My mouse stopped working due to ware n tare. so i took out the section of wire that was bent and messed up, reqired everything and electrical taped it all back together. BTW, this was all after i couldnt figure out how to open up the mouse and ripped it open before finding the screw. now the mouse works, left click, right click, middle click. but as i use the scroller, each notch turns it off, then a notch further turns if back on. turn a notch and mouse stops working, laser light blinks quickly, and device manager no longer reads any device connected, turn the notch again, everything is back to normal.
