Hi Vasu212,

Please refer the following link which has troubleshooting steps for “battery not charging” issue: http://dell.to/ZbIDbk 

Also, connect a different Ac-Adapter and check if that works.

Please post the results.

Hi Nikhil, I read the instructions given in the link. Still I'm facing the same problem. Although I have not connected another charger. One more thing I would like to bring to your notice is whenever I connect my charger, I receive the error message and on bringing my cursor on the battery icon, it shows battery not charging. I disconnect the charger and connect it again. After 5-6 attemps the battery charges. And sometimes it doesnt.

Hi Vasu212,

Please check the AC-Adapter type in BIOS. To enter the BIOS screen, Switch on the computer, tap F2 at dell logo.

If the AC-Adapter type is” Unknown “or “None”, BIOS update can fix the problem. To update the latest version of BIOS:

1. Click this link: http://dell.to/17F08dH
2. Enter the service tag of the system, and select Drivers and Downloads tab.
3. Select the operating system from the dropdown and download the latest version of BIOS listed under BIOS category.
4. Ensure to connect the AC Adapter to the computer and the Battery level is above 15%.
5. Close all the open programs and make sure to save all the data in the computer.
6. Run the previously downloaded BIOS setup file and follow the on-screen instructions to update the BIOS.
7. Restart the computer when prompted.

Please post the results.

This indicates that the problem is hardware related.

Let Dell send you a new power adapter and if this doesn't fix the problem have the mainboard/power jack replaced.

The important thing is that your problem gets fixed as as long as your system is under warranty.Once you are out of it you will have to pay for any replacement parts.No need to tell you that a possible mainboard failure is quite expensive.Once your system has been repaired under warranty make sure the problem is really gone !

Hi vasu212,

The issue is with the DC-In port, which needs to be replaced.

If the computer is under warranty, I would be glad to arrange a service on the computer. Check warranty status: http://dell.to/13VPd97

Please private message me the service tag, registered owners name, primary and alternate phone numbers, and address.

In case of expired warranty scenario, we would not be able to extend warranty entitled services.

If the warranty on the computer has expired, below link would help you in contacting expired warranty services (this is for US based customers): http://dell.to/VPYT4T

Awaiting your response!
