Components: Mouse

A user reports that his mechanical mouse is moving sporadically. You attempt to clean the ball, but the mouse still behaves erratically.
What should you try next?
1. Verify that the mouse is connected to the correct port.
2. >>Clean the rollers using rubbing alcohol and a cotton swab.
3. Install a new driver.
4. Change the battery.
Explanation : A mechanical mouse uses a ball that activates rollers when it is moved across a smooth surface. Both the ball and the rollers can gather dust and other debris from the environment. One of the symptoms of a dirty mouse is that the mouse pointer seems temporarily stuck or moves sporadically.

You do not need to change the battery. A mechanical mouse does not have a battery.
When a mechanical mouse moves erratically, the problem is due to a dirty ball and rollers. Installing a new driver will not correct that problem.

The mouse is not corrected to the wrong port. If the mouse were connected to the keyboard port, it would cause other symptoms, such as random characters appearing on the screen or the computer would beep at startup to indicate that a keyboard was not attached to the keyboard port. It would not function as a mouse, even erratically.
