Abstract: Electronic device 100 comprising a component 120 to generate diagnostic information indicative of a fault occurring in the electronic device; and a persistent display (electophoretic display, cholesteric liquid crystal display, electronic ink, e-ink) 140 coupled to the component and adapted to display the diagnostic information. Diagnostic information comprises an error code or a bar code. When the electronic device loses power, the persistent display retains its stable state and the displayed diagnostic is retained on the display. This obviates the need for expensive return material authorization procedures.
