Abstract: Examples associated with basic input/output system (BIOS) up-dates are described. One example method includes system management mode locking a first pre-extensible firmware interface initialization (PEI) region and a driver execution environment (DXE) region of a shared serial peripheral (SPI) chip of a BIOS of a computer. A second PEI region of the shared SPI chip is chipset locked. A record in a system management random access memory associated with a video option read only memory (ROM) is created. The video option ROM is loaded. The first PEI region is updated, and periodic graphical updates regarding the progress of updating the first PEI region are provided using the video option ROM.

Abstract: Examples of an apparatus, method, and instructions included on a machine-readable non-transitory storage medium are disclosed herein. In an example of the method, a first state is provided to enable a camera to record an image, a second state is provided to disable the camera, and a third state is provided to permit the camera to be enabled and disabled. Also in this example of the method, a button is actuated in the third state to an on position to enable the camera to record an image or an off position to disable the camera. Additionally in this example of the method, a signal is generated via an input device in the on position of the button to enable the camera to record an image or disable the camera.

Abstract: Example implementations relate to balancing a power load among USB ports. For example, an apparatus according to the present disclosure, may include a plurality of USB ports, and an embedded controller coupled to the plurality of USB ports. The embedded controller may determine that a first device is coupled to a USB port of the plurality of USB ports, and determine a power draw of the first device relative to a type of the USB port. The embedded controller may balance a power load among a remainder of the plurality of USB ports based on the power draw of the first device relative to the type of the USB port.

Abstract: An apparatus may include a basic input/output system (BIOS) coupled to a controller. A communication port may be coupled to the controller. The controller may determine that the communication port has entered a locked state, send a first signal to the communication port to power off a bus associated with the communication port for a threshold period of time, and send a second signal to the communication port to power on the bus associated with the communication port in response to expiration of the threshold period of time.

Abstract: In one example in accordance with the present disclosure, a computing device is provided. The computing device includes an interface module and a power management module. The interface module is to provide a user interface that facilitates enabling and disabling of an always on feature, and further facilitates configuration of a permissible advanced configuration and power interface (ACPI) S3 state period. The power management module to receive a request to enter an ACPI S3 state, determine whether the always on feature is enabled, and in response to determining that the always on feature is enabled, determine whether the computing device is within a user-defined permissible ACPI S3 state period. In response to determining that the computing device is within the user-defined permissible ACPI S3 state period, the power management module is to set a wake event and cause the computing device to enter the ACPI S3 state.

Abstract: Examples disclose a method, system, and computer readable media to configure a device within a computing system. The examples process configuration data when standby power is applied to the device. Additionally, the examples configure the device based on the configuration data, wherein the device is configured prior to initialization of the computing system.
