I have an hp wireless mouse, and it doesn´t work!! Tried everything...

Wireless device like the mouse needs a wireless connectivity to a computer like a bluetooth or a wireless receiver. Make sure that your mouse batteries are all working and the wireless receiver is properly plug into the USB(Universal Serial Bus) port of the computer. The wireless receiver don't need battery so you don't have to worry about it. The two both have a push button, press both buttons to activate the connection. Wireless connections has limit in distance so make sure that you are not too far away from the receiver while using the mouse and that is 9 feet or 2.7 meters so keep that in mind. When the cursor moves when you move the mouse, you have connected the mouse properly. If the cursor doesn't move, try repositioning the receiver. If it still doesn't work, you may need to restart your computer (if you haven't already) or reconnect everything.

Hope this could help you a lot..:-) Thanks..

Here's what you need to do:

1. Make sure to use fresh batteries for the mouse.
2. Press the button on the receiver and then followed by pressing the connect button underneath the mouse.
3. Try connecting the receiver into another USB ports of the computer.
4. Or try connecting the receiver into another computer.

If none of these steps helps, the try holding down both connect buttons (that's on the receiver and on the mouse) at the same time for five (5) seconds and then release them.

Hope this helps and have a good day!
