PAS PÅ: Misbrug af batteriet kan øge risikoen for brand eller kemisk forbrænding. Undgå at punktere eller brænde batteriet, og skil det ikke ad eller udsæt det for temperaturer over 60°C. Opbevar batteriet utilgængeligt for børn. Håndter beskadigede eller lækkende batterier med stor forsigtighed. Beskadigede batterier kan lække og medføre personskade eller skade på udstyr.

Kontrol af batteriopladningen

Dell QuickSet Battery Meter, Microsoft Windows Batterimåler og ikonet , batteriladningsmåleren og sundhedsmåleren samt advarslen om lav batteriladning giver oplysninger om batteriladningen.

Dell™ QuickSet Battery Meter

Hvis Dell QuickSet er installeret, skal du trykke på <Fn><F3> for at få vist QuickSet Battery Meter (QuickSet Batteriemåler). Batterimåleren viser status, batterisundhed, opladningsniveau og opladningsforløbet for batteriet i computeren.

Yderligere oplysninger om QuickSet finder du ved at højreklikke på ikonet

på proceslinjen og klikke

på Help (Hjælp).

 

Microsoft® Windows® Batterimåler

Windows Batterimåler viser den resterende batteriladning. Hvis du vil kontrollere Batterimåler, skal du dobbeltklikke på ikonet på proceslinjen.

Hvis computeren er tilsluttet en stikkontakt, vises ikonet .

Opladningsmåler

Ved at trykke én gang eller ved at trykke på og holde statusknappen på batteriladningsmåleren på batteriet kan du kontrollere følgende:

•Batteriladningen (kontrolleres ved at trykke på og slippe statusknappen)

•Batterisundheden (kontrolleres ved at trykke på og holde statusknappen)

Batteriets funktionstid bestemmes i vidt omfang af det antal gange, det oplades. Efter flere hundrede opladnings- og afladningscyklusser mister batteriet noget af dets opladningskapacitet — dets batterisundhed. Det betyder, at et batteri kan vise status "opladet", men have en reduceret opladningskapacitet (sundhed).

Kontrol af batteriladningen

Hvis du vil kontrollere batteriladningen, skal du trykke på og slippe statusknappen på batteriladningsmåleren for at få ladningsniveaulamperne til at lyse. Hver lampe repræsenterer ca. 20% af den samlede batteriladning. Hvis batteriet f.eks. har 80% af dets ladning tilbage, vil fire lamper være tændt. Hvis ingen af lamperne lyser, har batteriet ingen ladning.
