shutting off randomly and suddenly without warning

[nyildiz]

Hello, I spilled a half cup of hot tea on my pavilion x360 and after I tried to dry and clean it, it was opened. But while I was working on it, it started to shut down suddenly and randomly without giving any error or message. I run the diagnostic tests and it passed them all but still continues to shut down suddenly and do not restart. Could you please provide me any guidance on how to proceed?

You probably shorted out the system board.

Turn the laptop OFF -- and do NOT turn it back ON!!

Here are some tips on dealing with liquid damage: http://www.makeuseof.com/tag/you-just-spilled-water-or-coffee-on-your-laptop-heres-what-you-should-d...

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.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
