Do you mean that the mouse works when the laptop is connected to power
but stops about 20 seconds after power is disconnected, that
reconnecting power gets the mouse working again, and that this is a
regression introcued at some point between 2.6.32 and 3.0?

Please attach output from "reportbug --template
linux-image-$(uname -r)" so we can work on diagnosing and fixing (or
at least automatically working around) the underlying problem.

Hope that helps,
