I recently got a wireless mouse. It worked fine till the battery died. I changed the battery and now it dosnt work. The light comes on and everything but it wont move.

The connection may possibly be bad or your mouse sadly may be defective. If you have a wired mouse nearby, try using the wired one.

. . . never mind. . . I'm an idiot. I just had to push connect on the wireless recever thing.

I thought it wouldn't be connected. I've done the same before, so don't think it never has happened to anyone else. ^_^
