However, the S3, S4, and S5 signals of the south bridge circuit cannot know that the computer system is in the reboot state, because when the computer system is in the reboot state, the S3, S4, and S5 signals are still at high level However, no change has been made, and since the system flag value remains unchanged during the restart process of the computer system, the system flag value of the keyboard controller will be cleared to 0 until the PCI reset signal changes from high level to low level. The actions are the same as those performed when the system is ready to enter the standby state, hibernation state, or shutdown state, so that the keyboard controller cannot judge whether the computer system executes the restart action based on this information, and thus causes many actions corresponding to the system restart It cannot be effectively implemented, and it also makes the restart time lengthy and reduces system performance

A method for judging whether a computer system carries out the motion of reboot or not comprises: judging whether a keyboard controller-PCI offset signal is switched into a low PWL from a high PWL or not; when the PCI offset signal is switched from the high PWL to the low PWL, judging whether a system value of statistical indicant is a first value or not; when the system value of statistical indicant is the first value, setting a reboot parameter as a second value and removing the system value of statistical indicant; judging whether one system state of the computer system is not in a starting state or not; deciding whether to remove the reboot parameter or not according to the judging results; judging whether the PCI offset signal is switched from the low PWL to the high PWL or not; whenthe PCI offset signal is switched from the low PWL to the high PWL, judging whether the reboot parameter is the second value or not; judging whether the computer system carries out the motion of reboot or not according to the judged result.
Description
technical field [0001] The present invention relates to a method for judging whether a computer system executes a restart action and its related computer system, in particular to a method for judging whether a computer system executes a restart action by using a keyboard controller of the computer system and related computer systems. computer system. Background technique [0002] In today's modern information society, the computer system has become one of the indispensable information tools for most people. Regardless of whether it is a desktop personal computer, a notebook personal computer or a server, etc., its operating clock is getting higher and higher, and the application level also increasingly widespread. [0003] According to the specifications formulated by the known advanced configuration and power interface (ACPI), and according to the power saving state of the computer system, the computer system can be divided into S0, S1, S2, S3, S4, and S5 states, wherein S...
