- Some laptops are more vulnerable to damage from a spill on the keyboard than others, and it doesn't always have anything to do with the price tag. Some keyboards have a thin rubber membrane beneath the keys with electrical contacts molded right into little domes under each letter; that design may feel squishy and cheap to some users, but it stands up better to a splash or a flood than a more traditional design with springs and exposed contacts. How do you know which type of design you have? Take a look for yourself by prying off a keytop; if you're shopping, you may be able to get the information from the manufacturer or a dealer.
The best way to prevent damage from a mix of liquid and electronics is to keep them as far apart as possible. Keep your laptop far away from cups of coffee, glasses of water, and cans of soda.
