Hibernate mode uses the hiberfil.sys file to store the current state (memory) of the PC on the hard drive and the file is used when Windows is turned back on. In Hibernate mode the PC power is down entirely, so you can even take the battery out, put it back in, and be right back where you were. hiberfil.sys is a hidden file. It means that you could see it in windows file manager only if you checked 'Show hidden files and folders' in Folder Options.
