  • Patent number: 10884467
    Abstract: Techniques relating to communicating system events in universal serial bus (USB) power delivery (PD) devices are described. In an example, a USB PD controller receives a notification of a system event in a first device associated with the USB PD controller, the system event being based on one of a change in machine state of the first device and occurrence of a user interaction event in the first device. A PD protocol based message, indicative of the system event in the first device, is generated. The PD protocol based message provides for activation of a predefined profile setting in a second device, wherein the second device is to interface with the first device through the USB PD controller.

  • Patent number: 10872046
    Abstract: Network hardware of a computing device receives a network packet over a network to which the network hardware is connected. The network hardware determines that the network packet includes a power-cycling command. The network hardware, in response to determining that the network packet includes the power-cycling command, triggers a physical line between the network hardware and a power supply of the computing device. The power supply is connected to a power source and currently provides power from the power source to the computing device. In response to the network hardware triggering the physical line, the power supply interrupts providing the power to the computing device for a length of time to cause the computing device to restart and cold reboot.

  • Patent number: 10838479
    Abstract: A management device includes a processor that stores, in a second memory, power source information indicating first states of power sources of respective first electronic apparatuses included in an electronic apparatus group. The processor instructs, upon receiving a first instruction, the first electronic apparatuses identified by first apparatus information held in a first memory to transition the respective first states. The processor receives a second instruction to add a new electronic apparatus to the electronic apparatus group. The processor suppresses, in a case where any one of the first states is being transitioned, second apparatus information of the new electronic apparatus from being stored in the first memory. The processor stores the second apparatus information in the first memory in a case where transition of all the first states has been completed, and matches a second state of a power source of the new electronic apparatus with the first states.

  • Patent number: 10831252
    Abstract: Sub-components assembled into a computer are selected based on sub-component power efficiency levels (for example, low, medium, high) and/or anticipated usage of the computer. Multiple units of each type of sub-component (for example, a CPU) are tested to determine a power efficiency level of each unit. Computers in which sub-component efficiency levels are desired to match an overall computer efficiency level, receive sub-component units of corresponding efficiency level. Computers anticipated to run applications that make intensive use of a given type of sub-component receive the given units having a higher efficiency level. Computers anticipated to run applications that make little use of a given type of sub-component receive a physical unit having a lower efficiency level. Computers anticipated to run a wide variety of applications of no particular usage intensity for a given type of sub-component, receive a unit having an average efficiency level.

    Abstract: A management server exposes a web services interface through which managed clients that are not equipped with baseboard management controllers (“BMCs”) can submit management data at boot time. The firmware of the managed clients can receive management commands from the management server during boot time. The management server can also expose a web services interface to management clients through which the management clients can obtain the management data provided by the managed clients as if the management data were being provided through a BMC. The management server can also receive management commands from the management client computers for performance at the managed client computers. The management server queues the management commands for provision to the appropriate managed clients during the next boot of the managed clients.

  • Patent number: 10795427
    Abstract: A method from managing power state transitions in a computing system is disclosed. A processor may initiate a change in power state from a first initial power state to a first new power state and, in response to initiating the change, send an initial notification to a system integrated circuit using a first communication channel, and deactivate the first communication based on responses to the initial notification. The processor may enter the first new power state in response to the deactivation of the first communication channel, and send a final notification to a management controller using a second communication channel. The management controller may send a message to the system integrated circuit upon receiving the final notification. The system integrated circuit may then transition from a second initial power state to a second new power state based on the message.
