Pocket PC

Pocket PC is a handheld device that can help you store and retrieve e-mail , contacts and appointments , play multimedia files , and appreciation of electronic games , exchange text messages with MSN Messenger , browse the Web Content ... ... You will be able to with desktop Implementation of information exchange and synchronization . PPC, is the Pocket PC ( referred to as PPC), is based on Microsoft's Windows Mobile operating system, a handheld computer . WinCE Pocket PC using a series of systems developed by Microsoft . PPC also known as portable computers , is that most IT vendors to support a high-end PDA products , with full-color LCD screen, pen- input and so on. PPC, came into being , a great favorite of replacing the posture PDA as fashion . Manufacture of the famous Pocket PC manufacturers are HP, Dell , etc. . PPC said we should say that smart phones, smart phones The main difference is that it uses the operating system . Smart phone operating system is divided into several categories : iPhone, Symbian, Microsoft, MOBILE (SMARTPHONE and PPC are two platforms ), Linux, there PALM. iPhone OS or OS X iPhone is Apple's operating system developed for the iPhone . It is mainly used for iPhone and iPod touch . Like its Mac OS X operating system, based as it is based in Darwin . iPhone OS system architecture is divided into four levels : the core operating system layer (the Core OS layer), the core service layer (the Core Services layer), the media layer (the Media layer), can tap layer (the Cocoa Touch layer) . System operation occupy about 512MB of storage space. Symbian phones are the most abundant , and Microsoft Mobile (SMARTPHONE and PPC are two platforms) operating system more in line with the computer application used to . Linux open better . PALM has a number of FANS. Microsoft windows mobile smart phone difference between two platforms PPC, or Pocket PC, Microsoft Pocket PC -based system architecture , the most common PDA system developed by Microsoft , and Microsoft Pocket PC Phone is developed for Microsoft's smartphone operating system , the biggest difference between the latter Insert the SIM card can be used as cell phone use , and when , after pressing the power button can turn off the PDA functions , but can still continue to use telephone features . Software compatibility , there are also many are interchangeable. Most of the current market smart phones based on Microsoft operating systems have adopted this operating system . Pocket PC Phone and Smartphone is Microsoft 's smart phone development system , the two are similar , but different. Similarities , the two are the Windows mobile family of operating systems , are based on Microsoft 's Windows PC operating system evolved , so that their interface is very similar . While the hardware system, using Microsoft's smart phone systems generally use Intel embedded processor , a relatively high frequency , while using the operating system of smart phones in other hardware ( such as memory , memory card capacity , etc.) Than with other operating systems of smart phones to be much higher , the relatively strong performance , operate more quickly . However, this series of cell phone has some shortcomings , as a result of the high profile , multi- function caused by power consumption, battery life is short, use of high cost of hardware defects . The difference is , Smartphone based on Windows CE kernel development , based on the mobile phone operating system without the help of a stylus , simply use the phone keypad can be done to provide almost all of the operations, therefore , the use of the operating system of mobile phone users with one hand Operation can be , and Pocket PC Phone , you must be operating through the stylus , that is the biggest difference between two types of systems on the performance mode of operation . In addition, although are based on the Windows system, but in the application software are not the same .

Buying tips

What should PC do ? And traditional home appliances , " one-stop " thinking different purchase , PC the fast development of products with the configuration of the top high prices , but the speed is relatively fast computer upgrade . Therefore, users should choose according to their actual needs of the most reasonable in cost performance aspects of the computer . Technical indicators to see . PC manufacturers often have many products to Europe's largest direct computer vendor Tailai computer , for example, its product line covers the economic , professional, rich , top . Super Extreme and many other combinations . The user can select the specific model from motherboard , memory , graphics cards, hard drives , monitors , Modem 's configuration and whether it has DVD playback capabilities , and several other aspects . Do not forget to determine the size of the display screen . In general, the brand of the prices are 15 -inch monitor as the benchmark . At present, the 17-inch display has gradually become fashionable , in learning , Internet and even watch DVD movies when the 17-inch large screen display advantages become increasingly evident. So if less than 600 dollars plus the replacement of a 17-inch display will be even more icing on the cake .

Mobile PC Sony PCGA-BP1N Battery, Sony PCGA-BP2NX Battery,

There are manufacturers, mobile PC is also known as " portable desktop PC " , " home portable one machine " , which is characterized with a laptop with almost the same appearance, but no built-in battery , PC Card slot , usually through the exchange of power for Electricity, has strong portability , and the internal structure of more streamlined, more user-friendly self- promotion and maintenance . In addition, most models can be optional plug-in battery , enabling truly mobile computing. Mobile PC and notebook computer main difference is : Mobile PC accessories mainly used desktop accessories , and laptop accessories are mostly dedicated laptop accessories . 1, on the battery : Mobile PC generally do not have built-in battery, and powered by AC power supply , the latest mobile PC market also has built-in battery , but because of its use of a larger desktop accessory power , so battery The use of shorter, often causing crashes phenomenon , and the notebook is equipped with built-in dedicated 100% battery , use a longer time . 2 , on the PC Card slot : PCMCIA mobile PC virtually no support for a variety of interfaces , and a variety of PC laptops have expansion slots that can easily achieve a variety of peripheral products to connect . 3 , on the CPU and other main parts : mobile PC 's CPU is using a desktop CPU, and more for the P4 series, while the notebook 's CPU they use a dedicated mobile -based notebook CPU, the current mainstream notebook CPU is C4-M and PM Series . Mobile PC with integrated SIS motherboard is basically integrated motherboard , memory is also more common use of SDRAM, DDR memory, less , most of the hard disk has a small capacity of 5,400 rpm . The notebook computer CPU, motherboard , memory and hard drive are all dedicated . 4 , regarding the performance: mobile PC with a desktop machine parts , used in performance can not compared to dedicated laptop accessories . Although some mobile PC is also done in a sophisticated , but far to heavy notebook . 5, on the heat : moving the desktop PC thanks to the accessories , so more heat and power consumption , which is Mobile PC often causes crashes . The laptops are generally advanced copper heat pipe thermal technology , with intelligent cooling fan , an independent space for heat dissipation , to ensure system stability . 6 , on the price : As a result of mobile PC desktop accessories , the price is lower than the laptop , and notebook configurations with the mainstream , then the general price will yuan .

Interpretation of cell phone lithium battery charge Mistakes

Some friends in to theMobile Phone BatteryCharging, charging that the longer the longer the use of time, in fact, it is wrong. Let's look at the most commonly used in the original volume of lithium-ion batteries are generally used (GB/T18287 2000 specification),laptop battery the first constant current charging, ie a current will, while the battery voltage is gradually increased as the charging process, when the battery terminal voltage to reach 4.2V (or 4.1V), constant current charging to constant voltage charging change, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, that the charge Termination. (C is the control current of the battery nominal capacity of a representation, such as the battery is a 1000mAh capacity, 1C charge current is 1000mA,, Sony PCGA-BP2NY Battery, Sony PCGA-BP2R Battery, attention mA is not Ah, 0.01C is 10mA.)

Why do you think the charge end of the 0.01C: This is the national standard GB/T18287-2000 under discussion is arrived at. There used to be common to 20mA to end, the Ministry of Posts and Telecommunications is the industry standard YD/T998-1999 such a requirement, that is, no matter how much battery capacity, and stop current is 20mA. GB 0.01C contribute to charge under the fuller, right through the identification of a party manufacturers benefit. In addition, the national standard provides for charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours to, and also believe that the end of charge.

Therefore, the quality is no problem of batteries should be within 8 hours to reach 0.01C, the poor quality of the battery, then charge down meaningless. Lithium-ion or lithium polymer rechargeable battery pack for the best rate of 1C, which means a 1000 mAh battery packs should 1000mA current fast charge to charge such a rate can be achieved the shortest charge time, and will not reduce the battery performance and shorten the life. For the ever-increasing capacity of the battery group, want to achieve this satisfactory charging rates,Sony laptop battery increase charge current value is inevitable.

Lithium-ion battery nominal voltage 3.7V (or 3.6V), charging cut-off voltage 4.2V (or 4.1V, the batteries under the brands have a different design). How to distinguish battery is 4.1V or 4.2V: consumers do not distinguish between, it depends on batteries manufacturers product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is basically 4.2V. The 4.1V to 4.2V rechargeable batteries for what will happen: will increase battery capacity, feels good to use, standby time increases, but will shorten the battery life. For example the original 500, reduced to 300. Similarly, the 4.2V of the overcharge batteries, it will lower its short-lived. Lithium-ion batteries is very delicate. Since the battery inside a protective plate, we can rest assured it: No, because the shield is the cut-off parameter 4.35V (this is good, the bad to 4.4 to 4.5V), protection board is to meet in case, if the per times are too rechargeable, the battery will soon decay.

Therefore, the charge is usually eight hours, excessive time is also to no avail.

How do I charge the battery for a new

The use of lithium batteries should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3--5 times the normal charge-discharge cycles the battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect. Mobile phones so users of the new lithium battery in the activation process does not require special methods and equipment. Not only the theory that, from my own practice point of view, from the outset, a standard method of charging such"Natural activation"Approach is the best.

For the lithium battery"Activation"The problem, many say is: recharge time must be more than12Hours, repeated three times to do in order to activate the battery. Such"The first three charge should be sufficient12Hours"The argument is obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument., Sony PCGA-BP2NY Battery, Sony PCGA-BP2R Battery, Therefore, Sony PCGA-BP2NY Battery, this argument can be said that a beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid ion battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, is not to carry out more than12Long charging hours. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.

Lithium battery cell phone or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for the so-called continuous10Hours of"Trickle"Charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of fail-safe, so your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.

In addition, in some mobile phones, charging more than a certain time, if they do not remove the charger, this time not only to stop charging system will start to discharge--Charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone/Charger is detrimental in terms of life expectancy. At the same time, long charging would take a long time, often at night, but to our power grid situation, at night in many places higher than the voltage, but also volatile. As already said, the lithium batteries is very precious, and it more than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.

In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following questions.

Li-ion battery cell phone right way:

I lithium batteries used in mobile phone charging and discharging, the most important tips are:

1, in accordance with standards and procedures, charging time, even the first three have to do so;

2, When the phone prompts when electricity is too low, we should try to begin charging a timely manner;

3, lithium batteries do not need to activate the special method, Sony PCGA-BP2R Battery, in a normal cell phone use lithium batteries will naturally activated. If you insist on spreading the use of "the three previous12Hour long activation charge "approach, in fact there will be no effect.

Therefore, all the pursuit of12Long hours Li-ion battery charging and to mobile phones used in the practice of automatic shutdown, , Sony PCGA-BP2NY Battery, Sony PCGA-BP2R Battery, are wrong. If you have previously done in accordance with the wrong argument, please correct in time, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control circuit of good quality cases, the protection of lithium batteries is still quite guaranteed. Therefore, the charge is the focus of understanding of the rules, and in some cases also may make some concessions. For example you find in your cell phone the night before bed charge, you can also start charging before going to bed. Crux of the problem, you should know what the right thing, and do not deliberately wrong to do so in accordance with.

Rechargeable lithium batteries with the knowledge of mobile phone

Principles of integrated presentation of mobile phone charger

All mobile phone charger actually made up of a stable power supply (mainly regulated power supply,laptop battery to provide a stable operating voltage and sufficient current) with the necessary constant, pressure limited, time-bound and other control circuit.

Original charger (referring to the line charge) on the labeling of the output parameter: for example, the output 4. 4V/1A, the output 5.9V/400mA ... ... refers to the internal power supply of the relevant parameters. To understand this truth, you are know a (good quality) mobile phone charger is easy to change a good quality of the regulated power supply! For example output 4.4V to 4.5V device can be used, 5.9V to 6V of equipment that can be used ... ...

Mobile commonly used lithium-ion (lion) battery charger uses a constant current charging system voltage limit, charge current is generally used around ---- C2 which adopts a two-hour charge rate, for example 500mah rechargeable battery using 250ma about two hours up to 4. 2V and then constant voltage charging.

lion batteries are not suitable for use NIMH battery charger used for high-level rapid detection of fast-charging -DV/DT, because lion battery charge current, there are strict limitations. lithium-ion (Li +) is very lively, high-current charge is easy to be dangerous.

Have access to the domestic famous lion-ion batteries manufacturer's technical staff, based on their destructive experimental report: The normal circumstances lion battery (batteries) in the discharge (including the short-circuit) are generally not an explosion,Sony laptop battery
Sony PCGA-BP1N Battery, Sony PCGA-BP2NX Battery, but the likely to be overheating and burning, but the more serious charge over-current situation is very prone to explode!

Currently appearing on the market can be for a nominal 250mah --- 2500mah battery "universal cell phone charger," in fact is very dangerous, and its lack of battery capacity testing, using a fixed output current for different batteries, the not the cause of charging time is too long lead to over-current charge, Sony laptop battery it is recommended you do not have as wonderful!

Now USB mobile phone charger, only do not use a computer USB port are available in a relatively stable power supply from the computer 5. 0v voltage as the charging voltage source, and then also backed up by relevant circuit and pose a USB mobile phone charger, the output Quality In addition to USB port maximum output current is subject to, the key is determined by charging circuit of the design and materials, the pros and cons of the. Therefore, we want to buy design a more reasonable, reputable brand-name maker of the product.

How do I charge the battery in use for a new lithium batteries should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycles the battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect.

Mobile phones so users of the new lithium battery in the activation process does not require special methods and equipment. Not only the theory that, from my own practice point of view, from the outset on the use of standard method of charging that "activation" approach is the best.

For the lithium battery "activate" problem, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery. This "The first three charging more than 12 hours to charge" was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid ion battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.

In addition, lithium batteries cell phone or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. Sony PCGA-BP1N Battery,And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of fail-safe, so your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.

In addition, in some mobile phones, charging more than a certain time, if they do not remove the charger, this time not only to stop charging system will start to discharge - charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone / charger is detrimental in terms of life expectancy.

As already said, the lithium batteries is very precious, and it more than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.

In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge,Sony laptop battery
Sony PCGA-BP1N Battery, Sony PCGA-BP2NX Battery, over-discharge of lithium batteries is also very unfavorable. This leads to the following questions.

2, normal use should be when to start charging

In our forums, often see this argument, because the number of charging and discharging is limited, so phone the battery should be used up as much as possible recharge. But I found one on the lithium-ion battery charge and discharge cycle test table, on the cycle life data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal case, you should have a reserve battery power is left in accordance with the principle of charging run out of charge again, but if your battery in your first two days can not be expected to persist throughout the day, when they should start on time charge, of course, if you are willing to back the charger to the office again a different matter.

And you need to recharge in order to cope with the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery power over time, then you just charge ahead, because you are not really lost, "a" sub-charge cycle life , that is, Sony PCGA-BP2NX Battery, "0.x" times only, and often this x will be very small. Run out of battery power and then filling the remainder of the principle is not want you to go to the extreme. And long, like charging a widespread view that "as far as possible the cell phone battery power used up,

Best to use automatic shutdown. "This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears still do not charge to continue to use the example has been used in automatic shutdown. the results of this case, cell phone charging and starting later in the no response, had to give customer service overhaul. this is in fact a result of the excessive discharge as a result of the battery voltage is too low , so that does not have the normal charge and the boot and conditions.

3, for lithium batteries cell phones right way

To sum up, I lithium batteries used in mobile phone charging and discharging, the most important tips are:

1, in accordance with standards and procedures, charging time, even the first three have to do so;

2, When the phone prompts when electricity is too low, we should try to begin charging a timely manner;

3, lithium batteries do not need to activate the special method, Sony laptop battery
Sony PCGA-BP1N Battery, Sony PCGA-BP2NX Battery,in a normal cell phone use lithium batteries will naturally activated. If you insist on spreading the use of "the three previous 12-hour long activation charge" approach, in fact there will be no effect.

Therefore, all the pursuit of super-long 12-hour rechargeable lithium battery cell phone use and the integration of the practice of automatic shutdown, are wrong. If you have previously done in accordance with the wrong argument, please correct in time, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control circuit of good quality cases, the protection of lithium batteries is still quite guaranteed. Therefore, the charge is the focus of understanding of the rules, and in some cases also may make some concessions. For example you find in your cell phone the night before bed charge, you can also start charging before going to bed. Crux of the problem, you should know what the right thing, and do not deliberately wrong to do so in accordance with.

In other words, a new generation of cells have not so much stress, and more convenient, casually when I wanted to charge to charge it, as long as no charge blasting machine like!
