Batch files allow MS-DOS and Microsoft Windows users to create a lists of commands to run in sequence, once the batch file has been executed. If you have trouble hibernating PC and tired of process of clicks involved in it then you can simply write a batch file to do so.
If the hiberfil.sys file on the system partition is removed, the option to hibernate is not available. A common reason for the hiberfil.sys to be deleted is from running the Disk Cleanup Tool, as explained in the Microsoft article "The hybrid sleep feature and the hibernation feature in Windows Vista may become unavailable after you use the Disk Cleanup Tool" (http://support.microsoft.com/kb/928897/en-us ).
