Hello Lenovo,
You stated:
> 1. change ‘Operating Modes’ setting to ‘Custom Mode’ in UEFI
Are there any modes you may set the UEFI BIOS to allow the CPU scaling scaling test to be created?

Would you be able to list all of the system models tested that are showing this issue?

Thank You
Joe Kachuck

This is configuration wrong.
The p-state setting is nor correct in uefi. 
Thanks Joseph's support.
