IDC surveys show that Acer’s PC sales in the first half year increased by 17.6% to 16.09 million units, notebooks and Internet access the 1246 units were sold, an increase of 26.7%.

Foreign media report today, was originally owned by the United States Axiotron’s all “TabletMac” trademark has been transferred to Apple, and is expected to be used outside the famous tablet PCs. A few years ago, Axiotron has announced a project can be converted into Apple’s MacBook notebook Tablet PC. After transformed, MacBook keyboard and screen have been removed, but added a written touch screen, so that the elements of a Tablet PC. The product is priced at 699 U.S. dollars.

Axiotron initially “TabletMac” name to promote the product, and applied for the registered trademark. But in the past one-year period, the registered trademarks of Axiotron but never transferred to Apple, Apple became the registered trademark owners.

The industry believes that the transfer of ownership of the registered trademark does not mean that Apple will use this trademark, Apple may only be worried about “TabletMac” are registered trademarks of Apple’s official confusion. But Apple does have potential, unveiled a “TabletMac” named after the product, if so, this product is likely that the long-rumored Apple Tablet PC.

According to reports from the component manufacturers, sources said camcorder-battery-c-79_83.html”>Samsung’s access to the Internet next year, shipments are expected to go beyond this Asus, making it the world’s second-largest Netbook access to this manufacturer.

That the majority of component manufacturers, Samsung notebook shipments next year, is expected to more than 10 million, of which 700-800 million are online present. However, some manufacturers are convinced that access to the Netbook this year Samsung shipped only seven million.

ASUS Eee PC next year, shipments are expected to present the Netbook to 600 million, which makes the Samsung is expected to take the opportunity to go beyond Asustek to become the second largest Netbook sony-vgp-bps10a-b.htm”>VGP-BPS10A/B  manufacturer. Acer still will be 12 million next year, access to the Netbook continues to occupy the top spot in this shipment, but the Samsung access to this market, Acer’s strong performance will inevitably pose a great threat.

It is learned that since the focus shifted to Asus notebook business, they have access to this market next year’s investment would be reduced.

At present lithium-ion battery have become the cell phones, laptop computers and other mobile electronic devices, basic equipment supply, but also has begun to apply to light electric vehicles and hybrid electric vehicles. However, due to rapid demand growth in the cost of lithium-ion batteries become increasingly prominent, due to the improvement of energy density battery, battery safety accidents have also been reported. Lithium-ion battery industry is currently an imminent major adjustment of the structure, dynamics and energy storage cell associated with the industrialization of materials, processes and equipment to the major technological innovations direction.

Using a variety of ways to increase security

Involving the safety of the battery material, battery design, manufacture and application in many aspects, simply change the cathode material can not completely guarantee the safety of the battery. Only the main material is necessary to carefully select the anode material, electrolyte and battery separator, such as a lithium-ion battery anode materials are carbon materials, metal oxides and alloys, graphite material is still today a major lithium-ion battery anode material, However, its safety performance than the hard carbon materials, while the spinel lithium titanate anode material has a higher security. May be resistant to higher temperatures using a new electrolyte membrane and processing of flame retardants is to improve the safety of lithium-ion dell Latitude D420 battery techniques.

Affect the safety of lithium-ion batteries are a major factor in battery electrode materials, electrolytes and manufacturing processes and use conditions. A cell phone used in lithium-ion battery weighing about 20 grams, the basic requirement is that the probability of security incidents occurred less than one in a million, which is acceptable to the public the minimum standards, the reality is even more than 1/10000000 small. Electric bicycle lithium-ion battery packs used in the weight of 3 kg to 4 kg, 100 times bigger than a cell phone, pure electric cars will use 300 kg to 400 kg of batteries, as electric bus, or the weight of the battery electric trucks will be is 1500 kg and 2000 kg, even more “mobile phone” 75,000 times the ~ 100000 times. As the battery capacity increases, the possibility of a significant increase in security incidents. Therefore, the power battery made of lithium-ion batteries, it must improve its safety performance, the greater the single cell, asking for security indexes also higher. Such as the commonly used in mobile phone batteries in use lithium cobalt oxide and graphite as a lithium-ion battery anode material for the positive, the dell Y9943 battery large-scale post-licensure safety will not be guaranteed.

China started to carry out research and development lithium-ion battery electric vehicles when there have been a number of explosions and burning accidents, one of the main reason is that the use of mobile phone batteries are usually used in lithium cobalt oxide as cathode material for batteries. Then search for alternative cathode material for lithium cobalt oxide to address the security issues is the driving force-type lithium-ion battery R & D a top priority issue. China’s high-power lithium-ion battery safety issues in the “Tenth Five-Year” period, has been a better solution. Using modified lithium manganese oxide cathode materials, reduces the nature of the content of active lithium cobalt acid lithium than low. Japan’s mass-produced lithium manganese compaq laptop battery capacity of small monomer, such as publicly reported for the 3000 Tokyo Electric Power car battery for the 216 13Ah lithium manganese batteries.

Lithium iron phosphate as cathode to do a better safety

On the cathode, the lithium iron phosphate (LiFePO4) Charge-state thermal stability of high oxidation capacity of the electrolyte is low, with better security, can be used to make a larger battery. LiFePO4 theoretical capacity of 170 mAh / g, relative to the lithium metal voltage of 3.5V, made of materials, the actual reversible capacities greater than 160 mAh / g. Compared with other materials, lithium-ion in the chemical diffusion coefficient of LiFePO4 lower electronic conductivity at room temperature is far below that of other cathode materials, the need by reducing the material size, coated with conductive agent means to enhance the material properties and the realization of applications brought the defect is low density, the volume is too large and electrolyte battery usage more. The current research focus is to develop new lithium iron phosphate synthesis methods and the material was modified to improve the overall performance of lithium iron phosphate.

The first synthesis of lithium iron phosphate JB Goodenough way to solid-phase reaction. This method is simple and convenient, easy to operate, a longer cycle of disadvantage is that synthetic products were difficult to control the stability of the batch. How to heat treatment and powder processing, the process to prevent the oxidation of divalent iron is the synthesis of critical control points. There are a lot of R & D team developed the carbon-thermal reduction method, co-precipitation, hydrothermal method, spray pyrolysis method.

At present the international community can produce lithium iron phosphate enterprises Valence, A123, Phostech so. Lithium iron phosphate under way in the development of industrial enterprises are also a lot. According to the Internet survey, 80% of domestic well-known cathode materials for lithium acer battery suppliers of foreign claims that its lithium iron phosphate during development and production of related products. And the “international professional players,” contrast, from the investment in R & D intensity and time point of view, is still in its early stages.

Compared to other lithium battery material, lithium iron phosphate is still very young. Some people say that the battery used in electric tools, it was said that it would apply to electric bus batteries, the initial opening up is the need to be encouraged.

Japan in the field of lithium-ion battery has a monopoly, Sony, Sanyo Electric, Matsushita Battery, NEC and other famous companies have built large-scale lithium-ion battery production line, but most manufacturers in addition to maintaining and expanding the production of the original brand, the all use their own advantages to develop lithium-ion battery of new products. Japan’s New Sunshine Program since 1992 to start vehicle lithium-ion battery development plans, R & D funds invested over one billion U.S. dollars, access to technology and technological breakthroughs. Toyota has recently begun mass production of lithium-ion rechargeable battery, in February 2003 for the listing of a small car “Vitz” part of the model, the stability to withstand the test of the market. Hitachi, NEC, Mitsubishi and other companies producing lithium-ion travelmate battery used in electric vehicles and hybrid bulk electric vehicles, Fuji Heavy Industries, Tokyo Electric Power Design for the introduction of use of lithium manganese oxide cathode materials for lithium-ion battery electric vehicle “R1e”, fast charging mode, 15 minutes can be filled with 80% of the charge may be moving around a sub-80km. Maximum speed of 100km / h. Tokyo Electric Power in 2006 and then into 30 year R1e. In addition, since 2007 to import a total of about 3000. Overall, Japan remains the leading countries power battery technology, its power batteries and their mass production of key materials technology has matured, the performance has almost meet the demand for electric vehicles.

Market research IMSResearch pointed out that the cost of electricity more and more phone features, but the cell phone battery is limited, although many of the current solution that claims to make up for the emerging mobile phone power supply and demand imbalance, but it does not seem able to cope with this increasingly severe headache.

The research indicated that the relevant solutions to come from different angles, including new display technology, and more energy-efficient chip design and VGP-BPS2 battery chemicals new formula, each with its market potential. However: “As mobile phones increase in electricity demand, I am afraid there is no one technology can solve the problem.” IMS stresses.

“In fact, a majority of mobile phone battery is not consumed by the data received on the call, which is committed to enhancing the average revenue per user (ARPU) for mobile communications service provider is bad news; In addition, consumers are reluctant to consume for those who will only multi-function VGP-BPS2A battery pays for, so the mobile phone OEM factory faces pressure to reduce prices. “IMS Research analyst Chris Schreck said.

Schreck said that, so that mobile phone users consume more VGP-BPS2B,VGP-BPS2C battery power for two main reasons: “First, consumers to mobile phone doing the former will not be doing more, mobile data and applications used in the past few years show explosive growth. Second, the function is now included in mobile phones, let alone those who will come out, and they will consume more power than ever before; for example, pestle force a faster speed, higher data throughput, and more vivid display screens. ”

He pointed out that even the industry’s highest-capacity 1500mAh battery, they can only let smart phone users to use 6 hours; IMS estimates that smart phone users on the average annual growth in electricity demand 15%, and this power imbalance between supply and demand situation will become more serious.

Dell’s notebooks are divided into two major consumer and commercial product lines, each of the following product lines subdivided into several series. Their difference is the appearance of a more personalized household notebook fashion, but also a variety of shell colors and patterns to choose from. The appearance of commercial laptops are more mature and more stable, more suitable for access to conference rooms and other serious sites;, of course, some of the details of the high-end models will also be more sophisticated workmanship.
Home Models

Household models have been the two main seriesdell Inspiron 1720 battery and XPS, which targeted at mainstream users Inspiron and XPS is targeted at gamers. But with the fast-growing consumer market, Dell’s consumer models will soon be subdivided into three series, an increase of one, called Studio, in high-end consumer brand.

At the same time, XPS of roles have also changed gradually from the fever-type dell Inspiron 1721 battery into a high-end home game type, but will PC gaming market is entrusted to the newly added Alienware series (Note: Dell acquired Alienware in 2006 companies) .

Business Models

In the commercial field, Dell has had two series: Latitude and Precision, respectively, located in medium and large enterprises, as well as government, educational and medical institutions. But with the SME and SOHO owners of the blossom everywhere, Dell added an affordable low-end business models: Vostro series.

Of these three business series, we can be so understood:

Vostro stressed that cost-effective, the same limited budget was a lot of consumers favor the individual can therefore be seen as a range between commercial and household products.

Latitude is the most competitive in the mainstream business models, in durability, security, battery life, connectivity and remote management, etc., are fully taken into account the diverse needs of business people.

Precision is a mobile workstation, providing superior application performance and world-class scalability, mainly used in intensive graphic design, film and television special effects production and so require robust performance, areas of expertise.

If you want to buy a stylish, beautiful home laptop, then we recommend the Inspiron series, they have a variety of colored shells for your selection and the price is very affordable, such as the dell Inspiron 1420 battery and so on.

If you are a white-collar workers, pay more attention to books portability, stability and ease of use, it is best to choose in the Latitude series. Recently new E series Latitude is very good, such as a 12.1-inch E4200 or a 14.1-inch E6400 and so on.

● Dell laptop model naming

    Dell notebook computers can be divided into: household products and commercial products. Among them, household products, including economics Inspiron series models, Studio series of audio-visual entertainment, and XPS series gaming models class models; Vostro series of commercial products include models economics, Latitude series of safe and reliable class models, and Precision series of workstation class machines type.

Most home and part of Dell’s notebook business notebook models naming rules are relatively simple, basically by “brand name”, “family name”, “screen size”, “the first of several generations of products” and “configuration code” form.

    For example: Dell Vostro1310 (S520194CN). Among them, “Dell” is a brand name; “Vostro” that this product of an economic class business models; “13″ indicates that this product uses a 13-inch screen design; “10″ indicates that all of these two numbers less than 10 products no its new, all of which more than 10 double-digit than its new products; and finally a set of brackets of letters and numbers is the configuration of this product code, as long as the visit Dell’s official website you can find out the corresponding configuration.

    Finally, we can conclude: Dell Vostro1310 (S520194CN) is a 13-inch screen designed for the economy class business notebooks.

Some time ago APPLE, DELL, SONY, HP and other international well-known PC giants have emerged in the notebook  battery recall problems and the original? Today I would like to extend the topic to a number of laptop battery knowledge to share with you?

Why do books The more you use the dell Inspiron 1501 battery power consumption less? Why do battery calibration feature makes capacity to restore part? How is the correct battery charger? All this from the start with the calculation of battery power.

Whether it has been eliminated nickel-metal hydride batteries, now used in lithium-ion battery, or not commonly lithium polymer batteries, or even tomorrow’s stars of the silver-zinc batteries, are the equivalent of a warehouse storing electricity, the difference is their access to library the way, the storage capacity only. In the notebook computer batteries, as well as a large responsible for managing these batteries housekeeper - power computing chips, which is the management of dell Inspiron 1520 battery, computing power, is responsible for charging and discharging of the “responsible person.”
In the measurement of battery technology, there are four kinds of common method, but not books of different brands of batteries using only one method of calculating power consumption are usually several ways to use an integrated, in one of the main method of calculating the rest of the calculation means to achieve the power-assisted calculation, Management. The first is the open circuit voltage measurement method, this method is by measuring the battery voltage in the stationary state values to calculate the remaining battery capacity, but because of stationary lithium-ion battery voltage and remaining capacity of the relationship between the non-linear, Therefore, this method is not an accurate measurement of the value of the vast majority of cell phone batteries have adopted this method of calculation; the second is called Coulomb’s method of calculation, the method is by measuring the dell Inspiron 1521 battery charge and discharge current, the current value and time value of the After the product is calculated by integrating the batteries into the battery charge and the release of electricity, Coulomb’s method of calculation is a more accurate method of calculating power; third is to impedance measurement method, it is by measuring the resistance within the battery get the battery remaining capacity value; The fourth is a comprehensive look-up table method, by setting a related table, the voltage, current, temperature and other parameters input, you can check the battery’s remaining capacity to be.
Thus, apart from the internal structure of the battery batteries, there are management chip, the chip contains one or two of them measuring method of calculating capacity batteries, and a set of charge and discharge protection circuit. Among the notebooks in the system, through the driver interface access to this chip, and then set the dell Inspiron 1525 battery management.
So, why the battery would be more you use less electricity, but the implementation of the correction function can restore the battery capacity of a part of it? Laptop batteries are generally the so-called six-pin power, 4-pin power, refers to the number of battery cells within the batteries. So many batteries together, that is, the less electricity more you use the fundamental reasons: batteries and the batteries between the quality of discharge can not be exactly the same level, such as discharge, in which a substantial reduction in power batteries, In order to maintain voltage stability, battery management chip will follow “casks principle”, according to the worst of that energy-saving core to charge protection, battery charge will naturally decline, the impact is even more than the battery irreversible Institute of Chemical Physics change.
Battery calibration function is to balance the multiple batteries, the battery because of their resistance can not be completely consistent, the dell Inspiron 1526 battery will be great resistance bear strong current, leading to their own consumption more than other batteries, but also easier to wear and tear, therefore, on a regular basis to do the battery calibration is necessary - so as to balance the burden of multi-cell “work”, thus extending the overall life expectancy.

Because of the portability of notebooks will be subject to everyone’s favorite, but if a laptop is not a high-quality sony VGP-BPS2 battery, laptop can not guarantee a stable long hours of work, use the laptop must have an external laptop power supply, then the laptop will lose its own significance. But the batteries are consumable items, generally able to stabilize working hours in a year or so, then there may be “sudden die-off.” If you are planning to buy laptop computers, laptop battery would need to do a physical examination in order to detect the battery problems.

Measured with the system program

Using Windows XP built-in program can view the battery status and estimated life. First battery is fully charged, then unplug the laptop power adapter. Into the “Control Panel”, open the “Power Options”, see “Power Table” option in the remaining sony VGP-BPS2A battery power, when the program is estimated based on the current operation can also use the battery time, click on the “batteries detailed information” also can see that the battery type, manufacturer, and other relevant information. However, this method to test the results of relatively simple, and because the operation of the different circumstances there will be differences in power consumption, so the credibility of the results of such tests was not high.

Using specialized software testing

There are devoted to the sony VGP-BPS2B battery test software, using these software testing information obtained should be of degree higher than the system test, so there are USB flash drives friends, may wish to buy second-hand notebook to bring these professional software counterparts. 1. Battery Mon “Battery Mon” is a shareware, the registration can be used prior to 30 days. “Battery Mon” can reflect the battery information, you can record the battery discharge curve is smooth, but also based on the actual rate of decline in consumption is estimated that the use of battery time, and the built-in standard time, and software to make comparison. And the relatively short test time. Step 1 First, the battery is fully charged, and then run the “Battery Mon” and unplug the external power supply. Step 2 Click “Start” after, “Battery Mon” to start recording the sony VGP-BPS2C battery capacity decline curve. About 2 ~ 10 minutes after electricity will be basically depicts the decline curve, when in the “Comparison Rate” and you select a power curve of the measured tilt the closest standard curve, so that you can generally know how long the battery will be able to use. Tips click on the bottom left corner of the “Battery Info” button, you can view the battery details. Although the “Battey Mon” to provide estimates of the use of battery time, but this time is real time in accordance with the current drop in computing power, so that testing methodology is not sufficiently rigorous, but it is simple and convenient operation, suitable for beginners.

Notebooks in their daily working life is becoming increasingly popular, while the right to use laptop has not been valued by most people. Perhaps inadvertently use a little trick on your laptop will produce a greater or lesser impact. Well, today we will look at it, in the end what are the bad habits has been neglected by us.
1. A dangerous use of sitting

There are many friends have heard of, using laptop easily lead to cervical disease, but it is not alarmist talk. Due to the use of desktop notebook confidential than usual much smaller on the desktop, not high enough, which led to posture is not correct, over time you can easily tired.

Nevertheless, we still have to continue to work, the notebook is very obvious advantages and disadvantages. With the laptop can not let us back to the era of desktop bar.

Editor believes that the most simple method is to find a dell Inspiron E1405 battery docking station base, that is, the heat can be easily notebook, you can also be an extension of USB, you can also adjust the notebook into a proper perspective.

   Of course, if my friends silver enough, you can also automatically adjust the screen to a PC with a notebook.

In short, enjoy the high-tech, we should also pay attention to our posture, maintaining a good body is the most important.

2. Laptop a long time to play the game

    Although the editor is also a gaming clan, but it did not suggest that you long-term use laptop to play games. As a portable computer for the greatest advantage, notebook design itself is not for the purpose of the game, but for better dell Inspiron E1505 battery and more convenient to conduct office and simple entertainment, although with the development of technology, and now the notebook already reached a certain the standard of the game, but the long-term use laptop play games there are still many defects.

  Take the keyboard, the notebook’s keyboard than the desktop confidential small, key-way short hand than the desktop keyboard is also a lot worse. There are many friends to play the game there is a fault when playing to the rise of strong percussion like the keyboard, especially the Enter key, are the most susceptible to “destroy” the site, which will lead to early retirement notebook keyboard. In such cases, editorial suggestions you can use an external keyboard.

   In addition, the laptop screen, the principle is used hidden in the lamp to illuminate the panel, while the lamp life is also very limited, and play the game, the time unknowingly passed on the notebook is difficult to get a break. But relative to the desktop, the laptop’s small screen for gamers, not habits, bad eyes, so laptop is best used for office, if you must buy play games, then buy big editorial suggestions Screen book, it will feel closer to the desktop, but also more likely to be accepted gamers.

3. To buy low-quality notebook bag

There are many friends to buy laptop Jiugen was released after a decade of blood, as are no longer willing to pay a hundred dollars to buy a good laptop bag, in fact, it is very wrong, and buy a good present even more good it should be protected.

    For the newly purchased laptop, its screen, in particular, is very fragile, so choose a good laptop bag is very necessary. After all, for most notebook computers is that they were born to be brought brought in the appropriate laptop bag naturally give their most intimate protection. This is for a new dell Inspiron E1705 battery users, perhaps more should be noted that not all laptops first wife of the package are really appropriate.

  And general office package is different from a truly well-designed notebook computer bag should first have enough strength and protection of the four sides of insulation layer, in order to prop up a laptop safe and comfortable “love nest.” Ordinary office packages often due to too much room and soft frame design, outsiders can not effectively isolate the backlog, and collision. Second, it should have a reasonable accessory compartment Bureau of the design, such as power supply should be placed in the notebook computer compartment adjacent to the side in order to avoid being accidentally squeezed the power plug when the notebook LCD screen scratched. Meanwhile, the laptop computer bag should also have some waterproof capability.

4: touch screen

Whether it is CRT or LCD is not touch, especially for the more fragile the notebook screen, the more so. Computer in the course of the surface components will be a large number of electrostatic charge accumulation. The most typical is the display after use hands to touch the display screen will be dramatic phenomenon of electrostatic discharge, electrostatic discharge may damage the display, particularly the vulnerable LCD screen.

   For the newly purchased laptop, its screen is very fragile due to, manufacturers tend to paste the screen outside the layer of protective film in order to achieve the purpose of protecting the screen.

    For the intimate details of the user, you can also look for some screen protection film and make their own decorative plastic paste-like foil material, such as easy to wear attached to Satisfy the location to better care of your love dell Latitude D610 battery . Similar design, we attach great importance such as Sony and some other laptops using the details above can also be seen. In actual use, we recommend that you try not to take watches, bracelets and other items to use laptops, because it is very easy to inadvertently, severe wear wrist rest, giving laptops shed Daodao scars.

The more and more laptops into our lives, while the notebook notebook battery is the most critical components. Then for printing in a laptop battery casing on the meaning of those values, you know how much? Join us take a look at Bar!

3. Rated Voltage (Nominal Voltage)
General FAQ for 10.8V (11.1V) or 14.4V. If lithium-ion dell Inspiron 6400 battery, for example, we all know, a lithium-ion battery voltage of 3.6V, which of course, need not reach the voltage notebook, so commonly used in series approach. If the rated voltage is 10. V, it is a series of three, four series voltage becomes 14.4V, but some of the secondary battery in the factory calibration of single-cell lithium-ion battery voltage is 3.7V, so the voltage to string together three to 11. 1V. If 1.2V Ni-MH battery, then the 9 series single cell to 10.8V, in order to achieve the laptop work required operating voltage.
  4. Rated Capacity (Nominal Capacity):
In general? Single Ni-MH battery capacity than the lithium-ion batteries large, a 18650-capacity Ni-MH battery can be achieved between 4200 ~ 4500mAh, while the 18650 lithium-ion batteries commonly used in a single section of the storage capacity of 1500 ~ 2000mAh between, so if laptop battery is a nickel-metal hydride batteries used in, as long as the battery in series to improve the battery voltage on it. The lithium-ion batteries in the battery manufacturer’s technological gaps between different Sony laptop battery such as the use of lithium-ion batteries, commonly used three parallel, to increase battery capacity, three parallel can be achieved in general between 4500 ~ 6000mAh.
5. Battery Notice:
Generally above the battery would be limited use of environmental labels, use the Notes, as well as battery recycling label.
