摘要： An information handling system includes an embedded controller and a memory device storing code that when executed causes the embedded controller to perform operations that includes receiving a request to change a security setting, determining a security policy associated with the security setting, and determining whether the change to the security setting deviates from the security policy. In addition, the embedded controller in response to determining that the change to the security setting deviates from the security policy, denying the request and reverting the change to the security setting.

摘要： An information handling system uses one connector for both liquid and air cooling and detects the type of cooling system installed. That provides the ability to choose the correct thermal handling table based on the installed cooling system. To detect the type of cooling system installed, a thermal management controller sets a control signal supplied to the cooling system through the connector to a first control value and determines if a tachometer signal supplied by the cooling system to the thermal management controller through the connector indicates a first type of cooling system. If the first type of cooling system is not detected, the thermal management controller checks if the tachometer signal from the cooling system with the control signal set at the first control value, or alternatively at a second control value, indicates a second type of cooling system. If no cooling system is detected, an error condition exists.

摘要： In accordance with embodiments of the present disclosure, a system may include a feedback controller and a comparator. The feedback controller may be configured to, based on a setpoint value and a measured process value calculate a first difference between the setpoint value and the measured process value and generate a controller driving signal based on the first difference. The comparator may be configured to compare a second difference between the setpoint value and a previous setpoint value to a predetermined threshold, determine if a magnitude of the second difference is greater than the predetermined threshold, output as an output driving signal the controller driving signal if the magnitude is not greater than the predetermined threshold, and output as the output driving signal a setpoint driving signal if the magnitude is greater than the predetermined threshold, the setpoint value based on the setpoint value independent of the measured process value.

摘要： An information handling system may include a processor, a display device communicatively coupled to the processor, and a basic input/output system (BIOS) communicatively coupled to the processor and configured to cause the processor to, during a pre-boot environment of the information handling system, collect contextual information regarding the information handling system, based on the contextual information, determine whether to enable soft keyboard functionality, and responsive to a determination to enable soft keyboard functionality, cause display of soft keyboard functionality to the display device.

摘要： An information handling system includes a memory that stores context data associated with a crash of the information handling system. A BIOS determines whether a crash of the information handling system occurred during a most recent operating system runtime of the information handling system. In response to the determination of the crash during the most recent operating system runtime, the embedded controller reads the context data associated with the crash of the information handling system. An embedded controller verifies a golden BIOS image for the information handling system, and sets an indication for an operating system of the information handling system to revert to original setting for a healthy boot.

摘要： An information handling system may include at least one processor, a memory, and an embedded controller (EC). The information handling system may be configured to, prior to initialization of an operating system of the information handling system: execute memory reference code configured to test selected regions of the memory; transmit results of the memory reference code to the EC; store, at the EC, information indicative of respective likelihoods that particular regions of the memory are bad; and upon a subsequent boot, select a region of the memory having a low likelihood of being bad for loading a Basic Input/Output System (BIOS) of the information handling system.

摘要： An embedded controller locks down one or more devices within an information handling system based on a detection of an operating system crash. A processor monitors an operating system executing within the information handling system, and detects the operating system crash. In response to the detection of the operating system crash, the processor notifies the embedded controller of the operating system crash.

摘要翻译： 根据本公开的实施例，系统可以包括反馈控制器和比较器。 反馈控制器可以被配置为基于设定点值和测量的过程值来计算设定点值和测量过程值之间的第一差值，并基于第一差异产生控制器驱动信号。 比较器可以被配置为将设定值和先前设定值之间的第二差值比较到预定阈值，确定第二差值的大小是否大于预定阈值，作为输出驱动信号输出控制器驱动信号if 幅度不大于预定阈值，并且如果幅度大于预定阈值，则输出设定点驱动信号作为输出驱动信号，该设定点值基于与所测量的过程值无关的设定点值。
