Hi there, I'm using a Lenovo Thinkpad L530 with Linux Mint 14 and a 3.5.0-37-generic Kernel that uses the thinkpad drivers. When plugging in or plugging out my external power source, there appears the following message in the Kernel Ring Buffer: [ 2148.317725] thinkpad_acpi: unknown possible thermal alarm or keyboard event received [ 2148.317732] thinkpad_acpi: unhandled HKEY event 0x6040 [ 2148.317735] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx If you have more questions about my setup, please feel free to ask.
