I installed zorin OS on my pc on dual boot with windows. Whenever I connect my wireless keyboard (it has USB cord to connect both mouse and keyboard) the zorin OS freezes. I updated kernel and drivers but still it didn't work. I'm facing this issue only on connecting the keyboard and mouse. However the Os works smooth with keypad and keyboard (inbuilt laptop). And also zorin is draining the battery highly. I don't have any problem with windows it works fine and fast, while zorin lags a lot in case of opening apps also.
