My little one spilt a little water so I cleaned it up. But realized 3 hours later that there was underneath the laptop as well. I tried to turn it on but it just keeps beeping and the light near the battery blinks at the same time too. should I change the battery?
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.
