Bug #448
Updated by Karsten Schnier about 1 year ago
Hello, I have been having some issues with TLP on my corebooted T440p. I am running artix linux with grub on top of coreboot (self compiled libreboot). I have had issues with the ACPI battery readings. Coreboot does not provide power readings, but instead only current readings. More details can be found in the TLP github issue: https://github.com/linrunner/TLP/issues/657#issuecomment-1293730559. [[https://github.com/linrunner/TLP/issues/657#issuecomment-1293730559]]. This causes TLP to not recognize the thinkpad and go to default mode. Additional, it prevents recalibration of the battery even when the thinkpad battery driver is forced. Is this due to misconfiguration in the coreboot build or issues with coreboot itself? Finally, is there a method to change the /sys/class/dmi/id/product_version string? As of now coreboot only reports "1.0". This prevents some methods of board identification from working. Thank you!
