AUSTIN, Texas — Inside a system coated in white powder, I may see — if I squinted — what seemed to be a computer. In reality, it used to be one in every of Dell’s Rugged laptops in the course of a dust-ingress examine, in one of the crucial rooms on the corporate’s Excessive Computing Take a look at Lab.
The computer would fail the examine, I am instructed, if any observable grime used to be deposited within the unit. And the examine spends as much as eight hours coating the Rugged pocket book in grime.
This and plenty of different assessments in response to the Mil-Spec 810G requirements are carried out at this facility, the second one model of Dell’s rugged trying out area. My excursion used to be led via Anthony Bundrant, an engineer who is been operating for Dell since 2012, when Dell got the ruggedized-hardware company Augmentix, the place he labored for years prior.
Bundrant instructed me concerning the historical past of Dell’s ruggedized laptops and pills, which started when the corporate noticed Panasonic roll out identical merchandise. Dell determined to make laptops that met and exceeded the criteria of its competitor. But if early releases failed to carry as much as buyer trying out, Dell added extremely sped up existence trying out (HALT), which appears to seek out how smartly a computer will age. This system takes a couple of measures, together with the use of liquid nitrogen for injection cooling within the HALT chamber to impulsively trade the air temperature.
However whilst Dell builds Rugged laptops to live on the pains of the actual international, the power’s drop assessments are extensively utilized to check Chromebooks. Bundrant instructed me it’s because children, who’re a few of the number one customers of Chromebooks, are as unhealthy as any paintings atmosphere.

The primary examine we noticed gave the look of a easy hinge examine, nevertheless it grew to become out to be an analysis of the reliability of the reveal cables throughout the hinge. That is paying homage to the “Flexgate” flaw that is reportedly inflicting deficient lighting fixtures in Apple’s MacBook Professional laptops.
After the display-cable examine, we noticed the drop-test spaces, the place laptops fall from 6 toes within the air onto a 2-inch-thick piece of plywood, a complete of 78 occasions, from a ton of various angles. Dell additionally drops laptops on a thick sq. of metal.
Subsequent, I were given to peer the Thermotron machines, which carry out excessive local weather assessments, subjecting laptops to temperatures of as much as 160 levels Fahrenheit and as little as minus 20 levels Fahrenheit. Those machines are saved in their very own room, I came upon, as a result of they may be able to make their very own area lovely scorching.
In some other room, Dell confirmed the grizzly corrosion of its liquid-salt room, as Bundrant pulled again the lid on a examined computer. In that very same room, he blasted a ruggedized Dell computer, that used to be grew to become on on the time, with water from a hose. This examine takes position for no less than Three mins, with water (from a nozzle with a 6.Three-millimeter diameter) sprayed at a system from eight.2 to nine.eight toes away.
For a second, he grew to become up the water force even upper, to turn that the system may take a couple of moments of larger force with out a flicker. In some other water examine, which lasted 10 mins, an oscillating tube with tiny spray holes soaked a computer from in every single place.
Subsequent, when he confirmed us the large dunk tank for underwater submersion trying out, Bundrant defined that Dell discovered so much about sequential trying out with this system. At one level, a Dell Rugged pill may go immersion of one meter for 30 seconds. However the system could not go that once a drop examine, so the corporate determined to not make the immersion claims.
So, in case you are questioning what makes Dell’s Rugged laptops price their worth, it isn’t simply that they are larger and heavier and that they really feel tougher. In addition they go through the type of strenuous trying out that appears to lead them to price a long-term funding.
