Description

Method and device for switching multiple operating systems in dormant state

technical field

The present invention discloses a method for switching multiple operating systems in a dormant state, and particularly relates to a method for switching a computer device in a dormant state with multiple operating systems.

Background technique

With the popularization of computer equipment prices, the number of desktop computers and portable computer equipment owned by consumers is gradually increasing. However, in order to meet the environmental protection considerations of energy saving and to extend the operation time of portable computers, computer equipment will Power consumption and management are an important consideration. For example, standby and hibernation modes are provided to save power. When users need to leave the computer temporarily, they can choose to put the computer into standby or hibernation mode to save power. When the computer enters the "standby" mode, the display and hard disk are in a state of stopping, so that the computer can reduce power consumption. When the user wakes up the computer again, it will quickly leave the standby state and the display screen will be completely restored. It is the screen when leaving. On the other hand, when the computer enters the "hibernation" mode, it will save the working state in the memory to the hard disk and then shut down the computer. Therefore, when the user restarts the computer, the data previously stored in the hard disk will be reloaded. Therefore, all the programs and files in use when the computer was turned off are restored on the monitor screen, that is, restored to the state when it was left.

At present, the computer power management follows the power management specification, and the advanced configuration and energy interface ACPI (Advanced Configuration and Power Interface) includes the following power states and modes from S0 to S5. Wherein, S0 is a state of full power consumption, that is, a state when the system is working normally. In addition, S1 (Standby) means that the system is in a low power supply state. In Windows or BIOS, it can be set to turn off the display signal output, stop the hard disk and enter the standby state, and the power indicator is blinking. At this time, move the mouse, Press any key on the keyboard to wake up the computer. However, the S2 (Power On Suspend) state setting is similar to that of S1. In addition, S3 (Suspend to RAM) is a low-latency sleep state. The memory data in this state is usually arranged by arranging the system RAM into a low-power automatic refresh mode, while other system devices are completely powered off. After restarting, the computer immediately restores to the screen before entering S3 after confirming the integrity of the memory data. In addition, S4 (Suspend to Disk) is a hibernation state with high latency but extremely low power consumption. The memory data in this state is stored in the hard disk, and will be restored quickly when the system resumes execution. Completely read the data from the hard disk to the memory without executing additional applications. Finally, S5 (Shutdown) is the shutdown state.

However, as the application of configuring multiple operating systems on a single computer device gradually increases, when the computer device is in a sleep state, please refer to FIG. 1, which is a method for switching between multiple operating systems on a computer device according to a conventional preferred embodiment. flow chart. In this embodiment, the steps included in the method are as follows: end the dormancy state in a dormancy mode of a first operating system, and read a pre-dormancy data from a hard disk into a main memory S11, and then, Close the first operating system, write a relevant data of the main memory back to the hard disk S12, then open and execute a second operating system and its application, and close the second operating system S13 after the application is completed, and then restart And execute the first operating system, and read relevant data from the hard disk into the main memory, so as to restore the state S14 before entering the sleep mode. It can be known from this that the multi-operating system switching method of the prior art is to switch between multiple operating systems by the user controlling each step flow one by one to wake up the computer device in a sleep state and then restarting the computer. , so, not only is the operating procedure complicated and inflexible, but also consumes more time and resources.

In view of the various problems of the conventional technology, in order to be able to solve both problems, the inventor has been engaged in firmware research and development for many years and a lot of practical experience, conceived and improved ideas, exhausted his personal professional knowledge, and through many researches and designs and Based on special discussion, the present invention proposes a method for switching between multiple operating systems in a sleep state as the realization and basis of the above-mentioned expectation.
