CPPC needs to be enabled in BIOS for this and unfortunately that option isn't present.

If you see the thread linked in previous comment, Lenovo has been advised not to enable the feature :/

Seems to work for me at least:

  > cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
  amd-pstate

And, it has a tremendous effect on battery life and the fan speed on the G3. Maybe it doesn't work with previous models?

As the parent said, apparently AMD recommended not to enable it for that generation [1]. That's the price to pay for having a first gen I suppose...
