Durabook Laptop Marketing Claims 'Destroyed'
jkwdoc writes "The crew at [H] Consumer got a hold of a Durabook sample from Twinhead and got the green light to hold Twinhead to their word about what kind of abuse the unit can withstand. Twinhead originally claimed that their unit could survive 26 drops from 29 inches. A cracked LCD and busted hard drive later, they changed their tune. Complete with video!"
Twinhead originally claimed that their unit could survive 26 drops from 29 inches. A cracked LCD and busted hard drive later, they changed their tune.
Seriously, did anyone really think that *any* notebook could take that?
The testers were fairly impressed with how well this laptop took a beating. The title of this post is pretty inaccurate.
While it certaintly looks like it didn't live up to the full expectations, the damage taken was gradual. For the most part it was "optical drive came out, system still works." I wouldn't want to see what happens to my macbook pro in the same circumstance.
No smoking sigs indoors.
On topic, forget these no name laptops that give away samples to shady review sites, Panasonic Toughbook is the real deal.

Surely a reasonable person would expect the 26 drop number to be a mean time to failure sort of number. Otherwise you are left to think: "Oh, 26 drops is no problem, but that 27th is the real doosy".
The MIL-STD-810F test, procedure IV, calls for 29 drops of the test article while in its shipping box without functional damage. Think of that as soldiers unloading a truck in a hurry. Or baggage handling at some airports.
The operational tests are much milder. Procedure I, functional shock, is 40G for 11ms, 3x on each axis, with the unit running, without any operational glitches. Think of this as in use in an off-road vehicle bouncing over rough terrain, i.e. normal military usage. Procedure VI, bench handling, is a 100mm drop test in normal orientation, power off, 4x. That's just dropping it on a table from 10cm.
Summary
Obviously, the Durabook didnt survive some of the abuse Twinhead initially claimed it should, but lets look at this in real-world terms.
If you find yourself accidentally dropping your laptop 26 times from a height of nearly three feet, you should probably see a doctor. Most of us have probably sent our laptops tumbling only once or twice. Our first Durabook survived three very gnarly drops before something broke off completely (an easily replaceable optical drive faceplate), and at least 10 drops before we started to get some significant hardware failure. It took around 20 drops for the hard drive to fail. Thats some fairly serious protection, especially since the data on that hard drive is often worth more than the laptop itself.
The second unit was more of the same. Although we saw some minor damage within the first 6 drops on both units, all of the essential hardware, including the LCD and hard drive, was still fully functional and the machines had no problem booting. This is a huge testament to the security a form factor like this can give the consumer.

So as far as hardened notebooks go, it fairs decently, but marketing's original claims were clearly out of whack with reality.

I've seen test videos and they are amazing. You can drive car over them and all that happens is the screen cracks, they are still useable. Also seen them dropped down a flight of concrete stairs and they still worked.
... back at my last job, one of my co-workers ordered a bunch of ruggedized WinCE boxes for a set of field measurements products. The units in question were supposed to survive a 4-ft drop.
One day I was walking past his office and I saw that he received the units. I stopped in, and picked up one of the units. I looked it over, and asked if these were the units in question. He replied 'yes.' I then proceeded to drop the unit I was holding on to the floor.
My colleague jumped up, yelling "what the h*ll are you doing?" I replied "the unit is supposed to be able to survive a 4-ft drop right? I wanted to see for myself."
FWIW, the unit kept on ticking....
If one wanted a "tough" notebook for field work, why not revert to that kind of form factor? Screen above the keyboard covered by thickish Plexiglas - no screen hinges to break and the screen can be thicker. All storage on a (say) 5 GB Flash ROM disc. No moving parts. USB ports or Bluetooth to connect external peripherals when needed. Slightly slower processor than top of the line for lower heat production - a fan wouldn't be needed. All powered by standardized LiIon or NiMH AA-sized batteries. You should even be able to use alkalines or NiCads in a pinch.

It is much much much harder than you think to light a magnesium-cased computer: see http://www.simson.net/hacks/cubefire.html
I dropped a dell inspiron of a roof once, and it ran fine with no damage whatsoever. granted it was in a leather laptop case(that wasn't zipped up). It rolled end over end down a steepish roof and fell about 20 feet to the ground. I was doing a site survey for wireless internet and it stayed where it was until I walked away.
Oh Crap, I'm an optimist.....
