please assist with issue for CPU clock ratio stuck on 8x in my Lenovo T450 mt:20BU.
CPU Intel i5300U 2.3GHz Broadwell Y is installed.
After manual performance setting in Power Manager (system was running on battery) it stuck.
BIOS is the latest one 1.19
OS Windows 7 Pro ENG.
BIOS re-flashing, downgrade to versions 1.18, 1.17 was done.
Full system power off with disconnecting power supply, external battery, internal battery (from BIOS menu).
If there is any other methods to drive ratio besides Power Manager.
ThrottleStop 6 is not supporting this CPU.

UEFI reset to defaults and disabling Speed Step function were done already too.
Does it mean that system board/CPU need to be replaced?

Sorry for mistake, cpu power management was disabled previously, and it did not affect on issue.
Only after setting to disable Speed Step tech. CPU is running on x23 ration 2295 MHz (100%) and there is no possibility to change its speed/ration.
