Abstract: In one or more embodiments, one or more systems, methods, and/or processes may determine if a user is in contact with an information handling system. If the user is not in contact with the information handling system, the information handling system may utilize a thermal profile. If the user is in contact with the information handling system, it may be determined if the user is in contact with a first display of multiple displays of the information handling system. If the user is in contact with the first display, processing of information may be migrated from a component associated with the first display to a component associated with a second display of the multiple displays. If the user is not in contact with the first display, processing of the information may be migrated from the component associated with the second display to the component associated with the first display.

Abstract: Controlling an activation status of a proportional-integral-derivative (PID) controller for an information handling system cooling system, such as the on/off status of the PID controller, can reduce power consumption and processing and memory requirements for such a system. A decrease in resource consumption can be realized by deactivating the PID controller during certain periods and activating the PID controller during others. For example, the PID controller can be deactivated when a temperature of a system component falls below a threshold temperature and activated when the temperature of the system component rises above the threshold temperature.

Abstract: In some examples, a computing device includes a first display in a first housing and a second display in a second housing. The computing device may determine an angle between the first display device and the second display device, determine a first temperature map of the first housing based on the angle and first temperature data received from a first set of temperature sensors in the first housing, and determine a second temperature map of the second housing based on the angle and second temperature data received from a second set of temperature sensors in the second housing. The computing device may determine a temperature difference between the first display device and the second display device, determine an action, and perform the action to reduce the temperature, color, and/or color intensity difference between the first display device and the second display device.

Abstract: Adjusting a cooling fan speed control profile to account for system implementation factors, such as ambient temperature and usage history, can optimize power consumption and reduce the volume and variation of sound generated by shifts in fan speed in response to changes in system and component temperature. Adjusting a cooling fan speed control profile may include adjusting a maximum fan speed based on an ambient temperature or component temperature of the information handling system.

Abstract: A convertible information handling system in a clamshell configuration provides a maximum housing surface temperature at a predetermined portion, such as a fan exhaust, that is greater than a maximum temperature in a tablet configuration. Upon detection of transition to the tablet configuration, a burst application by a thermal rejection device reduces the temperature at the predetermined portion to aid in achieving the maximum temperature of the tablet configuration. For example, a burst application may include running a fan at full speed for a defined time or decreasing a pressure within a vapor chamber.

Abstract: Control signals, such as PWM control signals, can be used to control aspects of a cooling system and can be generated using proportional-integral-derivative (PID) control. PID control systems for cooling systems are designed based on default environmental and system characteristics and pre-programmed for operation prior to delivery to customers or end users. Changes in environmental and system characteristics, such as component aging, environmental variations, and variation in manufacturing from system to system, such as heat sink effectiveness and application of thermal pastes, can impact system level performance of the control system. Adjusting gain parameters for the P, I, and D components of a PID control signal can reduce negative impact on system performance resulting from such changes and allow the control system to better adjust to external factors.

Abstract: A method for cooling system components of information handling systems may include generating a first pulse width modulation (PWM) control signal for controlling at least one cooling fan configured to cool a system component, filtering the first PWM control signal, and applying the filtered first PWM control signal to the at least one cooling fan. The first PWM control signal may be used to control a component fan and then filtered to generate a filtered first PWM control signal used to control a system fan. The filtering of the control signal may include dampening the control signal such that the control signal is less responsive to temperature changes as the temperature nears a set temperature.

Additionally, in certain embodiments, the power management operations allow power messages be to communicated among the plurality of information handling system. In various embodiments, a power state of each system is checked and if there is a change in system context or power state in one of the communicating systems, a message is generated and provided to other linked systems. The receiving systems can now change their respective power state based on the message received.
