Patent ID: 11507464

Abstract:
A method of instructing a user prior to a boot-up process of an information handling system may include, with an embedded controller (EC) of the information handling system, executing a guided diagnostic flow module to: determine that a power-on process has been initiated at the information handling system; determine whether the EC detected a power sequencing timeout during boot up; and determine at which power rail boot-up has hung during the power-on process; and where the EC either determines that the power sequencing timeout has occurred, determining a fault at an issue-experiencing hardware component operatively coupled to the determined power rail. The method may further include sending a message from the EC to a timing controller (TCON) of a display panel of the information handling system, to initiate a guided diagnostic flow, the guided diagnostic flow including: providing, at the display panel via the TCON, diagnostics steps from flash memory as instructions to the user of the information handling system to guide the user to perform a manual manipulation of the issue-experiencing hardware component of the information handling system to address the fault.
