We often use the laptop will produce some errors, the following list I would let you use the laptop battery a few mistakes, and I hope everyone is in use in time to avoid.
1. Full power to unplug the power
In the notebook computer battery is fully charged circumstances, should no longer be using a laptop computer external power supply. Because in the case of loading the battery using a laptop computer, in fact are in a re-charge the battery when the use of the state. In addition to reducing the battery life of things, using both AC and battery, the machine can also cause overheating, it is very easy to damage the other components.
2. A long time do not use the battery
While connected to an external power source should not use the Latitude D830 battery , but a long time without using the battery approach is also wrong, the need for regular battery capacity to activate the appropriate use appears to be more accurate. In particular, each time when you should pay attention to the use of the battery re-charging the battery runs out, but try not to without full power, unplug, have already been filled with power, it should be a separate battery or power adapter and not be shared use.
3. Often the battery discharge
Do not remove the battery often, nudity battery position, this large amount of dust caused by easy access when using the VGP-BPS8A connection is bad, the battery should be noted that when the demolition dust waterproof moisture shock, regular position at right with a small brush to clean.
With the increasing popularity of notebook computers, notebook computers on all aspects of the problems cropped up in various media on the largest number of arguments the proper use of laptop batteries, notebook batteries some articles say that the use of personal experience, while others claim expert guidance (which we often do these SALES), all kinds of stories are, the argument number.
The author is also a regular laptop user, although not an expert, but with many years experience in the use of notebooks, the author through a friend recruited dozens of university students using a laptop, so that they talk about their experiences on the use of laptop batteries Inspiron 6400 battery , Inspiron 640m battery , Inspiron 700m battery , coupled with its a little more experience, summed up what made available to the
We as a reference, hoping to give everyone a little help.
1, the argument 1: the activation of a new battery
● point 1: before buying a new battery inside, there will be more than 3% of electricity, more than the battery inside the power exhausted, until the shutdown, and then re-use an external power supply charge. Charging time must be more than 12 hours, repeated three times to do in order to activate the battery.
Point 2: No, the battery for 10 hours of rechargeable battery to activate the activity of the normal charge-discharge method for activation.
● Survey Results: The authors investigated and 24 college students laptop users, 18 is the second point of view, and that such manner and does not charge the battery for future use can hurt, of course, to exclude damage to the natural elements. The author himself is also the case when the normal use of a new battery for up to two and a half hours, now two years past, the status of the battery is still good, still can reach more than two hours, so I am afraid I have been satisfied?
● the proposed method: I agree with the second view, based on available information indicates that the activation of cell work should be completed at the factory, and laptop battery factory with a capacity of some natural wear and tear in order to avoid damaging the battery. Activation of the battery should be in no circumstances to protect the circuit can be with its own lithium battery circuit protection circuit, the purpose of this piece of the circuit is to avoid excessive battery charge and discharge, generally filled with the battery after charging when the indicator light off , the battery can not be recharged into the electricity, and then you then plug the power plug to recharge the battery in the face of what use? Available from the battery can be seen on the status of the battery have any charge, another teaches you a simple way to be able to determine whether there during the battery charging, battery charging, when the phenomenon will have a fever, when the battery is full after one hour (power plug does not pull), you go try the battery to see if the battery is still warm not hot? The result is definitely cold, because the battery is not charging and discharging state certainly does not heat. Notebook makers at the factory will propose that a new battery for more than 10 hours. This sentence may be generated for some users the wrong point of view first, the author of this opinion, should be taken into account that some notebook manufacturers a new user in the new battery charge when not fully grasp the skills, simply so that they can charge directly 10 hours, so this should be the business of expediency.
Second, the argument two: whether the external power supply unplug the battery?
● view 1: Use an external power supply when the battery removed.
● view 2: Use an external power supply is not required to remove the battery.
● Survey Results: Most students in the use of an external power source, will the battery removed, only a few use an external power supply when the battery is placed above, that the few brands are used by students in several international brand.
● the proposed method: In fact, if the battery is removed, the conflict focused on the use of an external power supply when the battery is charging to the issue
. We should know that the number of charging and discharging the battery life is directly related to the general lithium battery set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially modified products, but 800 times, once for each rechargeable batteries a step forward to retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only increase the number of charge cycles, but will also cause overcharge. The second view is that the battery is full power on the computer in the use of an external power supply will not recharge. In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individuals is not very comprehensive, after I investigated, many notebook manufacturers are taking into account the vulnerability of the battery, and the product added to the battery protection technology, and thus the corresponding different brand laptop batteries Charging protection technology is different, like some large companies do very well in this regard, such as: IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, IBM’s notebook computers can detect the battery discharge situation, ThinkPad notebook battery only less than 95% of the time will automatically recharge. This can play a very good protective effect on the battery, and now many other manufacturers have followed suit. So, like the battery, you do not have the time to use pull down, because only when the capacity less than 95% of the time it would charge. But even so, if you are prolonged use of computers, or will the battery be removed to compare the good, because the long-running laptop heat generated when the battery will cause some damage. However, some other “little brand” laptop batteries, may not enjoy such treatment, because it has not done inside the battery protection technology. I like to use a certain brand of notebook computers, if the fully charged battery on the above, when using an external power supply was confirmed when the first charge about electricity, because the battery storage, will have wear and tear, can not reach 100%, while not 100% as long as , power supply connected to the charge. Each access to external power supply is equivalent to charging the battery once, although only a small charge will be the time. Therefore propose that we use when the machine according to their own circumstances, look at the laptop manual, choose whether to use an external power supply when the battery removed.
Third, the argument 3: How to correctly charge?
● point 1: The battery power should always be all exhausted, so that consumption of notebook computers to automatically shut down and then recharge, each must be filled.
● point 2: when the battery is very deliberately not to pay attention to, and use when I wanted to charge to charge.
● Survey Results: The majority of students said that, unnecessary to the first view, as used in automatic shutdown and then charge, but also like the second point of view, it is free of charge. Are generally used when the battery needs charging when the computer prompted further charge, of course, prompts the time can be set, the default is to 3%.
● the proposed method: In this paper the proposed method with the majority of the students is the same. In fact, regardless of laptop use nickel-metal hydride or lithium batteries, these batteries are have a memory effect, and nickel-metal hydride batteries with memory effect is very obvious, but equally there will be lithium memory effect, but its memory effect smaller than the nickel-metal hydride Bale . There is no memory effect on lithium to say, only exaggerated and irresponsible business conduct in advertising, is totally misleading. Well, since the battery has a memory effect, it should be noted when charging point, as far as possible and then run out of charge, but do not have to deliberately say must use the computer to automatically shut down, so that although there is no harm in using them (because the laptop battery has a charge-discharge secure, laptop automatically shut down has not yet reached the standard VGP-BPS8A discharge protection), but you do not feel so tired? In fact, less than 3% of the charge in this way is very good, memories will certainly be the effect, compared to natural wear and tear, it should be nothing. As for the second charge on the charge to the view, the author is completely disagree, and have already said, whether laptop battery nickel-metal hydride or lithium, which has a memory effect, if in this way then the battery life will be shortened.
Jin Jing ultra-white, slightly higher quality, market share, but at nanbo under the pressure of competition, this advantage may disappear within a short period of time. In addition, ultra-white float nanbo expansion of production capacity can be greater than the Jin Jing.
At the next TCO (TransparentConductiveOxide, transparent conductive oxide coating) glass - thin film solar cells the key to the field of Materials, Jin Jing nanbo far less likely.
Because of technical difficulty, and thin-film solar cell manufacturers can not be all short-term self-coating, TCO glass demand is still vast, crystalline silicon cells enterprise competition for silicon material, the future is likely to reproduce the conductive film glass. Because of technical barriers and high TCO glass is expected in the next 2-3 years, the state of supply tight, prices high, strong profitability, suggesting more than 40% gross margin.
TCO glass nanbo likely to enter the field, laptop battery with the best coating technology foundation, the larger the probability of success, and Jin Jing currently do not have any production capacity of coated glass, in this area can not nanbo competition.
Jin Jing nanbo will more fully benefit from the development of thin film solar cells. At present, the corresponding shares in 2009 for the 19 times PE, and Jin Jing technology valuation in 2009 to 32 times PE, the former is relatively obvious underestimate. . nanbo view of product lines better and stronger ability to resist risks and the future in the field of thin film solar cells to benefit more fully, we believe that its valuation should not be less than at least Jin Jing, to maintain “overweight” rating.
