Is the water fight in some way relevant here? Did the power go down because of the water fight? Just trying to rule out water damage, and weird stuff like water causing power to go out, causing some issues with the laptop while plugged in.

When does this error message show up? All the time? Only while plugged in?

Are you using a genuine AC adapter? What about the batteries? Are both the original ones that came with the laptop?

Assuming it's failing to boot, this could be BIOS level corruption, which probably won't be a fun fix.

You may have shorted it and damaged the power pack.

Try unplugging the AC adapter from the wall outlet and pc for 15 secs. Could also try another socket.

I'm going to interpret this something along the lines of "water in socket, flipped breakers or whatever, power out in house"

Checking for a genuine power adapter is typically handled at the BIOS level rather than the OS level. So I can think of two possible issues:
  • The external power brick got damaged in some way, and is no longer correctly reporting to the PC that it's a genuine power adapter
  • The BIOS (or wherever the check logic resides) is corrupt, so it's not doing that check properly

Problem is, I can't think of a reasonable way to test either one. You'd need a known good (read: genuine and working) AC adapter to test with, and given it's a compact PC I doubt you just happen to have another one lying around. And I wouldn't recommend buying on to test, since it could be an onboard problem rather than an issue with the adapter.

Really, you need to go talk to Dell about this. See if a Dell technician can help troubleshoot, see if there's warranty you can fall back on, etc. I suppose if you've not already, try plugging it into a different socket (ideally on a different circuit in your house). It's possible both the device and the adapter are fine, but the quality of power coming in is not and that's tripping the protection instead. I've seen that happen once, typically it's one of the other components that's gone bad, so I don't have much confidence in that explanation but it's worth a shot.
