The other thing has been suggested by DCiAdmin. The tips below may help in case of interference.To resynchronize the mouse or the keyboard with the receiver, follow these steps.
Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put any other wireless keyboards and mouse at least 6 feet away.
- Press the button on the receiver, and then verify that the light on the receiver starts to blink.
Note Some newer Microsoft devices are permanently bound to their receiver and cannot be reset. If your device does not have a button, skip to Method 2.
- If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step.
- Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
- Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.
- For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.
Another thought is that the micro switches in the mouse may be failing. We use the left mouse button most often so it wears out first. If you can click the right mouse button and it responds properly than you have an indication that your mouse is failing. One final thought is to make sure the receiver is firmly plugged in. You may also consider plugging the receiver into another port to see if the problem persists.Items such as wireless routers, radios, cell phones, desktop fans, fluorescent lights, and large metal objects like computer cases and metal furniture may interfere with the signal of the keyboard. Try to keep such items away from the keyboard, and check the behavior of the keyboard.
Do not put the mouse or the receiver near any electrical devices, especially transmitters such as cordless or cellular telephones or other wireless mouse devices or receivers. A distance of at least 8 to 12 inches is recommended. Do not put the mouse or the receiver on metallic surfaces or objects, especially long metallic rails or cables. We recommend that you keep the mouse and the keyboard a minimum of 3 feet from metallic objects.
