I use a laptop in the car. It has it's own battery, and I want the carputer to remain on for absout 10 minutes before going to standby (an hibernate after one houer).
This is working fine until I start map monkey or freedrive. When one of them are active, the standby is working every once and a while, and not when it is supposed to.

Is this a bug or a feature? Is there anything I can do about it?

If i press start-shut down-standby , the computer goes to standby without any problem.
