Also, in the msconfig boot options to start Windows 7 with more cores, with my last lap I had the option to use 4 cores, while in this one only 2 cores appear. Both laptops have the same i5 430M CPU, what could be wrong? i5 is a quad or a dual core?
It's two cores with hyperthreading, so perhaps hyperthreading is disabled in the BIOS? Which would be dumb.
