, when I check Intel Technical Lists that showed P8600 can support VT-x technology,

But I installed VMware Workstation 9.0.2 & wanted to turn on a virtual machine, It showed error messages like:

And I set to use VT-x

I had already startup Virtualization Technology in BIOS setting & I only installed Windows 7 64bit Ultimate edition in Latitude E5500 Laptop.

How can I enable this CPU VT-x to run virtual machine in Workstation 9.0.2?

Please help me to solve it.

Thanks~
