This computer was designed to work in harsh environments, meaning it can handle a little rain, cold, heat, and of course lots of vibration. This doesn’t mean you should drop kick the thing every time you get mad at Windows, but at the same time it would probably hurt your foot a lot worse than it would the computer. It is sealed very well to help prevent moisture or dirt from getting inside, but I’m pretty sure it would die if submerged. A little rain or snow probably wouldn’t hurt it, so long as the exposure wasn’t prolonged. Despite all the ruggedization, inside it is still a computer full of sensitive electronic components and such. It’s just not as sensitive as a $900 HP laptop you get off the shelf at Best Buy.
All of the ports, such as USB or VGA, are found behind closed panels that are sealed with a rubber gasket to prevent moisture from getting inside. You’ll need your fingernails to get some of the panels open, but that’s so they don’t easily spring open. The hard drive comes in a metal casing that is surrounded by foam so that it can take a pretty good hit and absorb most of the shock. It even has some heating elements in there to help keep the drive performing well in cold temperatures. In addition to the usual USB and other ports, this one even comes with a COM port, which you don’t often find on laptops these days. It does not come with a standard CD or DVD drive, so my work bought a CF-VDR302U DVD/CD-RW drive for each of our CF-30’s.
