Method and system for restoring system configuration after disorderly shutdown

Abstract

Disclosed are techniques for recovering system configuration settings, such as remote management, of an information handling system following a disorderly shutdown. A restart controller detects a disorderly shutdown of an information handling system and, in response, sets a disorderly shutdown flag and restarts the information handling system. During the restart, the basic input/output system (BIOS) checks the disorderly shutdown flag as part of its power-on housekeeping. In response to determining the disorderly shutdown flag has been set, the BIOS reconfigures the system configuration settings, such as the power management scheme, of the information handling system so as to enable one or more remote wake mechanisms, such as wake-on-LAN or wake-on-ring. The BIOS then performs an orderly shutdown of the information handling system to place the information handling system in a low-power state, from which the information handling system can be awoken via the remote wake mechanism.
