XPS 15 9550 unexpectedly shutdown - flame & smoke

 Hi,

My Dell XPS 15 randomly shutdown while I was using it. Immediately after, a small flame/light popped up from the cooling vent followed by some smoke (note: the light on the adapter also turned off).

After unplugging the adapter and the peripherals, I turned on the laptop and it seemed to work fine except the fact that the nVdia GPU is no longer detected.

I would like to mention that I received a message from Dell a couple of weeks prior notifying me that the battery on my model is faulty and I should order a new one free of charge. I did just that and, after a short delay due to the battery being out of stock, my battery finally arrived 2 days after the laptop short-circuited (or whatever happened to it that caused it to produce a flame and smoke like that).

I ran all of the possible diagnostic scans and nothing else seems to be broken except the fact that it seems that the nVidia GPU is no longer connected at the hardware level properly. The video card does not show up in either the Windows device manager or in BIOS. I assume the nVidia GPU is dead.

I am writing this because, first of all I need assistance with my device, but also these sorts of accidents could indeed harm somebody, especially if their Dell notebook catches fire while they are not nearby the device.

I would be grateful for any kind of advice on what I should do next.
