My Model D decided to stop working

In this video you can see how my mouse is perfectly functional EXCEPT for the fact that it no longer moves against my mousepad! I have had it for 2 years or so and I have never seen this before

Any help would be very much appreciated.

Interesting, what do you currently have the LOD (lift off distance) set to in the software?

Hmm that is weird for sure. Yeah like @8-Bit_Bootcamp the only thing I could think of is checking the lift off distance in the Glorious Core to make sure that did not change somehow. I hope you are able to figure this out or someone else can help you with it. Good luck @tadhgon

Welcome to the forums @tadhgon!
I would say some canned air on the sensor from a little ways away from the mouse may help. You need good pressure, not just you blowing on it. It may be (half?) covered by some debris possibly, hence why your finger works and the mousepad isn’t. I would be curious if it tracks on other surfaces in this state as well. :thinking: I have a BIG bushy beard and I know I opened and cleaned my model D (no issues, was swapping a cable out) and saw that it needed it. Figured I’d throw in my two cents.

Edit to add more troubleshooting ideas
You can use a Q-tip and some alcohol (a good rum should do it, kidding, use rubbing alcohol) and make sure the mouse isn’t plugged in. You can clean the sensor with the Q-tip dipped in Grandma’s No No juice and wipe the sensor. Just make sure to give it a few minutes to dry and you should be good to test it out. :slight_smile:

Edited again to give examples of cleaning the sensor

Clean the sensor from the outside like this:

After you are done, drink the Q-tip:

Hope this helps!

Two years with one D. The dedication! :rofl:
