“Ultrabook. An autopsy showed "or" Make your life easier "

Although I have been working on ultrabooks for several months, I first saw him only recently.
(Yes, you understood correctly - this is the 21st century, remote access for which the ultrabook is no different from a regular computer. You just need to send a letter to a colleague physically close to ultrabook asking you to run your program there and send the result. )
Accordingly, I was not interested technical specifications of the ultrabook, and its physical parameters. And they almost failed. The ultrabook turned out to be really thin, so that you can hide it under a sheet of paper, and even, if necessary, lay books for it (not electronic).
But the weight of the device exceeded expectations. Yes, the ultrabook is lightweight. But, alas, not ultra-light. My Asus Zenbook UX31E (as, incidentally, other models, includingLenovo IdeaPad U300s and Dell XPS 13 ) weighs 1.3 kg.
More precisely, weighed. We managed to reduce its weight by almost 500g!

In general, I wonder what exactly in ultrabook gives the main weight gain? It’s definitely not a processor, it’s very light (by the way, I’ll notice that the specifications of the processors indicate their sizes, but not their weight). Boards? Battery? Screen with housing? Let's get a look.

Today, with the help of rozboris and his (from) personal screwdriver, we disassembled the Asus Zenbook UX31E :





Inside we found:
A processor with an elegant cooler, ssd, a large battery and small speakers:




But the main surprise is the inside of the bottom case cover. Four metal plates were glued to it, easily detachable from the case with a knife.

Unscrew the battery.


And we find an already familiar record under it:


We take it out, gently prying it with a screwdriver (a red spot remains in its place) and close the battery:

Putting the ultrabook back, as it was, only now is easier - we took it out of it five metal plates!



Electronic scales in the dining room of our office show that the weight of the extracted excess parts is about 490g.
This is quite significant for those who constantly carry an ultrabook with them.

Why do we need these things? Of course, at once there is a desire to blame manufacturers of ultrabooks for an unfair, albeit witty marketing move: in the next generation of their products, they simply remove unnecessary pieces of iron and triumphantly announce that ultrabooks have become a pound easier!

But wait with the charges. In fact, the purpose of these pieces is different. It turns out that many users from the focus group, who tested the experimental models of ultrabooks, complained that when working outdoors their devices simply blow off the wind. To solve this problem, weights were added to the design.
But, if you do not plan to work often “in the open air” and don’t think that a real solid device for real aesthetes should be difficult, then it’s clearly worth getting rid of the actual weight of a bottle of water and making your life easier.
