Lenovo didn’t bring out slate devices

Tuesday, March 2nd, 2010

Lenovo refreshed its tablet-capable business laptop on Tuesday and made a very conscious decision not to bring out a slate device, saying customers don’t want it.

Lenovo updated its x series tablet with a new x201 model that packs Intel’s newest low-power Core i5 and i7 processors. In addition to the performance improvement that comes with the faster Core i series chips, the x201 also boasts better battery life over previous models, according to Mika Majapuro, senior worldwide product marketing manager at Lenovo.

Lenovo will stick with the tried-and-true Laptop-based convertible tablet designs and not bring out a slate device due to negative feedback from customers, an indication that Apple’s iPad may face resistance at businesses. “We of course build plastic mock-ups that we show (to customers)…we had a slate form factor,” Majapuro said. “The feedback was that for (our) customers it will not work because of the need to have (a physical) keyboard.”

The most prominent example of a pure slate device is the Apple iPad, which has a virtual keyboard. Majapuro said the response from customers to slates was a surprise. “It was amazing to me. At first I didn’t want to believe (our customers) but the keyboard was such a big need for them,” he said.

Majapuro said Lenovo even got feedback from high school kids. “These were 14-year-old kids, who, I thought, would be most willing to try a virtual keyboard but they said no, we want the physical (built-in) keyboard.”

Lenovo also announced 17-inch ThinkPad models, including the W701 and W701ds (dual screen) ThinkPad. These also come with new Intel Core i series processors.

Lithium batteries are environmental

Wednesday, February 24th, 2010

Experts believe that the market most of the use of high-capacity lithium batteries due to the different chemical composition, in the event of problems of quality, prone to explosion injury accident. And the relative safety of the nickel-metal hydride and nickel cadmium batteries.

“There will be a long time ago, lithium, lithium element is too active, it is not safe when used often in charge when burning, bursting, subsequently improved lithium-ion batteries, lithium can inhibit the added element of active components, so that to improve safety standards for lithium power and efficiency. “Guangzhou Electronic Technology professionals in Jing Lv splashed said that the current existence of Li-ion batteries due to small size, energy density, memory effect, and so obvious advantage in an increasing number of electronic product areas to be applied, however, lithium-ion Inspiron 8500 battery,Inspiron 8600 battery also has many shortcomings: a short cycle life, charging circuit complexity of the internal protection circuit of the battery and so demanding, especially for the fully sealed aluminum package, lithium ion batteries in its security the design of the protection there is a very fatal flaw.

The safety of lithium-ion battery designed to over-reliance on the protection of its internal electronic security chip, but not set the necessary physical security protective measures. In the charge and the use of the process, the event of a failure of its security chip failure, the consequences are disastrous, ranging from gas build-up occurs within the battery cell body caused by the phenomenon of up drums, heavy may occur because of abnormal cells caused by internal short circuit, etc. Battery explosion tragedy.

Mr Lu believes that nickel-metal hydride and nickel cadmium batteries to the top has a vacuum designed for the exhaust vent and the current common market, a variety of lithium-ion batteries but with the nickel-metal hydride and nickel cadmium batteries designed to very different are closed the whole package, aluminum, and its over-reliance on in-house electronic security controls to protect the chip, and does not use vent as its physical protection devices. At this point, the internal battery when the occurrence of certain physical abnormalities, or to protect the internal electronic chip failure, it also apt to shoot up because of the battery internal pressure caused by the explosion. If the lithium-ion battery to install a similar nickel-cadmium nickel-metal hydride battery vent or similar pressure cooker’s safety valve, can effectively prevent a tragedy from happening Inspiron 9200 battery,Inspiron 9300 battery.

Mr. Lu pointed out that the safe use of lithium batteries should be noted that the use of excellent quality, qualified lithium-ion battery, use of qualified supporting lithium battery charger, universal charger as far as possible to avoid the use of mobile phones, if allowed, then the safety factor as far as possible to purchase a high polymer lithium battery . In addition, the battery charging as much as possible to avoid too long.

The inventor of the battery

Tuesday, February 23rd, 2010

In the eighteenth century, the forties and fifties, power generation devices to improve the study and atmospheric electrical phenomena, has attracted wide interest physicists, 1745, Prussia Kleist lead to friction from the use of electricity quoted to the bottle with nail. When he hit a nail when the hand by a violent blow laptop battery.

May be inspired by this discovery, Leiden University Mason Brock invented in 1746 to collect the charge of “Leyden jar.” Because he saw the hard-won collection of electricity in the air very easily fade away, he wanted to find a way to save electricity. One day, he used a gun barrel suspended in the air, with the starting motor and the barrel attached, and the other from the barrel with a copper wire leads, immersed in a glass bottle filled with water, he let an aide a hand with glass bottles, Mason Brock energetically shaking from the side motors. Then his assistant accidentally in one hand and the barrel hit, he suddenly felt a strong shock, we call him up.Mason Brock then exchanged with the assistant and let assistants from motor shake his own in one hand and Shuiping Zi, the other hand touch the barrel hp-pavilion-dv4000-battery-p-44250.html”>Pavilion DV4000 battery.
In the letter, he described the results of this experiment:

“I want to tell you a novel experimental facts, however horrible, but I warn you again not to repeat the experiment anyway. … … Put the container on the right hand, I tried to use the other hand from the charge on the extraction of iron posts sparks. Suddenly, my hands were a bit big blow to the power to make my whole body shook, … … arm and the body of a sense of unspeakable terror. In a word, I thought I had life have died. ”
Although the Mason Brock unwilling to do this experiment, but he conclude: to live inside the body on the glass bottles can be saved electricity. But at that time not clear whether the role of conserving electricity is a bottle or a bottle of water, then people put the charge storage bottle called “Leyden jar”, the experiment known as the “Leyden jar experiment.” This “electric shock” phenomenon was found, creating a sensation, which greatly increased the awareness of Leyden jar concerns.

Mason Brock’s warning from the opposite effect, people engaged in a larger scale repeat of this experiment, and sometimes the experiment is simply become a fun game. People with the Leyden jar to kill the rats spark discharge performance, some people use it to point of alcohol and gunpowder. One of the most spectacular one-scale demonstrations in the French Nolette Notre Dame in Paris, before the of the. Nolette has invited the members of King Louis XV’s royal spot watch the performances. He transferred to the 700 monks, so that they can hand in hand row of the public and his party, a total length of 900 feet, about 275 meters, which is extremely spectacular. Let the first row of the monks hand Hold Leyden jar, behind the tail of the lead monk holding a Leyden jar, and then to Leyden jar from power, the results of 700 monks jumped almost the same time due to electric shock, the presence of whom who are all stunned. Nolette in a convincing tone of voice to explain the tremendous power of electricity 417066-001 , 346970-001. It soon became again later electricity used in medicine, will be generated from the electric motor through a patient’s body for the treatment of hemiplegia, neuralgia and other diseases. This treatment method has been used, until people find out the role of power after stopped.
The history of the battery cell in 1800 was primarily due to the discovery of around Volta alessandrovolta discovery of zinc and silver pieces by soaking the tissue separating the sea water or salt water can escape from the formation of current. Known as the Voltaic pile. Ruoqiang clean zinc and silver pieces were included in the lips, upper and lower side, because saliva is also acidic (like electrolyte) also produces an output voltage, so the lips will feel weak current is passed. In fact as long as between two different metals connected to the electrolyte will produce a different potential difference. johannritter was discovered in 1802 can be repeated production of rechargeable batteries. However, the original batteries are still not ideal, through the continuous improvement of up to 1860 or so, started to develop the originator of the modern battery. First of all georgeleclanchefrance in 1860 to develop carbon-zinc batteries. The battery is more easy to manufacture, and the initial wet water-based electrolyte gradually turbid with sticky paste-like manner similar to replace, so, when packed in containers, dry 』『 of the battery occurred, that is the ancestor 』『 Battery. Carbon-zinc batteries is still the most modern production of dry batteries in the battery. Lead Battery: 1860 raymond develop a lead-acid batteries, using two thin pieces of rubber sheet of lead separated, and then immersed in diluted sulfuric acid. The initial capacitance is small, then switching to lead oxide made more responsive and more efficient. Car use is still the main battery. Also accounted for the world, 60% of battery sales. In recent years, sealed lead battery more easier to use. Not only economic (cheap) and can adapt to different environments. Lead Inspiron 6400 battery,Inspiron 640m battery positive lead oxide into lead sulfate pbo2 reaction pbso4 malpractices in the negative lead is also a reaction to the formation of lead sulfate pbso4 electrolyte is dilute sulfuric acid.

Laptop Battery Maintenance and User Guide

Sunday, February 21st, 2010

A new battery from the initial use to the routine maintenance, maintenance, preservation, what do need to pay attention? The following is from the ECPOW engineers order form:

First, the initial use of newInspiron 1100 battery,Inspiron 1150 battery needs attention.
Just started using the battery, sometimes display calibration tables are not allowed to charge, or charge a long bright light, it is because the new batteries may power your notebook’s own testing procedures are not synchronized.
Of course, the use of a period of time will be automatically adjusted over, but we can also make some initial settings to achieve as soon as possible.

Way is to power off alarm, let the battery discharge optical, and then washed. Two cycles can be the specific steps are:

Start “” Settings “” Control Panel “” Power Options “” alerts
1, when the power reduced to the following level, the issue of low-battery alarm (L)
2, when the power reduced to the following level, given the acute shortage of the battery alarm (C)
All of the above items in front of two choices “step” option to remove the hooks. Let notebook has been discharged into the black. And then put two red circle, to fully activate the lithium-ion batteries to achieve synchronization with the capacity testing procedures.

It is noteworthy that this method without the use of each of the new Inspiron 1501 battery,Inspiron 1520 battery  when they you do so only in the capacity testing procedures used under the premise is not synchronized.

 Second, daily use need to pay attention to.

Li-ion battery car will exceed Ni-MH battery vehicles in several years

Wednesday, February 3rd, 2010

According to Yano Economic Research Institute predicted that hybrid electric vehicle market will continue to expand, while lithium batteries will also benefit from in 2011 began to replace nickel-metal hydride VGP-BPS2 batteries, lithium-ion is expected in 2015 rechargeable batteries in the automotive market, the proportion will rise to 15%, the market ¥ 100,000,000,000 size of a breakthrough, but by 2020 this proportion will be further raised to 30-40%, the market scale reached 2000-2600 yen.

And according to Japanese IIT predicts that the use of liquid lithium-ion battery (LiB) of the hybrid electric vehicle (HEV), plug-in hybrid electric vehicle (PHEV), a pure electric vehicle (EV) from 2009, 2010 began the introduction of relatively large number, 2012, its market has not yet reached the size of nickel-hydrogen cell vehicles, but in 2013, began to go far beyond its size Ni-MH battery car; and, from 2013 onwards, Ni-MH VGP-BPS8 battery car size of the market had been the basic fixed , almost no growth, but the lithium battery market size cars, along with the new car market in the growth of the energy gradually grow and become the market mainstream.

Prior to the relatively nickel-hydrogen cell vehicles, lithium battery vehicle safety and cost issues more prominent. At present, these problems have to get better from the technical aspects of the solution.

Such as cost, according to Golden State securities analysis, lithium batteries cost more than nickel-metal hydride batteries, lithium batteries is mainly due to previously mainly used as cathode material of lithium cobalt oxide, which are noble metals cobalt, the price is high (50 yuan / ton, the amount of 60% cobalt lithium cobalt price of more than 400,000 yuan / ton); Now lithium battery cathode materials have been gradually cheaper lithium manganese oxide and lithium iron phosphate (18-30 yuan / ton range) transition.

Although the 2010 lithium batteries cost more than nickel-metal hydride batteries, but the cost of lithium batteries is expected to begin in 2010 will be dropped from the nickel-metal hydride batteries with a considerable level, even after the cost of lithium batteries will be significantly lower than the nickel-metal hydride batteries.

Microsoft is investigating Windows7 false laptop battery issue

Tuesday, February 2nd, 2010

Many notebook users from Windows XP / Vista discovered after upgrading to Windows 7, the new system severely shorten the battery life.

Official Microsoft TechNet forums, there are users post, said he put himself in 2007 bought an HP laptop to upgrade from Windows Vista to Windows 7, but the battery life but never became a mere two hours, half an hour, but Microsoft is repeatedly promote the new system can significantly extend the battery life time. Other parts of the web forum had a similar question.

It is reported that Windows 7 is the root of the problem adds a new battery testing tool that can determine whether the battery needs to be replaced and inform the user, but in some cases, even though the battery business as usual, the system will judge whether the error that the battery has been exhausted, and recommended that users immediately replaced, and sometimes even directly shut down the system. Some users reflect the frustration that he did you are prompted to replace the old battery, but the new battery or continue to receive the same warning.

Some people say that this issue as early as Windows 7 Beta testing phase existed, but some say that the official version of RTM where phenomena. Posted by a user, said: “In the RTM version of Windows 7 prior to installing the battery, I have been normal, in my installation of all the Beta and RC versions where can persist for nearly three hours. Now, only had about 20 Windows 7 minutes to put my notebook shut. This situation is in my shift from the RC occur when the RTM. Needless to say, I have a very bad mood like everyone else. ”

Microsoft said in a statement that the problem has been known and noted, and Windows 7 to read the way the system firmware in many different types of notebook manufacturers are present. Microsoft said: “We are working with hardware partners to investigate this issue. Windows 7 with firmware information to determine whether the battery needs to be replaced. We are working with partners to find root of the problem, to obtain the necessary information and guidance and then go in (TechNet) Forum Update. ”

Microsoft also claimed that sometimes the new tool is working correctly, in other words, if it prompts you to replace the battery, it is possible your battery really has to be hung, but the chances of false positives is clearly too high.

Car lithium battery bacomes into a global R & D hot spots

Li-ion battery will become the latest low-carbon economy excitement

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the next few years, the automotive battery market is booming. “It is predicted that by 2014 the market size will expand rapidly to 2.25 trillion yen (about 24.8 billion U.S. dollars), is about 215 times in 2008.; It is d a professional market research agency Fuji, Japan Economic Research Institute has recently taken statistics Inspiron 6000 battery.

Reducing emissions and oil resources in response to the twin pressures of an increasingly scarce in most countries, the development of new energy vehicles will be seen as a revitalization of the domestic auto industry and energy savings of how the most important, while reducing the more stressful, and the United States for promoting the flagship development of new energy vehicles. Recently, China and the United States issued the “Joint Declaration”, said that both parties will be launched at the initiative of the U.S. electric car, the two countries in years to come, more 1 million electric cars used.

In China, in March last year, “issued by the restructuring of the automotive industry and the revitalization of planning” in the development of new energy vehicles have also developed a broad target - the next three years, China will form a plug 500,000 electric hybrid type and common hybrids Energy Qijuchanneng. In 2012, the new production vehicles, there will be 10% energy saving and new energy vehicles, vehicles with new energy should reach 500 billion output value of RMB.

Faced with such an interesting cake market, prices of domestic cars, spare parts and other upstream companies have exposure to these products to very good early position.

Compared to conventional vehicles, new energy vehicle technology gap with foreign countries do not, there is the possibility of exceeding bend over to help companies involved to increase investment in new optimism energy vehicles . Among them, the battery powering the vehicle - lithium-ion battery is a major R & D related to the Latitude D830 battery target.

It is understood that the current hybrid cars use nickel-hydride technology battery metals major, but the nickel-metal hydride battery a number of technical features such as energy density, charge and discharge rate is close to its theoretical limits. The lithium battery has an energy density, high capacity, no memory, etc., are car manufacturers and battery suppliers unanimous support of the current national focus on R & D is the lithium-ion batteries .

According to the different cathode materials, lithium batteries are cobalt oxide, lithium, lithium manganese oxide, ternary materials, and four types of lithium iron phosphate. Lithium iron phosphate is the best hybrid vehicle using lithium cathode materials. Currently, prices of cars in China introduced models in purely electric vehicles, batteries power batteries are lithium, Chery, BYD uses iron phosphate lithium.

Although China Li-ion battery production ranks third in the world, but in products, and technical level with Japan, the United States, there is a certain gap, the lithium batteries of the automobile are not yet in the industrialization of the essay. Xinhua noted that the letter and other research institutions, China’s relatively backward production facilities of battery power, many companies focus on the subject, ignoring the improvements of the manufacturing equipment . At present, China will depend mainly on the production of batteries and equipment imports expensive, which is our development of battery power vehicle is very unfavorable power batteries in mass production It should be equipment for advanced automation, the focus of advanced research. In addition, most independent research firms in China battery power and development, funding is limited, only the fundamental problems to solve cell technology is difficult to advance further. Lack of adequate communication between businesses, all want to know the circumstances of other people do not want to talk about their own experiences, there is widespread low-level study of the phenomenon of repetition.
