This is the common fault with usb keyboard and mice, on certain motherboards, as the driver has to load first on the system on boot up but tends to to load later, than the bios recognising your keyboard, making the sytem freeze as it tends to look for the keyboard first. There is no real solution to this as it is all down to what is called interupt request (IRQ). If your keyboard is set by windows as IRQ2, then it is the second peice of hardware to be started, so ideally it needs be IRQ1 to startup first. Experiment using different usb ports as one may have the IRQ1 and not cause the freeze. Sorry this is a bit technical but, theres no easy way to explain.

Step 1:
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.

Power 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.

My Logitech Wireless keyboard has lost connectivity to receiver. Wireless mouse still works, however, lights on receiver are no longer on. Just chaged batteries in keyboard.


you might have to uninstall your keyboard restart your computer then reinstall it
try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.
dust causes static which causes lots of problems with a computer and its parts
click start control panel administartion tools computer management device manager scroll to keyboards you might see a yellow exclamation or question mark or red x you will need to update driver right click to update driver
make sure the usb device is inserted correctly into the usb port (if applicable)
if your computer came with a motherboard disk the drivers could be on it
hope this helps

Keyboard does not type


If all the keys on the keyboard have stopped functioning follow the instructions below to reconnect the keyboard.

This problem is likely to be a lost connection. The connection between the mouse and the USB mini-receiver or the keyboard and the USB mini-receiver can be lost due to several reasons such as:
  • Low batteries
  • Moving the USB mini-receiver from one USB port to another
  • Moving the USB mini-receiver to another computer
  • Plugging the USB mini-receiver into a USB hub or other unsupported device such as a KVM switch (your USB mini-receiver must be plugged directly into your computer)
  • Using your cordless mouse/keyboard on metal surfaces
  • Radio frequency (RF) interference of more powerful wireless devices such as:
    • Wireless speakers
    • Computer power supplies
    • Monitors
    • Cellular telephones
    • Garage door openers
Eliminate any problem sources mentioned above that might be affecting your devices.

Follow the procedures below to reconnect your mouse and keyboard.
  1. Make sure the USB mini-receiver is directly and securely plugged into a working USB port on your computer.
  2. Make sure the mouse is turned on. The on/off indicator on the bottom of the mouse should be green. If the on/off indicator is not illuminated, press and hold the red connect button on the bottom of the mouse until the on/off indicator is green.

  3. Press and release the red connect button on the underside of the USB mini-receiver. This will broadcast a signal to your mouse. This broadcast will last only a few seconds, so you must perform the next step quickly.
    12146.1.0.jpg
    Red Connect Button
  4. Quickly press the red connect button on the bottom of the mouse for 1 second, then release it. The power indicator will flash briefly and then turn green. The mouse is now connected to the receiver.
    12145.1.0.jpg
    Red Connect Button NOTE: Holding down the red button on the mouse for more than 2 seconds may cause your mouse to turn off instead of connecting. If this occurs, start again at step number 2.
  5. Move your mouse to see if the cursor moves. If the cursor follows the mouse movements, your mouse is now connected.
  6. Press and release the red connect button on the underside of the USB mini-receiver. This will broadcast a signal to your keyboard. This broadcast will last only a few seconds, so you must perform the next step quickly.
    12146.1.0.jpg
    Red Connect Button
  7. Quickly press and release the red connect button on the underside of the keyboard.

    11399.1.0.jpg
  8. You will hear a short beep. The keyboard is now connected to the receiver.
  9. Test your keyboard to see if it is working. If the mouse now works but the keyboard still does not, see Knowledge Base article 9144.

Plz help me i want connect wire less keybroad and mouse thnksvjtawale2gmail.com


There are 4 possible ways in my awareness...
Method 1: Resynchronize your device with the receiver 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.
  1. 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.
  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.
  3. Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
  4. 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.
  5. 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.
The following example shows the buttons to push to synchronize a wireless hardware device:

USB keyboard and USB mouseIf the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer. PS/2 devices Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device into the PS/2 port while the computer is running.If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations:
  • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that was included with the computer.
  • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that was included with the computer.
If you have to change your configuration, shut down the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection. PS/2 keyboard and USB mouseIf you are using a wireless mouse with a USB connector and a PS/2 keyboard, verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer. Method 3: Reinsert the batteries or install fresh batteriesBoth the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. Remove the batteries, and then insert them again. If the problem persists, install a fresh set of batteries in the device that you are having problems with. Method 4: Check for interferenceItems 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.

I bought a logitech keyboard and mouse how do i connect to my computer and turn it on


It looks like a wireless keyboard and mouse. My Logitech keyboard and mouse have a USB 2.0 receiver, which plugs into any USB 2.0 port. Some have small USB receivers that look like memory sticks. It might be mounted on the bottom of the keyboard or the mouse. My receiver is a small box with a wire that runs to the back of the computer and plugs into the USB port. The receiver has a connect button to send a signal to the mouse and keyboard. Once they are installed you can use the button to make the mouse and keyboard recognized, by the OS.

Most likely you need to re-sync the device

  1. Resynchronizing the keyboard and/or mouse causes the devices to reconnect to the receiver using new identification numbers. Use the following steps to resync the devices:
    NOTE: The following connection sequence must be completed within 60 seconds. If the sequence is not done in 60 seconds, start over.
    1. With the receiver plugged in, press and hold the Connect button on the receiver until the activity LED flashes.
      NOTE: Some HP computers have receivers built into the front of the computer; such as TouchSmart 700 Series PCs and Digital Entertainment Centers. Look for a small connect button built into the case. If you have a TouchSmart 500 or 800 Series PC, the receiver plugs into a USB port on the underside of the case and does not have a connect button - skip this step. Figure 4: An example of a receiver c01065862.jpg 1 - Connect button and LED activity light Figure 5: Another example of a receiver c00526313.jpg 1 - Connect button 2 - Num Lock LED 3 - Alpha Lock LED 4 - Scroll Lock LED 5 - Activity LED
    2. Press and hold the recessed connect button on the underside of the keyboard until the activity light on the receiver stops flashing. When you release the button, make sure it does not stick in the depressed position.
      NOTE: If problems persist after resetting AND there is another wireless keyboard or mouse near, use these steps again, holding down the keyboard or mouse button for ten seconds. Doing so may give the keyboard or mouse a new ID number in case the other keyboard or mouse was using the same number.
    3. Press the Connect button on the receiver again until the activity light flashes.
    4. Press and hold the recessed button on the underside of the mouse until the activity light on the receiver stops flashing. Make sure the connect button does not stick in the depressed position.
  2. If your mouse and keyboard have a USB receiver, unplug the USB receiver, wait 10 seconds, and then insert into another USB port - preferably into a USB port that is closer to the mouse and keyboard. For example, if the USB receiver was plugged into a USB port on the back of the computer, unplug it and plug it into a front USB port.

Hope this helps!! Good luck!!

My wireless mouse freezes


I had a similar freezing problem with a wireless Logitech mouse and also a problem with the wireless keyboard, sometimes keystrokes would not register and sometimes they'd repeat a dozen times.
I was not able to fix the problem, so I got a Microsoft wireless mouse and keyboard, hoping it was a driver conflict that wouldn't affect both products. Wrong. The exact same thing happened to the Microsoft mouse and keyboard.
The cause of the problem turned out be that I had the receiver plugged into a USB hub along with several other devices. Moving the receiver to one of the USB ports in the back of the PC fixed the problem.
Apparently these wireless desktop devices don't like sharing USB resources with anything else.
