The connecting wire of the mouse to my laptop, touched a little water. (me stupid connected it straight to my laptop) Did the wire burn? or does it have a fuse in the mouse? It would be great if you could help by answering. Thank you for you’re time! Dominic Michaelides
Theres no fuse or safety chips in side the mouse and since the use dongle is wet 1- you may damaged the laptops motherboard because of shortcircuit connection( dry the port and try sth else like flash drive to see if the usb is working…or not ) 2 the mouse it self might be dead because of shortcircuit btw positive /negative and data wires. So if after drying everything and getting one of these not working ,dont panic :/ its dead and theres nothing to do about it( buy a new mouse or fix some components on laptop - if usb not working)
