Some items require that it be returned in original box if something goes wrong with it. I know this is what is required for my laptop. I know that it used to be that way with TV's. I helped a friend clean out her father's house after passing and he had every box for every electronic that he owned! Some he didn't even have the item anymore. Check your warranty for your machine and/or send an email to the manufacturer asking if the box is needed for returns.
