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?
Intel Pentium J3710
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.
