Spilled water on my brand new acer laptop, confess?

I just spilled water on my new acer laptop and then turned it on without realising. it just beeped alot and i turned it back off. i have got a standard one-year warranty from an independent dealer. shall i confess or just feign ignorance and ask them to fix it?
