As the electronic product industry is in the process of fast developing, we have witnessed great changes occurred in the whole market in terms of both laptop hardware and software. To be sure, with user requirements improved, the software technologies have got great revolutions, which have increased the requirements of laptop hardware.


Actually, the competition of electronic products is sharp, including the magnates of iPad and Windows system. Recently, it is reported that Microsoft will release its new 2012 version with MS office for iPad. Of course, each component should cost 10 dollars as the production cost, which has very good competitiveness with Keynote, Pages and Numbers of iWork in application price.

It is reported that iPad can be compatible with Office 365 online service and Office Hub service provided by Windows Phone platform. As to the news, Microsoft hasn’t got direct response towards this the business revolution. They said that they have got several platforms and devices for Office software and being devoted into future development with more useful information shared.

Office for iPad is supposed to be released in 2012. So are Office for Lion and Windows 8 system. Under this circumstance, our laptop computers need to get some upgraded laptop power supply and lithium-ion battery to support the laptop computer well. We need to improve the battery life, capacity, stability and other security protection circuits.

It is evidently that the hardware industry is confronted with great challenges since the laptop software has improved the technologies with upgraded primary materials and internal structure. That is to say, it is not for further requirements but the basic characteristics to ensure the updated laptop computers to work normally and rapidly enough. It is really a great challenge to laptop power supply and lithium-ion battery to improve the performance and technologies in a short period.

As to the laptop battery, many insiders have diverse viewpoints towards its functions and development tendency. In all aspects, we have got different kinds of discussions, including compatibility, contact, lithium-ion cells, protection circuits, secondary protection and so on.

Under this circumstance, we have got some researches on the laptop batteries in the internal structure and customer requirements. As a matter of fact, different manufacturers have different technologies in the process of design and production, which will be different in sales price and actual performance as well.

Security, performance, laptop battery

Speaking of the internal structure, laptop battery is composed by Grade A premium cells, fireproofing shells, protection circuits and other accessories with relevant circuits. Although the key part of laptop battery is the lithium-ion cells, other parts have also got great significance on the security, durability, compatibility and other performance characteristics as well.

Actually, not all the laptop batteries in the market are brand new and being with secondary protection circuits inside. After all, it will cost more time in design and production cost. However, just in case, we should prevent our laptop battery from short circuits and broken.

Except for the specific parts, the tests and other examinations are also very important to check the battery performance. Even if all the accessories are fully prepared before leaving the factory, it doesn’t mean that certification and examinations are in vain. Workers have tested it on the original laptop computers and imitate all sorts of operations by terminal users with some relevant devices.

All in all, the customer requirements are always the direction and resources of the industry future development tendency and examination ways. To serve our customers better and better, we will devote ourselves to complete these tests, select high-end primary materials and design specialized according to our users’ requirements.

As to laptop, tablet computer, many kinds of sayings have existed in the market about the development tendency and market share in the near future. It is evidently that the standby time of lithium-ion battery is regarded as the decisive factor that can influence on tablet and laptop computer to the great extent.

battery, standby time, tablet computer, laptop

Since the tablet computer has been born, there’re many options towards its future development while they are said to be hard to substitute laptop computer. Whether it is true or not, in my point of view, either laptop or tablet is different from each other in requirements and functions.

Although in this black Friday, flatscreen TV has surpassed many other hot electronic devices to be the most popular gift, it is inevitable that portable electronic products are bound to the necessities to many businessmen, personal users and other relevant customers. If so, the most urgent issue for us is to make them more conveniently in durability and portability with reasonable sales price.

With time goes by, the sales volume over cell phone has also improved very rapidly that we can get more from portable devices as we can carry them out in business trip or on our commute every day.

For this reason, tablet computers have more advantages than laptop, especially for Sony Tablet that is more light and handy than iPad. Meanwhile laptop computer, except for netbook, is not so convenient if we need to take it away as an essential item.

Speaking of portability, there’s no doubt that lithium-ion battery for tablet computer are necessary for users to consider if we need to rely on it to complete enough business tasks or deal with more orders, pieces of documents and entertainment.

Under this circumstance, high-performance extended life battery is the must to the whole electronic device industry and battery chemical industry. After all, too heavy and large batteries are obviously unconscionably in the future.

With the Thanksgiving Day goes by, the Christmas is closing and closing to us. At this moment, have you ever considered about your own Christmas gift? According to the report, iPad is regarded as the most popular product that most of people hope to get as Christmas gift. What’s your answer, tablet or laptop computer?

In the last year, people are just wondering how much tablet computers can bring to us even if iPhone has occupied a large market share. As the magnate of tablet computer industry, iPad has developed very rapidly more than relying on the background of Apple. Nowadays, iPad has become an indispensable electronic device in our daily work and regular life that can be used to browse the Internet sites, send emails, see movies and anything you want from the tablet computers.

tablet computer, laptop computer

Even so, laptop computers are still the main tools to complete our regular work and some complicated tasks, such as establishing some programs, having some business documents, dealing with some orders and so on.

Although iPad and other tablet computers have larger and larger market share at present, they still cannot substitute laptops in the market. After all, we are used to rely on laptop and the actual work is hard to be changed so rapidly according to current technologies and requirements.

However, as a gift, what’s your final choice in this coming Christmas Day?

Tablet computer is regarded as an extra product that is not the necessity device in our actual work while it can bring us more about imaginations if it is a Christmas gift. To be sure, although it hasn’t got so many real powerful functions at present, more and more people are eager to get one. Many promotion lucky draw activities have made iPad and iPad2 as their final gifts since the early of this year, whose results have shown us the influence of tablet computers obviously.

On the other hand, laptop computers can also cover the functions of tablet computers if they are conveniently in portability, especially for Apple Macbook Air series.

Therefore, it is really hard to make a choice between laptop and tablet computers faced with fruitful Christmas gifts. Anyway, your requirements and selections will also influence on the development tendency of the market situations of next year.

Solar batteries have experienced great developments, however, they have been confronted with great challenges recently. Especially in the industry of PC, lithium-ion batteries have supplied the largest market share at present, which has given solar batteries great threats as well.

It is known to all that lithium-ion batteries have got great revolutions in last time and other performance according to the industrial report. That is to say, after having used such limited laptop batteries for a long period, it is time for us to get a much more powerful laptop battery from now on.

lithium-ion battery, solar battery

The merits and demerits of solar battery and lithium-ion battery

Comparatively, solar batteries are not popular in the market thanks to all sorts of reasons, including high production cost, high technologies, user requirements, and so on. Lithium-ion batteries, as the main power supply products, have supplied the most market share come down to laptops, digital camera, cell phone, etc.

It is certainly that solar batteries are convenient in use as it can be carried out and being charged and discharged very easily. Furthermore, the power energy can be stored much more and these solar versions can be compatible to many laptop models that are regarded as universal batteries in some cases.

If the lithium-ion batteries have been improved in performance, it means the merits of solar batteries in power capacity have been substituted to some extent. If solar ones cannot get some other powerful merits in portability, compatibility and other aspects, it is very likely to be replaced by lithium-ion batteries in the near future.

Evidently, since Ni-cd and Ni-mh batteries have been marginalized, Li-ion batteries have won great market share for many years while they are possible to be the king of laptop power supply industry for another many years according to the current technologies and market situations.

Since tablet computer has been released, the PC industry has been confronted with unprecedented challenges from the whole market while it is time to have some development in technologies. However, another problem has occurred to us between low consumption and high performance as to laptop computers.

Realizing that all the users have higher requirements with time goes by, they require more from the laptop battery and laptop charger thanks to larger internal memory, updated system, higher consumption and other increasing demands.

laptop battery, low consumption

Under this circumstance, laptop batteries have been improved in standby time with more lithium-ion cells installed inside. However, the consequence is that the laptop battery has become larger and heavier that is not convenient in portability. So is the laptop charger. To improve the output power and security factors, some other accessories like overheating protection circuits, indicating system and others have been added inside to keep the higher rate charger working under stable conditions.

In addition, the high consumption has also increased the influence on our environments while some environmentalists have some dissenting opinions towards such a powerful techniques and high performance from laptop battery and laptop charger.

As low consumption and high performance seem to be hard to be met at the same time, especially according to the current techniques, we need to get balance or choose the final and most important factors to laptops.

It is gratifying that lithium-ion cells are going to be updated to some extent thanks to the revolution in electrochemical properties by some professors, which is said to be realized in about 5 years. Although it is proved to be well in theory and laboratory, it is unknown if it will be substituted or stably in actual work.

Therefore, if high performance or low consumption is still a uncertain topic to laptop battery and laptop charger at present, which has promoted the development tendency and future situations of our PC industry and even other electronic products like cell phone, tablet computer and so on.

One of the most important things to human beings, especially to those who run organizations, companies, institutions, and etc, is, as we all know, to learn to know how to operate a computer that is commonly used items in many areas today, in that almost anything you know is run or made by computers. Cars and jets were designed on computers, traffic signals are run by computers, most medical equipment use computers and space exploration was started with computers. Most of the jobs today require the use of computers whose 'mechanical brains' have a huge impact on our society. It would be hard if we didn't have the computer around. It is obvious, therefore, that the main trends of computer development are ‘getting smaller’ and ‘enhancing speed’. It is practicability and universality that empowers computers to be deeply imbedded into our daily lives and most fields cannot research without them. In other words, computer techniques expedite other subjects and consequently affect on human progress.

laptop, tablet computer, desktop

Let's visualize for a minute. Let's visualize a world without computers. People in the medical field wouldn't have found a lot of cures to diseases without the help of computers. Movies like Jurassic Park, Toy Story, A Bug's Life or Godzilla would never have been made without computers because they used computer graphics and animation in them. Pharmacies would, without the use of computers, have had a hard time keeping track with what medications to give to patience. Counting votes would be impossible without computers and most importantly, space exploration would be impossible without the help of computers. It's a pretty tough life without computers, in a word. Some may not agree and say, "Well, we don't need computers to live on." They maybe right but mostly, they are wrong. Computers help in curing diseases, create more entertainment for people, keep track of important records, and etc. Without computers, all this wouldn’t come true.

Trends in Computer Development

The main trends of computer development are ‘getting smaller’ and ‘enhancing speed’. Getting small is not only size but also the consumed power. As we know, resources are getting less, so saving power is really necessary. Some people say it is equated with saving capital. Other people say that running a laptop computer can run away with a lot of batteries. For personal laptop computers, if the consumed power is low, it means you can use your computer for a long time without changing the battery. The development of saving the power of computer and enlarging the content of the battery benefits some people who have to use their laptops in different places and don’t want to carry chargers. Enhancing speed has two meaning. One is to accelerate the speed of processing. For example, we can run lots of programmers at the same time and it will not break down. Another one is enlarging memory, which is to increase the space of saving data and transferring data.

The above paragraph is about the trend of hardware development. The following is about software. It has two aspects – operating system and application software. The operating system likes a layer to provide conditions for the application of software and connect to the hardware. Even if the hardware and software have enhanced perfectly, without an operating system they cannot work together. So operating system plays an important role in software. The application of software is associated with our daily lives. For instance, MSN is quite useful software and a more popular chatting tool on the Internet. By using it, we can see and talk to others wherever we are.

When the cell phone has played a more and more important role in our actual life, it is obviously that mobile location has been taken full advantage in all aspects. We can learn about the surrounding stores, services and anything we required by mobile location. Comparatively, another portable electronic product laptop computer hasn’t played so well in this way.

Since 3G network has been popularized in the market, especially for tablet computer, more and more users begin to enjoy the new emerging fast running network and service. Compared to the past situations, we just don’t need to play with our laptop computers with fixed location, which has brought more to laptops.

Mobile location, laptop computer

Certainly, such a new technology mobile location has already been used by cell phone and laptop users to some extent. The mobile IP address can bring us more about our life surroundings, relevant information, e-maps, and other urgent items. In search engines, users can get some more accurate results if the robot can catch our portable IP address intelligently.

It is certainly that to improve the functions of laptop computer, standby time of laptop battery is a key point to determine if we can extend it enough. That is why cell phone has surpassed more time to our daily life while iPad has increasing its sales volume even if it still cannot substitute laptop computers in core technologies.

According to BBC, lithium-ion batteries have got great revolution recently while the standby time is possible to be increased by 10 times in about 5 years. If so, we can not only play with laptop computer fully for a whole day but can work without AC adapter regularly. If any customers need to work or have entertainments with laptop computer, laptop battery won’t be a limitation any more. Such a technology will also be applied into tablet computer, cell phone and other electronic products.

There’s no denying that any merchant or manufacturer can no longer ignore the development rate of cell phone while mobile location is regarded as core competitiveness. Faced with such a great competitor, it is time for laptop computer to improve according to updated customer requirements.

Recently, the problem of iPhone 4s has come down to all aspects while the most significant part is related to lithium-ion battery standby time. It is known to all that users usually don’t have enough standby time if they have got an iPhone 4 or 4s. However, according to a professional test, the root cause is not the lithium-ion battery but internal programs of cell phone.

Iphone 4s

It is reported that the production cost of iPhone 4s is about $199 while the lithium-ion batteries are regarded as one of the cheapest part inside. As a matter of fact, the core value of Apple doesn’t rely on the battery or lithium-ion cells technologies but other accessories, such as touch screen, chip and so on.

As it is relevant to chemical science, on no account can we put the lithium-ion batteries together with other hardware in development rate, standby time in particular. The only factor that we can improve refers to stability, compatibility and security.

In the past, some accidents about Apple products explosion have occurred in Japan, which is led by lithium-ion cell phone battery. That is to say, if we cannot ensure about the important basic characteristics, longer standby time is still in vain.

After installing the new iOS 5 operation system, iPhone 4s is of high consumption while it can last for nearly less than a whole day. According to Apple, the problem is possible to be related to system bug and some programs can solve the problem to some extent.

Nevertheless, an unknown iPhone application developer has reported his test on iPhone 4 and 4s towards the lithium-ion battery and standby time. He told us that the root cause is the software and cell phone configuration instead of any hardware.

He has had experiment with two iPhone4S, one for regular work and another for test. These two phones are purchased at the same time from Apple official store and taken advantage of AT&T network with iOS 5.0.1 system. However, the result is that the one hasn’t installed the new program inside has run into battery problem in the battery indicator while another hasn’t.

It is obviously that iPhone 4s hasn’t got poor lithium-ion battery even if it is not high in cost, technology and short in standby time. The fact is that software and system bug should be improved in time by Apple that can recover the whole iPhone from difficult positions.

There’s no denying that many large brands have run into some accidents in their lithium-ion laptop batteries while most of them are caused by overheating. It is frequently occurred to internal circuits to be overheating, overcharging or overloading if we don’t have proper design in the protection circuit and other circuit boards.

lithium-ion laptop battery, protection circuit

It is known to all that lithium-ion laptop battery is composed by lithium-ion cells, protection circuits, chip board, IC board, fireproofing shells and so on. It is obviously that all these parts are important to ensure the quality and other performance of compatibility, durability, security, stability and other factors.

For this reason, our designers and workers have worked hard in the process of manufacturing with secondary protection design for the internal structure. As to the lithium-ion cells, different brands and specifications have got different quality and capacity. Except for cells, the overheating factors have great influence on the protection circuits and other parts.

Have you ever figured out that some laptop batteries have reduced the performance more rapidly than others? As a matter of fact, some of these batteries and chargers come to be very high in the work temperature even if they haven’t been used for a long period.

There’s an additional part that have been adopted by more and more manufactures and lithium-ion laptop batteries in the inner part. The heat filter and radiating fin are necessary to keep these electronic products working under good conditions instead of instability and overheating.

In addition, the precise internal circuits have also helped the lithium-ion laptop battery to transfer the power energy more smoothly with longer lifespan. On no account can be pursue for high profits without thinking hard about the quality of products in all aspects. Therefore, please pay attention to the work temperature and actual capacity in BIOS when selecting and checking the new battery replacement.

Have you got the habits that charge your cell phone, digital camera, iPad or other electronic products through laptop computer? It is obviously that most of users have ever charged their products in that way before while they seem to be not easy to operate but the lithium-ion batteries come to be smaller and smaller in internal capacity.

As far as output power is concerned, both laptop AC adapter and battery have got their own nominal values in output power, voltage and current. That is to say, even if the consumption rate has increased, the output power of laptop computer won’t be changed to be higher thanks to the limitation of capacity.

laptop computer

For instance, a standard 6-cell lithium-ion laptop battery is rated at 10.8V and 4400mAh. In most cases, it can serve all the laptop accessories well under normal work situations. However, with more electronic products are installed and plugged, running rate has to be divided into more parts while the actual output voltage and current is reduced in each part.

As is known to all the insiders, long-term overtime work is dangerous to all the laptop computers, lithium-ion batteries and chargers by overheating, overloading and overcharging.

After all, we cannot get direct pure output power energy from laptop system as it is a complicated electronic product. If we charge our tablet computer, cell phone and other external devices on the computer every day, the lifespan is likely to be shortened by a half.

On the other hand, when the output power is separated by more programs and devices, the running rate of motherboard and internal memory will be lower and lower. To be worse, if the internal resistances of lithium-ion battery and charger are increasing, the conditions will be more dangerous so that the laptop computer is hard to support well with these devices and even internal parts and serve with enough power energy.

If you have to do like that, we recommend you to keep all the programs off or enter into sleep mode, which is of less dangerous. It is certainly that the best way is to charge these electronic products by compatible laptop chargers. If you need some compatible or original chargers for laptop, lithium-ion batteries for laptop or digital cameras, please feel free to contact with our servicemen.

Recently, the PV industry has run into great challenges seriously while it is supposed to be an unprecedented predicament to the whole industry. Especially for manufacturers, the high production cost and unexpected profits have protected them from producing more solar chargers.

solar laptop

The senior analyst of Solarbuzz has got a stupendous speech in a global PV industry of 2011. He said that we are facing with a PV industry on the simmer relevant to the issues of the whole industry chain.

At present, we are having researches on the current supply chain of PV industry, from polysilicon, silicon wafer to batteries, modules and other relevant devices. It seems that the requirement increasing rate has kept in a certain value while solar chargers are not of mass production in the market. Comparatively, the decreasing requirement rate has brought us great challenges from now on. Someone has doubted if solar chargers will weed out from laptop accessories.

The slowing demands have become more and more evidently with time goes by. Last year, a great rapid increasing has occurred to PV industry while many more manufacturers and enterprises have come here to take part in the supply chain. For this point of view, it is led by excessing production capacity instead of short demands. The increasing rate of production has already surpassed the increasing of requirements in PV industry to a great extent.

According to the analyst, the development tendency of polysilicon batteries and modules has shown us the situations of 2012 and further future according to the industry report, which has increased the pressures of solar power products thanks to the cost of manufacturing, design and factories establishment.

In my point of view, as long as solar chargers have improved the demands, the crisis can passed away sooner or later. It is still an unexpected issue if solar chargers will weed out or not.

We used to endure many functions to laptop computer and accessories before to meet the increasing requirements. We hope our notebook can be more conveniently, endure more data and realize more amazing functions. Under this circumstance, have you imagined if our laptop charger turns to be intelligentized?

Recently, since Apple has released their new product iPhone 4s, many insiders are talking about Siri, the new personal speech assistant. It is said that such a new function can substitute human beings to some extent steps by steps. Actually, Apple has become a symbol of the whole industry in development tendency and technologies.

laptop charger, ac adapter, intelligentized

Comparatively, except for output voltage and current, there seems to be little different and change occurred to laptop charger for a very long time. Such situation has great influence on consumer electronics and laptop computers while researchers and scientists have try all the ways to realize those illusions.

When the laptop AC adapter is able to learn about the requirements of laptop system automatically, the internal circuits know how much power energy is needed and the charger adjust according to motherboard work pressure, internal memory space, work temperature, battery capacity and other relevant factors.

Just like sleeping, this kind of new laptop chargers can also realize self-renovation and charging similar to human beings. And it has learned about the social work principle and can be adapted to different work conditions gradually. In addition, if it can no longer rely on the external power supply, it will be more conveniently, such as universal, solar and worldwide compatible AC adapter. These intelligentized power supply chargers will bring us a new start of the industry that can get us rid of the ties from outlet, socket, temperature, system, running programs and other elements.

In daily work, there’ll be many sorts of problems occur to laptop battery and AC adapter before we have figured out them. In this aspect, we need to find out the root cause before taking any action to solve the problems.

In some cases, the trouble is just temporary that is likely to be led by heat, overtime work or some other accidents. As to thus problems, it is simple to solve by removing the dangerous work conditions, activate or repair according to some maintenance tips.

laptop check

In most cases, the problems are not so easy to solve directly while some users are confused about the symptoms and root causes. For this reason, some items users need to pay attention to before making decisions on replacement, backup, repairing or other reactions.

To check if there’s something wrong with the laptop AC adapter, we recommend users to take the lithium-ion laptop battery out and restart the computer. Of course, before operate, please ensure if you have powered off. Otherwise, if the charger has come across some problems, you will lose some important data stored in the notebook.

As long as you are able to work on your laptop and other symptoms disappear, it means the problem has happened to lithium-ion batteries only. You need to select a suitable high-quality new battery replacement. If not, let’s get to the battery to have a further check.

With the same operation, please unplug the laptop charger connector tip before charging the laptop battery for about 3 hours at least. Then check if the battery can serve and support laptop for long enough standby time while the symptoms have run away.

To be sure, all the assumptions can only be realized before you have figured and thrown away the temporary troubles that have listed as above. After all, even if both laptop battery and AC adapter are under normal situations, the problems might exist in the process of use.

The science and technology have gradually influenced on our daily life by more and more additional functions. Since PC desktop computer has developed into laptop computer, it has applied into many extra functions in terms of laptop system, power supply, internal memory and so on.

batteries for laptop, laptop charger

Nowadays, hardware doesn’t play a simple role any more in actual work while it comes to be more fruitful, such as indicating software, battery management system, power energy saving mode, protection circuits and other new options. If you have compared the brand new versions to old ones, the difference is obviously and they have made our work on computer more conveniently.

With time goes by, our chargers and batteries for laptop have become more powerful in supplying output power and stability. That is to say, with more additional functions have been added, the development tendency of laptop accessories in the near and further future is going to be multi-functional while they will bring us more and more amazing results.

There’re some potential and possible development tendencies for laptop accessories, especially for laptop battery and laptop charger.

At present, the primary role for laptop batteries is supplying power energy according to OEM specifications. However, many users seem to be not content with these functions while they hope the indicators are also installed in the batteries for laptop with remaining power energy, rechargeable cycles and other relevant information on the battery shell.

On the other hand, laptop charger is also going to be more interesting. Solar chargers can also substitute the batteries as they can also be carried out flexibly. Some universal AC adapters are very welcomed in the market that can be compatible to many kinds of laptop computers while we need only some unique connector tips as backup or replacement.

Anyway, the new updated laptop accessories are developing according to user requirements and consumer electronics status. To improve the performance, primary materials and internal circuits design are the core values to determine if they can meet the final satisfaction.
