Problems solved by technology
[0007] ACPI has the ability to go deep into the operating system to detect when and under what circumstances the user needs and does not need any functions, and provides unified power management rules to reduce the probability of misjudgment and improve reliability, and can define and manage More power-saving modes; when the information processing system is in normal operation, the battery power will be consumed all the time, but the user chooses not to act in the low battery alarm (Low battery alarm) option of the operating system (OS), and the information processing system When the AC-adapter is not connected, when the battery power of the information processing system drops to a critically low battery, the information processing system cannot give any warning or prompt to the user of the information processing system , causing the information processing system to shut down due to power exhaustion (Power Off), instead of a normal shutdown (shutdown)
[0008] Based on the above situation, it will seriously affect the normal operation of the information processing system, cause troubles for users, and even cause the operating system (OS) to operate abnormally because the file modification data is not written back to the hard disk, resulting in damage to the entire operating system. unresolved problem

The present invention discloses a forced shut-off device and method for one kind of high-grade configuration power interface. The high-grade configuration power interface is used to detect the state of battery and is connected to embedded controller and operation system. When the battery for information processing system has power capacity lowered to some low level, a signal is provided to the operation system and the operation system judges for forced shut-off before the battery is exhausted.
Description
technical field [0001] The invention relates to a forced shutdown device of an advanced configuration power interface, which can be applied to a portable information processing system adopting the advanced configuration power interface. Background technique [0002] Notebook computers are developed in response to the needs of consumers for portability. The biggest difference between a notebook computer and a desktop computer is that the former sometimes runs entirely on batteries. The length of battery life not only affects the length of use by consumers, but also meets the requirements of thinness, lightness and compactness to reduce the burden on consumers. Therefore, the power management function of the battery becomes the most important link in the battery technology of the notebook computer. [0003] There are currently two ways to increase battery life without increasing battery weight: (1) in terms of battery chemistry, develop different battery materials; (2) in te...
