I'm happy to try and help, but I'm not too familiar with coreboots code. So I'll try my best. There's not too many logs I can really attach. The mute button still works like I said, but the LED just doesn't turn on/off. Could you please let me know where the code would be for this so I can start analyzing it? For Thinkfan, I get the following error: ``` ERROR: ~TpFanDriver: Resetting fan control in /proc/acpi/ibm/fan: No such file or directory ERROR: ~TpFanDriver: Resetting fan control in /proc/acpi/ibm/fan: No such file or directory ERROR: init: Initializing fan control in /proc/acpi/ibm/fan: No such file or directory ``` I couldn't run board_status because I got: ``` Getting coreboot boot log Getting timestamp data Verifying that nvramtool is available Getting all CMOS values Failed to run "util/nvramtool/nvramtool -a", aborting ``` Thanks ---------------------------------------- Bug #533: T440p audio mute button and fan control not working https://ticket.coreboot.org/issues/533#change-1774 * Author: frantic from xboot * Status: New * Priority: Normal * Target version: master * Start date: 2024-03-07 * Affected versions: master * Affected hardware: Lenovo Thinkpad T440p * Affected OS: All Linux distributions ---------------------------------------- In recent coreboot versions, the audio mute button and fan control has stopped working. Whereas you use the same revision from Libreboot, it all works fine and smoothly. This leads me to suspect that someone changed someone without testing, which is real annoying. The audio mute button technically still functions, but the LED no longer turns on/off. Always just off. Fan control no longer works with Thinkfan. /proc/acpi/ibm/fan doesn't exist any more. I've tried "force loading" thinkpad_acpi, but it doesn't work. -- You have received this notification because you have either subscribed to it, or are involved in it.
