laptop and notebook

1. Battery factory, manufacturers have been activated to deal with, and the pre-charging, the batteries have more than electricity, a friend of mine said that the battery in accordance with the adjustment period recharged, the standby is still a serious shortage of the assumption that the laptop battery had to be really authentic, then the battery, in which case Adjustment period should be extended for a further 3 to 5 times full charge and discharge.

2. If you buy a new cell phone battery is a lithium-ion, 3 to 5 times before the charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion battery memory effect did not, but there is a strong inert, should be fully activated in order to guarantee the future be able to use to achieve the best performance.

3. Some automated intelligent rapid charger when the lights change direction, said only 90 percent full. Charger will automatically slow to change with full battery charge will be. After the battery will be full of the best, otherwise they will be used to shorten the time.

4. Charging, lithium batteries do not need special discharge, discharge improper compaq battery will be damaged. When charging as much as possible in order to slow Chong Chongdian to reduce the fast charge mode; time not more than 24 hours. After three to five times the battery fully charge and discharge cycles of its internal chemicals will be all the “activation” to achieve the best results.

5. Please use the original or the reputation of a good brand of chargers, lithium batteries use lithium battery charger dedicated, and follow the instructions that would otherwise damage the battery or even dangerous.

6. There are a lot of users are often in charge when the phone open, in fact, it will hurt the mobile phone is easy life, because in charge of the process, the cell phone circuit boards will be hot at this time if there are external phone, you may have a moment Current return on cell phones within parts of the damage.

7. The battery life determined by the number of repeated charge-discharge, so to avoid battery power than when they charge, which will shorten the Presario R3000 battery  life. Phone off for more than 7 days, the first mobile phone batteries should be fully discharged, adequate electricity and then use.

8. Phone battery self-discharge exist, not when Ni-MH battery will be a day of surplus capacity by about 1% of the discharge, lithium batteries a day by 0.2% to 0.3% discharge. In the battery to charge, try to use a dedicated outlet, and the Chargers do not share household electrical appliances such as TV outlet.

9. Although the mobile phone network coverage in the region, but in the mobile phone charger off when the phone is no longer acceptable and the call. At this point, you can use the phone did not pass the transfer of functions will be transferred to the mobile phone side of the fixed-line, to prevent the loss of calls, this method is not for the mobile phone network coverage area or a weak signal and being unable to get through when applicable.

10. Do not expose the battery at a high temperature or cold, like a dog day weather, should not be on the phone in the car, stood in the scorching sun exposure; or get air-conditioned rooms, air-conditioning on the direct blow. When charging, the A2 battery  a little heat is normal, but it can not be Jinshou high temperature “suffering.” In order to avoid this from happening, it is best at room temperature for charging, and not to cover anything on the phone.

11. Nickel-cadmium (n icd) before the battery must ensure that the battery completely dead, after the rechargeable batteries need to ensure adequate electricity.

12. If the cell phone not to place too long, to the best cell phone battery to the maintenance department to apply for a living to deal with, you can own a constant voltage direct current, voltage adjustment for the 5 ~ 6v, current 500 ~ 600ma reverse battery connector . Note that the liberalization of touch, up to be repeated three times, after such treatment, re-use original charger “adjustment” charge.

13. The longer the time when the charge is not good, not for the protection of the circuit full battery charge should be stopped immediately, otherwise the battery overheating due to heat or impact on performance.

14. Lithium-ion A3H battery  charger must be selected precincts, or may fail to saturation, the impact on its performance. After the charge, should be avoided to place the charger in more than 12 hours over a long time do not have to be separated so that the battery and phone!

With the development of automotive electronics in the next 10 to 20 years car will be amazing. The biggest change is beyond the scope of automotive electronics, depend on the realization of the power-driven car. Not so much power and software changes in the car than it is to become electric car. In other words, the future of the automobile will be connected with the power system. The traditional gasoline engine and hybrid cars into plug-electric hybrid, ultimately to the development of pure electric vehicles blueprint for the development of more and more realistic. The evolution of motor vehicles, electronic technology which will play a key role?

Not so much power and software changes in the car than it is to become electric car battery .

Of course, the other is the realization of the development blueprint. For example, there are clean diesel and bio-fuel vehicles. Fuel-cell vehicles to sing some of the feeling of a supporting role. As long as adequate infrastructure to improve power supply, electric motors can be said to be an ideal means of transport drivers actuators, the train has been 100 years ago is proof of that.

To consider the case, even in the blueprint for the development of all in comparison, the hybrid-electric hybrid plug through the stage to the final development of pure electric vehicle that’s highly competitive. This, of course, the existence of soaring crude oil prices brought about by promoting the role, with the Hokkaido Toyako summit approaches, this approach has become more clear.

Power system connected with the car after the performance of motor vehicles will also change. Automotive will be the “number of short-time charge of traffic, similar to the light rail transport.” Train and car What is the difference? While the train was traveling from the external side was able to
The volume of transport, while the car is put on the road most of the energy transport.

Traditional car full of gasoline for traveling to 400k ~ 500km, a speed of up to 160km. Because the car manufacturers to achieve the goal of “anytime, anywhere who” can drive the car. However, not all is the automotive need this level of performance then? Taking into account the reality of use, in fact, many people believe that the car needed only 1 day traveling around 20km per hour up to about 100km.

Traveling in a row with 400k ~ 500km car is even in the central Sahara desert sand out of the desert can also be configured performance. In urban driving such vehicle is indeed a waste. Whenever talking about the topic of low-storage car, some people say “run out of energy in the event broke down how to do,” but how many people will go when they broke down in a place where it can not charge? People only need to choose their own needs laptop battery .

In the above-mentioned evolution of the automobile, electronic technology which will play a key role?

Experts interpret】 【

Horiuchi Yoichi: electronic technology will become the electric car

If the vehicle access to the electricity system, “Short-term driving charge on many occasions”, then it is up to test their abilities of a capacitor  hp-f2024b.html”>F2024B battery . Use of electric car drivers, can not rely on the track as the train along the line of aircraft power supply at any time. Can not be like the gasoline engine vehicles as store traffic 400k ~ 500km for energy. As a result, need to be able to cope with the building of a small amount of energy supply to the power supply infrastructure. Car carrying only a small number of fast charging and discharging of the energy source can be.

In that case, this energy source is rechargeable battery or a capacitor it? I personally feel better capacitors. Capacitor can be fast high-current charge that attractive. While rechargeable  Toshiba battery   discharge faster, but the charge time is too long.

The use of rechargeable batteries to the hybrid-electric plug, for example, need to go home after charging 1 to 2 hours. Although in the near future may be reduced to 15 to 20 minutes or so, but still very long. The capacitors just 30 seconds to complete the charge. However, if the accumulation of too many capacitors charge also requires a longer period of time, it should carry a small amount.

Capacitors and other characteristics: no charge and discharge of chemical changes in the product’s long life; terminal can be left to determine the correct voltage; non-use of heavy metals, such as small impact on the environment. Although the energy density as lithium-ion rechargeable battery, capacitor, but with the progress of technology development, followed by the possibility to catch up.

Today’s DC batteries used in general there are 2 kinds: special lithium batteries and 5 AA batteries (nickel-metal hydride rechargeable batteries most commonly used). Lithium-specific power, light weight, high capacity, environmentally friendly, virtually no “memory effect”, but very expensive generic poor, and a lot of fakes. Ni-MH battery has a high capacity, the depth of discharge, have been resistant to excessive discharge and charge, charge a short time, and so obvious advantages. The most important thing is nickel-metal hydride batteries are cheap, high universality.

   No matter which type of battery, as long as it is with the sales of DC, in a general statement, there will be a matter of the use of attention, and some companies even printed a separate laptop battery charger and the use of a guide. Note that these are some of the most basic but very necessary for the maintenance of way, such as rechargeable batteries should choose the way of charging time, and so on. Unfortunately, quite a number of these that are often ignored and shelved. : The new DC, to spend some time reading these guidelines, it is absolutely necessary.

   Ordinary users in the use of DC, the batteries are not the exclusive use of storage bag; users to replace the battery after the customary battery placed at random, regardless of whether or not the release of the place clean, damp. The consequences of such a battery is easy to dirty and easy contact with the metal (such as keys), and other contacts, easy to damp, and these are the enemy of batteries. : Users should set up a special cell to place, maintain and clean the HP-laptop-battery/”>pavilion battery. In order to avoid problems such as loss of electricity to keep the battery at both ends of the contact point and the internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.

1, sometimes their own cell phone charger and the battery is full display, and the actual use of a very short time, there is no laptop battery power, how it is going on?

There are battery memory effect, such as: the aging batteries and nickel-cadmium batteries will lead to more cases. For example, a full glass of water, it is frozen, liquid water would be gradually turned into solid ice. Although the ice is not drink the water. Memory effect is similar to “freeze the liquid water into solid water” so that power can not be used, above, due to the effects of memory or battery state, so that power can not be translated into, so although the phone shows the battery power Full capacity, but only a very short period of time.

2, how to prevent the battery memory effect?

Very simple and takes only a per-use mobile phones when the battery completely finished on the use of the line. This will greatly extend the battery life.

3, when the compaq battery memory effect can try this approach?

① battery with a newspaper to wrap a plastic bag and then put into freezer Overwrapping good for three days (newspaper can absorb excess moisture).

② out after three days at room temperature for two days decentralization.

③ two days after the battery charge, full charge after the mobile phone rolled into the test (estimated to save 80% -90%).

4, the battery does not charge the causes and common-sense solution?

(1) and the battery charger connection is not correct, the right to be connected;

(2) Contact the battery charger or not clean, need to clean and dry;

(3) battery has been aging and need replacement batteries.

5, battery power faster than normal, common-sense reasons and solutions?

(1) weak cell phone signal in the negative coverage area so that the power consumption accelerated in the normal coverage area, no problem.

(2) mobile phone antenna in use did not open, so that the power consumption to accelerate the use of cell phone antennas formed out of the habit of saving can be.

(3) a new Presario 1200 battery  or a long-term non-use of batteries used in the first three times before they could cross to the normal standards of performance.

(4) of the old battery, or battery memory effect of battery power will be finished within a very short time consumption, the need to replace batteries at this time.

(5) batteries used in extreme temperature, low temperature or high temperature can greatly affect battery performance, often take charge.

6, battery maintenance of a few common sense?

(1) in order to extend battery life, the charging time can not charge more than the necessary period (5-7 hours); but the first three of the new battery to be used to discharge the phone automatically shut down after the 8-12 hour rechargeable ! In order to ensure that the battery capacity was sufficient to stimulate them;

(2) only when the purchase of the original factory charger;

(3) the Presario 2500 battery  does not contact with the metal with oil or contact accessories, pay attention to moisture;

(4) batteries should not be dipped into water or thrown into the fire;

(5) Do not put batteries, such as low-temperature refrigerator, such as high temperature next to the stove;

(6) to deal with the battery, use of special facilities;

(7) For the battery exchange, only recognized by the cell phone battery types;

(8) to have the memory effect of batteries, each should end the use of electricity, rechargeable, battery Otherwise, there will be memory effect, greatly reducing Presario 700 battery life.

(9) battery life is normally sufficient to calculate the number of release, and therefore, adequate electricity, run out of electricity, to the maximum extend battery life.

Notebook battery maintenance mode. . . . What is the use of laptop batteries and maintenance of the taboo? Maintenance of notebook batteries in the end not to be pulled out books, out of power if the how to do? If the laptop battery maintenance of good words to use up to how long? See below, it will know. Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must use some attention to the maintenance tips: Whether you use the laptop’s lithium notebook battery or Ni-MH battery, battery power as much as possible to use the basic And then do charge (less than 5% of electricity), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours.

Battery life of notebook batteries, not by the total length of time, but by the charge and discharge to determine the number of times. Here is the notebook maintenance. If the battery will always be loaded to a notebook instead of taking down, even if the machine shut down and remove AC power, the battery would not like to imagine what it has been full of electricity when the state. As the laptop battery in the battery in the integrated control circuit, so even if the computer is shut down when power is power. As the one connected to AC power, rechargeable battery will begin whenever the power turned on or off, your laptop compaq battery will be recharged repeatedly and discharge affect battery life.

To this end, the use of external AC power supply when it is best to unplug the battery, or notebook battery for a long time in a state of fever have an impact on their life. To maintain the battery, do not have long-term, at least 12 months a red discharge in order to ensure its activity. In the custody of the battery when there is a need to pay attention to. At present, the vast majority of notebooks used in lithium-ion battery for a long time, if not in use, often prone to excessive discharge, may no longer be able to charge batteries for notebooks. In order to prevent the excessive discharge, in a state of semi-charge save in cool dry place, and then once every six months, and then the necessary and sufficient electricity to half of the state.

In addition, the impact on Presario 2500 battery  life books of factors including the use of the environment temperature (30 ℃ suggested that the use of the following), storage batteries and the battery temperature suffered shock, such as size. Notebook batteries in use for some time would be after the aging (how maintenance is the same), the specific performance of the resistance is bigger in charge when both ends of the voltage rise faster, so that was easy to charge control circuit has been judged to be full of , The natural capacity is lower than before. The notebook battery is a correction to deal with the aging batteries effective way to a small number of notebook batteries have the exclusive use of correction software. If your notebook does not discharge the exclusive use of software, so the battery can be in accordance with the following steps for maintenance:

● screen saver will be banned;
● In the Windows power management will power scheme is set to “always open”;
● alarm at the tab will be “insufficient power warning” is set to 10% of the operation is set to “operate”;
● will be “a serious power shortage alert,” set to 3% of the operation as a “wait”;
● the screen brightness to the maximum;
● confirmed that all the windows closed, and save all the data before work;
● confirmed that the battery charge in more than 80%, pulled out all external power supplies and equipment.

Discharge after the end of the notebook will automatically shut down after the power supply will be planted to allow notebook charge, the process can be repeated 2 to 3 times to enable the continued low current Presario 700 battery  discharge, which discharge in the state of our day-to-day use is not possible Achieved, the effect of the discharge and those dedicated basically the same software.

Q: What kind of notebook can provide a longer battery life time?

DELL engineers: only low-value CPU frequency is wrong thinking to choose, because the selected components such as LCD can achieve energy-saving, and CPU can be dynamically adjusted according to application frequencies, it can not value the “Ultra Low Voltage.” In comparison, high-capacity battery configuration of the mainstream Centrino notebooks performed well, if conditions allow, can be equipped with the best recommendations of the second block the use of batteries. Usually use the same battery, the time to go out with the original battery. In fact, to buy a piece of notebook batteries are not expensive, you can find those brands are specifically to help manufacturers who wish to purchase. Those manufacturers because there is no pressure on the brand, so prices less than the general.

The proper use of batteries do not know whether all know? We will use the battery in the right way to carry out the sum, and we share so that everyone with the correct approach to maintenance and laptop battery.

     In addition to the attention Buy mobile phones look and performance, we are more concerned about the length of standby time, no one spent much of the price it is willing to wait a day to recharge your cell phone! Many consumers complain Phone standby time of the publicity has not done in a long, but discovered carefully about the exchange of original Charging its way, but it is wrong, the wrong charge resulted in the short battery life in mobile phones complained that the issue of standby time in 40%. Accounted for 50% of consumers are some cheap process, and the purchase of the poor quality of the battery charger or assembly. Here is not to say that the assembly can not buy batteries, but said that the battery assembly also graduated. To buy the poor quality of standby time on the nature of the short. Today, fish is not to teach you how to distinguish between good and bad of a battery, but to teach you the correct treatment of mobile phone batteries, which is the correct charge skills, in order to truly play TV mobile phone you use time as well as the life cycle.

     As mobile phones an indispensable aspect of mobile phone batteries were presented as a standard configuration, which called the original battery cell. But a power is unable to meet consumer demand for day-to-day, so business will be given a battery assembly. Importers assembled by the sending cell is the basic number of domestic hp battery manufacturing companies, the quality of the letter over. But there are a number of JS with a number of small factories will be producing the battery assembly replaced the original battery shell original equipment batteries to consumers, consumers told to send the two former electricity. Fish here to teach you a little trick: look at the cell-chip, chip of the original bright and shiny, the group is more dark, in order, the original compact, the group is more sparse. Good selection of the battery, then we should also look at the skills of charge.

     Both the original cell or battery assembly, manufacturers have been activated to deal with, and made a charge, so you get the battery, battery power is there, the manufacturers have been activated to deal with. We have the complete mobile phone charging and discharging of the battery called a period of adjustment. However, It should be noted that if consumers buy the phone for the lithium-ion battery, then we 5th ~ 3 as the adjustment period recharged, this time we should charge more than 14 hours in order to ensure full activation of the activity of lithium-ion and lithium-ion batteries No memory effect, but there is a strong inert, fully activated, you can use to ensure that in future be able to achieve the best performance.

     Said the battery charge after skills, but also talk about the role of the charger. Consumers use the charger in the so-called automated intelligent fast charge of the Chargers, here we have to note that when the lights change direction, said only 90 percent full, this time of the charger will automatically change to use the slow charge The F2019B  is full, so we use this type of charger when to be patient, and so on one end of the time, so that it will not shorten the battery life. At the same time, the charger in the purchase, it would be best not to yield to the temptation of cheap small, select a good brand or reputation of the original Charger (Li-ion battery to use a dedicated lithium battery charger) and follow the instructions to carry out that charge. Would like to remind the user to use lithium batteries, lithium batteries do not need special discharge, charging as much as possible in order to slow Chong Chongdian to reduce the fast charge mode, charging time at the same time not more than 24 hours. Also mentioned in front of lithium batteries to charge and discharge 3 to 5 times will be “activated” to achieve the best results.

     We are in charge when there is a very bad habit, if not in use Wall Décor & Hangings, direct phone charging like a mobile phone when driving, fear fumble phone messages and, in fact, it will hurt the mobile phone is easy life . In charge of the process, the cell phone circuit boards will be fever, if in charge when the phone might have a moment to return current, so the phone’s internal parts have a certain degree of damage. The F1739A  life determined by the number of repeated charge and discharge, when you phone off more than 7 days, you need to do is to fully discharge the battery cell phone, and then the use of adequate electricity. At the same time Please note that the battery should not be exposed to severe cold or under high temperature.

     Finally, I had to remind the charge time is not good, the longer the battery will heat or overheating of its impact on the use of the performance.

Motherboard battery failure

The laptop battery is dead motherboard cause of computer failure can not be started, see dell battery.

A telephone rings, I awakened from a dream that a friend’s computer problem: press the power button, the computer and nothing happens repeatedly press the power switch is still invalid. After my initial analysis, is likely to be part of the problem of power is not enough power (power of low-grade “patent”) is a short-circuit switch, Collect a variety of tools for a pretty good idea after a friend went straight home.

Indeed, such as friends above, no matter how pressing the power switch (socket and verify that there is good access to electricity), the computer just like wood, like the “one drop of a hat.” Computer does not have any alarm sound, the motherboard does not seem to load the required voltage, power supply fan is not moving, it appears that the computer simply will not be able to power up. Open the chassis closer look at the motherboard and power supply connections and there is nothing abnormal, the power switch is also not short-circuit signs readily connect to other parts again still boot failure.

As the power of “suspects” the greatest, I have decided to replace the method used to verify, just-on-hand to have a 250W power supply, installed after the computer is still “silent”; Is this 250W power supply is Li dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery? At this time I noted the chassis installed in the four IDE devices: two hard drives and two CD-ROM. Friends said that just to upgrade, it appears that is likely to be caused by excessive power supply, two of which I immediately unplug the power plug of equipment, try to boot, the computer has not the slightest reaction.

While I am prepared to give up when suddenly the computer’s power supply fan spinning up, then heard the sound of the hard drive self-test, the display is also slowly changing light, the computer launched! But soon, start interrupting, showing “CMOS Load Failure”, and prompted by the “F2″ key to start, according to “Del” to enter the BIOS settings, no matter, I press the F2 key to enable the system to continue to guide, but in any case can not enter the Windows XP desktop, had to restart. The press “Del” key to enter the BIOS settings, friends trying to enter a password, but directly to the, and found the time to view positioned at 0:00 on January 1, 1999, and it is clear the CMOS gd761, td347, dell inspiron 6400 battery is dead . Immediately bought a new battery into one, and all equipment connected to the boot again, the smooth startup of the computer, but still showed “CMOS Load Failure”, had no choice but to enter the BIOS settings to choose “Load BIOS SAFE DEFAULTS” and restart the smooth into the Windows XP desktop, and all the restoration unabated. In the thought that the problem has been resolved, the friends suddenly find missing floppy drive icon, the system did not identify the floppy! Is just now beginning to think that the song might touch the floppy drive connection, so no choice but to open the case more thin, but still can not see the boot floppy. Calm down, just recall the operation “Load BIOS SAFE DEFAULTS”, the floppy drive is set to the default “None”, and restart to enter the BIOS settings, was to prove my idea to come back immediately, with a floppy drive while .

Recalling the whole process, everything is small CMOS battery to blame, it seems that analysis can not be in accordance with the experience of walking, but should be adaptable, to deal with the specific environment; as to why no power CMOS, the computer can start suddenly, Although my analysis may be connected to power after the computer does not start, but the power supply has power to the motherboard, the motherboard CMOS battery to be sufficient dell inspiron e1505 battery, dell inspiron 6400 battery power to start the computer, they have taken place in front of the scene.

Beijing on September 20, according to foreign media reports, Apple recently said the company’s version of the iPhone will be 3G mobile phone users to replace the charger, because the company received complaints that the metal charger from the power outlet in the spring off , Resulting in electric shock.

Apple said the company received a similar complaint only “a very small portion of the sale of chargers,” and there is no report of casualties. The existence of potential safety problems with the charger is all the iPhone version of the 3G mobile phone charger attached ultracompac UBS, its sales in the United States, Japan, Canada, Mexico and some Latin American countries. Europe and other parts of the sale of the 3G version of the iPhone will not be affected.

Since Oct. 10, above the relevant market users to the local Apple site or Apple’s retail stores to replace the charger. In the Apple Web site, the company released security bulletin recommends that customers using USB cable, through computerization for the 3G version of the iPhone charge, or choose another of UBS with a copy of the charge, as well as on-board charger power supply charge. Apple’s Web site announced the details of the replacement program

Yuzhong District of Miss Fan asked: I use in notebook computers is often directly connected to a fixed power, the notebook’s battery configuration is always no access to, I would like to ask how best to preserve access to the battery?

Xiao Bian: You can charge or discharge notebook battery to 40%, and then on 15 to 25 degrees Celsius temperature of the Department to preserve dry, the temperature is too high and too low are easy to speed up the aging ibm-thinkpad-r30.html”>ThinkPad R30 battery. In addition, because the vast majority of notebook computers used lithium-ion battery for a long time, if not in use, often prone to “excessive discharge”, may no longer be able to charge for. Therefore, if the laptop battery needs to be shelved for a long time to save, then left in the battery to ensure a certain degree of power could be at least a month on a full battery charge and discharge, and then save the above-mentioned methods.
