Diagnostiklampor

Som hjälp vid felsökning har datorn utrustats med de fyra lamporna “A”, “B”, “C” och “D”. Diagnostiklamporna finns på minitorndatorns bakpanel och skrivbordsdatorns framsida. När datorn startar normalt, blinkar lampan. När datorn har startat lyser alla fyra lampor med fast grönt sken. Om datorn krånglar identieras felet med hjälp av färgen och ordningen på lamporna.
