  • Wiggle the USB cord free of the mouse.

  • Resist the temptation to yank the cord free. The wires are very delicate and soldered connections are weak

  • Remove one 3mm Phillips #1 screw.

  • The quantity and location of screws holding the board to the mouse depends on the manufacture date of this mouse. All screws should be easy to find.

  • Push the broken axle piece out of the socket.

  • Glue broken axle piece back onto the scroll wheel.

  • This repair will last only as long as your glue or epoxy holds. The axle will re-break with weak glue and heavy use. My axle survived several heavy use days, just long enough for Monoprice to send me a new mouse.
