After six MacBooks arrived at our bench with liquid damage in just one week (and it’s only Wednesday), we thought it was time to write a guide for what to do if this happens to you.

Remember, an ounce of prevention is worth at least $1,000. Try to keep your computer away from wet places like kitchen counters, sinks, and swimming pools. And—this may be the hardest thing of all—make it a habit never to place your beverage container next to your laptop. All it takes is one strategically placed droplet of water to turn your MacBook into a very expensive paperweight. We know this is common sense, but it bears repeating.

Now…what to do when the unthinkable happens?
