How to Identify Input Device Problems on a Windows OS Computer

When an input device like a PC mouse or keyboard stops working properly, the problem may be with the device, the computer or even the operating system. PC mouse freezes and non-responsive keyboards are only a few of the issues you may encounter, with things like driver conflicts and dirty hardware as possible culprits. Here are a few steps to help you identify and fix input device problems in your Windows-based computer.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Cotton swab
• Rubbing alcohol
• Rechargeable NiMH batteries
• Device drivers

1. Shut down the computer and unplug the device. If it is a standard PS/2 mouse, turn it over and twist the retaining ring to remove it. Clean the trackball with a damp cloth, and the roller pins inside the cavity with a cotton swab dipped in rubbing alcohol. Replace the trackball and retaining ring.

2. Replace the batteries in wireless input devices with fresh ones. Use rechargeable NiMH batteries for best results.

3. Check for bent pins or damage to the connector, then carefully plug it back in making sure it is aligned properly. Never force the connector. Reboot the computer, then test the device.

4. If it is a USB device, switch to a different USB port. Sometimes problems occur if the device is connected to a USB hub. Connect the device directly to one of the USB ports on your PC.

5. Check for conflicts in Device Manager. Click "Start" then "Run" and type "devmgmt.msc." If there are any problems, the device will have a black exclamation point on a yellow field next to it. Double-click the device icon to learn more about the specific problem.

6. Uninstall the device to correct possible driver issues. Right-click the device icon in Device Manager, then select "Uninstall." Unplug the device, then restart the computer when the operation is complete.

7. Plug the device back in, reboot the system, then allow Windows to reinstall the device drivers if prompted. If you have the original manufacturer drivers or driver disk, point the installer to that location.

Tips & Warnings

• Try using a different kind of mousepad. Some surfaces interfere with the operation of a wireless or optical mouse.
• If all else fails, test the device on a different computer. If it doesn't work, it's probably defective.
