Dell Inspiron 5040N AC adapter Lost Power once plugged into Laptop
I have a Dell Inspiron 5040N Laptop that now has a Dead Battery due to lack of charging. Once the AC adapter is plugged into the Laptop the AC Module stops charging (green light goes off. I have tried another Ac Adapter and have even replaced the AC Power Plug on the laptop with the same results. I can not run any of the Tests due to battery is dead and Laptop will not turn on.

Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Three components cause this issue, in this order:
Adapter - you have already tested another adapter, so ruled out.
DC Port - the port that holds the adapter in, might be shorted - you would need this part - http://bit.ly/2bQ3HoP
Motherboard - I would primarily suspect this part, if the dc port does not fix the issue, then it is the motherboard that has failed and needs to be replaced.
If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
Personally, I would suggest, you invest your money on a new machine than to repair this old machine. However, it is your discretion.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
