present CPU is T2300 running at 667 MHz FSB;

intend to upgrade it to either T7100 or T7300 running at 800 MHz FSB;
will the notebook boot ?

Modern laptops are not designed to have their processors upgraded. The motherboards are proprietary, so unless Lenovo guarantees the processor will work, it may not. You will probably also have a heat problem since laptops are designed from the ground up for efficient cooling.

A processor upgrade is not likely to make much of a difference in performance on a laptop, and the risks are significant.

If you want to improve performance, upgrade to a solid state hard drive.

I am not looking for performance but instead a CPU that supports VT

[DoubleHelix]

I don't think that's a function solely of the processor. I think the chipset and motherboard factor into hardware virtualization support.

[sulasno]

the chipset is a 945PM

[win2kpro]

The 945PM chipset only supports processors with a 533MHz. or 667MHz. FSB.

[sulasno]

that's why I am surprised at the CPUs

T7100/T7300/T7500 run at 800 while

T7200/T7400/T7600 run at 667
