My computer works great until it goes to sleep. When I wake it the mouse will not work so I have to use the touchpad. If I disconnect the USB-C cable and reconnect it then mouse control comes back. However this is inconvenient because then all my open windows are moved to the laptop screen.
Computer is a Dell G5 SE and the docking station is USB-C 4K 3 Monitor
Note: My 2nd laptop a Latitude 7390 doesn’t have this issue on the same docking station. It sleeps and wakes and mouse control is fine.
