I know the MBP will auto-hibernate when it is on a low battery. However there are time when I don't use the MPB and I thought it might be handy to put it into hibernation even when the battery is topped up, but I won't use it for a day or two. I recently slapped on Windows 7 on a Dell Mini 9 and I'm finding hibernation as opposed to sleep handy. Am I missing something on the MBP regarding hibernation? Is there a utility that would work here?
