Wirelessly network-connected, battery-powered information handling system featuring prevention of data corruption after wake-up by a network event
First Claim
1. An information handling system comprising:
- a processor;
a memory coupled to the processor;
a battery for supplying power to the system;
a wireless LAN controller, coupled to the processor, for wirelessly communicating with a network, the controller waking up the information handling system upon occurrence of a wakeup event on the network and in response checking the state of charge of the battery and sending the state of charge to the network for a determination as to whether or not the battery has sufficient energy to execute a particular service request; and
a remote manager for receiving state of charge information via the wireless controller and making the determination.

Abstract
A method and apparatus are provided for preventing data corruption in an information handling system when a server requests the system to perform a system management activity and the amount of battery energy remaining available to the system is not known by the requesting server. After waking up the information handling system from a sleep state, the server interrogates the system to determine the state of charge of the battery. The server considers both the remaining state of charge of the battery and the time and energy required to carry out the requested operation. If the battery has sufficient charge to carry out the particular requested operation, then the server instructs the system to carry out the particular operation. However, if the battery does not have sufficient charge to carry out the particular requested operation, then the server does not continue the requested operation or aborts the operation. In this manner, the possibility of the battery powered information handling system running out of energy during the course of an operation requested by the server and the concomitant data corruption, are substantially reduced.
