Sorry you completely lost me on your problem as well as on the solution you asked for. Anyway CSSU-T shouldn't have touched indicator LED behavior. Probably your problem is unrelated, whatever it is. On a sidenote: LED pattern editor is prone to erroneous behavior caused by 'unusual' user actions. Particularly you have to click "test" again to stop it, before closing LED pattern editor. If any unclear problems, I suggest to restore /etc/mce/mce.ini to default/original. /j
