RAR archive of about 219 KB for the Apple LED board numbered 820-2142, a small daughterboard tied to the indicator or backlight LED circuitry. No schematic number or revision appears in the name, so confirm the PCB marking before use. A technician refers to this kind of document to check LED supply voltages, driver signals and the connector pinout back to the logic board when an indicator stays dark. Extract it with a standard archiving tool such as WinRAR or 7-Zip to read the included files.
