Go to device manager, mice, and other pointing devices, HID Complaint mouse > Disable it. I am also facing the same issue in 5310 i5 13-inch windows 11. Problem solved after disabling HID Complaint mouse.
I have a new Inspiron 13 5310 8GB laptop and noticed the touchpad sometimes stops working for no apparent reason. I don't run many application at once so not sure why? Yet if I plug in a mouse no problems. Any ideas how to fix? Cheers
