Chosen Solution
Hello, brilliant minds. Yesterday morning I installed a new original Dell battery in my XPS 9570. In the evening I was watching some video and then heard a somewhat loud POP, and then my screen turned black/the computer shut off immediately. I pulled out the DC jack, opened the laptop, and disconnected the new battery.
I measure 3 ohms and 7.9 ohms when probing the highlighted and nearby components, which I believe are capacitors. Would that be a short? I cannot find any other places where I measure such low resistance over a cap. How should I proceed? Can I damage the laptop any further by connecting power? Can my new battery have caused this, if so how? Would I be best off just taking the laptop to professionals? Edit: I found a schematic, but I do not know what the powerline is for.

@zoneknud, The first thing to do, you already did; Remove all forms of power! Next you’ll want to remove all boards (logic board and all daughters boards) and inspect both sides of them for burn marks, scorched or singed traces, etc. A loud popping noice is usually caused by a blown capacitor or a blown mosfet. If you take your boards out and take some good quality, up close and high resolution pictures (remember good lighting) and update your question using Adding images to existing questions, we can see what you see.

In addition to what @geirandersen has said. The Power rail is labeled as VCCGT. Which is a power rail for the CPU. Those typically have a low resistance to ground, so I’m not entirely sure I would be concerned. That’s pretty low. But not unheard of for similar rails. If there was a loud pop, there is almost certainly some kind of visible damage. It’s possible the new battery caused it if it was not the correct battery, or the battery was faulty, but it’s also possible the timing was just a coincidence. You will definitely want to give the whole board a good once over. Remove the heat sink even since it’s possible the issue is under it.
