Drawbacks and hidden laptop battery

“Battery door” incident occurred a few years ago, exposed the drawbacks and hidden in the laptop battery. Dell laptop spate of explosions in Japan and the United States is the most frightening. However, Apple, Asus, Lenovo, HP, and even Sony could not escape this doom. Consequences due to notebook users “talk battery color change”; Although the laptop manufacturers to ruin, but also lost the edge consumer; several airlines have for using a laptop on the aircraft also made the restriction measures. A moment on the occasion of the birth of the new laptop battery technology into thing hope people Date Night.

In fact, in addition to the laptop, the news of the explosion of portable electronic products often been published, fundamental research, are acer battery blame. Nevertheless, the evolution of technology traveled alone, the increasingly powerful laptop, in time, whether it can be as arms weapons treated.

Enter the Dragon of the apple laptop laptop market, increasingly fierce, forcing vendors who have sought to drive down the cost of the best way to improve efficiency. In this case, the the notebook battery there may Wanjiebubao the quiet low-key.

The laptop portable device behind weekdays scenery aspirated what not sink by the pain of it? Notebook performance with the processor upgrade their technology, but also a qualitative change, processor manufacturers claimed that the new processor in the control of energy consumption do well, but the frequency increase, is bound to generate more heat. If the battery for asus standard “no foot peg teeth” is very easily lead to the entire notebook disfigurement, serious point, disfigured more than a notebook.

For in-depth understanding of the compaq notebook battery, try the laptop battery website from Google search, many laptop explosion “reported a list during. Understand that some people want to make that Taiwan notebook makers and battery manufacturers disrepute computer the auction explosion notebook from the Yahoo website, like a hand grenade thrown into the parking lot, to arouse people’s safety awareness on the laptop battery. It seems that when the understanding of the structure and security of the battery problem.

Works on laptop battery, laptop battery structure is extremely simple. A housing, a working circuit, plus a battery pack. Wherein the circuit is the most important part, because of the use of the process of a battery itself, is recorded in the circuit board. General laptop battery batteries for 10.8V or 11.1V, laptop batteries are composed of multiple single cells in series and parallel battery pack. People often see the battery casing superscript 3300mAh, 4400mAh, such as identification, it is said that the capacity of the battery, indicating that the current one hour dell battery discharge, for example: 4400mAh lithium battery 4400mA current discharge hours. So, is proportional to the value of their work time.

Notebook battery works to prevent overcharging lithium battery in the charging process, when close to full voltage will decline slightly that full battery protection circuit will cut off the power control circuit detects this situation ; discharge when the battery voltage is basically stable, only little power left in the battery only when a sudden drop when the control circuit detects this situation, we think that the power of the fujitsu batteries are nearly empty, and notify the protection circuit cut off the power to prevent the battery life is shortened due to excessive discharge. Considerations from the security point of view, when the control and protection circuits work diminished capacity, then, on the brink of danger.

Second, the hp laptop battery replacement technology along with the rapid development of technology in laptops and fine small electronic products, electronic products battery stability, the use of time, volume and even the number of charge cycles, charging time are proposed more stringent requirements. To reduce the volume reached at the same time extend the use of time, increasing the frequency of use, and reduce the memory effect of the negative impact such purposes, taking into account the cost of the battery and the use of security, battery selection constantly refined. Cathode material for lithium-ion battery, for example, can be broken down to the lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and other raw materials. Currently, two chemical ingredients most commonly used in the battery, nickel-metal hydride (NiMH: Nickel Metal Hydride) and lithium-ion (Li-ion).

Third, the maintenance and use of the use of the batteries for lenovo, the lithium battery will make people feel squeamish, they are too sensitive to hot and cold. And can not meet the fast amp fast charge to charge and discharge, and if the power is put to the spotless, will pose a threat to their life. Comparing the two under the nickel-metal hydride battery is much more secure. But if you put a few months, it will power put a drop is not left, after repeatedly charging is needed before they can recover 100% of the charge capacity.

Avoid reducing battery life: Do high-temperature use of laptop at least provided with a fan will help dissipate the heat generated by the internal hardware of the fuselage. However, due to the mold design problem, most of the heat will be blown directly onto the battery. For ibm lithium batteries, which seems directly heating the battery, make the battery life is at stake. , In order to avoid a sudden power failure causing distress, while the battery is installed in the notebook, his home life is tantamount to strangle the life of the laptop battery.

Avoid reducing battery life: Do not fast charge a new generation of notebook the popular battery fast charging, fast charging battery is easy to let heat, resulting in chemical composition within the battery into the gas gets lost, the sony laptop battery will too fast damage, damage to the battery is also due to the rapid charge-discharge and accelerated deterioration. If the design of a gas controller to reduce the charging rate, perhaps it will be much better.

Fourth, this perspective on notebook nickel-metal hydride battery and notebook lithium battery 9.6 Volt 3000mAh Ni-MH battery specifications, nickel-metal hydride battery technology is a very safe design, there is no need to protect the auxiliary lines, wiring completed on the upper edge of the stencil sheet, to avoid batteries for toshiba pack caused by accidental short circuit.

Notebook battery will be the development of what? The development of the fuel cell will make people look forward to again. This technology is the use of energy liquid or gelatinous substance, like the practice of gasoline into the vehicle tank. Nowadays found that alcohol or hydrocarbon liquid, there can be a high energy density performance. The future notebook battery will be how to develop, we will wait and see.

Question:””Your battery is temporarily disabled. Please turn off your computer and try again when the unit is back to the operational temperature””

Answer:”If removing and reconnecting the battery did not help,try updating the BIOS on your system using this link below :

http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/xps-15z?driverId=2M3N1&osCode=W764&fileId=2731104281

Note:While updating BIOS the replacement dell AC adapter should be plugged in and battery should have more than 10 % charge.Also disconnect all external peripherals (such as USB devices) from the system.

If the issue persists even after updating BIOS and if the system works fine,without shutting down only with the AC adapter connected(without the battery),than you will need to get the xps 15z battery replaced.System battery comes with one year of warranty.”
in addition,pls Pay attention to Dell XPS 15Z battery maintenance:

Dell XPS 15Z battery life not by the length of the total use of time, but by the charge and discharge times to decide. This dell 15z notebook is the importance of maintenance. If you always to the laptop without the battery installed to take down, even if the machine off and remove the AC power after the battery is not like the thought kept as fully charged state. because the Dell XPS 14Z battery in the integrated control circuit, so even when the power is also turned off the computer power. As one connected to AC power, the battery will start charging, when on or off, your Dell laptop battery is repeatedly charged and discharged will affect dell 1525 battery life.

Therefore, when using the AC external power supply is best to unplug the xps 15z battery, laptop battery for a long time in the heat or the state of their life affected. To maintain the battery for the long term do not, charge and discharge at least once a month to ensure that its activity. In the custody of the battery when there is a need for attention.Currently, the vast majority of laptop lithium-ion batteries used in a long time if not used, often prone to over-ischarge phenomena, may no longer be able to charge laptop batteries. In order to prevent over-discharge, charge state in half to save it in a cool dry place, and then every six months, then half of its electricity to the state of charge.

Power adapter manufacturers need to embrace the new trend

Not long ago, the laptop is limited, such as the power requirement of only 50-70 watts (W). In recent years, power requirements, climbed to more than 100 W range, but the weight and size of the desired no corresponding improvement. In addition, the need to meet the low standby power adapter performance specifications, the harmonic efficiency requirements of the external power supply (EPS) and IEC1000-3-2 for more than 75 W of input power requirements make this challenge even more difficult to deal with. This article explores the recent trend of acer power supply manufacturers can address these challenges, and provide a different alternative solutions to choose from.

With laptops increasingly feature-rich electronic power requirements increase. In addition, because of the increased laptop battery capacity (or density), the charging requirements also increased – so, laptop power adapter for greater doubled. However, for millions around the world carry the laptop user, the larger and / or more thermal power adapter is not too attractive alternative. Can be attractive apple laptop adapter has a lightweight and small, but immediately charged. Of course, it does not produce heat, but does not spend too much. In recent years, the development of electronic products did not increase our hope in this regard, and whether the future of the revolution can be achieved is still an open question. We also want a asus notebook adapter can be used globally, without the need for a 110/220 volt operating voltage selector switch – laptop adapter must be truly universal line voltage work. At the same time, the expectations of regulators and OEM also play a role.

Regulatory agencies notebook adapter for compaq does not waste energy or electricity lines harmonics. The first factor is that the adapter does not insert the plug with no load, it should be as little as possible the absorption of the power (standby requirements). People generally used the laptop adapter for delta is plugged in, but not connected to the computer, the requirements can prevent the loss of this case. The second factor is the recent requirement, it requires specific average power efficiency under different load conditions (25%, 50%, 75% and 100%) by the global specification bodies perform, in order to promote compliance with the specification and reduce overhead costs. Finally, reduce the harmonic requirements enforced by the European Union and Japan have been used in dell laptop power adapter, because they have already exceeded these standards 75 W input power threshold. In a sense, the movement of the laptop adapter / Universal features making it the first mass production of power products IEC1000-3-2 specification.

Existing solutions and existing laptop converter general flyback topology, the pulse width modulation (PWM) converters. It was for many years the most effective solution (in terms of cost and technical). As shown in Figure 1, a typical flyback converter for laptop adapter for fujitsu at universal input voltage range (90-265 V ac), and ON Semiconductor has introduced a highly integrated PWM controller solution , the use of fewer components. If less than 75 W, the power level of the adapter without additional power section. The key performance criteria for these adapters is the power density (package size requirements), safety and low case temperature. The main method of control is to achieve classic UC384x series current mode control. However, as shown in Figure 1, the laptop hp ac adapter with different PWM controller (such as ON Semiconductor, the NCP1200). The new generation PWM controller is better than UC384x is:

The higher level of integration to reduce the number of external components, while still retaining the advantages of current mode control; * be able to enter skip mode to reduce standby and light load losses; * start input high voltage (HV), reduce the start-up circuit loss and component costs; without IC error amplifier circuit, error handling to be completed in the secondary; * easy to comply with safety and EMI, in order to market faster.

However, for more than 75 W power requirements of the hp compaq power adapter, the laptop manufacturers face a choice. Join the power factor correction (PFC) for universal application design adapter and need PFC (Europe and Japan) market segment or separate design. The increased PFC stage to increase the complexity and cost, make the design more challenging. Typical design applications in this application as shown in Figure 2 critical conduction mode (CRM) boost PFC stage.

CRM PFC design uses the MC33262 controller, as shown in Figure 2. This simple 8-pin controller can easily achieve liteon laptop power factor correction. In critical conduction mode, you can achieve some circuit level advantages, such as non-the diode recovery issues and lower switching losses.

Although manufacturers to adopt this approach has been embodied in the existing design performance and cost acceptable, but still need to be improved in order to meet growing emerging requirements.

In the PFC, although the main CRM methods, but there are obvious limitations. First, it is a variable switching frequency mode work in the zero crossing and under light load conditions, and the switching frequency may be increased to high. Variable frequency filter and low standby laptop power for ibm consumption problem. The NCP1601 introduced a new solution, it draws on the best features of the method of the critical mode, while limiting the switching frequency and improved standby performance. In this solution, the controller can seamlessly in discontinuous conduction mode (DCM) and critical conduction mode switch, and will not affect the sony ac adapter factor correction. The line voltage is at or near the zero-crossing and under lighter load conditions, the controller to work real fixed-frequency DCM PFC mode. Full load and near the peak of the waveform of the line, the controller switches to the critical mode, thus limiting the peak current value does not become too high.

In addition, in recent years, PFC implementation available discrete components come a long way. PFC MOSFET requires a rating of 500 volts, and the introduction of low Rds-on and a small gate charge MOSFET have a tremendous help. CRM or DCM boost diode circuit and manufacturers have begun to introduce a variety of components, such as MUR450PF, to cater to these needs require different characteristics.

The final result of these improvements is increased PFC adapter for toshiba design from a cost point of view, not a big burden, while at full load, low line efficiency of about 95% efficiency and <300 mW standby power consumption. These performance obviously adapter designed to meet OEM specification requirements.

Laptop Battery Maintenance has always been easy to overlook one of the faithful, there is also a lot of misunderstanding, just friends and relatives to buy a Dell brand laptop today, asked about Asus G75 Battery maintenance should pay attention to what, and how to maintain Asus G74 battery own knowledge and practice to master, I here for everyone to be described in detail, we want to help.
From the birth of the laptops that day, the debate on the Asus A42-G74 Battery has never stopped, and thus the notebook laptop battery Persistent become a very important one of the technical indicators. So in the end how to use in order to maximize the effectiveness of the Asus Eee PC 1005HA Battery to extend battery life? Here the author to introduce some of the basic methods, notebook batteries using lithium-ion battery, the following maintenance are around the type of battery maintenance.
Laptop Battery Maintenance: activate the Asus G73JH Battery, a battery good beginning
Many laptop are activated, which means that the new notebook battery first boot with 3% of the electricity consumption (which is also the manufacturer’s instructions will generally described) At this point, you should not use an external power supply , the Asus F50 Battery inside the power exhausted, until the shutdown, and then use the external power supply charge. Home, but also the exhaustion of the battery after the charge, charging time must be more than 12 hours, repeated three times, in order to activate the Dell Vostro 3500 battery, so as to lay a good foundation for future use.
Laptop Battery Maintenance: to minimize the number of battery
We all know that the Dell Inspiron 1470 battery charge and discharge is directly related to the life of one charge and put a battery, the Dell Latitude E5420 battery will consume a small part of life, we should all know this principle, for example, can buy a new mobile phone is fully charged to begin a long time, but after a time will find the time obviously did not begin so long, is the same reason, we recommend that you try to plug in an external power supply, do not go using battery power when external power, in order to avoid affect the Dell Mini 1010 batterylife.

Insist on the right to use, effective way to extend the Lenovo b465 battery life of notebook. Users can reduce machine power consumption by adjusting the screen and graphics mode to increase the Lenovo ideapad y580 battery life of the notebook. Secondly, not to use the laptop, you can set the computer into standby.
In addition, the external device will increase the machine power, mouse, U disk, memory cards and other external devices unplug and turn off the wireless card, an infrared port and Bluetooth, and even reduce the operating frequency of the processor. These are the necessary means to extend the Asus a42-g75 battery life under certain conditions.
In everyday use, pay attention to the the notebook body temperature, try not to be used in a low temperature environment. At the same time, we must pay attention to the body heat, it is recommended through the cooling pads way notebook timely cooling, so that not only can extend battery life, and the life of the other components of the notebook is also good.
Asus a42-g74 laptop battery life by a battery charge and discharge times determining the charging and discharging operations, will accelerate the aging of the battery.
Became to extend the Asus g75 laptop battery life of the key elements of how to properly charge and discharge.
Most laptop battery fully charged, the battery charging circuit is still in an open state, therefore, it is recommended that in the case of external energy to try not to use the battery, not in the external power supply with Asus g74 laptop battery case repeatedly plug, because in the case of ample power, each plug an external HP Pavilion HDX9000 Power Adapter, the equivalent of a single charge, the laptop battery is the same as in the aging of the road a step forward.
Removing the battery from the laptop have to abide by certain rules of preservation, the more serious consequences of lithium-ion battery deep discharge, may cause serious battery failure or a total loss, so the Asus f50 battery storage about three months after, recommended to remove the batteries recharged, had to do to avoid battery discharge.

BATTERY TIPS

Attention when use your new ASUS G75VW battery pack

How to prolong Asus G75VW laptop battery life ?

Don’t mix old and new Asus G75VW batteries when you use them. The new ones will be stronger and can cause the older ones to leak battery acid.

Cut down external devices – USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use.

Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down Asus G75VW battery life.

Prevent the Memory Effect – If you’re using a very old laptop, you¡¯ll want to prevent the ‘memory effect’ ¨C Keep the Asus G75VW battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.

Avoid use in outdoor or harsh environments, and to prevent the Lenovo b465 battery is exposure or moisture. When you do not use the Lenovo b465a battery when, Unplug. Long energized let adapter has been in working condition, will affect the ultimate service life. 3 adapters are all broadband working voltage marked from 100V-240V can, but if used in the case of very unstable voltage, it will also cause damage to the Lenovo b465c laptop battery

The adapter failure usually where? Under normal circumstances, the failure of the Lenovo b465g battery is more in line, like the interface at the wires and adapters to connect first class. Easily lead to a power cord because these parts are often bent, broken, or poor contact. Such failure may be renovated, a new line opens for root on OK. The Dell Latitude E6420 AC Adapter now on the market, in fact many are changed his line or renovated, will not affect the result of the restoration of normal use.

How to make a power adapter longevity?

A long time due to the Lenovo ideapad y480 battery does not belong to the vulnerable parts, if the method can be used properly. Below is necessary to say a few precautions:

Adapter are generally marked “restricted to indoor and information products, so you should try to avoid use in outdoor or harsh environments, prevent Dell XPS M1730 AC Adapter exposure or damp. Not only adapter that many electronic products should pay attention to these two points. Because exposure will accelerate the aging of wires, such as Shell, it makes use of the temperature rise. As for moisture, it may lead to an internal short circuit, causing burned.

Unplug when you do not use the Lenovo ideapad y480m battery. Long energized let adapter has been in working condition, affecting life. In addition, at the connection of the Lenovo ideapad y580 battery cord and adapter must be special care, the wire bending angle can not be too dead, so is likely to cause the wires to break. Junction of the adapter should also avoid bending, otherwise it will cause poor contact. The adapters are all broadband working voltage marked 100V — 240V, but if used in the case of unstable voltage, the same damage.

I believe that many users have the same feeling: after prolonged use of laptops, the hottest place than body surface, or even near the outlet, but the notebook power adapter next to pick it up, there is often the feeling of hot, indeed people worry that it will one day suddenly strike, or if there were howling, smoke and other faults. HP Pavilion dv4 AC Adapter is a high-precision, high-efficiency switching HP Pavilion DV7 AC Adapter, 220V AC electricity is converted to low voltage DC to provide stable power for notebook normal work, it can even be called a notebook. ” the source of power. ” Inside the Toshiba PA3715U-1ACA AC Adapter is a switching power supply work in the high-voltage, high-current state, the work load is heavy, and a fully enclosed structure, no cooling holes in the housing, internal fan assisted cooling, and thus Dell Alienware M11X R3 AC Adapter the internal temperature at work are very high. Especially in the hot summer, touching the surface can feel hot, the internal temperature is higher. Thus in the day-to-day office, entertainment, to it the proper care and maintenance.

Create a good thermal environment. Using a laptop in a high temperature environment, should be placed in the Dell Latitude E6320 AC Adapter and airy place away from direct sunlight; near the cooling air outlet Dell Alienware M15x AC Adapter on the laptop, otherwise not only the power adapter The heat does not go out, but also to absorb part of the heat. In the hot summer, we can put the Dell XPS M1730 AC Adapter side, in order to increase the contact area of ??the adapter with air, so that the adapter’s better dissipate heat. In order to obtain a better cooling effect, we can also pad between the adapter and the desktop into a narrow plastic block or piece of metal in order to increase the air convection speed of the adapter around, to speed up the adapter’s heat. The exception occurs shall promptly stop using. Asus ADP-90SB AC Adapter to issue a large noise even smoke, often damaged or malfunction, you should immediately stop using reconditioned by the professional engineer before put into use again. The use of non-original power to be careful. Non-original Asus ADP-150NB D AC Adapter output interface, voltage and current values ??there may be some differences (or nominal and actual discrepancies), if the mismatch, it may affect the stability of the notebook running even more serious consequences . In addition, the different models of the same brand notebook Asus EXA0904YH AC Adapter switching to should be careful, we detail later.
