Abstract: An example device comprises a plurality of components and a BIOS includes a non-volatile memory having instructions stored thereon that are executable by a processor of the device to cause the BIOS to determine a component identification (ID) of a component of the plurality of components, and fetch a plurality of recall component IDs. The instructions also are to cause the BIOS to compare the determined component ID with the plurality of recall component IDs. In response to a correspondence between the determined component ID and one recall component ID of the plurality of component IDs, the BIOS is to transmit signals representing a prompt to place the component of the plurality of components in a safety mode. The instructions also cause the BIOS to receive signals in response to the prompt and, responsive to the received signals, disable the component of the plurality of components.

Abstract: An energy storage device includes an integrated fuel gauge that is operatively connected to the energy storage device. The fuel gauge evaluates an operating parameter of the energy storage device and dynamically determines a state of charge. The fuel gauge communicates a communication including a requested operating parameter to the charging component with the single communication line and the signal indicates to an operating system component a change of an energy storage device state. The signal is used to trigger an alert or interrupt that causes the operating system component to display the change of the energy storage state based on the signal.

Abstract: A system according to examples of the present disclosure includes a battery charger electrically coupled to a battery and a battery charging circuit. The battery charging circuit includes an operational amplifier having a negative input to receive a pre-bias voltage, a positive input, an output, and a voltage offset. The battery charging circuit also includes a charge controller having an analog-to-digital converter to receive a voltage output from the output of the operational amplifier and a voltage supply to supply a voltage input into the positive input of the operation amplifier to cancel the voltage offset of the operational amplifier. In the example, the voltage output of the charge controller is a function of the voltage input of the charge controller.

Abstract: A system and method for enabling a computer user to switch between a higher resolution display and a lower resolution display, or to display simultaneously with both displays, while the operating system is active, the higher resolution display displaying with a higher resolution than the lower resolution display. More particularly, video device drivers are provided with the resolution characteristics of the two displays. The system management BIOS generates an event in response to a user pressing a predetermined keyboard "hot key". The operating system detects the event and broadcasts the event to video device drivers. The video device drivers then adjust the resolution, resize and move an application or applications under execution to properly fit on the display.
