Wireless presenter dont work

Did you press the right button on the remote? To 'sync' the sender and reciever, and thus start it working, you've got to turn the handheld OVER and press the mysterious little button in the middle at the same time as the button on the USB stick. Also helps if you have them right next to each other when you do this. You should see a green light on the USB stick, and the laser pointer should work on the handpiece if the batteries are good. Mine was working fine for heaps of presentations then suddenly stopped one day and only the laser pointer would work. Batteries were fine, as is the common story. Then I found out that if you turn the presenter over and press the 'reset' button in the middle simultaneously with the USB reciever stick, the two 'sync' and it starts working again, hey presto. I've always found it a breeze to use once I figured this out. If that doesn't work take it back, you need a new one.

Just bought one too.. At first I was shocked as nothing was working, except for the laser. Microsoft has NO info! I did some research online, and found that I had to press some sort of button, which I could not lockate on the reciever.. Nor did I see any green light. Yet, I was aware of some sort of piece of plastic resembling a button at the back of the receiver.. I made the sigh of the cross and opened up teh receiver.. The first thing that fell was a tiny Surface-mount switch. I plugged the receiver back in the USB port (receiver being without casing) and temorarily mounted the switch in place, and pressed the switch.
I finally saw the green light!! See, that was the problem. Working perfectly. Now I need to just solder teh switch back 2 place.
