I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but discovered it sits in a frame with and has a 5-wire connector BLK-BLK-R-R-B, and although it was securely plugged into the MB, I see what looks like possible burn marks from the two BLK wires near the top of the connector in the photo.

Does this look like the type of fry that would cause the symptoms that I'm seeing? What other testing can I do to validate the cable and the battery itself? I don't want to just throw parts at this if I can avoid it. I can use a multimeter...just point me to the test points and the acceptable values. T​he MB inside says it's a ADM70 LA-C631P, REV 1.0(A00) 2015-10-23
