Abstract

See full text

In some examples, a computing device may include a plurality of components, an embedded controller, and a read-only memory (ROM) to store a basic input output system (BIOS). A display device connected to the computing device may include a display panel and a timing controller. The embedded controller may be configured with instructions to determine that a power-on has been initiated, determine that a particular component of the plurality of components of the computing device has an issue that prevents booting the BIOS, and send a message from the embedded controller to the timing controller. The message may instruct the timing controller to display, on the display panel and before the CPU begins execution, one or more error messages associated with the particular component that has the issue preventing booting the BIOS. In some cases, a logo may be displayed along with the one or more error messages.
