Mouse Balls ! How to clean a cranky mouse

This applies to ball type mice not the optical type.

If your mouse has stopped moving the cursor but the buttons still work or it isn;t as smooth as it used to be then this tip should help fix that. A lot of people will go out and buy a new mouse when all they needed to do was clean it.

To clean your mouse all you need is some rubbing alcohol, paper towels, cotton swabs and sometimes a pair of tweezers.

First thing to do is open the cover on the bottom and take the ball out. Use your thumbs to twist the cover and it will unlock. Set these aside we will clean them last.



Now look in the cavity and you will see a couple of wide rollers. These are what the ball rubs against and these in turn are used to generate the position signals to your computer. When they get dirty they won't roll and the result is that the mouse doesn't think it has moved. When you look at the rollers a dirty one looks like the photo.


The grey can be a a few things usually a mix of oils and dust. And sometimes it is lint. Soak one of the swabs in alcohol and wipe the roller. You will have to clean a spot then rotate the roller to clean a new area. When the stripe or buildup is gone then go to the next one. This takes a minute or so per roller so it is quick. If the buildup is stubborn you may need to scrape it off then clean.

The next thing to clean is the ball using a paper towel with alcohol. Just give it a good wipe and let it dry. Next clean the cover and the bottom of the mouse body. You may want to clean the surface you use the mouse on as well.

Replace the ball, replace and lock the cover in place and you are done.

The mouse should work normally now. If it still doesn;t it can be due to wear or lint on the internal sensors. However cleaning the mouse like this fixes it about 99.99% of the time.

sir, i want to know about the optical mouse in detail. what is the important point of it to use. thanks, tin


Hi,
Optical mouse was developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor.
The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.
Optical mice have several benefits over wheeled mice:
No moving parts means less wear and a lower chance of failure.
There's no way for dirt to get inside the mouse and interfere with the tracking sensors.

Increased tracking resolution means smoother response.
They don't require a special surface, such as a mouse pad.

Although LED-based optical mice are fairly recent, another type of optical mouse has been around for over a decade. The original optical-mouse technology bounced a focused beam of light off a highly-reflective mouse pad onto a sensor. The mouse pad had a grid of dark lines. Each time the mouse was moved, the beam of light was interrupted by the grid. Whenever the light was interrupted, the sensor sent a signal to the computer and the cursor moved a corresponding amount. This kind of optical mouse was difficult to use, requiring that you hold it at precisely the right angle to ensure that the light beam and sensor aligned. Also, damage to or loss of the mouse pad rendered the mouse useless until a replacement pad was purchased. Today's LED-based optical mice are far more user-friendly and reliable.

Thanks and regards,

mouse started a shakey cursor, how to fix?


If it's an optical mouse (without a ball), try using it on a smooth surface, such as a sheet of copier paper. If the cursor is jumping around even when the mouse is sitting still on your desk, junk it and get another. With optical mice sometimes selling for as little at $2, it isn't worth repairing them.

Logitech Marble Mouse became erratic then stopped


Nope have to throw it away and buy another. I've had this same problem every 3-4 months: works fine then it disappears from device manager then it works again at random. I end up replacing it after my curser stops moving for minutes at a time. After a few months the replacement does the same thing. My 5th replacement will be Kensington, Logitech apparently sucks

Mouse stopped working, but appears ok, batteries ok, can't determine problem


Is the batteries good. If so try,

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud

Hope this helps others. My mouse stopped controlling cursor but buttons worked. Problem was it would not work on a black table. Slip a piece of white paper under it and waaala! It works. I'm thinking optical mouse and dark surface might be an issue.
