i've got a cpu resource issue, everytime i log-in to windows. It all stays at >25% of cpu usage even if it is in an Idle state!. That cost me 73w of consumption and thats alot, instead it won't clocked down and it all stays at 2.9ghz even i only have little to minor cpu application. I already set all the power schemes to balanced mode and to the graphics properties too. And also to BIOS it says eist, and c-state enabled.
CPU-Z ver 1.54 might be more accurate because it covers I7 and I5 cpus. Instead of CPU-Z why not use Intel's own program.
