Hi,

This could be a possible case of systemboard or charger being faulty.

Now that you have mentioned that with a different charger the same issue is seen in the system BIOS. If the same issue is seen with a a different charger then its a case of systemboard failure. 

Do send the service tag of the system along with system owner's name, contact no so that we can check the details and assist you further.

As requested, please see TAG and Owner's name below.

Hi Nee,

Thank you for the reply! Do send the service tag of the system via private message so that I can check the details to resolve the issue.

What is the private email I send my details and TAG to?

Unless you're certain there's a warranty on the system, it won't make much difference.  If you want to check, you can use the service tag at support.dell.com to look up the warranty status.

If the system is in warranty, then call Dell for repair. 

If it's not, the next thing to try is replacing the DC power jack:

If that doesn't solve the problem, it's the mainboard that will need replacement.  This will run upward of or over $300 -- and on a budget system of this age, may make replacing the system a better idea.

Hi,

Just a quick message to check if the issue with your system is sorted. But if there are more concerns just send the service tag of the system via private message.

 I have a similar issue with an Inspiron 15 3251. The battery was not charging, and I got
the same error message about the adapter. And it happened on the same day. However, my laptop operates just fine when plugged in. And, my adapter is the original
I have done a lot of diagnostics, using the Microsoft Device Manager and Dell's own System Detect. Consistently, they say the adapter and the battery are functioning correctly. Dell's web site suggests the BIOS may ha e shut down charging to prevent damage after sensing that the power levels are not standard. However, the computer seems to be fine. Also, System Detect and the web diagnostics report that the relevant BIOS and video drivers all are up to date.
One thought I had was that this could be the result of another disastrous Dell Update, such as the August 28 BIOS update that uninstalled the Intel Rapid Storage driver. I'm out of warranty, and Support refused to help even though Dell caused the problem. After six weeks of frustration, I finally got a Windows expert who found the Intel driver was missing.

Anyway, do you know how to restore the BIOS to a functional state?
Thanks.
