I read the DSDT again. Fn+F5 is the soft rfkill key. It looks fine. I guess the problem is the hard rfkill status is blocked, wifi will be blocked even the soft one is unblocked. > As I know on Thinkpad machine, the hardware switch causes killswitch = set > to hard-block, and Fn+F5 causes killswitch set to soft-block. >=20 > Ike,=20 > need your comments for Fn+F5 key and wireless hardware switch on > ideapad. How does it implement on ideapad? > - press Fn+F5: soft-block wireless killswitch? > - wireless hardware switch: hard-block wireless killswitch? Both of the answers are yes. The problem is that on ideapad s205 without acer-wmi, when ideapad-lapt= op have the hard switch event, the driver asks the status of switch and DS= DT replies blocked. In the DSDT the driver read bit of GWSS as status of hardware switch an= d I can not find out anything to update GWSS in DSDT :(
