Is it possible to control ThinkPad LEDs? The driver acpi_ibm(4) is supposed to provide (some of) such functionality. Under /dev/led I have: ahci0.0.fault ahci0.0.locate ahci0.1.fault ahci0.1.locate ahci0.4.fault ahci0.4.locate em0 thinklight I have no idea about AHCI stuff (and don't really care of it). "em0' is the network connector LED. I can echo 0 or 1 or output of morse to it and it works. "thinklight" works somehow strangely (this is keyboard backlight and overhead light), although some people report it's working properly. However there are no other LEDs, e.g. power button, speaker, mic, sleep indicator, battery. Does anybody know whether it's possible to enable control of them? Thanks for advices, Sergey
