I accidentally spilt water on top of my chromebook. I didn’t immediatly turn it off but I did shake and wiped all the surface water immediately. Its been air drying for around 3 and a half hours now. It doesn’t seem to be powering on.

Hi @lienah
The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the laptop's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away
First do not try to charge or to turn on your laptop and then remove the battery as soon as possible from the laptop to minimize any further damage.
Then you need to dis-assemble the rest of the laptop and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better
Here is a link that describes the process. Electronics Water Damage
As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well
Hopefully after you have done all this the laptop might possibly work correctly again.
Here is a teardown video that may help.
If this process seems too daunting, take your laptop to a reputable, professional laptop repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.

One suggestion may help. Remove any and all covers to expose the laptop inner parts, check for remaining water and sop it up with tissues, napkins, Q-tips, whatever. Use canned air to blow off remaining water and napkins/tissues. If the battery is removable, disconnect it for removal and examine it for water intrusion. With exposed inner parts, lay the laptop upside down over a gas boiler. The warmth from a boiler or water heater will warm and accelerate evaporation of remaining moisture that can't be sopped up. Leave it overnight. A gas oven can do the same as the pilot light keeps the oven warmer than a room as it drives out humidity. The warmth from a closed oven's pilot light gently provides warmth to help evaporate moisture.
