WAIT. All is not lost yet, I'm a qualified repair technician (Seriously, PM me if you need proof). All is not lost just yet. There a few steps you can take from here to save your laptop. Most manufacturers include holes that pass through the keyboard and out the bottom of the device to avoid damage to the more important parts of the computer (RAM, HDD, CPU, motherboard, ect...) but for the love of god do NOT turn the computer upside down to drain the milk. If you havn't already, power it off and remove the battery/charger and dry up what you can see on the outside with a paper towel and put something between your desk and the computer overnight or at least for a few hours.
If you want to repair/replace the damaged parts (which only looks like the keyboard), look on Ebay or Amazon for a replacement keyboard that will fit your computer. You can do this by searching the model number of your computer which is normally found on the bottom of the device followed by "replacement keyboard" or similar.
After that, you have 2 options:
1:
Most if not all computer stores that aren't run by a mega corporation would be willing to take off some of the price of replacing the keyboard if you provide your own replacement parts but I can't really say to much about your area unfortunately. Its a small price to pay in comparison to replacing the entire computer.
or 2:
Attempt to replace it yourself. As scary as it may seem, its normally not hard to replace a keyboard on a laptop. On most brands and models of laptops you can pop off the upper region above the keyboard with a screwdriver letting you unscrew the keyboard and replace it. Just look up on Google/YouTube the model of your laptop followed by "keyboard replacement tutorial" and you should find something.
Other than that, good luck with getting it fixed.
