Abstract

A method and system for controlling computer operation time is provided for counting how long the time for using the computer lasts. The steps of the time counting method are as following. First step is counting an operation time period for using the computer at the computer powered on; second step is determining the operation time period equal to a predetermined operating-time limit; third step is controlling the computer into an interrupted operating state when the operation time period is equal to the predetermined operating-time limit, wherein an interrupted time period for the computer stayed in the interrupted operating state is counted; fourth step is determining the interrupted time period equal to a predetermined suspension time; and fifth step is controlling the computer back to a normal operating state when the interrupted time period is equal to the predetermined suspension time, wherein the operation time period is re-counted.

wherein in the step of starting to count operation time period of the computer, the device drives the computer to execute a program for counting computer operation time for counting the operation time period of the computer.

11. The method according to claim 1, further comprising following steps:

determining whether the operating time of the computer is in a predetermined suspension time or not; and

setting the computer into the interrupted operating state if the operating time of the computer is in the predetermined suspension time.

12. A method for controlling an operation time of a computer comprising the steps of:

as the computer is powered on, determining whether the starting time of the computer is in a predetermined operation time or not;

if the starting time is not in the predetermined operation time, setting the computer into its normal operating state and starting to count an operation time period of the computer;

comparing the operation time period equal with a predetermined operating-time limit;

setting the computer into an interrupted operating state when the operation time period is equal to the predetermined operating-time limit, and starting to count an interrupted time period for the duration of the computer staying in the interrupted operating state;

comparing the interrupted time period with a predetermined suspension time; and

restoring the computer back to its normal operating state when the interrupted time period is equal to the predetermined suspension time, and initializing the operation time period of the computer.

13. The method according to claim 12, wherein if the starting time of the computer is in the predetermined suspension time as the computer is powered on, the computer is set into the interrupted operating state, and the computer is restored back to its normal operating state when the preset interval ends.

14. The method according to claim 12, further comprising following steps:

comparing the operating time of the computer with the predetermined suspension time;

if the operating time of the computer is in the predetermined suspension time, setting the computer into the interrupted operating state; and

restoring the computer back to its normal operating state when the predetermined suspension time ends, and initializing the operation time period of the computer.

15. The method according to claim 12, wherein the computer comprises an operating system (OS) installed thereinside and at least one peripheral connected thereon, wherein an interrupt request (IRQ) transmitted from the peripheral to the operating system is masked via a mask when the computer is set in the interrupted operating state.
