I would order a new battery if i knew that was the issue, but i've had both the AC adapter and battery fail in laptops before, never had these symptoms, yet both my batteries and both my adapters have the exact same issue even as i switch between the 2 to diagnose?
Inspiron, it's out of warranty, it sounds like the DC port as i've been having issues with it being loose and lack of contact for a long time before this happened, this seems to be a progression of the issue, thanks.
Thank you for the update.
Yes, I would also suspect the dc port since both the adapters say none in BIOS and the fact that the port itself is loose.
You could contact our support team via the link in my previous post and get the parts replaced.
Let us know if you have any other queries.
