Computer system and data recovery method for a computer system having an embedded controller

摘要

A computer system and a data recovery method are provided. The computer system includes an embedded controller (EC). The data recovery method includes following steps. When the computer system stores data into the EC through a basic input/output system (BIOS), the data is backed up into a non-volatile random access memory (NVRAM) by the BIOS. The EC enters a power-off mode. The data is obtained from the NVRAM and is stored back to the EC after the EC leaves the power-off mode. Accordingly, the EC recovers from the power-off mode.

1. A data recovery method for a computer system having an embedded controller, comprising:
when the computer system stores data into the embedded controller through a basic input/output system (BIOS), backing up the data into a non-volatile random access memory (NVRAM) storing the BIOS; the embedded controller entering a power-off mode; and obtaining the data from the NVRAM and storing the data back to the embedded controller after the embedded controller leaves the power-off mode; wherein the step of storing the data back to the embedded controller comprises: activating the computer system by the embedded controller; obtaining the data from the NVRAM by embedded controller through the BIOS; and turning off the computer system by the BIOS or the embedded controller after the data is obtained.
