Okay, bad news is the laptop I spilled on still isn't working, so that sucks. Good news is I got an older laptop updated and working. It's slower and not as good, but it's far more preferable than no laptop.
I'm not super knowledgeable about this stuff, but I definitely hear something working inside. Dunno how to do what you suggested but I can look into it.
I did try the external screen thing, no luck there sadly. I was planning on giving it a few days rest and trying it again, see if that works. If nothing else I guess I'll just have to take it to some repair place and hope for the best.
