I have two identical laptop Toshiba R30-COne is running Win 10 - 1803, no issueOne is running Win 10 - 1909, touchpad cannot control coursorIssue definitely not related to Fn + F9.Issue seemed related to driver handling on new Win 10 update.With the Win 10 - 1909 laptop, when no external mouse connected, device manager showed two devices under 'Mice and other pointing devices'1. HID-complaint mouse2. Synaptics PS/2 Port TouchPadwhereas the Win 10 - 1803 laptop only showed Synaptics PS/2 Port TouchPadTouchpad software can sense the touching, page scrolling using two fingers worked, just cannot move cursor.Uninstall device driver and reinstalling will work after laptop's first restart.Issue will re-appear after next computer restart. Using external mouse is the only workaround for now.I swapped hard drive on the two computers, symptom swapped on them, too!By the way, anyone care to share where to download Win 10 - 1803 ISO, please?Thank you.:).
