you can swap that CPU over with Intel® Core™2 Duo mobile processor T7300/T7500/T7700
You may come into some issues with actually changing over the CPU as laptops are not designed to be upgraded in the same way a desktop would be.
FYI, 1000 Mhz is 1 Ghz. I Im guessing you got those mixed up but that's ok =)
Thanks for that reply. Yes, finger trouble, with my G's and M's getting mixed up.
