HP Laptop Battery Super Blog Here

MP3 player makers early in order to reduce costs, once the use of 7 batteries as a power system, and players get smaller and smaller, 7 cells had been eliminated, and lithium batteries become a standard. The advantages of lithium batteries is obvious, but life is limited, once the increased use of MP3 players, 40Y6797 batteries, using real time is short in late May that persist in less of 30 minutes, MP3 player, Hey do is the result of fragmentation?

The battery is broken, how do

If the warranty period, this problem occurs, we suggest that you’d better go after-sales service, in most cases you can receive a free replacement service if the private sector inside replace the battery, then the only years warranty has expired, is not worth the candle.

If past the repair date, you can search through the network the first look at MP3 players in your hands models lithium VGP-BPS2C battery used in what is, in particular the tension to be constant. Hot Models in general the mainstream, such as Meizu, Apple, Samsung, trademarks Onda, online can not directly buy an alternative to lithium battery standard, as the instructions to respond to the gift of the battery of specialized tools, the machine can be themselves outside Quhuan hands.

However, a significant portion of the MP3 player, use lithium batteries are non-target, then how should we do? In fact, we can go to the local mall to buy electronics for lithium batteries same voltage (at best the same size), different lithium battery voltage should not charge the MP3 player directly above. Such as the battery voltage is 1.5V home and the purchase of the battery voltage is 3.7 V, then they must be connected to the middle of a step-down IC, so s to ensure that the circuit will not be burned.

Note that to prolong the maintenance of lithium

We need to stress, MP3 player, use in their daily care and maintenance. If you buy a new MP3 player, then three times before the charge commonly called an adjustment period, more than 12 hours should be sufficient to ensure full activation of the lithium-ion activity. Although there is no memory effect of VGP-BPS10 battery, but there is also a strong inert, should have the full activation can not be guaranteed to be used to achieve the best performance.

When the environmental temperature reaches above 35 ℃, rechargeable Lithium-Powered will not take as long as usual, when the ambient temperature to 4 ℃ below, also appears to reduce the use of time, situation now is better not to charge the battery. To play the greatest performance of lithium batteries often need to use it, so that the lithium-mail is always in motion, if you do not often lithium electricity, must be placed shade to reduce the speed of passive reaction and a charge in advance, to prevent the battery due to excessive self-discharge, which led to excessive discharge, reduced life expectancy in the Conditions permitting, the best lithium batteries once a month to “reject small shallow filling.”

“The phone is run out of battery! There were no solutions here!” In the delayed take-off flight, a passenger holding a head of cell phone power scratching frustration. This reporter has learned that in many cases, the aircraft to the terminal were not even meeting to provide support to the power, so that part of the rush to a VGP-BPS2C mobile phone or laptop to charge passengers “watches the power of the Qing Tan.” It telecommunications experts believe that mobile phones and other electronic products and supplies more widely used in aircraft and the airport, airlines pricing power to become one of the keys to improving the quality of service.

Survey conducted by journalist

Most domestic flights without charging services

Wednesday due to heavy fog in Beijing, Guangzhou and other cities of all flight delays leaving for Beijing. One of the two planes on standby hours, a number of food shortages for mobile phones, but the emergency treatment of passengers on official business, such as ant’s wok. “Are arrested at the airport, almost two hours, I hasten to make international calls to deal with some official! By phone can not solve the problem because many 40Y6797 materials and contact lists are in the Ah phone! ” One passenger said the plane without requiring equipment may also not be off the plane, only interested in filming.

Passengers reported that flight attendants can charge their cell phones, but flight attendants have regretted that, due to the voltage and frequency are not the same as the power of the aircraft can not be charged the passenger’s mobile phone. According to the flight attendants put in place, in addition to individual flights, the airline is currently the vast majority of their flights were unable to recharge their cell phones, “because these are all requirements of the United States and europe, its orbit is not the same voltage and frequency modulation, forced to load flights that will damage or cell phone.

Currently, most domestic flights, even flights of very senior business class airline, but will only provide power to charge in an emergency only. In the high-altitude aircraft to provide services may charge a little bit extravagant, but said that passengers in the airport terminal, in addition to the VIP room, charging is also very difficult. Wong, air passengers, senior told reporters he had on several occasions in the Beijing airport, a cell phone charger for charging failure, “I do not know, it’s a bad charger n has not repaired or for other reasons. ” And because the airport terminal and the shortage of electricity, the VGP-BPS2B power plug is also very little, very often, although coverage of the wireless network must be perfect, passengers will not be capable of using laptops.

Fortunately, some of the premium airlines domestic and international have been aware of this problem. The journalist interviewed a passenger aircraft German said that European airlines first and business class at the bottom have the power. “Providing passengers to provide feedstock is technically no problem.” Although experienced observers Telecom Xiang Gang Li also told reporters that the Air China flight to fly to the United States, mainly for passenger with food, Hong Kong Dragon Airlines international flights are also similar services.

Expert Advice

Airlines can provide payment services

3G era arrived, cell phones more than just voice communication, but also under video, listen to music, transforming the Documents tool. Not to mention the air has become an important place in the ‘laptop. Therefore, in charge of aircraft and airport access services are increasingly important. “One industry analyst of the case to the press. In the VGP-BPS9A/B long flight, using a variety of electronic products to take advantage of multimedia to relieve boredom, or continue to use the high end phones and business laptops to handle the paper work of many fly Keystone habits. The habits and planes at the airport and even the contradiction between the disadvantages appear to load up.

Ultimately the way to solve the problem? Insider’s commentators believe that the contradiction between supply and demand in all areas to solve the same way as paid services is a very realistic approach. Commentators believe that airlines and airports label price may provide pricing policy, so it is necessary to measure the freedom of user choice.

In addition, observers also believe that because of the increasing number of domestic flights, blocking the air breathed air traffic control has become increasingly serious, and to avoid the dilemma described in Article beginning of frequent occurrence, each aircraft must be equipped with at least one to two power outlet. Of course, the dilemma does not charge VGP-BPS10 exist in the aircraft. With the Wuhan-Guangzhou line at the beginning of comparable aircraft, high-speed trains will become increasingly popular in China. So, they are packed with white-collar business high-speed train, it should also provide enough power to allow mobile phones to communicate, so this laptop continue to work, it is useful to people seriously relevant factor .

Singapore Airport Why blocks any power?

Mobile phones, laptops, MP3, MP4, PSP games, e-book … to transport a large number of electronic devices, “night” will no doubt take the load to the airport, a high demand for services. But it is interesting to note that, according to telecommunications experts, Xiang Li Gang introduction, despite the BTP-43D1 Singapore airport design may be the most luxurious in the world, the airport service is one of the most perfect but this is the most advanced airports in the airport of feedstock are “locked” up does not allow the use of. Why is this case? It turned out that Singapore is very small, inexpensive and high-speed trains and airports have improved the coverage of broadband, many people actually turn dedicated high speed train to the airport go to the free Internet access. In consequence of this approach, “rub net is a lot of people, the Singapore airport, but take one careless move and will be open free to use food are all sealed

Used in fast voltage control load to avoid overloading the internal methods of detection, most common are fixed, temperature control and more control, or mixed-use three ways.

1. Constant voltage control

When the battery voltage is detected at a voltage almost bit set to stop the charge. This approach is the easiest way to know that as the characteristics of the Laptop battery in the battery voltage curve upward, you can detect the voltage to the nearest filling when the quasi-saturation space, different styles of recharge battery when the voltage is almost saturated like the old and new batteries are not the same characteristics, using this method can not put more ideal tension. Although this method is simple but also very dangerous, said earlier, temperature is higher than the battery voltage and reduce current load will be raising the temperature of the battery, so it may have been perceived the battery voltage has not yet reached saturation, but the quasi-set position, and the battery charging voltage does not increase after saturation began lower and thus the consequences of overloading is very serious, if it comes with an internal short-circuit the battery charger is not able to protect the circuit, once the current consequences are too dangerous would be unthinkable, so this way during charging, the user should take note.

2. The temperature rise control

Battery charge generated during the oxygen saturation in the cathode of cadmium oxide and heat of reaction, the battery temperature begins to increase rapidly using this phenomenon to detect when the temperature reaches a certain extent, both the end of the load. In the same amount of charge under the current load plus the increase of the higher temperature, so if the load current is too large to meet the set temperature of the 40Y6797 battery may not have been saturated, but the current if it is too small, then oxidation to absorb quickly the temperature does not increase significantly, the charge movement was to continue but can not terminate. In addition, this approach will be affected by ambient temperature and can determine the battery temperature is in the self-product of chemical heat, or the environment caused by the heat of denial of justice, so this method in a high temperature environment will be charged absence of a cold is too cold.

3. Control

Charging the battery voltage increases as capacity increases load when the load capacity to reach saturation, the voltage rises to the point, and instead began to decline slowly. Enjoy this voltage drop characteristics can be used to control the voltage charge termination shall be when the drop was not more demanding, typically 1.2V nickel-cadmium batteries will be 20mV of its decline is almost complete (the actual size of data May refer to the VGP-BPS8 battery) in the process of charging can be clearly observed count Out. curve of charging voltage of battery is charging current and temperature effects in the same load capacity, the current is higher or lower temperature, the voltage increases the margin is low, the decline is also more obvious. Current is smaller, or the higher the temperature, the voltage increased the smallest rate of decline is relatively flat is not easy to distinguish. Therefore, control methods applied fairly rapid charging years, and to avoid the influence of temperature to detect the failure, usually with the control of the temperature increase in the use, in order to avoid overcharging.

Nickel-cadmium batteries, they are saved by the use of long-lost, or have already dusk, and the first few minutes before recharging will take place and the tension is not only the filling of the case will also down then up the cases involving the termination of a miscarriage of justice charges. Control method is a better method of controlling the characteristics of different batteries can still use the features of the batteries fully charged issues, the comparison does not need to worry about voltage control or adjustment the temperature function and damage the battery.

Currently, computer advanced many controlled chargers are the use of such control, and the price is expensive than ordinary chargers, and some of the reputation of the name even if, in fact its control programs and the load circuit is not their design, have tended to have misjudged the situation, rather than the battery charge enough to cook an egg, which is not even enough to strike are not yet sufficient to determine the battery was full, so better a charger in addition to increasing the temperature beyond the control of, and then under the non-recurring charge, voltage and current size evolution, calculate the load capacity and to determine if the VGP-BPS9 battery has really reached the saturation point.

The three methods are fast charging method, after loading, depending on the characteristics of the battery self-discharge, usually on the battery to continue to impose a small surcharge to offset the current battery leakage underway, and the speedy and can not be be able to achieve one hundred percent guarantee that is fully charged, charging a small current to continue to fill gaps in just to fill the building. usually about the size of the C / 20 ~ C/40 additional current between the general use of the fast charge mode the charger to recharge the battery to terminate after all Kangjing OK to enter what is called the slow charge mode Indeed, that is, as a small current to continue to supplement battery charging. In this mode, the small current is almost not let the battery produces little heat, not letting the tension is much change for shippers are almost always intended to complement the purposes of collecting and will not stop not automatically, but not yet as to the apple A1022 battery battery caused by overloading, but to avoid increasing the crystallization behavior of nickel, users always have the discretion to add time of pricing.

Moderator: Thank you, Mr. Tang Yao for his excellent report. Occasionally, we also do not ask questions, and Mr. Tang Yao just to the turbocharger has given us in-depth coverage of how to improve the performance of turbochargers and their future multi-Honeywell series-parallel under high pressure, including manufacturing and process technology. Here we enter the second period of the main speakers, the theme of light motor technology, automotive automotive light is now set up Auto Alliance launched light. Light Technology, the theme of cars, notably through two aspects: firstly the existing traditional techniques in the chassis, engine technology development, how can we make new efforts? On the other hand, we may be inseparable from 40Y6797 technology and manufacturing process technology, including technology development. Or to a greater extent, to implement advanced technologies must be adopted by advanced materials and processing techniques arise. So today, we invited three people in the back, behind the materials for automotive technologies to develop more in the sense of giving us a lesson. Finally, a report on the processing technology.

Here, we invited Evonik Degussa Co., Ltd. Automotive Group Manager, Hyde-chi, the report is a new small car design – two of the notion of material suppliers.

Hyde-chi: Good afternoon, ladies and gentlemen, is very grateful to the President just made my presentation. I am a German engineer, I am very honored and very happy to have such an opportunity to discuss our joint design.

Our society is not directly sensitive to the automotive industry, we are one of two providers, I would like to take this opportunity to discuss the Dell Inspiron 1150 battery concept of second supplier of polarization. Our company mainly include energy, materials, chemicals, real estate. Energy, the former Degussa to cover the company, we now expect to win record of the chemical company, we have listed here, in 2008 the market share of sales, you can see the chemical companies, sales s ‘raised to 11.5 billion euros. Can see that the traffic and machinery accounted for 18% of market share if this amount is not easy to be ignored.

Look what winning sales record in China in 2003, we established offices in China, we have 20 years of specialty chemical manufactured in the experience of China. Not only are our products is very important and we attach great importance to R & D work, for example, total investment in R & D Center in Shanghai has exceeded 20 million euros. We are in Shanghai Chemical Industry Park has also established a number of basic units of production companies. We also attach great importance to China and other Asian markets, customer service, win record in Greater China to have 18 companies around the Buan Qiu, Changchun, Chongqing, Dalian and many other important places. The spokesman stressed that before a large number of global problems facing us now if you look at the left side, we see that the world hp 417066-001 battery energy consumption is still increasing. A look on the right, in the crude oil production has peaked. Therefore, we must take various measures such as improving energy efficiency in the use or development of certain alternative energy or other energy to solve the problem. If we do not, we will eventually be faced with such a problem, there will be a depletion of oil resources, but also will mean a sharp rise in energy prices. Possible future can not afford such a high price of energy. For the government, they have a particular emphasis on energy saving environmental protection.

Currently, our customers, that is, to our car buyers, and now they prefer to buy low power consumption and less emission of carbon dioxide from vehicles. Look to the possession of a Chinese car is gone, take a look at the vehicles owned per thousand. Looking to the year 2015, we per thousand vehicles will be owned by them and the case of Germany is very similar. At the same time in this graph we can see the demand for crude oil. Demand for crude oil is a very important aspect, because the depletion of crude oil may occur in the future. So here we have to use alternative energy sources, the use of alternative energy vehicles to meet our needs. This includes electric vehicles, vehicles or using the Laptop battery or other hybrid vehicles to satisfy demand.

Look what the weight of cars, we can see the weight of cars has increased, mainly due to a variety of reasons causing the problem. They have developed a number of aluminum chassis and aluminum body. Handrails, beams, etc., etc. also need a better equipment. To reduce noise impacts, the need for better sound insulation system. At the same time, customers should be more decent, more cars. Better handling and tire grip, we need a more rigid chassis and design. There are other factors, like a big engine, transmission more complex and so on. We need a bigger engine, better brakes. All these will wave our cars more and heavier.

When it comes to electric vehicles when those vehicles electric vehicles will become more complex, because your car will need a sony VGP-BPS2 battery in the morning and many of my colleagues have talked about how to improve the efficiency of transmission. For our mission if we look at things from the left to see right back on history we can say in Europe, compact type vehicles, the Chinese are not the same. At the same time you can see the emphasis on lightweight compact car. As can be seen that the typical model in Europe focus more body and steel chassis. In luxury cars and sports cars, they stressed the aluminum body and chassis. For a small minority of emphasis on body technique and structural aluminum frame. 2015 to 2020 period, we focus on the structure of the body and hybrid composite sandwich structure of aluminum frame. Therefore, we will adopt the new materials to reduce body weight. If the use of lightweight materials, we can still maintain a great body, but its weight can be reduced. This large extent, to win in this area launched by startup companies focused on innovative materials, the program will play a very good results.

Look what we have the lightweight design of the first step is to replace the panels and windows. We can use the sandwich to replace the steel structural components in line with the S & P pieces. You can replace the roof material, the use of composite sandwich to replace the existing roof, replace the engine cover, engine doors and car doors. We can also use it in the car toshiba PA3284U-1BRS battery body, therefore, can make us a more nimble vehicle weight.

Look at the design of the body, the body design, composite materials can also be used to achieve their optimal weight, for example, the external parts in the body. We can use more complex components to reduce the number of functional integration of components. I hope we can listen to understand what I am, but it is not part of the exchange, so we can see part of the project design is very important. So I repeat, have a better design component can reduce the number of functional integration of components. For example, we can integrate the structure of anti-collision, we can simplify the equipment. In the meantime, we can use carbon fiber and epoxy foam, which can reduce the weight of at least half. We are the engine in the engine, you can also use some innovative materials. Here, we have experts Evonik. At the same time, it is also a process of injection molding process allows for high volume, the surface is very smooth to reduce friction. Of course, we also have a window innovative polymer, this window of polymer is very comfortable, the windows of the aircraft is to use windows polymer, very comfortable good impact resistance is also very good, and no debris. In addition, its apple MacBook Pro 15 inch battery security features are particularly good, if there is a rock above the windows, and will not be any debris, so it is very safe. If you use Windows polymer, the weight can be reduced to a large extent, can be 40 percent lighter than glass, so you can reduce carbon emissions can also improve its dynamics, but also a large surface can change windows to reduce reflection and blocking off the wave aspect. It is also the wear resistant coating and is resistant to scratches, these are the characteristics of polymer windows. Its process can be adapted to a variety of volume production needs.

Then, take a look, if we use the composite sandwich, then we can make other effects, for example, may lead to the same light organ, even to the extent of an ultra-light, because in which it will use the ring oxygen and carbon fiber structure and fiber composite sandwich this material compared to steel, can save 60% to 70% by weight, while resistance to collisions is also very good. It is a very good crash performance of Aspire 3000 battery crew members inside will cause no harm, mainly because he used the material is very good with very good performance accident. It also has other effects. I think that car manufacturers and car buyers, these are some very good option.

In addition, its production process was car mass production. If electric cars, I think we can consider them in electric vehicles use this material because it is ultra-light, and can provide a very light body, and you’re also very comfortable. Here you can see that we are composite structures built in the best connections. Here we can see that this type of composite material parts of structure can be used in front-end modules, roof, door modules or the trunk of the car door, it can also be used in the metal between the adhesive is very good. At the same time, can reduce weight and cost. We can see that if the use of such structural composite parts. It is a combination of some very good at the same time, it is also very comfortable, very smooth. We, as a secondary supplier. We can see that there are materials for use in our program to win a demonstration of creating and testing cars. Here you can see, we can test the top of the map on the right is the right test of lithium batteries. We found that the Dell Inspiron 8500 battery has a very good power. This is the highest speed can reach 150 km. Of course, that the machine is 22.2 kilowatts of capacity. The very moment, there are other tests, for example, if you use lithium batteries, even electric vehicles, he can still run very fast, we left you can see a wide variety of test vehicles. Can see that electric cars and hybrid electric vehicles. You can see in these vehicles, we are used to display in front of these materials. We see that these vehicles to achieve 260 horsepower, but fuel consumption is very low. But the rapidity of its effects is particularly good. Therefore, we can see that its performance can be incorporated into the driving experience. At the same time, you can also see where the hp Business Notebook nx7400 battery, it weighs only three pounds, it is not particularly burdensome. We have also developed a corresponding lubrication equipment, vehicle use low-friction lubricant testing and its effects are particularly good.

Then you want to summarize. You can see that now, because a shortage of crude oil resources, and force if governments and the automotive industry to develop a number of new energy vehicles, while fuel and energy efficiency has increased significantly, will design car itself has a character change. Today, the powertrain, body, energy storage and the chassis design to achieve energy efficiency in many gaps still exist, there is more space can be developed. Lightweight powertrain is also an important issue to reduce carbon emissions. Of course, this lightweight design is very important, this technology for electric vehicles for urban transport in terms of short, very attractive, but the battery size, weight and cost is a huge challenge. Similarly, acceleration and driving the course, lighter body and chassis, it needs a smaller battery lighter and less expensive. In addition, the structural parts of composite technology can help us achieve the quality of thinner, lighter and lower costs. Today, I give you new ideas on the screen, I think for small businesses and original equipment manufacturers, some new opportunities, we know there are OEM, they are very small. I think that these small and emerging companies can take our equipment.

The data show that the United States, the number of laptops sold more desktop in the number of notebook market in China is also growing. With the growing number of laptops, all sorts of problems on laptop computers one after another. The novice computer that does not know much, the Laptop battery is a precision machine exposes all the issues themselves do not know where to start solving only other advice or sent to repair. Here, Xiao Bian sorted on the novice May have questions and answers for reference purposes only.

Q: After buying this again on the screen and the layer of plastic film can Jiediao Mody?

A: This layer of the plastic object main mold is to prevent the laptop during transport and display LCD screen has been scratched or dirty. Buy home, there was nothing – because the picture quality will not only affect the thinking, as long as attention to the usual habits and maintaining a good image on it.

Q: The screen is dirty how to clean it?

A: If there is only dust, but no other quality treatment, then you can first try to blow the dust, then the reuse of a soft, damp, soft cloth to wring dry, if not water may flow along the surface of the screen was damaged ignition coil. For oil, or more difficult to remove stains can buy 40Y6797 special cleaning remove LCD screen, remember there is no quality assurance not to use a cleaning agent or corrosive chemical composition which will affect the screen.

Q: So how clean the keyboard is dirty?

A: The surface of the keyboard only cleaning with a soft damp cloth can be. For the keyboard, the dust on the substrate must be cleaned to remove the keycap 11. With the flathead screwdriver in the corner keycap a lever slowly upward, keycap can be taken down, but when the keycap to take action must be careful not to pry off the keycap or stent.

Q: Why is the screen of my laptop on the lower part of the darker side that some of them?

A: The notebook LCD lamp backlight LCD on the back, while the brightness of the backlight is directly dependent on the number and brightness of the lamp. The number of desk lamps at least two LCD plus screen brightness and even six lamp. The laptop is the power consumption and size constraints, only a lamp and smaller, multi-positioned in the middle of the screen depends on the position. A limited because of the lighting, so that the bottom than the top of the screen Shaoan. While the contrast is not great, are normal.

Q: The new battery for the first time when you need to use the same charger as the phone 12 hours Mody?

A: The circuit design of notebooks as the number of mobile phones improved, and almost no memory effect. However, like the hands of the Dell XPS M140 battery factory to the user that there is a lag, to allow a new battery can be in a better state to work, activating the battery and the work of ‘calibration is always necessary to do so. They do not need to wait a certain load for 12 hours because the battery, once full, circuit protection Internal battery automatically stops charging after full charge is unscientific and has been no practical importance.

Q: Why my battery does not use electricity has fallen?

A: Because the absolute humidity and not isolated, environmental impact, the battery consumption of all it is a natural phenomenon. According to recent experience and the quality of the battery every three to four days from about 1%, as not all belong to a significant decline in a normal phenomenon.  

Q: When you use the power does not remove the battery, it will accelerate the depletion of the battery?

A: In general, laptops are designed to load at least 95% of electricity will be charged, but the hp Pavilion dv8000 battery itself will naturally wear, then remove or not remove the base are the same. If she is deported, I suggest not connect too frequently. Caused by interface problems. In the long term without the battery, the battery must be wrapped in the membrane of fresh and placed in a cool, dry, and I remember a month or so used at least once the battery and charge the battery in order to avoid loss of activity.

Q: Why does my fan switch in the trunk when no reflection of what?

A: The laptop has its own temperature control, if you turn the fan stops spinning after self-test. Only when the machine reaches a certain temperature will accelerate the rotation. So when you heavy work such as reading decoding broadband video, 3D games, they will see the fan spinning at high speed.

Q: Why use batteries when the screen is sometimes given a slight creak?

A: When you use the toshiba PA3191U-3BRS battery, portable power-saving features will play a role. At this time the voltage is in the notebook evolving through the screen flow coil ignition coil are evolving, when its high tension ring for the issue of conversion. If the laptop poor electromagnetic shielding, the user would have heard such voices.  

Q: Why should I book a connecting part of the LCD will be fever, not the quality problem?

Answer: For this part of the heat that we should not be too nervous. Because of the ignition coil laptop LCD screen almost all placed in this position while the ignition coil is a major element of the circuit and the supply spool. Circuits and electricity when the work will be heating coil, it is normal.

Q: The battery is not fully used to the load is reduced life expectancy?

A: The battery is fully charged, depending on the number of computing life expectancy, we use lithium batteries are generally 300-400 times. Of course, you do not have to worry about the power will be connected to recharge the apple MacBook 13 inch battery once. In fact, the cycles of the battery usually only when the accumulated 80-90% of electricity will increase.

Q: The device can be converted to another system?

A: Many new laptop users are asked this question. System of the laptop was not operating under dead and desktops, as in the case of a driver support, you can install any operating system.

Q: My laptop is a P4, but why the feeling is slower than many of the same office?

A: The main reason lies in the hard disk. Now the mainstream of regular laptop hard drive speed is 5400 rpm, while the computer to pass the current minimum is 7200, when the hard disk is limited overall performance of a critical material , so compared to desktop machines to slow to slow in the disk drive.

Q: The charge and discharge frequent Mody may damage the battery?

A: Although there is no lithium batteries used in portable memory effect, but the frequent charge and discharge of their lives are still affected. Usually less than 10% as much as possible after the re-pricing power the TravelMate 290 battery life is conducive to growth. But if there are special needs, and sometimes charge ahead, its impact will not be too many.

Q: long without the battery, it should save it in what state? The need for ventilation of the battery?

A: The defense saved or at least put the shell is not correct. If you are a time not to use lithium batteries, should include in its capacity of 40 ~ 60% saved, this state, the discharge of the battery is relatively slow, and can be stored for long periods.

Q: Sometimes after accidents laptop, there is no way to simply remove the battery quit. Is that mistaken?

A: This approach is obviously very harmful. Because in the waking state, the memory is switched on and working, if the rash to take the IBM ThinkPad T60 battery is directly related to waste a lot of data, not in the socket when the AC adapter to take the battery, a This approach can be a hundred or harm anyone’s interests.
