Have you tried a system reset yet? Usually a plugged in not charging message is displayed when you hover on the battery icon. Disconnect the battery and unplug the adapter. Then press and hold down the power button for 30 seconds. Then reconnect everything and try again.

Hello JOcean

Hello JOcean

My apologies for not replying earlier, i was held up in many things.

I tried the steps you suggested but the problem still persisted.

Please find the details of battery stats along with the message i get highlighted in red circle. 

This is the problem i have been facing.

Thanks in advance.

hi did you ever figure out a solution to this problem?

Errr no. I dumped that laptop and built my own new rig ... peace of mind when you know each and every part.

Hi @FlashFlame  from the battery information provided, it has reached end of useful life and wants OEM replacement. Laptops without battery are designed to function as a desktop with adapter plugged in. This gives opportunity to get a replacement battery. 

For the typical user, noticeable reduction in battery run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced within 18 months. Dell recommends buying a new Dell laptop battery when the run time does not meet your needs. Dell Laptop Battery - Frequently Asked Questions | Dell US
