Ultrabook Lenovo Carbon X1 Review

Lenovo ThinkPad X1 Carbon – this Ultrabook, which is already three times reissued known manufacturers: in 2012, 2013 and 2014. What is he so fond of customers that receive this honor? What features in this model? Read on, and we have a detailed look at all of its pros and cons.

What lies behind the new term? Ultrabooks are a relatively recent category of notebooks, which occupies a niche between light laptops and tablets. Intel has put forward clear requirements for models that claim to that title. Ultrabook should be very thin (less than 20 millimeters, or 0.8 inches), easy to work with powerful and consuming low power processor family Sandy Bridge or Ivy Bridge. It should ensure a long battery life and fast charging.

This class of models is very different from a netbook. They offer more power in the form of faster processors and more RAM, and a larger amount of space for file storage, a larger screen size and quality, and often premium design. These functions make the best ultrabooks much more expensive than most netbooks.

Lenovo ThinkPad X1 Carbon 2012 version has been implemented in strict classic combination of colors – black and dark gray, the case is made of soft-touch carbon fiber that will reduce its weight without compromising resistance to damage. Among the advantages of ultrabook must first call the powerful processor (by the standards of 2012) – he could operate at a frequency of 1.8 to 2.7 GHz during heavy load, a large amount of hard disk space – 256 GB, and as much as 8 GB of RAM. All this ensured quick work with any tasks. In addition, the battery was charged by the Lenovo X1 charger from 0 to 100% within 45 minutes and could boast a long job. Build quality, information protection features – all would be ideal in this ultrabook, if not for the screen and ports.

The latest generation of the flagship Lenovo ThinkPad X1 Carbon Ultrabook was published in 2014. Lenovo X1 Carbon 3rd generation is still focused on affluent customers, businessmen and top managers, and this is indicated not only by its cost. Appearance devaysa almost no different from his predecessors and should be verified formula – laconic colors, neat shapes and edges, a material that gives the impression of the high cost. BTW, you can select Lenovo Yoga power cord at Banggood for high quality and reasonable price.

Samsung Chromebook with an 11.6-inch Display

Although we know that the Chrome OS is still not very popular, as it did not try its developers. Still, Google, which, as it did not try to fix all their misdeeds, still does not forget about his recent defeat. Why the failure? Because as has just been shown a new computer on the Chrome software, at the heart of development, which is, as it turns out, Samsung.

The price for these products was not high, only 250 dollars. For the price, the consumer receives a small, 6-inch laptop is about 20 mm thick and weighing 1.1 kg, dual-core processor, RAM 2 GB. To enable and load the program takes less than 10 seconds. The good thing about this device is that the battery does not sit within 6 hours, i.e. does not require charging for a given amount of time. BTW, you can select the Samsung Chromebook charger at Banggood. Besides, you can easily get other computer accessories (e.g. cable holder clip) there with high quality and reasonable prices.

Memory, which is on a flash drive, up to 16 GB and can store all the information. Plus, it’s given the drive to 100 gigabytes, but only for two years, with free use. And according to developers, a small Samsung Chromebook, can play video in Full HD. Also do not forget that in this production, as in all developed, the company’s products, supported by Wi-Fi and Bluetooth, ports USB 2.0 / 3.0, HDMI connector, a slot for SD cards. In general, all characteristics are ideal, but for some reason, Google, usurped this victory. Although, all designed in the portable laptop, applies only to Samsung.

Recently, Google has too much become appropriate the merits of others. Which, apparently, and started ahead of rating and quality. And they have no choice, they do not act correctly, but unfortunately, such action will not lead to good and can end in tears.

Review of Samsung Chromebook 2

All variants of the Samsung Chromebook 2 are equipped with Wi-Fi module with support for 802.11ac, as well as the CPU used or Samsung Exynos 5 Octa, or set in our Intel Celeron configuration. Let’s see how these and other components affect the work with Chrome OS.

Construction quality more than satisfactory: a slightly pressed only the center of the keyboard and the lid, the rest of the surface of this type successfully resist deformation. Cover pleased resistant to bending, and thanks to the tight loops it does not play, even during fast typing, regardless of the opening angle (max. 135 degrees). Laptop weighs just 1.2 kg, so that its transportation does not make much effort. BTW, you can select the replacement of Samsung Chromebook power supply at Banggood. Besides, you can easily get other power supplies (e.g. 15V 5A power supply) there with high quality and reasonable prices.

Chromebook 2 is equipped with a processor, the Intel the Celeron N2840, 2 GB of RAM and eMMC-module 16 GB. Needless to say, the characteristics are very modest, but they lack the Chrome OS. By virtue of the limitation of the operating system is unpretentious, if Windows 8.1 on a similarly equipped tablets are often slow, the Chromebook 2 is almost always responds quickly. Download web pages and running applications will not cause delays.

A small amount of memory, however, can be a hindrance: five tabs from Google Maps uses almost 2GB. This does not lead to a significant slowdown of the system, but users accustomed to a couple dozen tabs open, we would still be advised to take one of the models with the Samsung Exynos 5 Octa: all of them are equipped with 4 GB of RAM.

Below are the results of various benchmarks running on our Samsung Chromebook 2. As usual, the absence of the most popular versions of the utilities for the Chrome OS browser-compels us to restrict the tests. They show that the Chromebook 2 is slightly ahead of the old Chromebook , but competing Chromebook from HP and Acer with low voltage Intel Celeron processors on the Haswell architecture or Broadwell work almost twice as fast. True, they are much more expensive.

 

How to Disassemble the Power Supply from the Laptop

Power supply is usually used for battery charging and to ensure the notebook power instead of the battery. There are situations when it is necessary to disassemble the unit power from the laptop (in most cases “whiling away” wire). To do this, at first glance, it is not easy, since all the components of the unit is very well matched and stitched.

The hardest part is cutting the first hole. To do this, take a very thin and narrow screwdriver and heat it. Then, set a screwdriver to block the seam and gently press down until you hear a click. After start moving the screwdriver along the seam until the charge is not revealed. Often there are charging that open is not easy: it is the PSU notebook Asus, Acer, HP, Dell, and others. Charging for Apple MacBook opened similarly, except that they are not glued together, and connected in a special way, but when opened and appearance suffers.

Now find the cause of malfunction, check the voltage at the output of the card. If everything is in order, then look for the problem further. Remove the metal housing, sealed-off from his board charger. Cut the rubber stopper plug. Then cut the excess part of the wires, solder the wires to the entire connector and solder it again. Power supply for laptop is now ready to work and charge the device. If carried out carefully disassemble, the unit power will not greatly damage and its appearance will remain perfect.
