Hi,
Go to the start button and click on control panel.The, click on hardware or sound options and click on "mouse". When you get to the options window click on hardware. Find the mouse that you are trying to get to work. Then click on propoerties. In the next window it should state that the device is working properly. If it shows that and still doesn't work reboot the computer. At that point It should work.

Hope this helps!!

How do I setup a wireless mouse on a desktop


To setup a wireless mouse regardless of its type, do the following:

1. Insert the USB transmitter (this could look like a mini plug or a stick) and wait for windows to complete installation.
2. Once this is successful, turn on the mouse by holding down the power button. Or insert the disc that came with the mouse and run the installer. The installer will install the device drivers and setup your mouse's configuration panel which will reside in your system tray.

Make sure that the mouse has batteries and that it is switched on for it to work. It will glow red when it is switched on.

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,

An optical mouse works based on imaging principle so we have the freedom of accessing even in a 3D way. If your Optical mouse is not moving the cursor side wise, I would suggest you to look for the exact Mouse driver and install it. Usually on a Windows XP machine they work as plug and play.

If the Driver is working fine, you must look for the Windows or OS compatibility. The WDDM compatibility can also cause this to happen.

Else you have to replace the mouse.

Good Luck.

IBM Optical Mouse doesn't work


Normal 0 Try disconnecting the Mouse Receiver from the USB port and reinstall the CD software program. When the program asks you to connect the Mouse Receiver to the USB port, do so and it should work.

Mouse stopped working


I had the same problem. I find that a multi colored mouse pad seems to solve the problem. Actually the best ive found is a wood grain or striped mouse pad.

Wireless mouse quits working after a few seconds


Did you replace the batteries? This sounds like it may be the problem. A year is a lomg time for batteries depending on how often you use the computer.
After changing the batteries, you may have to do this:
Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud
