RE: New battery Not working, Not a Dell battery "Plugged in not Charging" message
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
You could force update the BIOS if required - http://dell.to/2h9shSO
Having said this, we cannot assure that the non Dell batteries might work. If the adapter is detected in BIOS, then the adapter and dc port are fine and the battery might be at fault.
If the adapter or the dc port has an issue, then you might need to replace that.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
