At the back of my PC is a PS/2 socket with an image of a mouse beside it, so I presume that I can connect my mouse there. I bought an adapter with a USB socket but when I connect it all together the mouse does nothing. I know there is power at that socket and through the adapter because when I connected a wireless device there the light in it came on. Any geeks out there who can help me?
Your post is not very clear. If you are plugging the mouse into the PS2 port, you need to do this with the machine powered down. PS2 ports are not hot-pluggable.
But if your mouse is a USB mouse, it can be plugged straigh in a USB port as pinky says.
PS/2 sockets can blow. As mentioned by rojash, they aren't designed to be hot pluggable (can you believe it !!!). Unsure the lit wireless device (which I assume was a wireless mouse ?) means much (unless the wireless mouse worked).
I go along with both above posts in that if you have a USB socket free then why not take the adaptor off again and plug the mouse into USB ?
Thank you for answers so far. I would rather use a usb port but there aren't enough available. And I reiterate, why is there a PS/2 socket with a mouse image beside it if it isn't actually there to be used?
