RE: Battery Problem in Dell 5521
Thanks for writing to us.
Can you provide us some more info as requested below.
Have you tried charging another battery on this laptop or this battery on another laptop?
What does the ac adapter status show in BIOS?
How about battery health ?
Does it always show 80% plugged in not charging or does the status change if the charge is below 80%, (for example 70% plugged in charging and then it changes to not charging once 80%) ??
