Abstract:
A computer system is monitored by firmware for a non-conforming state. Upon detecting the non-conforming state, firmware of the computer system outputs a keyboard code that causes an operating system to enter a predetermined state, such as a lock screen or other quiescent display state. A human-perceptible message is displayed at a display device after outputting the keyboard code.
