New T14 I5, CPU still on 0,8GHz, even on benchmark tests

2020-08-02, 7:16 AM

All updates installed both, in Windows and Lenovo Vantage.

 

Tried on Lenovo preinstalled system and the Windows downloaded from MS. 

 

Lack of CPU managment options in Power management window.

Same Issue. The only solution to install throttlestop.exe and uncheck "Disable Turbo" box.

Have you tried going into BIOS and hitting F9 to load default settings and save and exit and test?  You can go back into BIOS and change settings back afterwards.

 

Are you set to "best performance" on windows power slider?  Are you plugged in to AC or running on battery?

Are you using by coincidence a hybrid docking station ? We have seen similar issues with our L380 yoga's: when charging them by means of a docking with usb-c cable, the cpu drops to 0.4 Mhz until the battery  is fully loaded. If you charge them without a docking station, everything runs normal. In our case we could fix it by reinstalling Windows :-/.
