Hello everybody. I can't get my laptop operate at CPU turbo frequency any more!
I got my Z710 with windows 8.1 preloaded. The laptop came with Intel's i7 4710 MQ CPU (2.5 GHz base freq, 3.5 GHz max turbo freq) and I could let the processor go up to the turbo frequency using lenovo's pre-installed energy manager software. I then upgraded my OS to windows 10 through microsoft update, keeping the energy manager which was compatible with the new version of windows and everything kept working OK. With the energy manager's high performance option, CPU single core frequency went up to 3.49 GHz (tested with CPU-Z and Si Sandra). However, after getting a new SSD I did a clean install of windows 10 and tried to do the same thing with windows built-in power management (since lenovo doesn't provide a power manager for windows 10 as far as I know) and it doesn't work. With the "High Perdormance" option and minimum processor state = maximum processor state = 100%, the speed never goes over 2.5 GHz.
Is there some extra configuration I need to make or do I need extra software like intel's XTU or something like that?
Any advice would be greatly appreciated.
