I spilt water on the keyboard, and the screen instantly turned black. I tried to turn off the laptop using the power button but nothing has happened, the fans are running very high and the charging led is solid white and the caps lock led is flickering white. The battery is non removable and I dont have a small enough screwdriver to remove the cover. Is there any way to switch the laptop off as I am worried about leaving a wet laptop switched on overnight?
However ... it's most likely that SOME damage was done, regardless of how quickly you turned off the laptop and what you did afterward. The key problems are only the surface and almost certainly, more damage was done than that.
The ONLY way to know for sure is to take or send it to an HP Service Center and pay a LOT of money for them to run full diagnostics on it, and after that, to disassemble it to repair or replace any damaged components.
And, if the motherboard is damaged, the cost of repair can easily exceed the cost of replacing the laptop -- because (as far as I know) liquid spill damage is NOT covered under the warranty.
