Built in mouse won't function

Anytime a device, (keyboard, mouse, USB device) stops working, the very first point of issue is to re-install the drivers. Drivers have been known to inexplicably become corrupt and will malfunction or not function at all. In case such as yours, where the device is built into the hardware itself, it's best to go to Start>Computer, right click Computer, click on Properties, then click on Device Manager. Find the device that is malfunctioning, in your case, the mousepad, and right click on it...then click uninstall. Reboot your system and it will reload the drivers on restart. Nine times out of ten, this will resolve the problem. There is a slim possibility that your mouspad plug has become loose...if that's the case, you will have to remove the keyboard and reseat the plug. Youtube has tons of videos showing how to do this with various laptops.

I presume you can see the motion sensing red LED or laser beam shining under the mouse. If not, that has gone bad, and it would probably be more economical to replace the mouse than to attempt a repair.

If the light is on under the mouse, try cleaning the lenses (both LED and photoreceptor) with a cotton swab dampened with isopropyl alcohol (rubbing alcohol). Don't scrub, just wipe the optics gently until clean.

Desktop or Laptop ?What type of mouse ??...
Enable a Mouse for a Laptop
Without the ability to drag and drop and point and click, a laptop computer is merely a desk ornament.
Most laptops are manufactured with a built-in mouse in the form of a touchpad.
If the touchpad fails or if you just prefer working with a mouse, it is easy to enable a mouse for use with your laptop.

Purchase a mouse that is compatible with your laptop.
You can find compatibility information on the manufacturer's website.
If the mouse is wireless, make sure that the USB receiver is included, or purchase it separately. The mouse will not function without the receiver.
Insert the batteries in the mouse if you are installing a wireless mouse.
The battery compartment is generally located on the bottom of the mouse.


Connect the USB mouse to the USB port on the computer.
If you are using a wireless mouse, connect the USB wireless receiver to the USB port.

Turn the computer off and then on again if you are enabling a standard mouse with a wire.
This will instruct the computer to run the "new hardware" wizard, which will walk you through the installation of the mouse, and your mouse will be enabled.

Turn the wireless mouse over, and locate a small indentation with a button.
You may need to use the tip of a pencil or pen to depress this button.
Simultaneously press the button on the mouse and the small button on the USB receiver.
This will initiate communication between the mouse and the receiver.
Hold the buttons down for about 5 to 10 seconds until the light on the mouse comes on.

Test the connection by moving the mouse.
If the cursor moves, you have successfully enabled the mouse.
If not, check that you have the batteries installed.
Try pressing the buttons independently of one another.
Press the button on the receiver until the light blinks and release it.
Press the button on the bottom of the mouse until the light on the mouse is lit.
This should enable your wireless mouse.

Wireless Mouse to Your Computer & Laptop
Connecting a wireless mouse to your computer is a great way to reduce clutter around your workplace. Also, it is an alternative to using your laptop's directional pad.
Wireless mice work just as well as wired mice for most computing needs.
The only detail that wireless mice lack compared to wired mice is the DPI (dots per inch) and the frequency rate, which is essential to the "fast twitch" movements in gaming.
However, most people do not need highly responsive mice; therefore, wireless mice are perfect for any other computing activity other than gaming.

Insert batteries into your mouse. If your mouse is rechargeable, charge it in the docking station provided with the mouse.
Buy a wireless adapter that works with your mouse.
If your laptop is enabled with wireless technology or Bluetooth, skip to the next step.
Install the drivers for your mouse.
Reboot the computer to apply the changes.
Power on the mouse and let the computer recognize the new hardware.
If you are using a mouse that requires software to run, enable the mouse in the software that is provided to you.

When working with wireless it is possible something maybe interferring with the signal for the button click function as well. Hope this helps.
