  • Embedded Controller (EC) 140 is a control system used to perform designated independent control functions and has a complex data processing capability. When the system is turned on, EC 140 controls the timing of most important signals. For example, in the following embodiments of this application, the EC 140 activates the CPU 222 to wake up the BIOS to perform BIOS update.

  • the system can be re-woken up by pressing the power button and other operations. After the system is woken up, data can be read from the memory immediately and restored to the previous working state of STR. Due to the extremely fast read and write speed of the memory, the time to enter and leave the STR state is shorter than the time to enter and leave the STD state.
  • the system entering S3 or S4 sleep can be realized through Advanced Configuration and Power Interface (ACPI).

Abstract

L'invention concerne un dispositif informatique et son procédé de mise à jour de système BIOS, ainsi qu'un support, se rapportant au domaine des ordinateurs. Le procédé de mise à jour de système BIOS comprend les étapes suivantes : un système d'exploitation d'un dispositif informatique entre dans un état dormant ; après que le système d'exploitation est entré dans l'état dormant, redémarrer un système d'entrée/sortie de base ; le système d'entrée/sortie de base obtient un fichier de mise à jour du système d'entrée/sortie de base et exécute une mise à jour du système d'entrée/sortie de base sur la base du fichier de mise à jour obtenu ; après que le système d'entrée/sortie de base est mis à jour, le système d'exploitation se réveille de l'état dormant. La mise à jour du système BIOS peut être achevée après que le système d'exploitation du dispositif informatique entre dans l'état dormant, sans redémarrer le dispositif informatique, et l'état de fonctionnement du système d'exploitation peut être maintenu avant et après la mise à jour du système BIOS.
