Wireless keyboard and mouse

This is what they call device interference, You might have to many wireless devices connected to a single USB port on your PC. Sometimes its a struggle between keyboard and mouse both wireless. Solution would be to limit the wireless devices to certain USB ports. For ex: plug the wireless keyboard to opposite USB port from the wireless mouse, vise versa. If you are using a multi-port USB connector, unplug the mouse from the multi-port and plug it to a single USB port on the PC.

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.

Laptop computers generally have built-in pointing devices such as touch pads that you can use to navigate the operating system on the go.
However, touch pads and pointing sticks are small and generally far from ergonomic.
At home, you might like to connect a full-sized mouse for greater comfort.
Computer mice connect in a variety of ways, and you should be able to find a mouse what works with whatever peripheral ports your laptop has.
As a general rule, any mouse that works with a desktop computer also works with a laptop.Laptops use the convenient touchpad and integrated scroll mouse that allow you to use just your finger to navigate Web pages, documents and open files and programs.
Just like all other hardware, the laptop's integrated touchpad and mouse can experience errors and problems that cause you to lose functionality for a length of time.
Whether the laptop's mouse is not working because of internal errors or conflicts with another device, several "tricks" can work to restore it.

Locate the function "Fn" button on your laptop in the lower left corner of the keyboard.
Look in the keyboard's upper row (the F1 through F12 buttons) for an icon of a touchpad or computer mouse.
This keyboard button acts as the toggle switch to enable and disable the built-in mouse and touchpad function.
Press and hold the "Fn" button together with the mouse icon button.
Look for the disable/enable symbol that briefly displays on your screen.
Slide your finger over the laptop's mouse and attempt to use it as normal.
Press the Windows keyboard key if using Windows 7, type "main.cpl" in the search box and press "Enter."
Press the left arrow key to navigate over to the "Device Settings" tab.
Press the tab key to reach the "Enable" button in this section.
Press "Enter" on your keyboard. Press the tab key to reach the "Disable internal pointing device" check box.
Press the space bar to remove the check mark.
Put your finger on the touchpad, and move the pointer down to the "Apply" button.
Click "Apply" to save the settings. Close the mouse "Properties" box.


Press the keyboard "Windows" logo key to open the "Start Menu."
Press the arrow keys on your keyboard to navigate to the "Shut Down" or "Turn Off Computer" menu. Press the up or down arrow key to highlight "Restart."
Press "Enter" to restart your computer and attempt to use the laptop mouse as it should normally function.

Open the "Control Panel."
Go to the "Add and Remove" or "Uninstall" programs section.
Highlight any secondary mouse devices in the list that you have installed for your laptop, such as an external USB mouse.
Select the "Uninstall" option to remove any software and settings associated with this secondary mouse.
Restart your computer and attempt to use the built-in laptop mouse as normal.
Check to see if the mouse is working properly.

Press the keyboard's "Windows" button to open the "Start Menu."
Press the keyboard's arrow keys, "Enter" button and "Tab" to navigate to and open the "Control Panel."
Go to the "Hardware and Sound" section, and press "Enter." Navigate to "Device Manager," and press "Enter" to open it.
Find "Mice and other pointing devices from the list" and open its "Properties" dialog box.
Select the "Driver" tab and choose "Update Driver."
Allow Windows to search the Internet for drivers and to update them automatically.
Restart your computer after the drivers are updated, and use your mouse as normal.

I think you have to use the combo because each has sensor. trying to use just wireless mouse on a laptop might not work because your laptop cannot read the signal from mouse. Now check if both have bluetooth as that may work.

You have to install the software that came with the wireless mouse. I have several, and some will and others won't work without the software. That is 90% what it is.

Should be the same thing. Laptop is just sending commands to laptop which is already connected to the projector.

Otherwise try contacting Logitech directly here: http://support.logitech.com/contact

Is the keyboard Bluetooth wireless? If it is and your laptop has a bluetooth reciever built in I guess that could happen.... A normal wireless keyboard will only communicate with the reciever. Does the mouse also control the laptop?

First check in laptop that your wireless mouse driver are installed proeprly.
Reinstall drivers then check.

Yes and no...
"Wireless enabled" means you do not need a separate adapter to connect to a wireless NETWORK or computer, not a peripheral device.

I assume the two connectors are PS/2- plugs - one pink, the other one green. What you need is a PS/2- -to-USB adapter that should have come with your keyboard. PS/2-in, USB-out, either with or without the cables (see picture)

There are a number of things that may be causing your problem.

The first thing I would check would be the batteries, with these units having a wireless connection if the batteries become weak they will transmit a weaker signal and thus make it harder for the unit to read. Battery life is variable depending on how often you use your keyboard and mouse, and how far away from the transmitter the keyboard and mouse sit.

Also because the units are wireless there may be interference coming from other wireless devices in your household. Some possible guilty devices maybe cordless phones, Wifi adapters, and even some remotes.

Also Have you installed the intellitype and Intellipoint software for your Mouse & Keyboard. If so you can use it to check your battery life/ signal strenth and set you mouse sensitivity and type repeat rate.

On the bottom of your keyboard & Mouse and on the top of the wireless transponder there are reset buttons. Pushing the transponder 1st and then either or both the mouse and keyboards buttons should resysnc them without the need for a reboot.

Hope this helps

It's pretty universal for them to have a way to associate the mouse and keyboard with the receiver in a way that switches the channel or code it uses.  You can use that to get working, but obviously the keyboards' RF is esentially insecure.  Therefore, one of or both of you get to pick some more secure wireless stuff at the shop for the more permanent ability to get along.  If you're in a particular kind of business, you might need to look more carefully than in another.
