I encountered a strange problem last night with my Dell XPS 15 laptop. It was working fine but then turned off, and would not turn back on. I held the power button for 30 seconds, tried everything, and to no avail. I later found out it had accidentally had water spilt on it - not a lot thankfully. I left it overnight.

Next morning, I turn it on and it works. It runs the BIOS screen and it says that the internal temperature was too high so had to power off. Laptop seems to be working normally. I plug in my charger and notice a strange burning smell. I quickly unplug it and realise the smell is coming from my actual laptop. I didn't notice if it was charging the first time, but when I plugged it back in after this, it had stopped charging and was not recognising charger at all. I turn it off and run BIOS and it says the AC Adapter isn't installed.

Not sure what else to do - tried to ring Dell and it wasn't helpful. Tried to google and have had no luck with my problem. I just want to know if it is my charger, my DC power jack or my actual motherboard (God forbid) that has the problem. 

Please, if anyone has any information, let me know!

Thank you.
