I accidently spilled some water on my laptop 5-6 months ago, it still works as good as ever?

I let it dry for about 10 hours when it happened, usual remedy- remove battery, turn upside down, remove power source.

It is still working today as good as when I first received it brand new. Should I be worried?
It was only a little bit of water.

The laptop is a DER NSW Lenovo ThinkPad edge 11, water resistant keyboard.

No… The first 24 hours are the big issue… If nothing has happened in 5 months nothing will happen…
