Then it's not very clear if it will last an hour. All of a sudden the issue becomes system specific, or it may even depend on things like whether wake-on-lan is enabled, right? If we could get a power management event and wake the system when the battery reaches a low condition that would be really awesome. But I don't think this is possible AFAIK. Thanks, Adam
