MORE INFORMATION
To troubleshoot these problems in Microsoft wireless keyboards and in wireless mouse devices, use the following methods in the order that they appear in.

Method 1: Try different ports
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 in the PS/2 port while the computer is running.

To determine whether the problem is related to the ports on the computer, use only the two cables that are included with the wireless desktop receiver, or the single cable that is included with a mouse.

USB keyboard and USB mouse
If 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
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 came 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 came with the computer.

If you have to change your configuration, shut off 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 mouse
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 2: Install fresh batteries
Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. If the problem persists, install a fresh set of batteries in the device that you are experiencing problems with.

Method 3: Resynchronize your device to the receiver
To resynchronize the mouse or keyboard to 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 other wireless keyboards and mouse more than six feet away.
 * 1) Press the button on the receiver, and then verify that the light on the receiver starts to blink.
 * 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.
 * 1) Press and release the Connect Channel button on the bottom of your mouse or keyboard.
 * 2) 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.

Method 4: Install the latest software
If you are troubleshooting a wireless mouse, download and install the latest Microsoft IntelliPoint software. For more information about IntelliPoint software, visit the following Microsoft Web site:

If you are troubleshooting a wireless keyboard, download and install the latest Microsoft IntelliType software. For more information about IntelliType software, visit the following Microsoft Web site:

Method 5: Clean the mouse lens
This problem may occur if you are using an optical or laser mouse and the lens on the mouse is dirty. To clean the lens of an optical or laser mouse, follow these steps:
 * 1) Use a dry cloth to clean the bottom surface of the mouse.
 * 2) Check to see whether the mouse functions correctly.
 * 3) If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens.
 * 4) Check to see whether the mouse functions correctly.
 * 5) If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times.
 * 6) Check to see whether the mouse functions correctly.
 * 7) If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.
