Hi flowerk,

I request you to check the Ac adapter status in the BIOS screen.  To go to BIOS restart the system and at Dell logo keep taping the F2 key every two seconds.  Please check the status for the ‘Ac Adapter type’. Also run a diagnostics on the battery. Click on the below link:

Under ‘Choose a Diagnostic Type’ select ‘Component’, from the  listed components under ‘Make a Selection’  select ‘Battery’ and then click on ‘Run Diagnostics’. Follow on screen instruction to run the test.

In case the AC adapter is listed in the BIOS and the Diagnostics on the battery passes, I recommend you to flash BIOS to the latest version by clicking on the link given below:

While flashing BIOS connect the Ac adapter and make sure the battery has minimum 15% charge as this needs uninterrupted power supply. Do not use the system till it restarts and comes up to the desktop.

In case the issue persists even after flashing BIOS, I request you to check with a known good Ac adapter and Battery.  Please reply with the status to assist you further.
