When on battery, my X1 Carbon with i7-5600U exhibits really poor performance when loaded. Instead of setting a clock to around the base of 2.6 Ghz and run (if I force it using ThrottleStop to stay there it is happy at around 75 deg C), it constantly cycles between ca 2.9 Ghz and 0.8 Ghz every few seconds.
I have tried different power schemes, reinstall/remove Lenovo Power tools, BIOS settings, ThrottleStop, but I cannot force the SpeedStep to work properly. It is working correctly when plugged-in. Anyone knows how to help it? Thanks! P.
