(i.e. toggling Fn lock) In fact, the WMI 0xd0 event is already handled by ideapad driver in the ideapad_wmi_notify function. The only appa= rent difference between pressing "open app" and pressing Fn + ESC is that the la= tter also toggles the LED on the ESC key. This might be a firmware issue however= , as this key does nothing in Windows either. Thanks a lot for your support! --=20 You may reply to this email to add a comment.
