My computer is an Acer notebook connected to a HDTV.

When I get up and walk away from the computer almost every time I hear the disconnect USB device sound after a few seconds.

How is this possible? There is no wires or vibration issues, and I haven't noticed any device stop working as far as external keyboard and trackball etc.

I have seen on the Internet I'm not the only one this happens to.

What's going on?

Exactly which model of Acer is it? –  techie007 Mar 9 '13 at 19:05
Do not you have any Bluetooth device with you (telephone, headset, pocket computer, GPS, barcode scanner...)? It usually has a short range of operation so it could easily disconnect when you walk away from the computer. --- Open the device manager in Windows and watch if a device does not disappear when you walk away. –  pabouk Dec 13 '13 at 10:31

I have the same issue! I have a Gateway DX4860-UR10P desktop. It's a couple feet away from me next to my desk, and when I stand up and walk away, the hard ware disconnect sound happens. I'm not accidentally pulling any cords out or even touching anything related to the computer and it will happen. Not all the time but at least half the time. Sorry it's not an answer...

I understand how how frustrating it is to not be able to comment when you so very badly want to, but please avoid posting them as answers in the future as it really goes against the principle involved. –  Roney Michael Mar 13 '13 at 3:59
