In notebook computers, Pavilion DV8000 battery is a love-hate component, it gives the mobile use of notebook computers the ability to continue to work at every turn but a few days compared to a week or even mobile phones and MD, notebook battery time remains a tooth If the cell phone battery can only use eight hours, people would be reviled, but it results in the notebook PC which is the pride of the best, to say the development of notebook computers in the slowest parts, in addition to the keyboard should turn the battery

That there is such a joke: Intel’s investment and technology through participation in support of the new battery technology, “For us, the lithium battery in the 1990s has been good enough,” director of marketing for Intel’s mobile platforms, said Mooly Eden, “Battery Improvement of teens just like the relationship between young people and the same: everyone talking about, but no one has done. ”

Maintenance Pavilion DV9000 batteries notebook computer users has been a hot topic, but in fact there a lot of misunderstanding, in the final analysis from two aspects, one is “thinking does not keep up with the nickel-metal hydride batteries to lithium batteries of changes”, while a more comedy, from the phone, because in fact the majority of mobile phone users access to the first use of the equipment repeatedly rechargeable battery, it will take for granted some of the habits of mobile phone to the laptop was an extension of.

I did not intend to cultivate the majority of notebook users into experts, then there is no need, I just want to bring some of the most vulnerable to clarify the misunderstanding and give the correct perspective and practices.

A misunderstanding 1 : the need for notebook computers bought three times repeated charge-discharge in order to activate the battery.

Unless you buy a notebook computer is more than one year of product inventory, or need not do so because there are Pavilion DV1000 batteries in the battery when the factory has been activated, and the batteries in the package when the battery into the notebook, after a equivalent to the activation of the test, so you get the battery in hand, already have been activated, and again three charge-discharge process was an increase in unnecessary depletion of the battery.

Misunderstanding 2: the first charge must be sufficient enough for 12 hours.

This early stage those who do not have the battery control circuit of the Ni-MH battery models are applicable, but for now have a smart charging and discharging control circuit for the notebook battery is a joke, when the notebook computer battery is full, the charge current will be automatically cut off , even if you continue to charge 120 hours, there will not be any change in status, and generally speaking, even the slowest machine charge, 6 hours when fully charged, the rest of the “charge” is just a waste of their time. It is time to get new machines should be fully discharge first rechargeable.

Misunderstanding Three: the need for regular battery calibration, the total charge released once a month.

Strong memory effect for nickel-hydrogen batteries, which is an essential task, but for Li-ion Pavilion DV2000 battery, the cycle is too frequent, and lithium batteries does not completely eliminate the memory effect, but has greatly reduced the memory effect, if you use the battery is frequent, then you should discharge the battery to the relatively low (about 10 ~ 15%) re-charging, but even if the discharge to the open machines are not (0 ~ 1%), belong to the lithium batteries have greater depth of injury discharge generally every two months to do the operation once it. If you rarely use the battery, then every 3 months as long as the first such operation carried out on it.

Misunderstanding Four: correction to enhance the battery capacity can improve the battery capacity

The so-called correction, when the actual capacity of the Pavilion DV6000 battery and control circuit capacity not the same as the record, the depth of a battery charge and discharge operation, so that a record control circuit to the battery close to the actual situation, this is a true performance of the battery capacity rather than enhance the capacity of the operation, the key factor here is the actual capacity of the battery, if the actual battery capacity than the control circuit in the capacity to record high, correction can increase the battery capacity seems, if the actual capacity than the control circuit the capacity to record low, the correction will reduce the battery capacity seems also that many people debate the reasons for the effect of correction, keep in mind that correction is the true battery capacity is shown by the elimination of the battery and control circuit between the deviation, as demonstrated by the capacity will increase or decrease, this is the status of the battery itself, rather than corrected by your decision. Correction is likely because the battery discharge when the depth of injury, but a substantial reduction in capacity.

Many manufacturers provide a battery calibration procedure carried out, the Windows version and BIOS version, it is best to use these procedures to correct, Windows version can be carried out while working, BIOS version can not be like this.

Today, I made such a topic about that notebook computer users in the use, maintenance, and repairment could sum up some experiences to exchange for better management of their laptop batteries .

1. the regular production of laptop battery manufacturers a variety of parameters clearly marked.
2. buy laptop battery, the best choice nickel-metal hydride batteries or lithium-ion battery.
3. genuine batteries commonly used PC or PVC shell material is very strong, difficult to damage, the general means can not open the laptop battery.
4. neat appearance, there is no extra burr, a certain degree of roughness of the outer surface, and feel comfortable.
5. notebook battery into the battery slot should be around freely, and closely integrated with the machine, while attention to the battery nominal voltage and voltage to correspond to your notebook.
6. to ensure that purchase of the laptop battery charge and discharge of its good performance.
7. under normal circumstances the thinner laptop battery, capacity, the smaller the thicker the laptop battery capacity is also greater.
8. choose the laptop batteries and adapters necessary to ask the dealer asked in detail about the characteristics of batteries and adapters.

If you want to extend notebook battery life, we must also carry out proper maintenance of batteries and maintenance, the following is Ikunori maintenance and maintenance of notes:

1. to avoid laptop battery at a temperature higher than 60 ℃ or lower than -20 ℃ environment, otherwise the use of time and life will be shortened. Laptop battery charging basic method, because laptop battery characteristics vary, so it must be in accordance with manufacturers instructions manual method of charging.
2. if not a long time the machine is best to remove the laptop battery because the case does not boot, will be a gradual loss of laptop battery power
3. due to a general non-rechargeable batteries, lithium batteries, such as the forced charging will cause an explosion.
4. do not laptop batteries and some metal products together to prevent such metal objects touch the battery polarity, short circuit caused by the phenomenon.
5. laptop battery when not in use, if temporarily, you can temporarily release some of them power, but then save it.
6. due to its chemical properties of lithium-ion battery is extremely active in response to intense, so we should not arbitrarily to its demolition. If rain, moisture, dry cloth can be dry, put in dry and ventilated place on their own or with hot air drying of about 40 degrees.

Laptop battery safety forthcoming national standards

March 2, Ministry of Information Industry Digital Camera Battery released the 2006 top ten events standardization of electronic information industry. Independent innovation, national standardization of digital video, mobile phone standards for Chinese character input 10 was recommended as the standardization of the top ten events in 2006.

Han Jun, deputy director of Science and Technology Ministry of Information Industry said yesterday, last year China’s electronic information industry to establish their own national standards to obtain important results. National standards for digital video in which the introduction of two-dimensional bar code with independent intellectual property rights standards, mobile phone Chinese character input standards for 10 standard, is one of the player. According to Han Jun said, as at present, the Ministry of Information Industry has completed a “portable computer, mobile power system can be standardized,” the approval of laptop battery safety, reliability, environmental adaptability, quality inspection standards put forward the basic requirements and will shortly be officially released in the country enforced.

Chinese Electronics Standardization Association, pointed out DSLR Battery Grip that the responsible parties in recent years, frequent laptop battery fire and other major incidents, but the lack of standards and evaluation data related to the support of the rights of consumers can not be effectively guaranteed, including manufacturers and consumers has been to call for laptop battery safety national standards to protect the industry’s healthy development.

Japanese firms fought in solar cell production

While the world’s lithium batteries have been recalled frequently a problem when the major battery manufacturers have set his sights on solar cells in order to meet rapidly growing demand.

March 3, the Japanese electronics maker Kyocera will invest 40 billion to 50 billion yen, in the fiscal year 2010-2011 before the company’s solar cell production capacity to 500 megawatts. It is reported that Kyocera will increase the plant equipment at home and abroad, introduction of higher performance new products.

In fact, Kyocera has already started overseas expansion plans. Kyocera solar cell is located in Tianjin, China factory expansion was the second capital increase successfully completed late last year. Expansion is completed, the Tianjin factory Kyocera solar panels monthly capacity of Canon EOS 30D Battery Grip 3.5 megawatts or more.

In the meantime, the world’s largest solar cell maker Sharp will invest about 3 billion yen to improve solar cell production capacity from the existing 600 MW to 710 MW upgrade. While another solar cell maker Sanyo Electric Group, also plans to before the 2010-2011 fiscal year, at least invest 40 billion yen in the company’s solar cell business; Japan’s Mitsubishi Heavy Industries Group, the company also plans to increase solar cell production capacity nearly twice the .

The four Japanese companies accounted for 46.5% of the total output of solar cells. Order in connection with several other major rival to compete against the four companies have invested a huge solar cell business capital. With rising oil prices and the market demand for renewable energy an increasingly strong global sales of solar cells is growing rapidly, they can not pass up this opportunity.

China’s first fuel cell vehicle to start with Shanghai as the establishment of national standards “future car” fixed spectrum

Compared to the “drink” oil cars, the future “drink” of hydrogen cars, which in the end look like? It is the “heart”, “skeleton” What are the requirements? This is not who is able to have the final say. Recently, this reporter learned from the stock company SAIC, China’s national standards Canon EOS 40D Battery Grip for fuel cell vehicles in Shanghai, the preparation work has been started, including the “fuel cell vehicles vehicle terms” and “fuel cell vehicles vehicle safety requirements,” the two basic criteria to be completed in 2008. Standard first, is to give future automotive given spectrum.

Shanghai has been China’s hydrogen fuel cell car research and development base since 2001, “15″ major scientific and technological projects in the fuel cell car project is settled in Shanghai, have developed beyond the One, beyond on the 2nd, beyond on the 3rd series of fuel cell vehicles One of the most advanced beyond the first hydrogenation on the 3rd may be driving more than 230 kilometers, 100 km in urban driving only 1.1 kg of hydrogen, approximately equivalent to 4 liters of petrol, its maximum speed of up to 122 kilometers, 0 to 100 km / h acceleration time is 19 seconds, a number of indicators have been close to the current internal combustion engine car. More importantly, it provides a true zero-emission, the only emissions are pure water. Under the current plan, Shanghai will strive for the Beijing Olympic Games in 2008 to provide 100 hydrogen fuel cell vehicles, but by 2010, the World Expo 1000 will provide hydrogen fuel cell vehicles.

No rules, not a radius. With the hydrogen fuel cell vehicles to promote R & D and industrialization have gradually demonstrated the dawn of national standard-setting work, “surfaced.” SAIC manager of automotive standards and regulations YAO Chinese senior engineer in charge of introduction: fuel cell vehicles the preparation of national standards, enabling our country from the initial stage of fuel cell vehicles to achieve “standards first”, so that there are rules to follow, and a law, in order to the industrialization of fuel cell vehicles and in the future commercialization, popularization and application of large quantities provide an important safeguard. It is understood that fuel cell vehicles of national standards work from the early Canon EOS 300D Battery Grip stage of discussions began in March last year, at present, SAIC, Tongji University, the National Automotive Standardization Technical Committee, the China Automotive Technology and Research Center of the 10 enterprises and institutions, a number of senior scientific research personnel group became a special research project team, end of this year to form a “fuel cell vehicles vehicle terms” and “fuel cell vehicles vehicle safety requirements,” the draft, again seek the views of the entire industry to finalize these two technologies standard.

YAO Hong-hua, automobile terminology and vehicle safety requirements is the most basic and most important of the two criteria, the former able to provide various types of fuel cell vehicle industry name for a unified and names, especially for many traditional fuel vehicles do not have the equipment and technology, a unified definition, to prevent confusion; the latter is proposed vehicle safety requirements, involving the safety of fuel cell vehicles vehicle parts and components, system parts and vehicle safety requirements related to the operation of all technical parameters are defined and validated. The reporter learned from the establishment of two standard outline to see, all kinds of vehicle terms, nearly as many as 100, while the vehicle safety requirements are also divided into “general safety car”, “battery power”, “electric shock protection requirements”, etc. 11 aspects of the standards, in great detail for the “future car” fixed spectrum.

Geneva Motor Show: Auto energy-saving environmental protection into the theme of

March 4 report, as an international automotive industry benchmark of technological development, new energy-efficient cars and hybrid cars will be the theme of this Geneva Motor Show. Among them, wearing a – g show the low-emission diesel-powered cars and Toyota hybrid concept car Canon EOS 350D Battery Grip, represented by X.

The forthcoming opening of the 77th Geneva Motor Show will be even more concerned about global warming and environmental issues, including the new EU vehicle emission standards will be the focus of debate. Makers on how to make cars more fuel-efficient and environmentally-friendly display their new technologies.

Dai – g company will launch its environment-friendly green technology – BLUETEC emission control, and the four-cylinder machine to achieve the fuel optimization. In order to ensure to reach the Euro 6 emission standards for strict (six from Europe started in 2015), on the technical side, C220BLUETEC at the forefront. C220BLUETEC power 125kW, peak torque of 400Nm, 100 kilometers fuel consumption 5.5L, largely due to diesel engine technology and energy intelligent control system implementation.

Japan’s Toyota Motor Corporation will showcase the next-generation Prius hybrid Prius. Its batteries more powerful engine combustion more complete.

As the EU’s new vehicle emission standards require that by 2012, cars per kilometer of CO2 emissions can not exceed 130 grams to 163 grams at present, therefore, automobile manufacturers will spend more money put into the development of automotive energy-saving technologies.

Is worth noting that China’s auto makers will lead to smaller, more energy-efficient cars, such as Canon EOS 400D Battery Grip Brilliance Jinbei will bring its first sedan BS 6, this car will be aimed at European consumers, will be HSO Motors Europe, responsible for sales.

Other points:

Some of the best-selling SUV models in the market in the seat with the new changes on the layout, such as the GM Acadia, Toyota Highlander, these models will no longer be in the second row or third row of seats set up the channel edge pedestal, while the is designed as a whole, even though passengers up and down too convenient.

Worth a visit is in the “007 Casino Royale” in the image of concept car to debut, the entire new generation of Ford Mondeo chose to be officially unveiled at Geneva Motor Show. Which model offers three distinct body styles: four-door luxury sedan-type, 5-door sedan and station wagon model. In addition, the vehicle equipped with high-performance powertrain offers four DuratorqTDCi diesel and five Duratec petrol engine options, the output power range from 82.06km to 164.12km. This year in which vehicles will be formally launched in Europe.

In addition, BMW will showcase its new 5-Series, will showcase the new Volkswagen Golf Estate.

It is reported that more than 250 companies will participate in the laptop battery Geneva Motor Show exhibition area of 77,000 square meters, estimated attendance will be 70 million, show time is 8-18 days in March.
