I bought EliteBook 8740w laptop yesterday. Hyper-threading is not working on windows although I enabled it from BIOS. I have windows 10. Also, when I stress the CPU using CPU-Z program, it doesn’t go up to 2.8 GHz as stated on Intel’s website. It just goes to 1.7 GHz. During normal work, sometimes it goes up to 2.4 GHz but this is rare and not most of the time. How can I enable Hyper-threading and uses the maximum of turbo-boost feature.
