Start af Dell Diagnostics fra harddisken

Dell Diagnostics er placeret på en skjult partition med diagnosticeringsværktøjer på harddisken.

BEMÆRK: Hvis computeren ikke kan vise et skærmbillede, skal du kontakte Dell (se "Kontakt Dell"

iBrugervejledningen).

1Sluk computeren.

2Hvis computeren er tilsluttet en dockingenhed, skal du tage den ud af dockingenheden. Du kan finde vejledning i den dokumentation, der fulgte med dockingenheden.

3Tilslut computeren til en stikkontakt.

4Dell Diagnostics kan startes på to måder:

a Tænd computeren. Når DELL™-logoet vises, skal du trykke på <F12> med det samme. Vælg Diagnostics (Diagnosticering) i startmenuen, og tryk på <Enter>.

BEMÆRK: Hvis du venter for længe, og operativsystemets logo vises, skal du fortsætte med at vente, indtil du ser skrivebordet i Microsoft® Windows®. Luk derefter computeren, og prøv igen.

bTryk på <Fn>-tasten og hold den nede, mens computeren starter.

BEMÆRK: Hvis du ser en meddelelse om, at der ikke blev fundet en partition med diagnosticeringsværktøjet, skal du køre Dell Diagnostics fra Drivers and Utilities CD.

Computeren kører Pre-boot System Assessment (Analyse af systemet før start), som består af en række test af systemkortet, tastaturet, harddisken og skærmen.

•Besvar eventuelle spørgsmål, der stilles under testen.

•Hvis der bliver fundet en fejl, stopper computeren og udsender en biplyd. Hvis du vil stoppe analysen og genstarte computeren, skal du trykke på <Esc>. Hvis du vil fortsætte til den næste test, skal du trykke på <y>. Hvis du vil teste den komponent, der havde en fejl, igen, skal du trykke på <r>.

•Hvis der bliver fundet fejl under analysen af systemet før start, skal du notere fejlkoden/fejlkoderne og kontakte Dell (se "Kontakt Dell" i Brugervejledningen).

Hvis analysen af systemet før start gennemføres uden fejl, får du meddelelsen Booting Dell Diagnostic Utility Partition (Starter partitionen med Dell Diagnostic Utility) Press any key to continue (Tryk på en vilkårlig tast for at fortsætte).

5Tryk på en vilkårlig tast for at starte Dell Diagnostics fra partitionen med diagnosticeringsværktøjet på harddisken.
