Thanks a million for your easy to implement solution.
Not only did this enable the turbo boost function, but it also brought back the 4th core of my i7-3610QM processor which did not work before.
I don't know how this checkmark got there, nor why the number of processors was limited to 6.
I am running on the W7-64 which I had cloned from a previous laptop with a two-core processor.
Keep up the good work
