---------------------------------------- Bug #642: x201t Turbo boost not working, CPU running hot https://ticket.coreboot.org/issues/642#change-2270 * Author: Janez Novak * Status: New * Priority: Normal * Category: chipset configuration * Target version: main * Start date: 2026-05-03 * Affected versions: main * Related links: Are C-states properly working? If not that would explain high temperature and non working turbo mode. Can you please share full coreboot + kernel log? What does `powertop` say? Does the CPU enter C1-C7 states? Looking at the code I don't see configure_c_states() in the CPU driver, which might cause C-states to be disabled. * Affected hardware: Lenovo X201 Tablet * Affected OS: All ---------------------------------------- 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. -- You have received this notification because you have either subscribed to it, or are involved in it.
