Lenovo ideacentre 300S stuck at 0.48ghz

Good-Afternoon,

 

I have a strange problem with my lenovo ideacentre 300s. The cpu frequency is stuck at 0.48ghz and refuses to go any higher regardless of the computer's load. If I change the settings around in the bios for the cpu by disabling EIST and turning off almost all C-states; the processor operates at it's native frequency of 1.60ghz but it obviously won't turbo boost. How can I fix this? Why does this computer act this way?

 

Computer Specs:

 

Intel Pentium J3710

4GB RAM

500G hard drive

Machine Model no. 90DQ004GUS

After further research on the web, lenovo yogas had the same problem as well, which was resolved by a bios update. It seems to be related to a bd prochot signal, which I can't disable in throttlestop. Does anyone know of a knowledgeable lenovo employee on here who deals with bios programming?

just an edit to my first post, disabling eist and turning off c states doesn't help much anymore still reverts back to 0.48ghz. It's quite obvious lenovo knows of the problem if the default bios settings turns these features off.
