Abstract

A method of using alpha-photographic mode to display wake-up event of computer system (CS) includes storing a state value of energy-saving mode into the first address when CS is to be entered to an energy-saving mode, obtaining a state value of wake-up event and storing obtained value to the second address when wake-up event is detected by CS, commanding CS to execute a resident program to fetch state values in two said addresses when CS is recovered from energy-saving mode to original operation state, displaying an alpha-photographic information corresponding to energy- saving mode and said wake-up event according said state values.

Description

The method that shows the wake events of computer system with graphics context mode

Technical field

The invention relates to that a kind of the demonstration with graphics context mode is meant a kind of method that the system state and the wake events of computer system are shown with the graph text information that is easy to be understood especially at the method for the wake events of computer system.

Background technology

Consult shown in Figure 1, it is the work flow of existing a kind of computer system, shown in step 10, computer system is under working order, can judge simultaneously whether its peripheral device is operated or uses, if when not being operated for some time, in order to save power supply, as step 11～13, computing machine prepares to enter a battery saving mode, and it starts the wake events detecting function, and through BIOS or operating system, some peripheral device that will not be used or operate, for example hard disk, display, keyboard, mouse ... the power supply temporary close that waits make CPU enter this battery saving mode.Wherein, according to the behaviour in service of peripheral device, battery saving mode can be sleep pattern (i.e. the S1 state of what is called), suspend the random memory pattern (i.e. the S3 state of what is called) that writes back, time-out writes back hard disk mode (i.e. the S4 state of what is called) or shutdown mode (i.e. the S5 state of what is called) one of them.And this wake events means the system event that any peripheral device of computer system is produced when being triggered (for example keyboard is pressed, mouse is moved etc.), and these wake events are to be set in the System on Chip/SoC (chipset) of computing machine by BIOS earlier, then, as step 14, the generation of a wake events (wakeup event) can be waited for and detect to System on Chip/SoC.Then, shown in

step

15 and 16, when System on Chip/SoC detects a wake events, System on Chip/SoC will trigger computer system and be returned to original duty by battery saving mode and a state value of this wake events is temporarily stored in one of system chipset system state buffer (figure does not show), then, as step 17, carry out BIOS and make the state value that reads in this system state buffer, with inspection is that wake events is triggered, remove this system state buffer then, and, control is given back operating system as step 18, make and carry out follow-up computer operation.

And as shown in the above description,, system gets back to duty owing to building the person of putting and can't learn easily that computer system is waken up by that wake events.Therefore, known a kind of way is the test card of planting on computer main frame panel, for example POST (Power On Self Test) blocks, the diagnosis sign indicating number that comes detection system state and wake events to be produced, with the peripheral device of finding out computer system wakeup according to diagnosis sign indicating number why, to judge that this peripheral device is whether as computer system wakeup expectedly, but, owing to why diagnose yard system state that can't directly show its representative or wake events, system builds the person's of putting diagnosis sign indicating number contrast instruction card of must noting, just can learn the meaning of diagnosis sign indicating number representative, therefore, under the situation of diagnosis sign indicating number contrast instruction card not, system builds the system mistake that the person of putting promptly is difficult to cause at wake events and carries out debug.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of and shows the method for the wake events of computer system with the graph text information display system state that is easy to be understood and wake events with graphics context mode.

To achieve these goals, the present invention shows the method for the wake events of computer system with graphics context mode, its computer system can enter a battery saving mode by a duty, and when detecting a wake events, after one state value of this wake events is temporarily stored in a status register, return to described duty by this battery saving mode again.And this method comprises the steps: (a) when the preparation of this computer system enters this battery saving mode, and a state value of this battery saving mode is stored in one first address.(b) when this computer system detects this wake events, read the state value in this status register and be stored in one second address.(c) after this computer system is returned to this duty by this battery saving mode, make this computer system carry out a resident program, make the state value that reads in this first and second address, and, show a graph text information corresponding with this battery saving mode and this wake events according to these state values.

The method that shows the wake events of computer system with graphics context mode of the present invention, simple and directly perceived, and its cocoa graphics context mode that wake events and system state can be understood easily, be presented on the computer screen intuitively, make things convenient for operating personnel's deciphering, had practical value.
