Abstract: Examples disclosed herein relate to power management in a blade enclosure. An intrusion detection mode is initiated by a baseboard management controller. Responsive to determining a power shortage in the blade enclosure, a stop clock pin is operated to control power consumption of a server in the blade enclosure. After a predefined time of determining the power shortage, a model specific register (MSR) associated with power settings of a Central processing unit (CPU) of the server is reconfigured. Reconfiguring the MSR comprises, identifying a power profile based on available power in the blade enclosure and modifying register states in the MSR based on the power profile via a baseboard management manager (BMC) of the server. Subsequently, operation of the stop clock pin is stopped.

Abstract: Examples disclosed herein relate to initializing a fan speed of a computing device using a high-water value when a pre-runtime event occurs. A management controller (MC) receives sensor data from sensors of the computing device. A fan speed of a fan is controlled using a fan control value based on the sensor data. The fan control value is monitored to determine a high-water value of the fan control value. The high-water value is stored in a location that is accessible by a pre-runtime fan control engine of the computing device. In response to a pre-runtime event, the fan speed is initialized to a speed using the high-water value.

Abstract: Examples relate to edge device disablement. In some examples, edge device disablement includes an edge device including a processing resource in communication with a memory resource including instructions executable to receive an indication of a disablement trigger associated with the edge device and responsive to the indication, reprogram a printed circuit assembly (PCA) of the edge device to render mechanisms of the PCA inoperable.

Abstract: One example includes a power-loss protection (PLP) module. The module includes a data bus and a plurality of connectors to enable removable coupling between a receptacle of a computer system and a plug-in module to provide electrical connectivity between the computer system and the plug-in module via the data bus. The module also includes a PLP controller to detect a power-loss event associated with the computer system and to provide auxiliary power on a power bus conductively interconnecting the computer system and the plug-in module in response to detecting the power-loss event.
