Abstract
An information handling system (IHS) includes a chassis. A processor is located in the chassis. A memory is located in the chassis and coupled to the processor. A disk drive is located in the chassis and coupled to the processor. An accelerometer is located in the chassis. A controller is located in the chassis and coupled to the accelerometer. The controller is operable, in response to a wake indicator signal associated with an IHS wake operation, to use the accelerometer to determine that the movement of the IHS exceeds a threshold and, in response, prevent the IHS wake operation such that operation of the disk drive is not initiated.
Claims13
A safe unattended wake system, comprising:
- a chassis;
- a component located in the chassis;
- a movement reporting device located in the chassis, wherein the movement reporting device is continuously powered during a system reduced power state;
- and
- a controller that is located in the chassis, coupled to the movement reporting device, and continuously powered during the system reduced power state, wherein the controller is configured to;
- receive a wake indicator signal associated with a system wake operation,
- retrieve a movement report from the movement reporting device;
- determine the movement report exceeds a threshold, and
- prevent the system wake operation such that operation of the component is not initiated from the system reduced power state.
An information handling system (IHS), comprising:
- a chassis;
- a processor located in the chassis;
- a memory located in the chassis and coupled to the processor;
- a disk drive located in the chassis and coupled to the processor;
- an accelerometer located in the chassis, wherein the accelerometer is continuously powered during an IHS reduced power state;
- and
- a controller that is located in the chassis, coupled to the accelerometer, and continuously powered during the HIS reduced power state, wherein the controller is configured to;
- receive a wake indicator signal associated with an IHS wake operation,
- use the accelerometer to determine that the movement of the IHS exceeds a threshold in response to receiving the wake indicator signal;
- and
- prevent the IHS wake operation in response to determining the movement of the HIS exceeds the threshold such that operation of the disk drive is not initiated from the IHS reduced power state.
A method for providing a safe unattended wake of an information handling system (IHS), comprising:
- placing a IHS into a reduced power mode, wherein a movement reporting device and a controller in the IHS are both continuously powered in the reduced power mode;
- receiving a wake indicator signal with the controller, wherein the wake indicator signal is associated with a IHS wake operation;
- retrieving, by the controller in response to the wake indicator signal, a movement report from the movement reporting device;
- preventing the IHS wake operation in response to the movement report exceeding a threshold;
- and
- enabling the IHS wake operation in response to the movement report not exceeding the threshold.
