@Rex, I haven’t done it yet (I’d quite like to enjoy it for a while before I screw it up 😉 ), but you apparently do have to unscrew the lot: > [@Mouse ball got stuck in 1 direction, cleaning was not convenient](https://forum.clockworkpi.com/t/mouse-ball-got-stuck-in-1-direction-cleaning-was-not-convenient/8841): > > I had a situation that the mouse ball worked in 3 directions: left, right, down, but not up. When moving finger up, the ball did not rotate under finger. So I could only use external mouse. I wanted to fix this. First I had to open the deveterm and take out the keyboard. Then unscrew all 23 (if I counted correctly) screws on the keyboard. To remove the PCB. Then the mechanical part of the mouse device was finally free. I took it out. Top plastic part and bottom plastic part held together… When I do so I intend to take photos and post them here for posterity.
