Currently, the battery testing and monitoring has gradually become a hot topic, power systems, telecommunication systems, systems of mobile communications industries and other information are all tests of the Laptop battery and monitoring progress relevant requirements, the major manufacturers to actively develop the products concerned.

 

Information security and security of electricity supply point of view, battery monitoring and battery itself has the same importance. In the highly modernized society today, it is difficult to imagine the power grid electricity, telecommunication network to the social, political paralysis and economic losses. To avoid such losses in the corresponding devices use batteries as a source of backup power, so that even if a power failure, but could easily adopt other emergency measures to prevent occurrence of losses. As with other electronic components, batteries, as there is problem of early failure, but the battery there are still problems correctly, the IBM 40Y6799 battery monitor in these two aspects is to improve system reliability, which means hand One, the monitor can cause the battery in the right running the state, secondly to monitor the failure of the battery can be found soon. Thus, the battery to control the safe operation of critical systems has an important meaning.

 

Battery monitoring is not new, its history almost as long as the history of lead acid batteries, but because of electronic technology and information technology to give only one injection of new concepts. From a user perspective, only the battery voltage and battery current monitoring of these products have been unable to meet its needs, with single monitor cell voltage has an internal resistance of a battery and follow the product is increasingly used. On the other hand, new technology has been widely adopted, the relay contacts to switch gradually disappear replaced by electronic switching batteries advanced technology single-chip to monitor the product has a powerful feature, signal processing to enable digital tracking of products with higher accuracy and reduce costs. A variety of applications in this area so that a new generation of Dell Latitude D810 battery monitoring have improved continuously from all angles.

 

Battery users are more concerned about the battery monitoring products can meet the security requirements of their application. The battery on the market products is not able to monitor user satisfaction. From the results of national research and foreign, outside voltage single cell monitoring to detect a short-circuit the battery and the battery of this type of battery failure, the decrease in hard to find pairs of battery capacity, reduced battery capacity was the main failure mode of the battery, only the resistance of the battery’s internal monitoring may indeed find these batteries.

 

Product performance and cost is that the user is most concerned about two issues. Operating parameters on hp Pavilion ZE2000 battery monitoring products on the battery pack a big help for the smooth functioning of the battery has not been detected failure of basic capabilities with a single product stack voltage monitoring can be found as the cell types of short circuit and open circuit the battery cells such as for serious offenses on the battery capacity decrease little or no detection capability, an internal resistance of the battery monitoring products to meet requirements for high security application requires. Operating parameters on battery monitoring products with the lowest cost, most single cell voltage monitoring products have a lower cost, has an internal battery resistance monitoring, higher commodity costs. There are also specific needs of users of large volumes of high-performance products available for selection. As the security of application systems, the system can not still under maintenance, on-line monitoring to better meet this demand. On-line monitoring can also improve efficiency, more accurate and reliable completion of the tasks of monitoring battery. Battery monitoring networks and have a close relationship. In addition to software, network security, system management and other issues, but also a close relationship with the material, while monitoring the battery is a key factor should be one of the issues. On the other hand, in view of automation of surveillance, monitoring network is electricity, the characteristics of the communications industry, which requires monitoring of battery products with network compatibility.

Ohio State University researchers said when the production environment of the Earth, solar-friendly, the rose could be a new “green.” Scientists have developed a new dye sensitized solar batteries (DSSC). The Laptop battery used by the color red and white, mixed metal oxide powder pink showing, you can catch the sun.

 

Apparently, these new pink materials, is the best material for photoelectric conversion, despite the conversion efficiency has been implemented in commercial silicon solar batteries by half, but its cost is only one fourth of solar batteries silicon.

 

Pink dye sensitized solar batteries is the most typical color. Most dyes contain a ruthenium, ruthenium red. With the red dye mixed with rose powder most commonly used metal oxide is titanium oxide or zinc oxide, these two types of metal oxides are white. However, researchers at Ohio University created a IBM ThinkPad R50 battery more innovative materials does color, they used metal complex, exploring different particle shapes to improve performance of photoelectric conversion.

 

This is the first time, researchers use non-unique dye manufacturing oxide sensitized solar batteries. Choose stannate zinc because zinc stannate belongs to the complex oxides with tunable properties. This characteristic makes the next cut of dye sensitized solar batteries possible.

 

Why dye sensitized solar batteries are pink rather than blue like silicon solar batteries do? Traditional solar batteries with a Dell Latitude D510 battery blue because the fight against the causes of reflective coating. These include improving the absorption of light green, light green spectrum is the most powerful solar light. Ohio University researchers developing complex materials and it is not anti-reflective coating.

 

Color determines the solar battery can capture the wavelength of light, scientists can change the color of the special characteristics of solar batteries optimized. Currently, the development of dye sensitized solar batteries, scientists have used ruthenium red dye obtained the best results.

 

If you want to get the best efficiency, we must consider access to voltage and current. The tension is a kind of material can provide the potential energy, now is the amount of material capable of transmitting the hp Pavilion dv2000 battery charge. If you can absorb a wide range of wavelengths, it would have to sacrifice power. If the absorption of energy limit is very high, can achieve high voltage, but had to sacrifice being. Researchers want to find a fair balance.

 

Since the 20th century, 60 years since the silicon solar batteries appeared. Since the 20th century, scientists began to develop the dye sensitized solar batteries 90. In the dye sensitized solar batteries, dye molecules cover the tiny particles of metal oxide have lived, and with the insertion of a thin film. Dye molecules capture light energy and release electrons, while the metal oxide particles was more like a thread, will be among the electronic transmission to the circuit, but the transfer of electrons between the particles may be lost. These researchers are developing tiny sony VGP-BPS5 battery nanowires to merge to be sent directly to the causes of electronic circuits.

 

They are also exploring the possibility of using nano-trees – nano-son-shaped tree branches etc.. Which structure is to absorb light and improve the current structure? The researchers studied tree! Leaves provide a large surface for capturing light, the branches will be transferred to the roots of nutrition. In their design of dye sensitized solar batteries, dye particles will cover the surface, the nano-trees do not grow between the leaves of these branches, electronic transmission.

 

Therefore, the following dye sensitized solar batteries grow a tiny tree “pink”, but other colors are also possible. Researchers are studying to work better in the new apple A1008 battery dyes and dye compounds.

HP again exposed blue screen, after-sales service is widely questioned

Posted by admin on October 21, 2009
HP laptop / No Comments

The annual sales income over 100 billion U.S. dollars, operates in all key areas of the computer industry, Hewlett-Packard, took first place in the PC market after the quality of their products they are often caught in the crisis of confidence in the brand, following the charts, screens, batteries, etc. took place after a dispute over the quality, the most recent case is that HP E9105t models desktops and improved hp 367759-001 battery version of the computer problem E9108t blue screen, which is currently abroad caused dissatisfaction of many users.

 

“Economic Daily News” reporter has learned that hundreds of overseas customers have been planned collective complaints and its improved version of the HP E9105t E9108t computer problems blue screen, which Hewlett-Packard of China public relations person in charge of enterprise PSG accept the “Daily Economic News” reporter, said that since the two desktop products are not available in China, so the issue has no impact on users china. However, according to “Economic Daily News” reporter has learned, in fact, even before this incident, HP “Blue Machine” was published in the Chinese hp Pavilion ZE2000 battery market.

 

It is remarkable that in recent years has been consumer complaints about product quality and in case of HP, and more incidents of overheating of the battery were treated reminder of HP, other users of computers in question were not the ideal treatment, which also allow the quality of HP after sales service widely disputed.

 

There are also Hewlett-Packard machines to blue screen”

 

According to Zhongguancun in Beijing, and outside on the streets of the computer channel will present the city from April 2007 onwards, due to “sudden Hewlett-Packard cut prices of all models, “then HP laptop sales in Beijing and the computer market in the country showed an eruption.” Zhongguancun channel Wang Jun (a pseudonym) Analysis: “HP is a great hp Pavilion dv4 battery brand, previously, price is always higher than other brands when the price low, people buy more naturally.”

 

However, the top of its price cuts come with HP sales eruption “lasted only a few months.

 

According to Wang Jun, the second half of 2008 to begin buying prices fell Series V3000, DV2000 Series, compaq6000 series models such as the use of laptop users there, where a variety of models V3000 series a “blue screen of frequent and automatic restart” issue.

 

June 2007 Hewlett-Packard model V3159 bought in Zhongguancun, laptops, said Mr. Ho, his notebook in early 2008 began to emerge from the blue screen phenomenon, from November 2008, began to frequent blue screens all the day there will be two three. He suspects the software blue screen may be caused by the conflict, if Ho reinstalls the system several times, but he told reporters he was trying to install a variety of operating systems, the two hp 338794-001 battery can not solve the problem blue screen.

 

Press investigation revealed that this phenomenon occurs not only in Beijing, Guangxi, laptop users HP V3000 presented by Mr. India, and V3000 is the beginning of last year in Nanning to buy Electronic Science and Technology Square, since the use of ordinary blue and death, he worked this get your own laptop service centers HP Care Pack requires an interview, but the other party asked for blue screen when the new portable-Na Qu interview, Mr. India and it is difficult for him to accept HP product of the attitude of consumers of services hp PB992A battery.

 

Wang told the “Daily Economic News” journalists, HP handheld products, sales decreased significantly in the second half of last year, “the time there was a big snow-screen events so much noise, much of ‘buyers were interested in the Hewlett-Packard in consultation with the change after the other brands, but in 2007 sold the shipment of high rates of repair, so we reduced the volume of HP in general take is someone takes on the basic non-prepared stock. ”

 

Bad motherboard problem? HP does not take

 

Mr. Ho and India revealed that in the face of the HP laptop blue screen problems, they have posted online with people to discuss and find solutions. “Most experts agree that this is not a software problem caused a blue screen, the problem probably lies in the motherboard of the machine.” They said.

 

Coincidentally, a few days ago by the blue screen problems abroad, Hewlett-Packard desktop users out of this under the same conclusion.

 

July 19 of this year, claiming to be Cee Cee-users in HP technical support forum post to talk about his new hp F4809A battery July 10 Hewlett-Packard bought e9150t office nine days time, “the strike met 10 times . Cee-Cee question in this post 3 months after October 19, citing the response has already had up to 193, there are hundreds of users described in this quote their own use within the office e9150t HP and blue screen appears e9180t, automatic restart, and questions of the accident, there are 122 users have scheduled a joint complaint on the issue, has asked HP for a replacement computer.

 

In the posts, many users have reported having tried a variety of methods to identify the root causes of blue screen, and use different settings and drivers, switch to a different operating system, but the screen problem Blue is still pending. In their view, the most likely outcome of a blue screen problem is the motherboard. According to the poster says, e9150t and e9180t use the model of motherboard pegatronIPMTB-K.

 

While mobile users in China and office users abroad, the blue face of problems are always the product of the Board of Directors of HP has raised questions about quality, some users think of other HP products may be due to the same type of motherboard and the emerging problem of blue screen, but the press before, Hewlett-Packard had not yet been placed on the “Daily Economic News” highlighted “China in the HP products hp PB995A battery listed, use the same models that are used by pegatronIPMTB e9150t and e9180t model – K, motherboards,” “The products in question to a blue screen, HP will remember,” responded positively to these questions. HP said only that the two previous office products are not available in China, so the issue has no impact on users in China.

 

Quality of service has been criticized

 

It is noteworthy that Hewlett-Packard, not only did not respond positively to the blue door, but also for older graphics cards, door, screen door flashing, the screen door snowflake models involved are so far failed to take the recall, or other hp 346970-001 battery measures. The HP Service Department Gold service quality service center, since the snow on the screen since the incident came to light is also widely criticized.
