Not sure why this is happening, I have a user that docks his laptop. When he locks his computer to go away from his desk, if he lets it sit for around 2 hours or so and comes back the mouse is no longer working and he has to reboot his laptop for it to be functional again. However, whe he is away for less than an hour the problem does not occur. Could there be any reason as to why when the laptop sits idle for an extended period of time it would not be funtional anymore?
