Introduction

If the mouse wheel spins freely, the sensor inside the mouse cannot detect the wheel accurately. Inaccurate detection of the mouse wheel will cause screens or web pages to move up and down randomly. This repair guide will help you take the mouse apart and push the spring back to its correct position. You are not required to have any repair experience. You should not encounter any damage to both yourself or the mouse if you follow the steps in this repair guide.

Step 5

  • Use the 2mm flat head to lift up the spring leg.
  • Use the screwdriver as a lever to pry the spring leg back into the scroll wheel
  • You may need to use your thumb to pull the scroll wheel to the left a few millimeters, creating enough of a gap on the right side for the spring leg to fit into the mouse wheel cavity.
  • The spring leg should no longer be visible once aligned inside the mouse wheel cavity.

Step 6

  • Before reassembling the mouse, confirm if the scroll wheel is fixed appropriately.
  • Gently place the mouse down on the table and scroll the wheel. There should now be a noticeable difference in resistance, and it should no longer freely spin.
  • If the scroll wheel is still not fixed, you may need to readjust the spring into the cavity again (see Step 5).

Great tutorial. I thought I needed to buy another one. With this I managed to fix it under 2 minutes. Thanks! :)

Excellent instructions, I searched the web for days looking for the solution. I could not determine if it was software or hardware, the mouse wheel has always spun free, no clicking. After following your instructions, it clicks when I scroll and the spontaneous jumping is gone. Thanks a million!

Fantastic instructions! I was struggling to find out how the spring should be placed for the proper ratcheting behavior. This walk-through got me there in less than a minute. Thank you very much!

Is there any way to replace the spring if lost?
