Hello Jan:
In regard to the problem with the Turbo Boost driver, let me ask you, before doing the Windows® re-installation, did you check with Lenovo directly to make sure that the version of windows installed is fully compatible with your laptop?
Some laptops are not fully compatible with some versions of Windows ®, so that could be the problem.
We do have a turbo boost driver available in our web site, here is the link for you to be able to download it:

After that if the problem remains, the best thing to do will be to get in contact with Lenovo directly so they can assist you with this:
