I had a bit of a disaster when my water bottle leaked inside my backpack, soaking my laptop. Luckily, the water only touched the bottom part of the laptop where some ports and ventilation are. I immediately dried it off and kept it in the same position. There was no water in the keyboard, just on the cover and sides. Once I got home, I turned it off completely.
I've placed it on a rack with a fan blowing on it, ports facing down, and I won't use the original charger since it got wet too. Instead, I've borrowed one but I'm concerned about using it tomorrow since I need the laptop for work. It'll have been about 18 to 19 hours since the incident—do you think it's safe to turn it on or should I wait longer?

If you can, remove the battery and keep it drying with a fan. You’ve got a good amount of time to dry it out, but don't rush it. Hitting the vents with some canned air could help too.
It should be fine, but let it dry as much as possible. Air movement helps a lot!
I often double wrap my laptop in plastic when riding in the rain, so I get where you’re coming from! Sounds like your water contact was minimal, so you might be alright, but it’s hard to assess without seeing it.
You’re likely okay, but I’d recommend getting it checked for any corrosion later on. If you feel comfortable, you could open it yourself, but tread carefully.
You're probably good to go by tomorrow. Just ensure it has dried out nicely before turning it back on.
