Description

METHOD AND SYSTEM FOR PROViDiNG HYBRiD-SHUTDOWN AND FAST
STARTUP PROCESSES
CROSS REFERENCE TQ RELATED APPUCATIQNIS)
[0001] This application claims priority from U.S. Application No. 12/230, 822, filed September 5, 2008, entitled "METHOD AND SYSTEM FOR PROVIDING HYBRID- SHUTDOWN AND FAST STARTUP PROCESSES," the content of which is incorporated herein in its entirety to the extent that it is consistent with this invention and application.
BACKGROUND
[0002] Persona! computer (PC) marketing surveys show that one of the most common customer requests for a PC manufacturer is faster PC startup. Currently, most PCs are pre-loaded with Windows operating system (OS) and application software programs. Typically 1.5 to 2 minutes are needed to complete a full boot process from a Power-Off state (SS in Advanced Configuration and Power Interface (ACPI)). When an anti-virus software is running, the fuS! boot startup process may be longer.
[0003] Windows Vista currently offers the Sleep mode (S3 in ACPI), Hibernate mode (S4 in ACPI), and Hybrid-Sleep mode power management features. These power management features ailow PCs to resume quickly to the last state before power-off, each offering different power consumption level, resume time, and stability. For example, the S3 Sleep mode saves data (such as the last system state context data) in a system memory and places the system in a stand-by mode. The computer system can be woken up and used almost immediately. However, in the S3 Sleep mode, the power must not be turned off. Once out of power, the system will have to start again using a fuli boot process from the S5 Power-Off state.
[0004] The S4 Hibernate mode saves data (such as the last system state context date) in a hard disk drive as opposed to the system memory. When the computer system needs to be used again, the system boots υp using the last system state context data. Boot up from the S4 Hibernate mode takes longer than from the S3 Sleep mode.
[0005] These power management features all consume power even when the PC is not in use. In addition, with the exception of the S4 Hibernate mode, these power management features do not work if a user turns off the PC or unplugs the PC's power cord. While the S4 Hibernate mode works if a laptop power cord is unplugged, the battery power consumption of the S4 Hibernate mode is still higher than the S5 Power-Off state.
SUMMARY
[0006] A method for providing hybrid-shutdown and fast startup processes for a computer system, which includes an operating system (OS), includes enabling a user to enter an instruction to start a hybrid-shutdown process, passing the instruction to an application that starts the hybrid-shutdown process, and requesting the OS to prepare for a hibernate state by saving a current system state as a last system state. The OS requests hardware to hibernate at the end of the hibernate processing. The method further includes capturing the hardware request from the OS to hibernate, turning off the computer system instead of entering into the hibernate state, and, upon a next power-on, performing a fast resume process from the hibernate state using the saved last system state to provide fui! functionality of the computer system.

The application 110 registers with the OS 130 so that when the hardware button 140 is pressed the OS 130 notifies the application 110 of the button event. The application 110 also may be automatically started by the OS 130 when the hardware button 140 is pressed
[0018] After receiving the button event notification from the OS 130, the application 110 starts the hybrid-shutdown process by requesting the OS 130 to prepare for a hibernate state and save a current system state as a last system state on. The iast system state may be saved, for example, on a hard disk drive. OS 130 may optionally enable wake-up events during the hibernate processing. At the end of the hibernate processing, the OS 130 requests computer hardware to hibernate.
[0019] The BIOS firmware 120 captures, i.e., intercepts, the hibernate request from the OS 130 to the computer hardware. After determining that the hybrid- shutdown process is in progress, i.e., that the hardware button 140 has been pressed, the BIOS firmware 120 configures the computer hardware to turn off the computer instead of entering into the hibernate state. The optional wake-up events are disabled, allowing the hybrid-shutdown process to save more power than the hibernate state. If, however, the BIOS firmware 120 determines that the hardware button 140 has not been pressed and the hybrid-shutdown process is not in progress, the computer enters into the hibernate state,
[0020] Upon the next power-on, the BIOS firmware 120 performs a power-on-self- test (POST) and passes control to the OS 130. The OS 130 checks if there has been any hardware configuration change since a previous power-off. If there is no hardware configuration change, the OS 130 uses the saved last system state to perform a fast resume process from the hibernate state to provide full functionality of the computer. Sf there are changes in hardware configuration, the OS 130 performs a full system boot
[0021] The exemplary system 100 for providing hybrid-shutdown and fast startup processes allows a computer to quickly return to its last state before power-off instead of going through time consuming hardware enumeration and configuration during a normal full system boot. The fast resume time can be, for example, less than 30 seconds. The system 100 enables fast system startup regardless of the number of pre-loaded software program as long as there is no hardware configuration change since the previous power-off. Therefore, PC manufacturers can freeiy add software without compromising the boot time. The system 100 is integrated into the computer's power-off path, thus delivering a true power-off state and the lowest power consumption Sevel to satisfy the industry's green PC initiative.
[0022] Figure 2 illustrates exemplary hardware components of a computer 200 that may be used in connection with the system 100 for providing hybrid- shutdown and fast startup processes.

The hard disk drive may be used to store the OS 130, the application 110, and the last system state.
[0026] The processor 150 may execute instructions to perform the method steps described herein. For example, the processor 150 may execute instructions to automatically start the application 110 or to notify the application 110 to request the OS 130 to prepare for a hibernate state when the hardware button 140 is pressed. These instructions may be stored in the system memories 162, the secondary storage devices 136, or optionally received from the Internet or other network.
[0027] The computer 200 also includes input devices, which may be any device for entering data into the computer 200, such as a keyboard 180, keypad (not shown): cursor-control device, such as a mouse 170, touch-screen (possibly with a stylus) (not shown), or microphone (not shown). The keyboard 180 may be a persona! system/2 (PS/2) keyboard or a universal serial bus (USB) keyboard. The hybrid -shutdown key 144, which may be a custom-designed key; is located on the keyboard 180 to allow the user to enter the instruction to start a hybrid- shutdown process. The keyboard 180 and mouse 170 are connected to the motherboard 124 through a keyboard connector 190 and a mouse connector 192, respectively,
[0028] The computer 200 also includes peripheral component interconnect (PCI) slots and/or PCI Express (PCI-E) slots (collectively 134) for attaching peripheral devices to the computer motherboard. The computer 200 further includes a display device 178, which may be any type of device for presenting visual image, such as, for example, a computer monitor, flat-screen display, or display panel.

The computer-readable media may include instructions for controlling the computer 200 to perform a particular method.
[0031] Figure 3 is a flow chart illustrating an exemplary method 300 for providing hybrid-shutdown and fast startup processes for the computer 200. The method 300 starts 302 by configuring the hardware button 140 to enable the button event to be notified to the OS 130 using corresponding hardware signaling and software programming (block 304). The method 300 enables a user to enter an instruction to start the hybrid-shutdown process by, for example, pressing the hybrid-shutdown button 142 or the hybrid-shutdown key 144 located on the keyboard 180 (block 306). The OS 130 passes the button event to the application 110 (block 308). The application 110 starts the hybrid-shutdown process by requesting the OS 130 to prepare for a hibernate state and save the current system state as the last system state on a hard disk drive (block 310). The OS 130 requests the computer hardware to hibernate at the enά of the hibernate processing (block 310).
[0032] The BIOS firmware 120 captures, i.e., intercepts, the hardware request from the OS 130 to hibernate (block 312). The BIOS firmware 120 determines if the hybrid-shutdown process is in process (biock 314), if no, the computer 200 enters into the hibernate state (b!ock 318), !f the hybrid-shutdown process is in process, the BiOS firmware 120 configures the computer hardware to turn off the computer 200 instead of entering into the hibernate state (biock 318).
[0033] Upon the next power-on, the BIOS firmware 120 performs POST before passing control to the OS 130 (block 320). The OS 130 determines if there is any change in hardware configuration since the previous power-off (biock 322). if yes, the OS 130 performs a full system boot (block 324), !f there is no hardware configuration change, the OS 130 performs a fast resume process from the hibernate state using the saved last system state to provide fuS! functionality of the computer 200 (biock 326). The method 300 ends at 328.
