Computer system having a screen saver with a power shutdown function and a control method thereof
First Claim
1. A computer apparatus having a screen saver program and a power shutdown function, comprising:
- a video display conveying varying visual information to a user;
a timer measuring time;
an input unit inputting signals; and
a control unit connected to said video display, said timer, and said input unit, receiving said signals from said input unit, controlling an operating system program and a screen saver program reducing degradation in said video display, starting the screen saver program when said signals are not received before a first quantity of time elapses, terminating the screen saver program when said signals are received after the starting of the screen saver program and before a second quantity of time elapses;
when a predetermined condition is not detected and said signals are not received after the starting of the screen saver program and said signals are not received before the second quantity of time elapses, said control unit automatically terminating the operating system program;
said control unit controlling a suspend program storing operating data, reducing power supplied to the computer apparatus, and enabling reconstruction of the operating data upon resumption of full power being supplied to the computer apparatus;
when said predetermined condition is detected and said signals are not received after the screen saver program is started and said signals are not received before the second quantity of time elapses and a third quantity of time elapses after the second quantity of time elapses and the operating system program is not terminated, said control unit starting the suspend program.

Abstract
This invention relates to a computer system having a screen saver with a power shutdown function and the control method thereof, comprising a timer for measuring time, an input device for inputting, and a controller for automatically terminating an operating system program when there has been no input signal from an input device for a predetermined time while a screen saver is operating. The computer system having a screen saver with a power shutdown function terminates all programs and the operating system program, such as Microsoft Windows, and then shuts down the power to a computer if there has been no input for a predetermined time while the screen saver is operating under the operating system program.

11. A method of controlling a computer apparatus having a screen saver program and a power shutdown function, comprising the steps of:
-
sensing whether a screen saver program is started; when the screen saver program is started, operating a timer measuring time; sensing whether a signal is received from an input unit before a first quantity of time elapses, the first quantity of time being measured by said timer; when a predetermined condition is not detected and said signal is not received before the first quantity of time elapses, automatically terminating an operating system program of the computer apparatus; controlling a suspend pro gram storing operating data, reducing power supplied to the computer apparatus, and enabling reconstruction of the operating data upon resumption of full power being supplied to the computer apparatus; and when said predetermined condition is detected and said signal is not received before the first quantity of time elapses and a second quantity of time elapses after the first quantity of time elapses and the operating system program of the computer apparatus is not terminated, starting the suspend program. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
