I have a kensington wireless mouse. the wireless keyboard works, but the mouse does not. The red laser light is on, but it won't move

You can contact Kensington's customer service and see whether they will ship you a replacement. As an alternative, you could buy another Kensington Wireless Pilot Board mouse and use its receiver. As a third alternative, you could buy another Kensington wireless mouse or keyboard and see whether the receiver for that will pick up the Pilot Board keyboard. Finally, you could buy another wireless mouse or keyboard (not Bluetooth) and see whether its receiver will pick up the Pilot Board.

If the power cells are new, both the keyboard and mouse are powered correctly (Battery I assume are positioned correctly). If Neither one operates, then check the small dongle that fits into the USB port. It may have been loosened, and if so just pull it from the port and reinsert it in another port. If still no connection, then the dongle may have burned out. The problem: Once a dongle is spent, the entire set is useless as they operated on an audio signal (Frequency) set for that mouse/keyboard. No replacements.

your mouse laser is damaged. please replace your mouse.

Make sure that the switch on the mouse is ON. Try another battery. If you get the same problem, you need to contact the manufacturer or the reseller for RMA.

Kensington wireless mouse is compatible with this system:

PC-Windows® 98, Me, 2000, or XP with USB port
USB Macintosh® with OS 10.1.5 or later
USB Macintosh® with OS 8 and 9 device will only function as a 1-button mouse

If you buy this item you have a disk utility on it and provide the software to run on the system. If not you can download it at this site: http://us.kensington.com/html/4398.html

Check underneath for dirt or debris blocking the laser light lens, try on a different surface ie (mousepad). If that doesn't solve your problem, it's time for a new one.

I unplugged the usb connector and took out the batteries for both the keyboard and mouse for 30 seconds. Then I plugged everything back in.

Normal 0 Assuming that you have good batteries installed, turn the Keyboard over and locate the small reset/connect button on the back of the keyboard and press it. Then try to see if it is working. If not try pressing the button on the receiver and then on the keyboard. Try typing, should work okay.
Hope this helps. Bud

Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud
