Q: the battery a long-term need, it should be how to preserve?
A: Charge or discharge to about 40%, and then placed in temperature of 15 to 25 degrees Celsius dry preservation, the temperature is too high and too low are easy to accelerate cell aging.

Q: The battery does not remove the books to each power supply will you?
A: It does not matter, the laptop battery protection circuit again, full of will not continue to charge the

Q: My battery is now only a very short period of time, how should I do?
A: If you’ve been in the frequent use of the battery, then it belongs to cell aging, which can not be avoided, you can only consider the change a new battery or if the replacement batteries batteries; If you do not have battery long-term, may also lead to this phenomenon, this time need to completely discharge (up to fail to boot up) and then full power, repeated several times to activate the battery.

Q: laptop universal power adapter can do?
A: No, there are three obstacles, the first is the notebook computer manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, are inconsistent. The second is different from the needs of current laptop is different from the 2A ~ 5.4A have a small machine needs a smaller current, big machine in the latter case. The third is the various manufacturers notebook power adapter interfaces are different, it is difficult general. Therefore, at present do not yet common to all the notebook power adapter

Q: How should the new machine bought charging it? How do I maintain the battery?
A: Lithium (ion) battery is the need to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, to achieve full charge when the full release, in general, the first three can be a period of about six hours of charge time will be tight, like electric charge to 100%. To avoid the use of point charge, less than 10% of the time to charge a timely manner and not to be exhausted, so that the battery but there is injury; also higher than 60%, also try not to charge. A long time without battery applied to about 50% of electricity at room temperature and dry environment preservation.

Q: Why does my IBM laptop is always in use when the battery power than with the low brightness when a file?
A: This is the IBM default settings for random power management is aimed at energy-saving:), if you do not like it, you can control software in IBM’s ThinkPad Configuration Utility, select LCD project, then changed to High brightness from Normal can be. The Display option in the BIOS which have the same settings. In fact, the purpose of doing so is to power.

Q: for the first time the use of the battery, the former three to be recharged in 12 minutes?
A: This is not necessary because the current laptop has a sound management of electrical power
Road and charge management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state,
Thus, even in sufficient time for however long to no effect.

Q: In order to prevent memory effect, we should run out before electric charge do?
A: Every time charge of battery discharge is not necessary, but also harmful. Practice has proved that the battery deep
Degree of discharge will shorten the life of unnecessary, it is recommended to use when the battery is only about 10% when you can charge
Power of the. When the battery power is still more than 30% of the time advisable not to charge, because the memory effect is indeed
Exist more or less real.

Japan Ferrotec from China Comtec Solar Systems Group (Comtec Solar Systems Group) has received 150 solar cells with silicon ingot furnace orders. Will be delivered during 2010 to 2011.

Comtec Solar Energy Systems Group is engaged in solar cell using single crystal silicon ingot and wafer design and manufacturing business. The company is Ferrotec’s major clients, Ferrotec had produced about 600 single crystal silicon ingot furnaces have 120 available to the company. Comtec additional orders may be due to the impact of the financial crisis, the stalled solar cell market, “there signs of recovery” (Ferrotec).

Ferrotec said the solar cell market started to recover reason is that market demand in Europe to restore the same time, new markets such as China’s growing demand. The company said solar cell makers completed the inventory adjustment, production and capacity utilization has been restored, so the business from the Chinese manufacturers continue to increase.

Microsoft plans to release next Monday for faster Internet access copies “Pine Trail” Atom processor, in order to access this market to add some performance.

The major PC makers are expected to be announced the adoption of this new processor, new products. According to a person familiar with this news, Intel will launch the N470 Atom processor and the current 1.66GHz processor, the N450 is almost, but the speed increased to 1.83GHz.

Improve the speed of each point is helpful, but when compared with other mainstream processor chips, Atom processor’s performance has been limited. With the mainstream Core 2 and Core i mobile processors, the Intel Atom processor, used for a different architecture, providing a higher energy efficiency, but low performance. Atom processors are generally used for the price at 350 dollars or less access to this, almost all single-core processor, while the faster dual-core processor for mainstream notebook PCs.

Intel launched late last year, the latest “Pine Trail” Atom processor, integrated graphics chip functionality. Before this function is a separate chip.

According to the relevant news that Intel may plan will be launched before the middle of this year for the high-end smart phones and mobile Internet devices in the new “Moorestown” Atom processor. However, as the “New York Times”, as first reported, Intel and TSMC has been temporarily suspended between the relations of production based on the Atom processor.

It is familiar with the relationship between the two chip-making giant, who said the joint production of TSMC and Intel processors for handheld devices has not been a lot of user requirements. For these two companies, to find the right product, engineering and intellectual property portfolio has always been a challenge.

Many consumers use a digital camera, we often encounter such a dilemma: to buy when the battery is clearly nominal × × mA × × to shoot photos, but in actual shooting, much less than the nominal performance when the power is quickly exhausted. Many consumers are easy prey for manufacturers such an explanation: “Nominal performance is carried out under laboratory conditions in a particular operation, the actual use will be lower, the battery does not have problems.” In fact, in most cases, the problem is precisely the root of the battery itself.

Since 2002, in the fierce market competition, among the various brands of digital cameras has reached the price of Bosha near tragic proportions. In this case, the dealer profits is expected to lock in the Inspiron 700m battery, memory card, camera bag and other accessories on the inevitable. “If there really presented an original battery, it is surely to lose big. A common brand of genuine original battery, dealer delivery price of 150 yuan in general have to -200 yuan, market prices generally are in yuan or 240 yuan -300 higher. This is not possible to send in original equipment batteries, but the dealers will be presented with the consumers that a battery, if consumers have to be original equipment batteries, dealers will tell you, is to send original battery. “batteries for the gift inside, a brand, people are not shy, “Our dealers are often so dry, we are also open eyes eyes closed eyes.”
People know are familiar with the battery to measure strengths and weaknesses of the two important indicators of the battery, one battery is full, and second, whether the discharge remained stable. The survey found that many gifts the actual charge capacity of the battery shortage, easy to leakage, contamination camera Inspiron 710m battery pack, and loss of life of the camera. Moreover, these cells discharge less stable, in the process of using unstable, prone to discharge the battery too quickly lead to heat hot camera or even crashes, serious short-circuit may also lead to the phenomenon of the camera. Consumers not an expert, can not possess the ability to identify the strengths and weaknesses of the authenticity of the battery. The best way is to give gifts battery, because the gift purchase price of the battery definitely better than the actual market dealer claimed to be much lower. If you have to choose gift batteries, it advised consumers to take the time to investigate more.
If the gift is a dedicated lithium battery cells, focusing on original battery to find out the obvious signs, if no time, no ability to investigate, necessarily require dealers in the receipts, invoices, warranty cards or product configuration list, clearly marked: “presented a Yuanzhuanglidian pool, identify the code is so many. “Once a gift is not the original battery, you can claim accordingly.
If the gift is the universal battery cells, batteries would need to see clearly whether the gifts mainstream brands, if not, the best ask for replacement. If the dealer insists on not changing, it is recommended to consumers the value of deductions claimed by dealers to buy camera, while his reputation from the market purchase a good mainstream brand batteries(compaq Evo N620C battery， compaq Presario 2100 battery), must not yield to the temptation to adopt the moment cheapest gifts of counterfeit or poor-quality batteries to avoid damage to the camera.

Nvidia said that the market next year will be more than 50 notebook models using Optimus technology.

According to foreign media reported that Asustek plans to sell a variety of Optimus access to this, including UL50Vf, N61Jv, N71Jv, N82Jv and U30Jc. Optimus technology allows equipped with an integrated Nvidia graphics processor and discrete graphics processors, the notebook can automatically switch between the two, the system can take full use of resources, improve system performance or extended battery life.

Insiders pointed out that relative to the current dual-GPU configurations in terms of, Optimus technology is an improvement. At present, the user needs to manually integrate stand-alone graphics processor and graphics processor to switch between.

Nvidia claims that, Optimus notebook battery life can be extended up to 2 hours, “like a hybrid vehicle in motion in the gasoline engine and electric engine to switch between different, Optimus choose more suitable for notebook graphics processors.”

Optimus Technical Support Windows 7, Intel Core i3, i5, and i7, Ling Dynamic N450 and N470, Core 2 Duo dual-core processor, Nvidia’s GeForce 200M and 300M Series graphics processors, as well as the Ion 2 chipset.

One can improve the efficiency of solar photovoltaic power plant using the “flow battery energy storage system integration and application of solar power generation demonstration” project, through the establishment of pilot demonstration in Lhasa point of testing, has recently completed the technical design and feasibility studies as well as the load line connection, etc., the project is expected to plateau this year in the city of solar PV power plant application.

Energy Demonstration Center, Office of the Tibet Autonomous Region, Li Jinxiang, director of presentations, solar photovoltaic power station in Tibet was build by using the battery, its lifetime is only three years, while the use of flow energy storage battery systems could take more than 15 years. Application in solar power, not only can reduce the use of cost, but also build the battery to reduce frequent replacement caused by environmental pollution. At the same time, but also solve the solar power, wind power exists in the electricity supply has fluctuated, the voltage instability problems.

This reporter learned that flow battery energy storage system is composed of a battery and a cathode storage tank, an anode composition storage tank. The principle is through positive and negative electrolyte solution in the activity of valence changes of vanadium ions to achieve electrical energy storage and release. The image that is deposited in the excess of electric jar, to use when the transmission went out again in order to ensure the stability and continuity of supply when.

At present, various types of solar photovoltaic power generation facilities in Tibet a total capacity of more than 9MW, Tibet is China’s highest rate of solar energy application, the application surface and the largest and most versatile of the provinces and autonomous regions, solar resources are widely used in agricultural and pastoral areas lighting, radio and television , boil water for cooking and heating in areas such as well received by the masses of farmers and herdsmen.

To informed sources, in order to Tablet PC iPad, Apple CEO Steve Jobs (Steve Jobs) recently hosted a banquet for 50, “New York Times” executives.

This week, Jobs meeting in New York, “New York Times” and “Wall Street Journal” and a number of media companies, hoping to provide content for Apple Tablet PC.

Informed sources said Jobs in New York, booked a hotel dining room Pranna to as the “New York Times” executives negotiating room. It is reported that Steve Jobs hosted a banquet for a total of 50 “New York Times” executives.

Last month, Apple released the industry’s long-awaited Tablet PC iPad. It is equipped with 9.7 inches screen, using A4 Apple 1GHz processor, storage space up to 64GB. Next month, iPad will be officially listed.

IDC cited industry statistics, said the Acer 2009 a total of 4 quarter of the global market, shipped 9.5 million notebook computer, its rival Hewlett-Packard’s notebook shipments over the same period of 11.38 million units, the gap between the two from the previous quarter, when at least 105 million widening of .2009 to 1.88 million units in the third quarter, Acer shipped 8.86 million notebooks the same period, HP shipped 9.91 million units.

The source said that Hewlett-Packard a series of promotions during the Christmas activities are widening and Acer shipments in the gap between the main reason for Hewlett-Packard will be the price of its flagship model reduced to 300 dollars to attract consumers. At the same time, due to the notebook market saturation, as well as ultra-thin models on the market demand for smaller, Acer 2009 4-quarter sales growth of just 7%.

Hewlett-Packard plans to ship 4,400 million in 2010 notebook computers. Acer reportedly ready to launch in the market mainstream configured thin notebook computers, striving to break through 40 million units by 2010, the original plan shipments.

A specialized repair Apple products, the company said, MacBook entirely on the camera can be installed on iPad tablet computer.

Available from the iPad has passed nearly a week time, but the public will have the new version which features has been warming speculation.

Recent topics focused on whether Apple’s built-in camera for the iPad. In the January 27 in San Francisco organized by iPad conference, Apple CEO Steve Jobs (Steve Jobs) made no mention of this.

Nevertheless, the current built-in camera on the iPad would be the most reliable evidence comes from a Kansas Horacio in the United States a company specializing in Apple products, the company said in its blog, the first batch of parts and components, there is a reserve iPad a camera interface.

The company also found that Apple’s MacBook, removed from the camera can come installed on the Pad’s interface. The company Monday said: “wiring the mouth of the lens LED lights also can be a normal start, the location of light-sensitive device is also no problem, this shows that the iPad will be built-in camera,” “estimate, the camera will appear in the next version of the iPad on, Apple has so far not released any new features iPad plan, so fans can only be a temporary wait for this. ”

Despite the iPad not yet available, etc., have attracted a lot of comment on the sound, for example, there is no camera, can not run multiple tasks at the same time, does not support Adobe Flash and the lack of high-definition video interfaces.
