I have read the handbook and it says the Update Manager checks for updates and patches upon every boot; I quote from the handbook how often the Update Manager checks for updates: "this happens automatically whenever you boot your system."
Could the Update Manager be configured to check for updates every X minutes e.g. every 20 minutes? This would be especially helpful for those of us who use the computer for very long periods of time.

It would be
very useful for people who frequently put their computer into power saving e.g. hibernation - to avoid rebooting.
