The first digital computers were huge, clunky machines. A single model was large enough to fill nearly half a room. In those days, it must have been hard to imagine compressing such a machine to a size small enough to fit in your lap.
So let’s take a moment and show some appreciation for the modern laptop - that you can bring it to and from the office, that you can carry it to the coffee shop, that you can take it with you on your travels.
Nowadays, many laptops are just as powerful as their desktop counterparts. They have muscle processors, stunning displays, and large storage capacities. Laptop specs have gotten so advanced that it’s too easy to forget about the principal allure of a laptop computer - portability.
If you own a laptop, you’ll probably take it out into the big wide world at some point. And if you’re going to take it out into the big wide world, it should be tough enough to withstand all that the world has to offer, namely, harsh weather and hard knocks.
HP® hasn’t forgotten that laptops must be strong in performance and durability. We design all of our laptops with durable builds, but there are a few models that stand apart from the rest. Let’s discover the three most rugged laptops from HP®.
What defines “rugged?”
According to the Merriam-Webster definition, "rugged" describes an entity strongly built, constituted, presents a severe test of ability, stamina, or resolution, or is strongly built or constituted [1]. These characteristics fit the bill for rugged HP laptops.
Liken any of our laptops to Clint Eastwood in one of his classic westerns: a lean, mean cowboy riding through the frontier with gritted teeth and hawkish eyes, unfazed by the wilderness or bandits. Rugged.
First, let’s look into what makes a laptop rugged, and then we’ll call out some of HP’s most rugged laptops for your consideration.
Here’s what could damage a laptop
Your laptop is bound to get knocked around a little bit when you transport it from point A to point B. It doesn’t matter how careful you are. When you’re moving across any environment, your laptop will experience vibrations, sudden stops, sudden drops, and collisions that could jostle the interior components.
Think about it. When your laptop is in your vehicle, the vibration of the engines will cause your computer’s internal hardware to vibrate, too. When you slide your laptop into your backpack, there’s a small collision between the computer and the fabric. Most shocks are minuscule, and you won’t think twice about them. But for that very reason, HP® computer engineers have to think about these things when designing the build and configuration of a laptop.
A laptop is full of sensitive hardware that needs to be protected as you carry it from place to place. HP® engineers must ensure that the motherboard circuitry and hardware are tightly locked into place and won’t move around too much when the laptop is in motion. The engineers must also ensure that the casing can protect the internal hardware from collisions and that nothing will pierce the casing and damage the hardware.
Weather conditions create their unique challenges, too. You may need to use your laptop in unusually hot or cold conditions. Prolonged exposure to high temperatures can cause your laptop to overheat. Prolonged exposure to low temperatures could cause your computer to freeze.
If you’re using your laptop where there’s wind, sand, or dirt, you risk small particles entering the laptop and disrupting the interior hardware. And then there’s the threat of water damage.
Our HP® engineers must design laptop casings that are enclosed enough to prevent particle entry and have enough openings to allow for proper heat ventilation. The casings need to be well insulated, but, again, they also need to ventilate interior heat. And style can never be sacrificed for durability.
To design a rugged laptop, our engineers must solve a long series of catch-22 design scenarios. They’ve triumphed time and time again.
HP’s Total Test Process
We determined the 3 most rugged HP laptops through our tried-and-true
HP® Total Test Process (TTP). The Total Test Process puts all our laptop models through a series of stress tests to ascertain their strength and durability in various environmental conditions. The tests replicate real weather and movement conditions that the laptops might encounter. They simulate the rough handling of the product over its lifespan [2].
TTP incorporates:
- 120,000 hours of rigorous, multi-tiered testing procedures
- 50,000 test steps
- 240 industry-standard hardware and software tests
We follow procedures established by the U.S. Department of Defense, using professional laboratories and standardised methods [3].
TESTING CATEGORIES
Here are the tests we perform on our laptops and what they entail. Most PC manufacturers, like HP, put their computers through 5 to 8 of these tests, sometimes more.
Dust test
The laptop is dusted with Arizona road dust for six hours while operated.
Humidity test
The laptop endures ten cycles (ten days) of temperatures being cycled between 86 ℉ and 140 ℉, with a constant humidity of 95%.
Altitude test
The laptop is under pressure that simulates an altitude of 15,000 feet (the highest altitude for military aircraft cargo).
High-temperature test
The laptop is operated while it’s exposed to high temperatures of 140℉. The laptop is also evaluated while it’s not operational under temperatures of 160℉.
Low-temperature test
The laptop is operated while it’s exposed to low temperatures of -20℉. The laptop is also evaluated while it’s not operational under temperatures of -60℉.
Temperature shock test
The laptop is tested to see if it can be operated safely after being exposed to a sudden change in temperature. Temperatures shift from 205℉ to -60℉.
Sand test
The laptop is exposed to blowing sand at 140℉ for 4.5 hours (the laptop is rotated every 90 minutes).
Explosive atmosphere test
The laptop is tested to see whether it can safely operate in fuel-air explosive atmospheres without igniting an explosion.
Freeze/thaw test
The laptop is exposed to a temperature of 14℉ for two hours.
Bench handling test
The laptop is put through bench handling, maintenance, and packaging and then evaluated afterwards.
Crash hazard test
The laptop is put in a crash simulation to ensure its hardware does not eject in such a scenario.
ESD (electrostatic discharge) test
The laptop is exposed to electrostatic discharge at 11 different points. The maximum voltage is 8,000 volts.
Vibration test
The laptop is exposed to the vibration that simulates it being placed on a U.S. highway truck for 1,000 miles.
Shock test
The laptop is exposed to shock in a variety of different positions.
Drop test
The laptop is dropped 26 times from a 30-inch height. It’s dropped on every side, angle, and edge. It’s dropped on plywood over steel over concrete.
Pass/fail criteria
The laptop is giving a passing grade when it can successfully boot up its operating system after the test.
Most rugged HP laptop overall
If we had to designate only one laptop as the “most rugged,” we’d pick this one. The
HP ZBook Studio 16” G9 Mobile Workstation PC has been highly touted for its extreme durability and reliable performance in various harsh conditions. In reality, though, many
HP ZBook models have the same durable build, like the HP ZBook Studio and HP ZBook 17. We picked this specific model because of the design of its casing.
The casing has curved and pointed edges so that when it collides with something, it’s more of a battering ram than a helpless victim. You can carry the laptop out into the wilderness, in aeroplane luggage, or the trunk of your vehicle without worry that it’s going to be dented or broken. The ZBook Studio 16” G9 passed all of its tests with flying colours.
This laptop is built to travel anywhere. Take it on the road, take it to the beach, take it camping, take it to the desert or mountains or tropics. If you frequently use your computer outside the office, you’ll love the ZBook Studio 16” G9 because it can handle many environmental and road conditions.
A big perk about this laptop (well, it’s one of the main selling points, but it’s a perk from a durability perspective) is that it’s just as strong on the inside as on the outside. It’s powered by 12th Generation Intel® Core™ i7, i9 H series processors and Intel® Iris® Xᵉ Graphics.
Most people use desktop computers to run processor-intensive programs. Still, this laptop is loaded with enough super-powered hardware to enable you to run those programs anywhere outside the office.
