HP/Compaq :: Where Is The Shader Clock- Dv2700 / 8400M GS

I have been reading the threads related to HP notebooks with defective nVidia GPUs and just out of curiosity, I checked the 8400M GS GPU in my roommate's HP dv2700 notebook, which normally runs @ 80 - 90 deg C, using GPU-z software. The sensor data matched the default core / memory clock for 8400M GS, when under stress. But I got confused when I saw that the shader tab is disabled .

I do not know if somebody else has already come across this situation. I searched here and could not find a similar reported problem, hence this thread. Am I missing something here or is there someone out there having the same problem. Can it be something related to an older ForceWare version (156.65)?
