It doesn't seem to change anything. System is still running hot, idle stats tab in powertop is unchanged and turbo boost doesn't work.

Hello, i installed Coreboot on my x201t but turbo boost isn’t working and cpu won’t go past 2.1 GHz. My processor is an i7 640LM. Something i also noticed is that the system runs hotter with coreboot than with stock bios but i don’t know what’s causing that.
