So far, the industry agreed that the lithium-ion batteries for electric cars is still the main way of energy reserves, but now have several companies began to consider using a super capacitor (ultracapacitor) lithium-ion battery products as a good additional equipment.

South Korea will be an electronics company Neescap Tuesday claimed that 9 million U.S. dollars will be invested to expand its transportation, electric power systems and consumer electronics products with super capacitor (ultracapacitor) the product capacity. In the United States and ability to design and manufacture of super-capacitor products and electrolyte materials needed for the company There GrapheneEnergy, EnerG2 and Ioxus 3. Another one EEStor companies by VCs KleinerPerkinsCaufield & Byers as the background, now the company has signed an electric car company Zenn super-capacitor supply agreement.

The more traditional batteries, super capacitors can store the electricity are not many. So at home Rechargeable (Plug-in) electric vehicles, such a capacitor can not serve as power supply equipment alone, but need to tie in with the fuel cell use. On the other hand, the super capacitor is also equipped with fast-diarrhea release energy stored in the ability. In addition, the capacitor charging time is very short, only takes a few seconds or minutes of time will be able to complete the charge, but charge several times the performance of there will not be reduced.

Capacitor current consumer electronics products have been used in digital cameras and other occasions, in order to flash this need momentary high-energy input of the device provides energy supply. According to experts, super capacitor the key issues facing the future is how to increase the kinds of capacitor voltage so that it can in the high-voltage environment.

According to Ioxus engineers said, the super capacitor is environmentally friendly energy, a good supplement can make batteries, fuel cells, solar or wind power generation, power supply would be more perfect. At the same time capacitor used in the production of such materials are also very environmentally friendly, the price Some are more readily accepted.

Super capacitor technology, the future development direction:

Massachusetts Institute of Technology computer electronic engineers JoelSchindall said that in the next few years, the super capacitor energy storage capacity will be a qualitative leap forward. The current super capacitor product discharge rate is 10 times that of traditional batteries, while the energy storage capacity in the volume of the same only the latter under the condition of 5%.

He said: “super-capacitor charge and discharge operations of certain frequent use of a great occasion, such as Brake Energy Recovery-type brake system (that is, five sets of F1 shows on CCAV all day nagging what Coles host system), This capacitance is very easy to use. Of course, this product is currently not yet a large scale to replace the batteries. ”

Over the past five years, Schindall led research team has been studying the super capacitor in the energy storage component – porous carbon material, replaced with another carbon nanotube conductive matrix material + energy storage components. Earlier this year they have been established to the FastCap companies, in order to the commercialization of research results.

Schindall said the super capacitor energy storage capacity of the product will eventually reach about 25% of the SONY VGP-BPS2 Battery. Massachusetts Institute of Technology developed at present out of nano-materials, energy storage capacity has reached twice the level of carbon materials. But the next few months, he led research team will be showing the kind of energy storage capacity is five times more activated carbon products.

Planting the seeds of electrolyte “missile”

According to the U.S. well-known science writer series of articles in the lithium batteries in the introduction, the vast majority of lithium battery explosion caused by a short circuit, and the specific reasons, including charging overvoltage / over-current use of aging.

Lithium battery manufacturing process, because the manufacturing process itself flawed, it is easy to be insulated in this between the two poles, leaving metal dust, copper foil, aluminum foil pieces. The angle is expected in the battery than the fever (more common in long-term use or charging), the like boiling water in a grain of rice, as in the electrolyte to make random thermal motion. If you happen to have the APPLE 15-INCH ALUMINUM POWERBOOK G4 SERIES Battery positive and negative particles or debris near the middle of the diaphragm level, it could create a divide perforation, triggering micro-short circuit. As the batteries are flammable organic electrolytes, micro-short-circuit may cause an explosion, burning and other accidents, generally have the following three cases:

1. Sparks ignited the electrolyte, and thus bring disaster to come into contact with plastic body and flammable, resulting in fire;

2. Was experiencing an increase of temperature caused by the battery, the battery inside the space is small, perhaps because of increased pressure to explode;

3. Batteries slower rise in temperature, the battery case to melt gradually, so that corrosive electrolyte leakage.

Lithium battery safety problems can not stop now, because then the advanced manufacturing technology, will inevitably lead to planting the seeds in the electrolyte “missile.” Should be noted that the formal sector of lithium battery production and sales have strict norms of acceptable quality lithium batteries, the number and size of debris have been controlled within a very small, very low risk of perforation of diaphragm; Battery Case also used flame-retardant material, is not prone to fire.

The explosion-proof lithium battery of measures

Lithium battery safety problems, the battery manufacturer, of course well aware, then what they used explosion-proof measures? Li-ion batteries for notebook computers, for example, its working principle is: Lithium batteries near full charge and discharge almost drained when the voltage drop, the control circuit detects this situation, notify the protection circuit cut off power supply to prevent overcharge or excessive discharge, so as not to shorten battery life.

The current notebook lithium batteries possess a more complete multi-level protection mechanism, even in the power charger, notebook computers unusual circumstances, the laptop battery can also be converted to automatic protection status, is generally not an explosion. But once the control circuit and protection circuit of the ability to work reduced hours, the battery on the verge of “dangerous” the. Mobile phones and other electronic products, lithium battery charge and discharge protection mechanisms, similar to this.

Do not need it “at arm’s length”

In recent years, lithium-ion electronic products explosions often found newspapers, aroused a lot of consumer panic, some people for their own mobile phones, MP3 charging often “at arm’s length”; also because of fear, simply a long-term will be cast aside laptop battery, cause scrap. However, survey results, the majority of lithium battery explosions are the result of the user pay attention to safety tips, such as unauthorized modification, use of non-matching charger, the battery placed in extreme environments such as making.

Should be pointed out that the lithium battery technology as a kind of after 30 years of study, has successfully commercialized the mature technology, its safety is guaranteed. Regular brands of lithium batteries at the factory will have been numerous Road test procedure after they are sold as well as information feedback mechanism in order to recall the product in question in time.

United States Transportation Security Administration (TSA) is given following the recommendations of the safe use of lithium batteries:

1. Using the original charger: Li-ion battery charging time is the high period of bombing. Than the original battery charger is compatible with the battery charger to ensure better security.

2. Use of a reliable battery: try to buy original batteries, not to save money to buy “second-hand goods”, such batteries may be through maintenance, and reliable than original batteries.

3. Do not place the TOSHIBA SATELLITE A105 SERIES Battery extreme environments: high temperature, collisions, etc. are all important causes of battery explosion, as far as possible so that the battery is in a stable environment, away from the high-temperature areas.

4. Do not try to modification: Many young people like their phones to “cosmetic”, but it was “bold but cautious” manner to transform mobile phone on their own. However, it can easily lead to improper modification accident. Mobile phone is a sophisticated communications equipment, in the design, manufacturers will have on its security, strictly textual research. After modification, the battery may be at not taking into account the environment before, an increase of security risks.

Use rechargeable batteries

Use rechargeable batteries for notebook computers, one of the relative advantages of the desktop, it can greatly facilitate a variety of environments the use of notebook computers. Introduced the first battery is nickel-cadmium batteries (NiCd), but this HP F4098A Battery has a “memory effect”, each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH not only failed to “memory effect”, but can make more per unit weight of 10% of the electricity. The most commonly used battery is lithium-ion battery (Li-Ion), it is also no “memory effect”, as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds battery is 1:1.2:1.9 ratio.

Notebook computer batteries currently used in three kinds of main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.

The purchase or replace the battery when the laptop for many users, the “batteries” may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, height of about 7,8 cm, voltage is 3.6v of small units. They are the batteries, just like a small battery, through the series combination, that is, we see the battery has. Then talk about how to determine if the battery is several cores:

One way: Disconnect the battery to the number of contacts to see him, there are a few of the tens of cores. But this is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such as 14.4v, and then divided by 3.6 to be 4, then proved to be four batteries together in series. And then take a look at the capacity of the battery block, for example 3800mAh, then prove that the above mentioned two sets of batteries in series, because the small battery capacity is 1500-2000mAh, even more, to be two to reach 3800mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.

The composition of laptop battery

Laptop battery from shell, circuit boards and batteries, belonging to lithium-ion battery. People are talking about batteries in general refers to the number of batteries within the battery, mAh refers to the laptop battery capacity.

Mainly by the protection circuit board (or the secondary protection circuit), and the capacity of directed circuits of two parts, notebook battery charge and discharge and safety management.

Laptop battery standby time mainly by the mAh value to decide. Under normal circumstances, a few more batteries, mAh value is greater the longer standby time. Laptop battery life mainly by the charge and discharge times to measure the quality of the products are generally eligible for 500-600 times. Therefore, the effective use of laptop batteries within a period of two years, expired the battery will be aging, standby time affect the sharp decline in the mobility of notebook computers.

Laptop battery tips

In fact, how to make good use of laptop batteries battery, how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of notebook users, a problem, the use of laptop batteries There are many methods and techniques, which requires us to usually use more learning and application.

(A) rapid access to hibernation

Temporary non-use of laptop computers, in order to conserve battery power, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state?

Notebook computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make notebook computers into sleep mode immediately and effectively conserve battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.

(B) the screen-saving mode

TFT screen is the largest notebook computer power components, in order to reduce its use of the battery when the power consumption, notebook manufacturers have devised ingenious schemes, but in general are based on the lower screen brightness, and even turn off the IBM THINKPAD T42 SERIES Battery.

In some notebook computer’s power management settings you can customize the brightness of the screen, most of notebook computers by a specific shortcut keys adjust screen brightness, generally 6 to 8-level brightness adjustment.

(C) energy-saving settings

Desktop machines using alternating current, most people may not be the computer attached great importance to energy-saving features, but need to use battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the computer the effective use of energy-saving option.

Energy-saving settings require the user to adjust two: First, the computer’s BIOS setup program on the energy-saving mode in the settings; most important thing is there are many energy-saving in the operating system settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the CMOS settings.

1. BIOS in the energy-saving settings

In the CMOS settings, most had a “Power Savings”, which can choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the default power saving mode setting. Notebook computer power saving mode in several states, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Notebook computers, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. If the wait state, turn off the screen and hard drive; into hibernation, apart from a close monitor and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down, once activated, or restart the computer, desktop will be accurately restored to pre-hibernation state. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode to Standby Timeout time, set to enter Suspend Mode from Standby Mode to Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.

2. Windows in the energy-saving settings

For the average user, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the “management of hardware and software” entries, there are two notebook computers with energy-saving elements relating to: “Managing energy consumption” and “use of portable machine” in the “management laptop on the power.” Energy-saving settings during Windows, should read the contents.

In the Windows “Control Panel”, click “power management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” is set to “Portable / Laptop” and reasonable arrangement “system waiting for”, “close the Monitors”, “Turn off hard disks” and other options for . Different computer can control the option to have some differences, the new factory and the latest computer software will be more workable options, detailed settings should be based on the computer’s own features and Windows Help files to carry out.

In addition, if your laptop built-in infrared port, not the time to ban it, it can be extended laptop battery life.

(D) alarm settings

Set battery alarm in time to give prompt the user to save the information. Way is to click on Open “Control Panel”, double-click “Power” option, point “alarm” menu bar, “low-battery alarm” column, Windows 98 default is 10%, “a serious shortage of the battery alarm” column, Windows 98 default is 3% can make the appropriate modifications as needed. Click both the [alarm response] button, the “voice alert” and “displays the message” are selected, “the power level” may from time to select. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sounds to alert the user to save information on a timely manner. Finally click [OK] button to exit the power management settings.

(E) open the energy-saving function

In the “extended laptop battery life technology” section, we have introduced energy-saving feature is the use of a CPU technology, which allows the performance make notebook PCs to play with their ASUS EEE PC Battery life between the time to achieve the best balance.

Most new models of notebook computers both in the BIOS of the CPU energy-saving technology have given the support, by default is turned on, if not open as long as the enter the BIOS will support the option to open it OK.

(Vi) The use of third-party software to monitor battery status

In addition to Windows built-in power management features, there are many utilities available to monitor the battery condition. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is designed for notebook computer services software. In addition to the amount of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used.

PowerCenter total of three kinds of display.

(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the battery percentage and the remaining time available.

(2) CompactDisplay: in use is always at the top of the window display.

(3) MinimizeDisplay: make PowerCenter reduced to the Windows task bar, display the information is relatively simple.

PowerCenter is also attached to a control center, can be made up to six kinds of warning. When the battery – down to a certain level, a timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.

(G) intentionally run out of battery

Run out of Dell INSPIRON 6000 Battery on a regular basis in order to ensure a full charge. If you need to completely run out of battery power in the specific practice is: In the Power Management dialog box, select Battery Drain this particular power mode, all of its 3 Running on Batteries options are set to Never, this notebook computer on the will continue to run. Select the mode, and then enter the Alarms tab to lift the Low Battery and Critical Battery Warning check box is a check mark (so, when the battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run a number of computational complexity of the 3D demo program, so soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug.

A few months ago, Hewlett-Packard’s third-quarter results, HP Personal Systems Group third-quarter revenue of 8.4 billion U.S. dollars, down 18% year on year, in which revenue fell 10 percent laptop, desktop revenue fell 26%. Although HP is still occupying the top spot in the global computer industry, location, but the face of the corporate sector adjustment stimulate competition among peers, as well as worldwide, repeatedly broke the product quality problems, particularly China, the quality of the notebook market, frequent problems, Hewlett-Packard to maintain its current position, not always been easy.

Global personal computer market’s crowded

With the global economic recovery, the computer market began to pick up. Recently, the market research report published by IDC, global PC shipments top five computer manufacturers, in addition to Dell last quarter, a decline, other four showed a COMPAQ PRESARIO 2100 Battery to increase.

Last week, Lenovo’s new one-quarter earnings freshly baked. Financial report not only shows that Lenovo began to turn around, and the global personal computer shipments increased by 17% year on year, which made Liu was “very satisfied.” Lenovo’s strong rebound in business, mainly due to China and other emerging markets for the contribution of group sales, particularly in its stronghold of Lenovo’s sales in China rose 28 percent, sales increased 9%, with the words Lenovo CEO Yang Yuanqing “China once again played a ‘mainstay’ role.”

Also last week, some media reported that worldwide PC market share rose to second place just Acer chairman JT Wang said Acer’s notebook shipments this year will be more than 30 million, and next year will exceed 4000 10000. This figure, so that Acer is expected to go beyond HP, and become the world’s largest notebook maker.

Hewlett-Packard in this fierce battle, the same active adjustment strategies. Hewlett-Packard Asia Pacific and Japan, regional president, said Xue Jinde, HP will strengthen the Chinese market, sales channels. The end of this year, China’s sales network covers cities from the current 700 to 2000.

Price war ignore the quality of service

As the market pick up, competition is increasingly fierce, some recent brand computers also frequently be exposed quality issues. October 27 to October 30, Acer, Sony, Asus were submitted to the State General Administration of Quality Supervision, Inspection notebook computers and related equipment on the recall report. Among them, Acer decided to recall the number of Chinese territory involving a total of 12266 units, three kinds of models of notebook computers; Sony decided to replace free of charge in mainland China a total of 1715 units of power adapter; ASUS decided to recall laptop batteries around 3630.

Some analysts have pointed out that, due to the highly competitive notebook market, manufacturers of products for the price of “dropping lower and lower,” product cost compression, causing the security problem is one of the reasons. Some manufacturers have admitted in recent years, the highly competitive notebook market, the profit margins of notebooks have become less dominant in the market in order to not only the product to keep pace, the price should have an advantage, to cheap, the cost have a certain control.

In fact, HP’s product quality issues, has long been China’s major media exposure. Started the previous two years, until last year’s outbreak of “snow-screen” event, and this year appeared one after another “splash screen” event, HP notebooks have become the main characters, but at the AQSIQ Web site, and did not see the relevant recall information. Can be said that the blind pursuit of product shipments and market share, lower prices, lower costs, ignoring the product quality and after-sales service will only lead to widespread dissatisfaction with Chinese consumers. In the People’s Network IT channel related investigations, more than 95% of Internet users expressed the impression that HP was “extremely disappointing”, while more than 99% of Internet users expressed a desire for Hewlett-Packard, “the issue in this recall.”

Qiao advantage of this legal gap or infuriating consumers

In the “AQSIQ Defective Product Management Center” web site, the most recent time in HP’s recall of defective products, information is in the last year’s June 2. That HP worldwide recall of about 203,000 notebooks buggy batteries, the number involved in China is about 15000. However, this time it is precisely the large-scale outbreak of “snow screen”, when, why HP only within the framework of the global recall of laptop batteries, while ignoring the local Chinese region’s “snow screen” problem?

According to “China Quality News” report, HP’s recall of batteries is in line with the U.S. Consumer Product Safety Commission’s requirements to implement. However, there are still no information on defective electronic product recall laws and regulations. Perhaps, this is giving some companies the opportunity to avoid legal risks, giving the company save a lot of expenses.

But this clever approach has angered consumers. In the Baidu search engine, enter “HP snow-screen” and “HP splash screen” keyword, the search results more than 40000 and 90000, respectively. Almost all the video sites, can find User upload their own shooting problems on the HP notebook video. Some of the video, HP notebook computers which displayed a variety of unusual phenomena, and still others are angry at the matter and notebooks to consumers shattered. Some TV stations also carried a report on this incident, interviews, many consumers Hewlett-Packard Co. and their agents are very disappointed with the attitude of indifference.

Quick profit or to lose the Chinese market Hewlett-Packard

Perhaps the market is eager to compete for the computer maker’s mentality. However, the ants of the hole, ACER ASPIRE 3000 Battery bursts thousands of miles. The brands are the sum of all intangible assets holographic concentrated, consumers will buy the brand as the computer, it is because of the brand’s trust. But if these brands can not control the quality of the computer business, will ultimately be abandoned by consumers, the brand no longer is the enterprise’s cash cow, but simply a sign of just worthless.

Hewlett-Packard and Lenovo, Acer, the two local computer makers in a competitive Chinese market, which already lacked natural advantages, if the product quality and service attitude ignores consumers, relying on “Little Smart” means to obtain results on the glory, it is Hewlett-Packard is difficult to imagine how the Chinese market, and even a foothold.

We have invited to the Cheng-yang Networks, Inc., for everyone to answer some of the purchasing process of laptop battery problems. Today, we again requested Cheng Yang Networks for us to answer some of the dell inspiron 6400 laptop battery will encounter in the course of the problem.

Notebook Battery Frequently Asked Questions

1. Q: Several hours after the first charge, the battery power is still only shows 30%, which is why? The how to do to achieve 100% full charge?

A: encountered this problem, you can refer to the correction described in Article III of your laptop battery in order to achieve optimal performance to operate. If still not satisfied, please contact your supplier request a replacement.

2. Q: How long new battery to drive the computer time?

A: The laptop battery run time is difficult to determine. The actual running time depends on the power requirements of devices, screen size, hard drives and other accessories are consumed by the extra power, greatly reducing its running time, the total battery run time also depends on the device design.

3. Q: The battery is not fully used up on the charge will reduce the life expectancy?

A: The battery is fully charged according to the number of life-expectancy calculation, lithium batteries are generally 300-400 times. Of course, you do not have to worry about the power of the battery connected to a single charge, the battery charge times in general only when the completion of a full charge and discharge will be increased once.

4. Q: The battery charge to a certain percentage or even 100% after the cut off AC power, the battery does not discharge, the computer immediately shut down, and why?

Answer: (1) depends on your working environment temperature is not too high, if the higher temperature region, prolonged use of the battery will happen protection, in order to prevent accidents, the computer starts proceedings on the termination of the computer work, and you can turn off your computer, you can take out the battery and re-put it back.

(2) computers in the charge when the charging circuit is the easiest hair growth problems, the other possibility is that your computer is in the charge in the process of a problem. Please check your computer. At this point you can find the original battery, to see whether the computer can work.

5. Q: My Dell laptop does not recognize the battery, and display the “batteries not compatible with this computer, insert the Dell battery” and other similar information, and the lights kept flashing, how is this going on?

Answer: This message indicates that the battery of compatibility is not good, when this failure occurs, please contact your provider request a replacement.

6. Q: When I put the battery inside the computer, the computer automatically shut down, leaving the battery out, then the computer can work properly, this is why?

A: This shows that the battery has been faulty. This is a very small, probably due to short-circuit protection of the battery interface area caused by technical failure. Encounter this failure, please contact your provider request a replacement battery.

7. Q: The new battery does not charge Why?

A: All laptop battery manufacturer in the ship, the laptop battery will charge 40-50 of electricity. In general we recommend charging a night (about 12 hours). The initial use of a new laptop battery should be rechargeable (depth charge, and then the depth of discharge), 3 to 5 times, so that optimal battery performance. (Note: the battery during charging and discharging process of a certain temperature is normal). It’s hard to charge a new battery adapter, because they never depth charge. If this happens, remove the battery and then re-inserted. Charge cycle should start again. The first charge the battery several times when this may happen. Do not worry, this is completely normal.

8. Q: My original battery nominal voltage is 14.4V or 10.8V, and the constant surplus sold pute the corresponding models of the battery nominal voltage with me and that its only a nominal voltage of 14.8V or 11.1V, but an indication can be used in the same paragraph models, how should I choose?

Answer: a laptop computer, its working DC safe voltage range is between 5.5V to 24V. We are equipped with batteries, are required for the security of a rated voltage range. As we all know, we use the battery is lithium-ion batteries, but lithium-ion battery’s characteristics are: charging the battery voltage increased; End of electrical discharge when the voltage will be reduced. For example, for a nominal 11.1V battery, which can provide a practical and effective operating voltage range of 9V-12.6V, when the battery is full when the voltage is 12.6V or so, and when the battery discharge when the voltage of electricity is about finished 9-10V , and that means all the store to eat 9V-12.6V to use computers at work can provide an effective operating voltage. The DC power supply from the computer design principle point of view, all of the notebook computer manufacturers of computer motherboards are designed so that the power supply lines, so whether you are using original battery nominal voltage is 10.8V, 11.1V, or 14.4 V, 14.8V, can all be used interchangeably with each other, and are safe, please rest assured to use.

9. Q: How do I correct in order to achieve the best performance laptop battery?

A: The laptop battery has a microprocessor within the software, it can charge and discharge electricity when it is an estimate. Battery needs to be calibrated from time to time in order to ensure that the screen display the time and the percentage of correctness. You should first use your computer to implement the operation, done once every few months later.

(1) The first of the “Power” option set: In the blank screen, right-click, choose “Properties” – “Screen Saver” – “Power” – “power scheme” – “Portable / Laptop”, Then, “when the computer” “battery,” all the options, select “never” in the “alert” under the abolition of “low-battery alarm” and “a serious shortage of the battery alarm” feature.

(2) cut off the power adapter and use your battery power until the computer completely.

(4) Connect the power adapter until the battery is full of shows that 100%. The initial use (or over a longer-term storage later), the battery needs at least 3-4 times a full release cycle to achieve their best performance, the process of charging at least 14 hours.

Tips:

(1) You must first discharge of your battery power to the computer and then full charge to 100% of its calibrated, after which, no matter at what level the battery charge, you can always connect or cut off power supply. In addition, a period of time to do a protection circuit placed under the control of deep-charge battery capacity to compensate for statistics, but it will not improve your battery’s actual capacity.

(2) When the batteries become “empty”, the computer forced into sleep mode, the battery in fact retain a certain amount of power to ensure that the computer be able to sleep for some time. When the battery is really fully depleted, the computer will be forced to shut down. At this time, any open documents will be lost.

10. Q: Why in the first to charge the battery after 10 minutes, the computer will be displayed charging complete?

A: encountered this problem, you can refer to the correction described in section 11 of your notebook battery in order to achieve optimal performance to operate. If still not satisfied, please contact your supplier request a replacement.

14. Q: Using the power necessary to remove the battery Mody?

A: We recommend that do not remove the battery, AC power that can prevent a sudden interruption of the ongoing operations can continue while the data are not lost. If you remove it is recommended that the battery wrapped in fresh membrane and placed in a dry cool place, and I remember a month or so used at least once a battery and charge the battery in order to avoid loss of activity.

15. Q: My 20-hour rechargeable battery, the battery still appears as 0%, and cut off after the AC power supply, the computer immediately shut down, and why?

A: First of all to check the battery is good contact with the notebook, because if contact is not good, although you can read the battery of communications data, but not to charge the battery. . At this point you can take out the battery several times more than try. The battery into the computer, such as hear the beep is heard, you can be basically considered to have a good contact. Multi-try several times, you can rule out the computer and the battery being exposed problems. Especially when using the IBM computer, pay attention to this problem.

16. Q: How do laptop battery charge and discharge the battery?

Answer: Follow these steps to charge the battery discharge,
