Computer providing motion picture mode and method of setting up system-mode while playing motion pictures

A computer providing a motion picture mode, comprising:

• a random access memory (RAM) configured to temporarily store data which is processed or to be processed by the control unit;
• a storage unit configured to store motion picture data, the storage unit including a hard disk drive (HDD);
• a graphic processing unit configured to display image data of the motion picture data stored in the storage unit and processed by the control unit;
• and
• an audio outputting unit configured to output audio signals of the motion picture data stored in the storage unit and processed by the control unit;
• a control unit operatively connected to the RAM, the storage unit, the graphic processing unit and the audio outputting unit,
• wherein the control unit is configured to process the motion picture data stored in the storage unit and to control a system mode of the computer, and determine whether a condition for entering a motion picture mode has been satisfied,
• wherein the motion picture mode is a mode in which system power is supplied only to the RAM, the graphic processing unit, the audio outputting unit and the control unit, and wherein clock speeds of a central processing unit (CPU) of the control unit, the graphic processing unit and a bus of the computer are decreased when the condition has been satisfied,
• wherein, if the condition for the motion picture mode is satisfied, then the control unit stores system state information of a state before entering the motion picture mode in the RAM or the HDD, and changes the system mode to the motion picture mode,
• wherein the condition for entering the motion picture mode is satisfied with an elapse of a predetermined time after playing back motion pictures, and
• wherein the control unit resumes the state before entering the motion picture mode by resuming the supply of system power to the devices that are not needed to play motion pictures using the stored system state information when a resume event is detected during the motion picture mode.
