HP EliteBook 6930p Laptop

As the 3G era, a new era of mobile commerce for all of us before the show now - the wireless network coverage will be more comprehensive, wireless data transmission will be more rapid, and wireless-based business applications will become more abundant, HP F2024A notebook products will provide greater space for development. Mobile computing products as the best representatives of notebook products that will help business elite even more rapid, and convenient to carry out business process, to experience the charm of the era of mobile commerce.
However, notebook computers let bad business elite endurance capacity of the mobile commerce greatly reduced, leading to their true desire to be mobile commerce hanging clouds - the majority of laptop battery life will be in 3,4 hours, and then can only be long until about 7-8 hours, which is almost 24 hours a day working in the business elite is far from enough, many times, they had to stop their work, simply because the notebook battery life a serious shortage of capacity.
hp OMNIBOOK XE4 SERIES Battery are often the face of such helplessness and embarrassment: always nervous at the airport to the memorandum written more in order to charge the notebook before the completion of all work; always at every meeting of the enterprise, and his colleagues must fight get a limited number of electrical outlets; in Starbucks, the crazy looking at the other outlet to occupy the elite, I do not know is the scramble to join the ranks of power outlet or carry forward the grace to give up Jack, but no electricity will soon have to face the notebook trance; in customer sales proposal before the demonstration, on the best part of the upcoming show, the notebook because of no electricity and very annoyed ... ...
It can be said that at present most of the notebook product is not for the era of mobile commerce and prepare battery life is poor ability to lead the business elite in the use of notebook hard time, they can not use all-weather notebook mobile office and commercial business can not quickly understand the relevant business information, more timely information for business, according to the latest deal - in the current information age, almost the speed of these elites was a key factor in winning business, the capacity of notebook battery life short board to enable them to compete in and the peer can not be one step ahead to take the lead in customer recognition, it can be said that Hp Omnibook 2100 Battery have not been touched on the real era of mobile commerce.
It also makes business elite notebook battery life of the ability to issue the most urgent call of life they expect to increase capacity so that business applications notebook everywhere and at all times to make it easier, more convenient, more freedom to carry out business applications experience, truly open era of mobile commerce.
Leadership-based manufacturers have such a capacity, they are always ancestors step from sharp changes in market demand was found to change the user, the real from the user point of view, combined with innovative technology to provide products that meet customer needs. For notebook users demand for high-endurance, many companies take a different means to achieve, such as the use of lower-power processors, improving performance per watt to reduce the processor power to achieve energy-saving; or to use SSD drives, the use of abandon the past practice of mechanical hard drive to save electricity; the company also provides a multi-core battery, try to provide more electricity supply to the excellent performance of battery life ... ... the positive efforts of manufacturers also play some effect, but its endurance capacity is still maintained at about 10 hours to enable the business user satisfaction. In their view, there is no Hp Pavilion zv5200 battery life of notebook products with strong capabilities, the so-called mobile commerce experience more like a real mobile commerce from the distance they always have.
The emergence of HP EliteBook 6930p business elite closer with the real distance between the mobile business - a combination of this innovative technology, Hewlett-Packard notebook computers up to 24 hours to achieve the ultra-long range capability, so that business users really feel the most mobile business of fun.
In order to achieve this capacity, Hewlett-Packard introduced the first 12-cell battery, which on behalf of multi-core design of the lithium batteries have more power batteries, which means that the Hp f2024a battery will have a greater capacity. HP is also the first use of 12-cell battery manufacturers, she embodies the real needs of business users keen understanding and respect; Secondly, HP EliteBook 6930p using the industry-leading LED backlit LCD screen. This screen will not only than that of ordinary liquid crystal display better results, but also more energy-efficient, higher service life of up to more than 100,000 hours; third, HP EliteBook 6930p using the SSD hard drive technology, energy-efficient than the regular hard drive about 7%. In addition, this product also introduces the latest Intel graphics driver has been HP BIOS, a more subtle level, from software to achieve savings in battery power.
It can be said that, HP EliteBook 6930p emergence of truly "mobile commerce" has become possible. HP EliteBook 6930p boot exclusive 24-hour support and without charging the high capacity battery, a truly all-weather use, while Hewlett-Packard exclusive global innovation and technology, to control power consumption in Hp F4809A battery and advanced energy-saving body of the play to extreme, these are all in the embodiment of the HP from the user's needs, with a wealth of innovative features users demand the best fit of the product design concept.
At the same time, the business elite, the 24-hour life for the HP EliteBook 6930p business elite more relaxed, more convenient and experience the freedom of business applications, and its ability to weather life mobile commerce bring a qualitative leap, so the real point bright era of mobile commerce.

Notebook batteries

The use of rechargeable laptop battery is the relative advantage of one of the desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is a nickel-cadmium battery (NiCd), but the Hp F2024B batteries have a "memory effect", each charge to be discharged, very easy to use, and soon they were nickel-metal hydride battery (NiMH) replaced, NiMH not "memory effect", and the weight per unit to 10 percent more electricity. At present, the most commonly used battery is lithium-ion battery (Li-Ion), it has no "memory effect" compared with NiMH, receive more weight per unit of electricity, the price twice as high than the NiMH. In the same weight, the use of the three longer than the battery is 1:1.2:1.9. There is also a battery called polymers, very high capacity, small size, the majority used in Apple Computer.
At present, the use of notebook computer batteries in three main categories: 1. Ni-Cr battery, 2. Ni-MH battery, 3. Lithium batteries; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, lithium LI.
Purchase or replace the laptop battery when, for many users, the "Hp F4812A batteries" may be unfamiliar. First statement, batteries and battery are the two concepts. A battery is a number slightly larger than the thumb, cylindrical, about 7-8 cm, voltage of 3.6v small units, it is called professional called 18650, Sanyo and Samsung is the largest producer. Batteries , like a small battery, the combination of tandem, that is, we can see the battery. Then talk about how to judge the battery is the core of a few:
One way: unplug the battery number of contacts to see him, there are several that several of the core. But this is the "Minister" approach. We take a look at "Cao Chong" is how, "said the elephant" of: take a look at the number of your battery v nominal, such as 14.4v, and then divided by 3.6 to be 4, it proved to be in series with the battery 4. And then take a look at the capacity of the battery block, for example, 4400mAh, then proved to be the two groups mentioned above batteries in series, because the small battery capacity of 2000-2200mAh, or even more, and together the two groups can be reached 4400mAh. According to the two judgments, then the battery is 4 × 2 = 8 cores.
Composition notebook battery
Notebook batteries by the case, circuit board components and Sony VGP-BPS3batteries are lithium-ion battery. It is generally talking about batteries means the Sony Vgp-bps2 battery is the number of batteries, mAh refers to the capacity of notebook batteries.
The main circuit board by the protection circuit (or the second protection circuit), as well as the capacity of the two parts of the circuit composed of the instructions on the laptop battery charge and discharge management and safety.
Notebook battery standby time of major decisions by the mAh value. Under normal circumstances, a few more batteries, mAh value the greater the longer standby time. Notebook battery life mainly by the number of charge-discharge measurement, the quality of the products are generally qualified for 500-600 times. Therefore, the effective use of laptop batteries for 2 years, will expire aging batteries, standby time the impact of the drastic drop in the mobility of notebook computers.

Experts solve the five major notebook troubles


To express appreciation of the vast numbers of users has been the support of the World network, we focused on the use of notebook users encountered some trouble, go to the relevant funding body of the laptop experts, selected by everyone experiencing the five issues, to the vast number of users friends supporting ideas.
1, friends, Mr. Wang is an electrical engineer job, use of the Acer Aspire 1680 Battery is the Haier T61, as reflected in his notebook battery life issue is a comparatively short time.
Expert advice: the same notebook batteries are consumable items, and many manufacturers in the promotional campaign that notebook battery in case power is still able to support more than four hours to run, but in fact in power, the battery life and user operation There are a lot of the relationship between the procedures, if only to see movies, running a number of relatively simple procedures, life would be a relatively long time point. And if it is to play games or use some of the design of large-scale software, the general can only maintain the 1 - 2 hours.
2, and some Pavilion ZV6000 battery users reflect the noise, always use the time to hear the voices of a number of hula hula.
Expert advice: have a notebook noise usually comes from fans. The size of the Pavilion DV6000 battery noise is a manifestation of CPU power. Support needed for the operation of CPU heat dissipation. If it is not the cause of the accident, the general noise makers in the design will take into account the time. If it is the impact of the use of after-sales service can help find a solution, or feedback to the manufacturers, should be a good solution.
3, Wu friends, at school and university students. Reflected in the quarters to use the computer, always feeling hot feeling like notebook, notebooks have been asked is this the case of heat, will have damage to the notebook.
Expert advice: the issue of laptop cooling fans has been a vast number of notebook issues of concern, although the manufacturers have been addressing this problem, but long-lasting heat is always difficult to eliminate, so it certainly has been hot on the notebook itself, the other hardware damage, if it is a very good hostel there is no thermal environment, it is recommended in hot weather should not Win
Line the procedure is too large, you can buy in the shops a number of notebook accessories notebook cooling base, the general base are embedded heat 1 - 3 small fans, those fans on the notebook's battery, as well as better machine than the heat to help, so that the relative protection in good books, but also to maximize the use does not affect users.
4, Mr. Zhang users engaged in management occupations, the use of the notebook is a Dell Inspiron 6400 Battery, in the use of the boot process more slowly, so the notebook has been suspected to be not a problem.
Expert advice: slow boot laptop, the main boot may be more start-up items, you can type in the system between the start run command to start some unnecessary to ban it. Or some system software, such as optimization of the master, the start of clean-up look. Many notebooks now are used in Vista system, the system in a notebook because of their more intelligent behavior, the corresponding detection of more and more, it is relatively slow boot normal, with optimization of the master, to some unnecessary after the start of the prohibition, Battery for HP Pavilion DV8000 will start to upgrade the speed of a corresponding.
5, In addition, some users reflect the notebook with the Logitech keyboard is not compatible with some problems. This is I believe we are also concerned about the following, we will look at the recommendations of experts:
Expert advice: You can not use is normal, you use the USB interface keyboard on the much more convenient, but you are using a switch Sony PCGA-BP2NX interface, use the notebook keyboard interface is used can not be transferred, this movement is to interface the Question. Such circumstances there is no other method can only say that to another level is the change in interface or USB keyboard?? If it is not compatible, you can contact Logitech telephone companies to allow experts to answer the case.

2009 analysis of global thin-film battery status and prospects

In recent years, the photovoltaic industry has become the world's economy one of the hottest. Solar photovoltaic system as the core, with the climax of the rise of industrial investment, it is natural that the development ushered in the spring. According to the consultant for the latest release of "2009-2012 China Solar Photovoltaic Industry Analysis and Forecast of Investment Report" shows that more than 130 world countries into wider application of the upsurge of solar cells, of which more than 90 countries is being carried out large-scale research and development of solar cells, the active production of new products related to energy conservation. 2007 global solar cell production reached 3436MW, over 56 percent growth in 2006, 2008 global solar cell production up to 6850MW, growth rate of nearly 100%.

Solar cells based on different materials, solar cells can be divided into: silicon solar cells, multi-compounds, such as thin-film solar cells. Among them, the silicon solar cell is the most mature development, in the dominant applications. However, as in the past few years, the international spot price of polysilicon soaring, once in 2005 from the 35 U.S. dollars / kg up to 2008 of 480 U.S. dollars / kg, so the low price of thin-film batteries have been developed rapidly.

The industry has been estimated that within the next few years if the thin-film battery materials in the conversion rate and the demand for non-technical aspects of a breakthrough, it will soon be submerged in the sea of silicon cells.

Thin-film batteries for another bad news is that the international spot prices of silicon raw materials are still down, the U.S. companies such as Dow Corning has announced that the future price of polysilicon in the 40-50 dollar / kg more reasonable. Polysilicon raw materials in such a price, the price of crystalline silicon cells are close to thin-film batteries, thin film batteries, low-cost survival "trump card" no longer exists, the prospects will be extremely bleak.

It was also very optimistic about the prospects for thin-film batteries. Latest world's largest thin-film silicon solar cells photovoltaic Xinao said, "This is not to say more than 10% conversion rate on the more competitive, but in different application fields the question of who is more advantage. Thin-film and crystalline silicon applications are different, the conversion efficiency of crystalline silicon high, the use of small size, with the roof edge is. But from the perspective of customers, they are most concerned about price or system, such as the construction of large-scale power plant, the thin-film battery more There are advantages, because the area, the system price will be low. In addition, building integrated photovoltaic doing so, thin-film batteries have a better advantage. "

Leading global manufacturer of thin-film solar market trends to expand, it seems to give the industry confidence greatly. For consultants in the research department of the energy industry data show that in 2008 reached an annual production capacity of 503MW, in one fell swoop into the second position of the industry, the U.S. thin-film solar maker First Solar did not stop the pace of expansion, in 2009 the company wants to double production capacity to significantly 1GW, and this figure is expected to surpass Germany's Q-Cells, a new industry leader. First Solar's expansion was so rapid pace, with the cost advantages are inseparable. 2008 No. 4 of the First Solar-quarter average cost of production has been reduced to 0.98 U.S. dollars per watt, is the world's first production cost is lower than 1 U.S. dollars per watt of solar energy companies.

Consultant in the energy industry analyst for that the future of thin-film laptop battery, in the end is ashes in fetal life or die? Currently not final word, no one can predict the future of technology breakthroughs to what extent, it can not jump to conclusions. However, it can be predicted that the global PV market size, and not with the crystalline silicon thin-film "Game" and the growth rate slowed down to the solar photovoltaic industry to represent the future will still be the bright spot in the global investment.
