ThinkPad L13 Gen 2 AMD (21AB): Caps Lock LED broken by ACPI GPIO 11 interrupt conflict
2026-10-15 18:25 UTC
Hello, I'm reporting a Caps Lock LED issue on my Lenovo ThinkPad L13 Gen 2 AMD running Arch Linux. I found a workaround that completely fixes it, and I hope the findings might help implement a permanent kernel fix. **A quick note:** This is my first time using Linux, and I'm a complete beginner when it comes to kernel development. I used ChatGPT (GPT-6) to guide the troubleshooting process, analyse my laptop's ACPI firmware, and interpret the results. I personally ran the diagnostic commands and verified the observed behaviour, but the technical explanation below is AI-assisted. Please correct me if any of the analysis is inaccurate. ## Problem Under Linux, the physical Caps Lock indicator LED never illuminates, even though the Caps Lock key itself works normally. The LED works correctly under Windows and during certain stages of boot, so the hardware itself is functional. After investigating, GPT-6 identified what appears to be a conflict involving GPIO 11 on the AMD AMDI0
