Dell sells technology such as computers, computer peripherals and consumer electronics to both consumers and businesses. Dell sells both wired and wireless keyboards and mice that are compatible with Dell and other computer systems. Dell wireless keyboards may encounter hardware, software or other problems under certain conditions.
Dell wireless keyboards transmit data to the Dell USB receiver, which in turn passes the data to the computer's operating system. The keyboard gets power from two AA batteries. As the batteries lose charge, the keyboard's transmissions can become intermittent. Replacing the old batteries with fresh ones will ensure consistent communication and resolve the power issue. b> Interference
Dell wireless keyboards operate best and are least susceptible to interference when the user places them at the recommended distance from the USB receiver. The distance, specified in the keyboard's accompanying software or installation guide, varies by keyboard. Even if the user places the keyboard at the proper distance from the USB hub, metal objects between the keyboard and hub can create interference; moving objects that create the interference resolves the issue. b> Connection
The Dell USB receiver that passes data from the keyboard to the computer requires proper and secure installation in a working USB port. If the receiver connects to the USB port improperly, or if the USB port to which the receiver is connected is faulty, the keyboard will not operate as expected. The user can reseat the receiver in the USB port, or connect to the receiver to a different, functioning USB port to resolve connection problems. b> Synchronization
Dell wireless keyboards can broadcast at more than one frequency, just as their associated USB receivers do. If the two devices broadcast at different frequencies, they will not pass information to each other. The user can resolve this situation using the buttons labeled "Connect" on the top of the receiver and the bottom of the mouse. Pressing the buttons simultaneously triggers the synchronization process. b> System
Dell wireless keyboards are compatible with most Dell systems. However, a keyboard may be incompatible with a given computer for reasons related to the computer rather than to the keyboard. To determine if this is the case, a user can connect the keyboard to a different computer. If the keyboard functions as expected with the second computer, the problem may reside in the first computer rather than in the keyboard.
