"Hello again Groetjes, thanks for your reply.\n \n\n\n\tYes  \"echo 'activity' | sudo tee '/sys/class/leds/helios64:blue:net/trigger'\" has an effect. The LED is now flashing blue on and off.\n \n\n\n\t \n \n\n\n\tI presume \"activity\" is the module designed for the \"System Activity LED\"  and that \"netdev\" was supposed to do a similar\n \n\n\n\tjob for the the \"LAN Activity LED\" - but no longer does. \n \n\n\n\t \n \n\n\n\tRegards ... Nick\n \n"
