If I were to guess it's either a bios setting or what they call a helper application but this issue can be caused by folk changing BIOS settings, a virus/malware issue or folk that used registry cleaners or got caught up by that talk about crapware and deleted some app or file that was needed for this function.

A restore to the factory condition is likely if the damage can't be fixed and since this is custom and not a stock feature of Windows, only Lenovo may have a fix short of a restore to the factory condition.
