Water spill on keyboard. After opening and drying computer ok, mousepad not working sound at maximum

[greyolddave]

Wife poured water on Pavilion X360 laptop . I followed directions, opened up and got the water out.  Let it dry. After reassembly  find that the computer and all works fine.  However:

1. mousepad does not work. External Logitech mouse works fine.

2. sound is at maximum and little volume icon at top left of screen shows 100%. Adjusting sound via settings or via hidden icons does not work.

Thanks for any assistance.

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

Spilling liquid on a laptop is the second-most damaging thing you can do to it (first is dropping it on a hard floor).

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:
