Try killing acpid an # cat /proc/acpi/event then press the power button, close/open the lid, and the sleep button (Fn-F4 on mine) and see if anything appears. the standard acpi button driver should handle power and lid. in this case the thinkpad driver handles the sleep hotkey. see if things work differently when thinkpad_acpi is not included in your kernel. one difference I see is how your devices are registered with the input layer: input: Power Button (FF) as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input0 ACPI: Power Button (FF) [PWRF] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input1 ACPI: Lid Switch [LID] input: Sleep Button (CM) as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input2 ACPI: Sleep Button (CM) [SLPB] Where I see this: input: Power Button (FF) as /class/input/input0 ACPI: Power Button (FF) [PWRF] PM: Adding info for No Bus:input1 input: Lid Switch as /class/input/input1 ACPI: Lid Switch [LID] PM: Adding info for No Bus:input2 input: Sleep Button (CM) as /class/input/input2 ACPI: Sleep Button (CM) [SLPB] if you send me your .config, I'll try it out. cheers, -Len
