water / champagne on keyboard dell xps 15

@hanslange6039 you will have to treat it like you would any other water damaged device. For now you should stop continuing to try to charge or otherwise using your laptop. This potentially can make a bad situation worse.This may further damage your phone.

The next thing to do is to clean it. Disassemble your laptop using the Dell XPS15 7590 Service Manual. Remove the motherboard (and any other board your laptop may have) You must remove all EMI shields of the board(s). If you do not remove those, you might as well not do anything. After you removed those, clean the whole board, connectors and all with +90% isopropyl alcohol. Follow this guide Even so it was written for an apple iPhone 3G, all the points are still pertinent to your laptop. While you clean your board, check for any obvious damage, like burned or missing components etc.

All these steps are to avoid delayed failure caused by corrosion. Best thing to do would be to clean it with an ultrasonic cleaner, but if you do not have access to one, this will at least help. You also want to clean the top case and possibly replace the keyboard, which is what I would do if this was my laptop. Check the on/off switch as well. Once all this is done, reassemble your Dell and reevaluate. Until it is cleaned, everything will only be a guess. If you come across anything that looks weird or that you want to know more about, post a couple of pictures with your Question. That way we can see what you see and hopefully help you out further. Even with all this, water/champagne damage has only a small chance to be fully repaired, but at least you can give it a try.
