In regard to your inquiry, I just wanted to let you know that Intel® does not support any kind of customizations that can be done on the processor, that is why there are no information or documents showing how to downclock or overclock the processor, let me apologize for that, the information you are requesting is not available from our side, the support is done under stock configuratios.
However, there are many pees that will have access to this thread and they might be able to provide further details on this matter.
Also remember that on a laptop everything is customized by the manufacturer in this case Lenovo, so in order to get the information you are requesting to get in contact with Lenovo could be a good option, they might have specific steps t do this, maybe a BIOS update is needed or a BIOS setting needs to be change.
