Logitech M305 was working properly for close to 10 years. suddenly the scroll wheel only scrolls up a few lines before stopping. I scroll down the page without issue, but when I reverse to scroll up it only goes a few lines. Have been searching solutions proposed in "similar questions" to no avail. Switching on natural scrolling appears to make it worse.

  • Buy a new mouse. 10 years is enough. – Pilot6 Oct 04 '20 at 16:50
  • Just tried another logitech mouse from another system and it works. But is changing the hardware really a solution for our problems? – randy mentor Oct 04 '20 at 16:54
  • Yes, it is not a software problem. The mouse is broken. – Pilot6 Oct 04 '20 at 16:55
  • Wait wait wait; hold on. Did/Does the mouse work on other devices? (Windows, other Linux systems, etc?) If that's the case the mouse is not broken. Although, I can't disagree 10 years+ is considered, old. But are we really sure the mouse is broken? Edit: does the (I don't know what they are called) 'left-right scroll-clicks' (That is used to repeatedly scroll) ? – William Martens Oct 04 '20 at 17:01
  • It's a bad mouse. Probably dirt in it. Squirt just a little WD-40 in around both sides of the mouse wheel, move the wheel both directions for a bit, retry on computer. Report back. Start comments to me with @heynnema or I'll miss them. – heynnema Oct 04 '20 at 17:58

First unplug the mouse. In the battery compartment there are probably a couple of screws, open the case. Then blow out the wheel sensor with air (by mouth or canned air, etc.).

A few drops of isopropyl (rubbing) alcohol in the wheel sensor can clean it out nicely, the alcohol will evaporate quickly.

If it is a wireless USB mouse try connecting the dongle with a USB extension and put it where the signal is not blocked by the computer case, I tried this on a problem mouse and it improved performance.

  • Don't know why I didn't think of this myself. Wow. The dust was so packed in there! Funny thing is I've done this mouse clean-up before. Senior moment, perhaps. Thanks @b-fife – randy mentor Oct 06 '20 at 01:10
