HP 250 G4 Unlock InsydeH20

Please help unlock bios,so I can access the hidden settings:

Model PC : HP 250 G4 Notebook PC
Bios Revision : F.1F Rev.A
Bios Link : http://ftp.hp.com/pub/softpaq/sp74501-75000/sp74599.exe

My problem: My laptop is very slow. In event viewer I found Kernel-Processor-Power event 37 - The speed of processor 0 in group 0 is being limited by system firmware etc..

Thanks in advance!
