ASUS touch notebooks the world's highest-selling Sony

A market research firm GFK research statistics show that, in the statistics until November 2012, the global touch notebook shipments highest Asus. Followed are Sony, Samsung, Acer and NEC.

The data show that, in the global touch screen notebook market, Asus market share of 35%, Sony 18%, Samsung 13%, Acer 12%, NEC to 9%. It is worth mentioning that the Asus touch screen in mainland China market share as high as 63%.

This reporter has learned a very close relationship, the Asus with local touch panel makers, lower product pricing for ASUS Touch rapid growth in product shipments. A large number of orders for touch screen also enhance the bargaining power of ASUS. This will form a virtuous cycle. The same time, the close cooperation of the two sides, but also provide users with a more cost-effective product selection.

The touch screen notebook orders also caused some problems for the Asus and component suppliers. Media revealed Asus 30-40 million units in the December 2012 Vivobook laptop program orders, but due to insufficient supply of the touch panel, the actual shipments to be reduced to 200,000 units.

Too the Asus Vivobook touch screen notebook users on a purchase, he chose the ASUS VivoBook S400 reason has three main points: 1, need to run Windows8 new system; 2, touch screen; 3, price with mainstream notebooks and ultra-extreme this match. So, the only commercially available spot sales ASUS VivoBook S400 fully comply with his request.

Used ASUS VivoBook S400 for some time, the users speak he is very satisfied with the Asus VivoBook S400. His friends shared the following:

ASUS VivoBook S400 touch screen feel good, feel and accordingly no less favorable than the iPad subvert the previous operating mode, the keyboard, touch screen, touchpad, mouse switching operation can enhance the efficiency of use; 2, ASUS VivoBook S400 design very thin, very convenient to carry and has a quick meet the ultra-extreme accordingly, very fast boot and load the software; 3, Asus VivoBook S400 has a high price, with Intel's third-generation Intelligent Core i3 processor start The price of 5290 yuan.

Grasp the two Main Laptop Batteries

Now more and more people use the notebook, also will appear as notes of experts, one of the main components of this lithium battery good notebook lithium batteries? Laptop lithium hp Pavilion dv9000 Series Battery? Grasp two things:

1. To appropriate current charge and discharge.

2. Minimize discharge insufficient charging or excessive discharge.

Although the battery is a consumable, lithium ion batteries are no exception. But everyone wants to own battery fine spirit of God, to age and do not rattle're finished, no one wants to own battery on the half-dead not to pull a living, has been to the edge of the two or three years, good people taste tasteless is how is it that you say is not it?

Well, get down below began to talk about batteries. To explain, confined to the lithium-ion battery.

An appropriate current charge and discharge

General literature and national standard lithium-ion battery, said the lithium-ion hp 484170-001 battery charging current should be between 0.2C to 1C. This is with the charging current of the battery capacity, such as your battery is the 4AH then is 0.2X4 = 0.8A 0.2C charging current means that the charging current should be between 0.8 to 4A. Generally, the charging current is as small as possible in the permitted range, the lithium-ion battery charging beginning of constant current charging, in my IBM R31, this current is 2.8A, equivalent to 0.7C is charging circuit control, can not set. Although no such charging indicators exceed the standard requirements, but is actually relatively large, especially when the capacity of the battery used for some time after the fall of the charging current may be more than 1C. The laptop charging users care about the length of time has become indicators, manufacturers were forced to charging current is set at such a high level.

So the first step is to reduce the charge current. I have a friend working in the lab, and a variety of equipment ranging test him. First string on the power outlet on a resistor try, the results of the current is reduced, but became intermittent charging, this is not a good thing. After trial and error, 4 ohms is an ideal value, and this time the charge current is about 0.8A, very stable. This is just the current flowing through the machine power connector on the battery charging current is estimated to be larger, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. In addition, as the hp HSTNN-LB11 Battery voltage increases, the charging current is decreased, but the decrease amount is small, less than 0.05A. In this state-of-charge, the charging circuit does not seem to be working, the battery indicator is not lit. Such as battery voltage rises to 12.6V, the charging circuit kicks in, battery trickle charge state at this time whether the series resistance is irrelevant, the charging current is controlled by the charging circuit, charging circuit automatically end after the last full charge. Throughout the charging time is about 5.5 hours, if not resistance, the charging time is about 3.5 hours.

The lithium-ion hp Pavilion DV7 series Battery is very delicate, and good charge control circuitry is required. This charging method, can reduce the charging current to extend battery life, while use of the books of the original charging circuit controls the charge, it is relatively simple to implement, just buy a power plug (that is, from the power supply into the books the kind, it is best to buy two, the latter also with a good quality) and a resistor can, pay attention to the resistance tall, after all, about 2W power consumption , otherwise the resistance will be more heat, it is best to do a constant resistance wire, almost independent of the resistance and the temperature of the resistance wire. However, the disadvantage of this approach is obvious, is not in charge, while working with books. Another charge when there will be a strange phenomenon, I omitted to write, you try to know Fortunately, this phenomenon disappeared into the trickle charge state. Charging time is not a big problem, start charging anyway, before going to sleep at night and wake up the next day and charged, of course, if you are a night owl or sleep special short time, that is another matter.

Small current charging problem solved, and now discharge problem. In fact, this is difficult, after all, the book is used to work, the discharge current with different working status different methods mentioned here is limited specifically to restore the operation of the battery capacity.

Start the machine, the power management set never to sleep (standby) and hibernation state (hibernate), and others are set to the most power-saving modes, including CPU speed, turn off the hard disk, turn off the monitor, the other in TP management program close some do not have the hardware, such as a sound card, and then open the hp ProBook 4510s Battery status display window and let it run in the foreground! ! ! Close other programs, in particular, is a screen saver and other timed run program! ! Do not use the machine, do not close the lid, and let the battery completely discharged (discharge minimum value should not be set to 0, I set 3%). Display and hard drive shut down after the discharge current is about 0.5A, which is able to achieve on my IBM R31 minimum discharge current, discharge the battery to the machine will automatically turn off after a set minimum value. Entire discharge lasted about more than four hours, depending on the battery capacity may vary, also used this time to pass sleep.

Finally, to emphasize that the above method is not dead, especially discharge ten times there time to do so can, or else even battery Why? Charging the best are charged with a small current course, if much-needed battery directly to the power plug is inserted in the notebook can be.

My battery using this approach are now charging and discharging of 14 times, the capacity has been maintained at more than 45, while the battery design capacity is 43.2 during decline, but this charge and discharge time after all restored.

At the beginning about two points, one is the appropriate charge and discharge, the second is not to discharge less than the charge, the following look at how to solve the discharge insufficient to charge:

Do not be surprised if one day BlackBerry really sell Lenovo





Lenovo CFO Wong Wai Ming, the World Economic Forum in Davos, Switzerland, yesterday, an interview with Bloomberg revealed association for RIM.

He said: "We are looking for some opportunities, RIM, there are other companies if the right opportunity comes, it favorable to our shareholders, we will not hesitate to sell." Wong Wai Ming said the association has had a chat to RIM and its cast Acts, explore merger or strategic investment. Lenovo When will decide whether the acquisition of a mobile device suppliers, Huang refused to comment. He said he noticed the recent RIM's share price rebounded very strongly.

Analysts believe that the PC market has long been at the decline of the state, if Lenovo can make use of the advantages of scale in the PC industry to the development of mobile business, not a bad idea. In fact, after the tiger sniffing in the report have already mentioned, The reason why Lenovo smartphone sales in the Chinese mainland market leaped to second place, behind Samsung, with its outstanding experience in the PC supply chain, powerful channels have a strong relationship .

A few days ago, RIM's share price rose to a new 13-month high, mainly because RIM CEO Hynes (Thorsten Heins), RIM is not possible to sell mobile phone business, the platform addition also authorized for use by other manufacturers.

RIM will next week launch new BlackBerry 10 operating system.

Bloomberg reported that Canadian Industry Minister Stephen Harper will still be regarded as the country's "crown Pearl RIM, if there is a transaction, it will provoke the scrutiny of the Canadian government.

Lenovo talk about their own interest in the RIM RIM spokesman said Manning, at this moment no new messages can be released in the strategic assessment. He said: "We continue to evaluate all possible options in order to create new opportunities, we are concerned about those cooperation than go it alone more efficient in the field, in order to ultimately maximize shareholder value."

Apple earliest homes in the next year Samsung turn Ben TSMC

Bit network (ChinaByte) January 23, 2008, analysts expect Apple may earliest at the end of next year with competitor Samsung co-operation of the processor, and the new target will be TSMC.

Analysts believe that one of the reasons for Apple to abandon Samsung switch to TSMC, TSMC's foundry is one of the few with sufficient capacity and advanced technology; Samsung, TSMC is a pure foundry may never not compete with Apple in the finished consumer electronic products market.

The problem is that TSMC when it will be Apple's big orders? This had been deeply concerned about the problem from the whole second half. TSMC's 28-nanometer chip production capacity has been current customers booking a space. Therefore, many analysts believe that Apple orders this year is unlikely.

2014 TSMC's 20-nanometer chip manufacturing business will be fully activated. Integrated electrical, Chairman and CEO Morris Chang said last Thursday, 20-nanometer chip manufacturing task is expected to be very heavy. He said: "Many customers contact us, the high demand for them on the 20-nanometer manufacturing process." Analysts believe that Apple is "many customers".

The rugged the Dell Latitude 6430u Business over most of this evaluation



Perhaps, always gives the impression of the business of electronic products are dull and serious lack of personality, but Dell Latitude 6430u is not the case. Ultra-pole of this as a business, it passed the MIL-Spec military safety standards certification, enough to face the bad environment of frequent bumpy business-friendly, stylish and slim body but also highlight the taste and style of the owner. With the Intel Core i5 processor and 128GB solid state drive capacity can efficient and expeditious completion of the user to the day-to-day tasks, powerful, professional-grade software but also to ensure the security of commercial data. Is customized according to the requirements of corporate customers, Latitude 6430u's priced at $ 1,278 (about 7943 yuan). Today, foreign technology website LaptopMag we the Dell Latitude 6430u detailed evaluation, the following is the full text of the article:

Designs

Dell Latitude 6430u sedate dark theme the aluminum screen backplane dark soft glow of reflective powder coating gives a gripping sense of security, but also to avoid the embarrassment of a fingerprint scanner. Does it feel, the entire Latitude 6430u body texture is very comfortable, and addictive.

Entire screen backplane is only the central "DELL" logo, and the lower-right corner of the three working state indicator embellishment, it is simple atmosphere. Screen connected to the base of the reinforcing steel shaft, solid workmanship and the hand light poke, the screen also no loose very stable. Latitude 6430u wrapped around the base of the silver-gray aluminum-magnesium alloy protective strip to increase body strength, but also play a modified role.

Turn on the screen, you can see the Latitude 6430u with a slightly smaller than full-size keyboard layout, above the keyboard, there is a separate mute, increase volume, decrease volume and power button, as well as a separate set of status lights. Apart from these, the top of the keyboard is also a pair of built-in speakers located place. Keyboard below the touchpad, and five independent buttons below the two belong to the touchpad, above the three to be used in conjunction with the pointing stick.

Dell Latitude 6430u weighs 4 pounds (1.81 kg), body size is 13.3 × 9 × 0.82 inches (33.78 × 22.86 2.08 cm), with most of the other of the same size over most of this comparison, slightly thick. Lenovo ThinkPad X1 Carbon weight of 3.3 pounds (1.49 kilograms); the HP Elitebook Folio 9470m weight of 3.6 pounds (1.63 kg), a volume of 13.9 × 9.1 × 0.75-inch (35.30 × 23.11 × 1.90 cm).

Durability characteristics

Used as a business machine, the Dell Latitude 6430u many durable design. Shockproof magnesium alloy protection bar to remove previously mentioned, the keyboard also has a splash liquid characteristics. As a by product of the MIL-STD-810G military security standard test, Latitude 6430u has a dust-proof, shock-proof function, and can be used under extreme temperature and altitude environment.

However, Latitude 6430u is not a three defenses device, so do not take it as a streak. In front of a number of protection measures, it still can only withstand a less dramatic impact.

Battery life

During the LAPTOP Battery Test, Latitude 6430u Wi-Fi wireless connection ongoing task of browsing its final run time of 7 hours and 7 minutes, than similar products, the average time of six hours 12 minutes excellent. Under the same test, EliteBook Folio 9470M scores close to 7 hours 4 minutes the best scores Lenovo ThinkPad X1 Carbon, 7 hours and 45 minutes. Otherwise equipped with a touch-screen Lenovo ThinkPad X1 Carbon Touch its life length of 5 hours and 52 minutes.

Epilogue

For the strong demand for mobile office professionals, Dell Latitude 6430u beautiful appearance, sturdy and durable, and the battery life is excellent, the price of $ 1,278 (about 7943 yuan) also has a great attraction. If some consumers want to get more light, better screen effect, more comfortable pointing stick, then you can consider the ThinkPad X1 Carbon price of $ 1,349 (about 8384 yuan). However, the latter not only a slightly higher price, but also the lack of VGA interface and Gigabit Ethernet port.

The notebook is expected to share the power and phone




We can use the USB cable to the phone, tablet, media player, as well as various other device charging, with the exception of the notebook is not enough. One day, however, you may also be via a USB cable to charge the laptop, because the USB Implementers Forum (USB-IF) has been used to pass a new USB current standard supports transfer up to 100W of power hp 432974-001 Battery through the USB cable. USB Implementers Forum is a non-profit development and promotion of USB technology organizations, will provide a standard transmission interface specifications. In other words, the next to go out will never be a bunch of power supply equipment upsets headache, only need a USB cable, laptops, cell phones can all handle that.

Laptop magazine to follow the people in the USB-IF at CES last week, and was fortunate to see a modified laptop, support for the latest USB power transmission system.

The coolest features of this notebook is the power hp EliteBook 8540w Battery supply at the same time through a cable to transfer data, so only need to notebook connected to the USB interface on the display, it can be powered by the display, and also be able to display pass image and video data.

Although the notebook manufacturers will likely continue to provide a long period of time dedicated to the power of the notebook, but I believe that one day you will only get a power hp ProBook 4520s Battery block and a USB cable, rather than the power block and one only for your own laptop brand the exclusive cable head. Day, you can use the same power block and notebook to charge your cell phone, tablet and other devices.

A couple of ideas whereby you get to recognize notebook computer older and also fresh

a single, begin to see the folletín amount. Almost all of the notebook computer around the fuselage and also battery power must be fixed with all the very same folletín amount, in the event the notebook battery power folletín amount and also folletín quantity of the particular web host are usually inconsistent, notebook computer more than likely substitute battery power; add-on, inside the inventory regarding international manufacturers notebook goods, the particular the particular notebook computer physique folletín amount will be steady around the notebook battery power and also wrapping to evaluate whether or not the technique is an important basis of simultaneous imports, identified in another country simultaneous notebook computer is in the region should not benefit from the warrantee.

a couple of, begin to see the safety keyhole. If you have imprinting, put by means of notebook antitheft a lock, more than likely completed original;

a few, the lower foot. If there are usually put on and also filthy, information can be used, the production brand of the particular table is just not thus filthy;

several, begin to see the chilling lover. In the event the rotor blades have a very skinny level regarding particles, make use of Regarding higher than a full week;

a few, to choose the generation time. Notebook computer manufacturing plant 90 days before remain in love with industry, must be aware about. Quickly digital revenue upgrade, should not enable any notebook to be able to strain regarding so very long inside the route.

6th, considering the keyboard. The newest notebook's computer keyboard is quite clear, although not glistening. Applied laptop keyboard the particular crevice you will have particles, many important bass speaker will probably be put on glistening;

several, begin to see the screws. This may not be to state that? Attach bull dozed? Or perhaps U-turn out and about!

7, glance at the space. Digesting renovated notebook, the particular space is usually to be able to handle just like fresh, including the tiny space involving the STOMACH area in the notebook display, including the CD-ROM push in the space, also MODEM PCMCIA credit card software inside of, if you possibly can locate fouling, it is possible to undoubtedly Concerning go down original, yet would not seal off. Just what? Furthermore located stroke notebook computer moisture resistant natural cotton egypt? I quickly questioned the way to try this?

To put it briefly, the particular notebook computer is just not a fresh equipment, you should not extend to regardless of whether creatively will be exposed. Wide open certainly not season notebook computer, to the contrary, the particular prototypes are often one of the most trustworthy notebook computer. Details unchanged package deal regarding ebooks, to get a lot more very careful id. If the collection of the main will be very careful.

The Graphene "Enter" Solar Cells



Recently, the Massachusetts Institute of Technology researchers have developed a new method for flexible graphene sheets coated nanowires. This method can be produced for a low-cost, transparent, and good flexibility of the solar cell Asus A32-F82 Battery, it is possible in the windows, roofs and other surfaces used.

This latest study, published in "Nano Letters, co-authored by postdoctoral Park comet MIT and Zhang Sheng root (phonetic), an associate professor of materials science and engineering professional Serbia Jie · Grenada Turk, as well as other eight researchers from the Massachusetts Institute of Technology.

Currently, most solar cells are made of silicon, and then made crystal silicon highly purified and cut into thin slices, prices have been relatively expensive. Many researchers are exploring the silicon substitute, such as nano-structure or a hybrid solar cell Asus A42-A6 battery, and indium tin oxide (ITO) are these new type of solar cell using a transparent electrode.

Grenada Turk said: "Currently, ITO transparent electrode material of choice, such as a touch screen smartphone but the the indium the high price of the compound, the graphene from everywhere, inexpensive carbon . "

Turk Grenada graphene may be a new alternative to ITO material. In addition to lower cost, it is well, such as good flexibility, light weight, high mechanical strength and chemical stability advantages.

Since the stability of graphite and an inert structure, to direct at the surface of pure graphene build semiconductor nanostructure without affecting its electrical properties and structure, with a higher level of challenge. Grenada Turk and his team used a series of polymer coatings to change the properties of the graphene, to enable them to adhesive zinc oxide nanowire layer, then covered on response the lightwave sulfide quantum dots or a known material polymer P3HT.

Grenada Turk said: "Despite changes, but the innate properties of graphene remains unchanged, is a composite material has a significant advantage."

The MIT team has confirmed that the electrodes were comparable in terms of efficiency devices based on graphene and ITO. In the case of covering sulfide quantum dots, graphene power conversion efficiency of 4.2%, lower than the common silicon Asus K52J Battery, but in a special purpose in the future having competitiveness.

In addition, the first author of the study, the Massachusetts Institute of Technology Department of Materials Science and Engineering postdoctoral Zhang Sheng root Unlike other temperature has continued to rise in the semiconductor, graphite electrode coating of zinc oxide nanowires can be temperature controlled at 175 degrees Celsius.

Why Remove the Laptop Security?

Introduction: With Labor Day approaching, a new round of travel peak is beginning. When everyone in the airport security, there has not been asked to remove the security measures alone laptop it? Why can not be used together with the computer bag through the X-ray screening it?

http://s3.sinaimg.cn/middle/66b631b1g79543f3cb732&690
Laptop Why separate checks?
We enjoy the convenience notebook, have to bear the inconvenience of security when the notebook. Laptops complex internal structure, easier to refit, and most of them are metal objects. Its image by the irradiation of the X-ray machine is more complicated. If there are other metal objects on the computer bag, the security staff is hard to read, easy to miss some of the dangerous goods check potential danger, and some computer bag metal accessories can also interfere with the security staff checks.
