This laptop is less than a year old (OS: Windows 10) and is getting the "plugged in not charging error." The unknown AC watt error pops up when booting the laptop and I have to unplug the adapter just to get to the desktop. The AC adapter will sustain the battery although it obviously drains over time when being used, but slowly. The AC adapter and battery are those which came with the laptop. Also, the backlight for the screen and LED light on the laptop do work when I plug in the adapter.
I have tried the following:
- BIOS reset - BIOS update - BIOS Diagnostic Test & Dell Diagnostic Test - Blowing into DC Jack - Testing a new Dell brand/approved ac adapter - Testing a new Dell brand/approved battery - and basically anything else Dell has suggested through its troubleshoot suggestions
Any other thoughts here? Next step is to contact technical support as the laptop is under warranty.
RE: Dell Inspiron 5559 (New) Plugged in Not Charging
Contact Dell for warranty support - one of three things is bad: the adapter, the DC jack in the system, or the mainboard. The warranty will cover the repair (assuming it's not due to a physically damaged adapter or DC jack).
