Issue #642 has been updated by Janez Novak. File Kernel Logs Stock BIOS.md added
I have now flashed the stock BIOS and C states didn't change in powertop at all but it runs much cooler even with turbo boost enabled than it does with coreboot. With coreboot when idle CPU temperatures usually wouldn't drop below 60c while with stock BIOS they are at around 46c. Under light load it's also much better now, with coreboot when web browsing and having a few other applications opened it could go past 75c while now it's at around 50c. ---------------------------------------- Bug #642: x201t Turbo boost not working, CPU running hot https://ticket.coreboot.org/issues/642#change-2278 * Author: Janez Novak * Status: New * Priority: Normal * Category: chipset configuration * Target version: main * Start date: 2026-05-03 * Affected versions: main * 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.
