Title: Computer having saving function by keylock operation
Inventor: PARK JONG HYON
IPC: G06F1/32
Filed: 1998-12-01
Abstract: PURPOSE: A computer having saving function by keylock operation is provided to minimize a power consumption of a computer in a keylock state by performing a saving function or a function for turning off a display according to a keylock operation. CONSTITUTION: A keylock switch(200) generates a keylock locking signal and a keylock releasing signal by an operation of a user. A power manager(210) generates a system management interrupt(SMI) according to the keylock locking signal generated by the keylock switch(200) so that a CPU and a system logic circuit(230) convert a system state into a suspension mode. The power manager(210) receives a power managing command from a SMI processing unit and transmits a power supply control signal to a power supplier(215). The power manager(210) generates a keylock locking control signal and transmits the generated keylock locking control signal to an input and output controller(220). The input and output controller(220) disregards an input signal from an input device having a keyboard(222) and a mouse(224) by the keylock locking control signal transmitted from the power manager(210). The input and output controller(220) receives a keylock releasing control signal from the power manager(210) and normally processes the input signal from the input device to generate an input and output interrupt.
