Step 10

              Fix the microswitch               
  • Lift up the wheel gently from the side shown in the pic
  • You can use this opportunity to deep clean the wheel, and the area
  • You can see the central wheel button microswitch in the second pic
  • In my case just cleaning with blowing air the switch worked! If needed you can now substitute any defective switch
  • To change the switches with new one you need the appropriate tools, and a discrete ability with soldering!!

Hello,

Thanks for this nice tutorial. I have an issue with the laser I believe. All three buttons work properly but there is no light appearing (may be this is normal if the laser beam is not in the visible range ?) and no motion al all.

I remember that this mouse never worked very well at the beginning (no fluid motion) and now there is no motion at all. The mouse is quite clean because i almost never used it, and now it seems there zero motion detected.

What should i do ?

Thank you very much! Today i fix the wheel and the dirty micro-switch. The mouse is like new again!

I love this mouse. The problem I am now having is the power. Despite opening it up, and cleaning it out, there is no power. I thought maybe something was wrong with the on/off switch, but everything seems fine there. Very sad about this situation.

This helped me today. I had lost the mouse quite a while ago. It still had batteries in it. when i found it just a few moments ago, it was corroded on the battery terminals. this guide helped me take apart the mouse to be able to easily sand off the corrosion on the battery terminals. before i put it all together i popped some batteries in and checked and it’s working perfectly. Thank you. I love this little bluetooth mouse and want it to last a long time.

Thank you for this tutorial. I recovered this mouse I had lost a while back with old batteries still inside and that had leaked. I was able to clean everything after reading this help and now I have a fully functional Bluetooth mouse again
