Issue #638 has been updated by Angel Pons.
Can you please post your coreboot config file? ---------------------------------------- Bug #638: ACPI\LEN0068 (ThinkPad Extra Buttons) not detected by Windows 11 on ThinkPad T430 https://ticket.coreboot.org/issues/638#change-2260 * Author: Avraham Hollander * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2026-04-14 * Affected versions: main * Related links: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t430/downloads/ds120449-hotkey-features-integration-for-windows-10-64-bit-thinkpad * Affected hardware: ThinkPad T430 * Affected OS: Windows 11 ---------------------------------------- The device ACPI\LEN0068 (exposed as ThinkPad Extra Buttons on Linux via the thinkpad_acpi driver) is not detected at all by Windows 11. When installing the Lenovo Hotkey Features Integration driver, fn.inf shows up in Device Manager, but not bound to any device. As a result, the Fn special keys (mic mute, airplane mode, etc.) do not work under Windows 11 (25H2). On Linux, the thinkpad_acpi driver enumerates it just fine, and the buttons all work as expected. I am using Coreboot 26.03-315-gec0d1946e7f3. ---Files-------------------------------- config.txt (23.3 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
