Spilled full cup coffee on Survey Book 2 -- STILL WORKING?

Hello,

Just wondering really why my NEW Surface Book 2 laptop is still working after I spilled a full cup of coffee with steamed milk onto the keyboard. I bought it, brought it home, charged it and then in morning sat down and leaned forward to plug something in and knocked over the coffee onto my new computer. Can you believe that? Not even 24 hours old!

The weird thing is that it's working for 3 days. I am not getting any errors. I'm just wondering if I should take it in because THANK GOD I BOUGHT THE ACCIDENTAL COVERAGE.

Should I do something to see if all components are working?
