Toshiba "dynabook UX53 / D" is a robust 13.3-inch thin mobile notebook that can withstand diagonal drops.

Cleared robustness test compliant with US Department of Defense procurement standard "MIL-STD-810G"

The biggest feature of the dynabook UX53 / D (hereafter, UX53 / D) is its excellent robustness. In mobile notebooks, there are many products that are characterized by robustness, but UX53 / D overwhelms competing products that pass the robustness test compliant with the procurement standard "MIL-STD-810G" set by the U.S. Department of Defense. It has achieved such a robust construction.

There are 10 types of robustness tests that UX53 / D has cleared: drop, dust, altitude, high temperature, low temperature, temperature change, humidity, vibration, impact, and sunlight irradiation. Moreover, in the drop test, all the tests are much stricter than the general robustness test, such as dropping from a height of 76 cm in all 26 directions to confirm normal operation (detailed test contents). As you can see in this link).

Also, this is not the only robustness test that the UX53 / D has cleared. In addition, a 100kgf surface pressure test and a 30cc drip-proof test on the keyboard surface have been cleared, and a "high acceleration life (HALT) test" has been conducted to confirm long-term reliability. In addition, it has passed the durability test by the German certification body TÜV Rheinland, which is a third-party organization, and it is said that its excellent robustness is confirmed as well as its own test.

Such robustness is achieved by using a magnesium alloy that has both lightness and strength as the material of the housing, and by adopting a honeycomb-shaped rib "honeycomb rib structure" that enhances the strength against twists inside the top plate and palm rest. It is said that it has been realized. Actually, even if you twist the liquid crystal part or the main body with a slightly strong force, you hardly feel the weakness of the strength, and it is very reassuring. If this is the case, you should be able to carry it with confidence every day.

The main body size is about 316 x 227 x 15.9 mm (width x depth x height). In recent years, the number of mobile notebooks with a smaller LCD bezel width and a smaller footprint is increasing, and the impression is that the bezel width is wider and the footprint is slightly larger than those.

However, this size is also in consideration of robustness, and in the case of trouble when dropping, the housing is dented by the impact applied from the outside, the impact is directly transmitted to the internal board etc. and it is damaged, and in most cases it becomes impossible to start. It is said that.

Therefore, in the UX53 / D, a cushioning area is secured by intentionally giving a margin to the housing size, and even if an impact is applied to the housing due to a drop or the like, it is difficult for the impact to be directly transmitted to the internal board or the like. I'm convinced that the size of the housing in that sense.

The weight was nominally about 1,090g, and the actual measurement was 1,069g. Since the number of mobile notebooks equipped with a 13.3-inch LCD that weighs less than 1 kg has increased considerably, I don't think it's particularly light, but if it weighs a little less than 1 kg, it can be said that it is light enough to be a mobile notebook.

The body design is very simple, and you can feel the dynabook-ness. In addition, the top plate and palm rest are hairline treated and have an excellent texture. However, the overall impression was rather plain, and I felt that it was a business mobile-like design in both good and bad ways.

The front of the main body. The LCD bezel is not narrowed, and the slightly larger housing is for improving robustness. The design is simple, but the hairline treatment gives it an excellent texture. The footprint is approximately 316 x 227 mm (width x depth) on the left side of the front of the main unit.The height is 15.9 mm, which is thin enough. The weight of the bottom of the back right side was actually 1,069 g.
