PAS PÅ: Hvis du bruger et inkompatibelt batteri, kan det øge risikoen for eksplosion. Udskift kun batteriet med et kompatibelt batteri, der er købt hos Dell. Batteriet er beregnet til at fungere sammen med din Dell™-computer. Brug ikke et batteri fra andre computere sammen med computeren.

MEDDELELSE: Du skal fjerne alle eksterne kabler fra computeren for at undgå risiko for skader på stikket. Oplysninger om udskiftning af det andet batteri, som er placeret i mediebåsen, finder du under "Anvendelse af multimedier" i Brugervejledningen.

Sådan fjerner du batteriet:

1Hvis computeren er tilsluttet en dockingenhed (tildocket), skal du tage den ud af dockingenheden. Du kan finde vejledning i den dokumentation, der fulgte med dockingenheden.

2Sørg for at computeren er slukket.

3Skub og hold frigørelsesknappen til batteribåssmæklåsen på bunden af computeren.

4Løft batteriet ud af batteribåsen.

Hvis du vil udskifte batteriet, skal du placere batteriet i båsen og trykke ned, indtil frigørelsesknappen til batteribåssmæklåsen klikker.

Opbevaring af batteri

Fjern batteriet, hvis du ikke bruger computeren i en længere periode. Et batteri aflades under længerevarende opbevaring. Efter en længere opbevaringsperiode skal batteriet oplades helt, før det bruges (se "Opladning af batteriet" på side 39).
