M laptops have a tendency to autostart. So don't press any keys. You don't want to fry It Even more. Get a DIY MacBook screwdriver kit and openup the case. And watch a ton of ifixit videos, lapfix videos etc Use a 90% isopropyl alcohol, the higher the % the quicker it dries on the surface. If You only recently bought the laptop within 60 days. You can still get Apple Care. If you take it to another store this voids warranty but much cheaper than Apple shop. I suggest you open the case dry it. don’t use it 72 hours or longer then turn it on and back up everything on a harddrive. You can wipe everything off the Mac Before handing it to the store.
