If your mouse is acting erratically, there are a few simple checks you can do to try to fix it.
1. If you are using an optical mechanical mouse (it will have a little red light from the bottom), likely the mouse is dirty. Use a soft, clean cloth to clean the underside of it. If you are still using a mouse with a roller ball on the bottom – take the ball out. Use a soft, clean cloth to clean it, and place the ball back in the mouse.
2. If you are using a wired mouse, check the connection to the computer tower. If you are using a wireless mouse, try changing the batteries.
3. If you are using a wireless mouse, check that the mouse is turned on – there should be a little “off-on” switch on the bottom of the mouse.
4. If you are using a laptop, check that the “dongle” (the little piece that plugs into the laptop) is firmly connected to the laptop.
5. If you are using a wired mouse (or a “dongle” mouse with a laptop), try connecting the mouse to another computer or laptop.
If all of these checks are done, and your mouse is still behaving erratically – it’s time to call the exterminator (sorry, had to slip that in) and get a new mouse.
