My laptop suddenly doesn't turn on and shows no indication of being charged.
Last thing that happened when I turned on my laptop was the showing of my home screen dimmed for a second and then it flickered off.

Only two things could be the reason for me:
1.) I spilled a bit of water on the keyboard, but after cleaning it off, was still using the laptop for an hour or so.
2.) It was incredibly hot today, and the laptop was left in the car for a bit.

I've opened up my laptop and removed the battery. I did find very minuscule amounts of water on the plastic sheets put on top of certain parts of the laptop's main board. Putting the battery back in, a small led indicator light will flash and pressing the power button that light will flash. As of now, I have the laptop unplugged, battery removed completely, and have held the power button for 30 seconds to completely discharge it. What should I do now?
 
You're going to want to let the machine dry for a while - take out the major components (HDD, RAM, Battery, etc) and let it air dry for as long as possible. Check it carefully for corrosion after that - you'll want to check the battery terminals, ram contacts, etc very carefully, as they'll be easy places to spot corrosion. After the machine is thoroughly dried, it MAY power back on

A household Fan trained on it as well. will help speed up the drying process.
Having droplets of water even inside on the motherboard tells me, it's had a fair baptism.
I wouldn't even attempt to power up, in under 4 or 5 days, minimum.
Excellent advice from @FreeBooter
Fingers crossed for you.

It's dead. The laptop never turned back on and cannot charge. Thanks for the help though!
