Created attachment 62882 [details] Output of dmidecode on Ideapad S205 Function keys work fine except for the hardware on/off switch for wifi on Lenovo Ideapad S205. After booting with switch in position "on" wifi is disabled. Loading module ideapad-laptop doesn't help. There exists a workaround with module acer-wmi: One can load the module "acer_wmi". After toggling the hardware switch "rfkill list" shows "hard blocked: no" and one can use wifi. After that one can unload acer_wmi and with only ideapad_laptop loaded the wifi switch works as expected powering wifi on/off.
