Replacement Battery

As an important manifestation of the mobile office, the laptop’s power system is an important and fragile part. Reasons cell HP mini 210-2000 battery damage after use for some time, “aging”, the concrete expression of the resistance becomes larger, both ends of the voltage rise faster charging. So easy to charge control circuit is judged to have been full capacity will naturally decline. Relatively large HP probook 6465b battery internal resistance, discharge voltage drop, high speed, so the system is easily mistaken for the voltage is not enough, the lack of electricity. In short, the aging of the battery is a vicious cycle. Found the battery operating time is comparatively short, appropriate measures should be taken.
In addition, many lithium HP probook 4710s battery failure is the failure resulted in battery packs in a power-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent in nature with weakened for a long time after some quality begin to age, while the destruction of the whole (series after) the discharge curve. Interested readers can try to open the battery pack, and the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, the replacement under the corresponding parameters of batteries can be qualified product.
. Maintenance and restoration and maintenance, and to restore the HP probook 4530s battery, also known as “activation” or “activation, activation of the basic principles of a battery charge and discharge current must be small (too small too long), the other as much as possible to full put completely.

Charge and discharge lithium-ion HP probook 4730s battery charging at the beginning of the constant current mode, the voltage reaches a certain value to constant voltage trickle charging. The system load is large, the charging current is small, otherwise, the current from the Asus EXA0904YH AC Adapter PHR. Obviously, the system will charge the HP 614564-751 battery power will compete with the other components, such as CPU, hard disk and LCD. I have tried to run side Super, while charging the charging current between 0.70A-1.70A change, can not meet the requirements of the charging of the lithium-ion battery, so this kind of work when charging will damage the battery. IBM laptop manual HP elitebook 8730p battery charging, do not perform other possible causes, is also here.

(A) The battery causes of damage

Laptop battery use for a long time, it is often sufficient dissatisfaction power, even display the Asus A42-G73 Battery has been damaged, the specific expression of the resistance larger increase in the voltage across the charging faster. So easy to charge control circuit is judged to have been full capacity will naturally decline. Relatively large battery internal resistance, discharge voltage drop, high speed, so the system is easily mistaken for the voltage is not enough, the lack of electricity. Found the Asus G73 Battery operating time is comparatively short, appropriate measures should be taken.

(B) The battery refresh program to restore the battery discharge time

Brand laptop has a Asus G73JH Battery refresh program, we can use it to repair the battery. Example: a laptop with the battery for the nickel-metal hydride (Ni-Mh) batteries, due to the usual improper charging and discharging lead to battery discharge time is getting short, only less than 5 minutes, if carrying a laptop to work, it is very inconvenient, what can restore the battery discharge time?

The response to these circumstances, we can use the notebook official website launched battery refresh program to refresh the Asus Eee PC 1005 Battery, put it back in the discharge time, specific methods are as follows.

(1) the use of AC power for laptops, the first official website to download to a laptop refresh program.

(2) Restart the computer, press F8 to enter the boot menu and select safe DOS mode.

(3) to enter the directory where the file you just downloaded, perform a Dell Latitude E6420 battery refresh program, read the warning message, asked to insert a floppy disk, and then press Enter to execute the self-extracting operation.

(4) with this floppy disk to boot the computer screen prompted.

(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.

(6) due to the high temperature of the Dell Latitude E6320 battery should not immediately start, let the battery cool for a while, plug in the AC power supply.

(7) to boot the computer with a floppy disk, this file will automatically run the refresh program, and asks the user whether to proceed.

(8) In this case, the refresh program began battery refresh process back to the DOS prompt A:> when the refresh is complete.

(9) Turn off the computer and charge the Dell Latitude E5520 battery until the light turns green.

(10) The above process is repeated three times to get the best results.

In addition, many lithium battery failure is the failure resulted in battery packs in a power-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent in nature with weakened for a long time after some quality begin to age, while the destruction of the whole (series after) the discharge curve. Interested readers can try to open the Dell Inspiron 1564 Battery pack, and the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, the replacement under the corresponding parameters of batteries can be qualified product.

In general, very small, the sound of the computer in normal working hours, the sound of the cooling fan in addition to the sound of the hard disk read and write data, especially in switching Dell Inspiron 1545 adapter fan the sound. After long-term use of some switching power supply, while at work will produce some noise, mainly caused by poor power supply fan rotation. There are many reasons causing Dell Alienware M15x adapter fan rotation poor noisy
According to the data shows that failure caused by power accounts for about 20% of the total number of failures of the various parts of computer machine to 30%. Fault detection and maintenance on the part of the host, also must be established on the basis of the normal power supply. Let’s do some discussion the common faults of power. PC power supplyis generally susceptible to failure are the following: blown fuse in the power supply without input or output voltage instability, power output but no show boot, power load capacity. A description of each of its repair methods:

1. Blown fuse Failure Analysis and Troubleshooting

When such a failure occurs, the first to open the case of the Dell Alienware M17x adapter, check the power fuse is blown, pursuant to which can initially determine whether the inverter circuit is faulty. If so, it is not outside caused by the following three conditions: a bridge rectifier diode in the input circuit breakdown; high voltage filter electrolytic capacitors C5, C6 breakdown ·; inverter power switch Ql, Q2 damage. The main reason is because the oscillation circuit of the DC filter and transform work in the high voltage (+ 300V), the large current state for a long period of time, especially due to larger changes in the AC voltage, the output load is heavy, prone to the blown fuse fault. DC filter circuit consists of four rectifier diodes, two 100kΩ current limiting resistor and two 330uF electrolytic capacitors composed about; transform oscillation circuit is mainly composed of the two models in the same heat sink high-power switching tubes.
AC fuse blows, shutdown, unplug the power cord, and carefully observe the appearance of the high-voltage components of the circuit board breakdown burnt or traces of electrolyte overflow. Without exception, with a multimeter to measure the value of the input of: less than 2OOkΩ, backend local short circuit, and then measure the resistance between the two high-power switch e, c pole; less than 100kΩ, then the switch The tube has been damaged, to measure the resistance of the four rectifier diodes are reverse resistance and two current limiting resistor, to determine whether the normal multimeter to measure the charge and discharge. In addition, replace the switch tube, if you can not find the same model and select substitutes should be noted that the collector – emitter reverse breakdown voltage Vceo collector maximum allowable Toshiba PA3715U-1ACA adapter dissipation Pcm of the collector – base reverse hit The parameters should wear voltage Vcbo of greater than or equal to the original parameters of the transistor. Another note: must not detect a component damage, replacement will boot directly, this is likely due to other high-voltage components are still failure, in turn replaced component damage. Must conduct a comprehensive inspection of all high-voltage components of the circuit measurement, in order to completely rule out a blown fuse.

2. No DC voltage output or voltage output instability

If the fuse is intact, the load, at all levels of the DC voltage output, the possible reasons: power, open circuit, short-circuit phenomenon; over-voltage, over-current protection circuit failure; oscillation circuit is not working; power overloading; frequency rectifier filter circuit rectifier diode breakdown; filtering capacitor leakage.
The processing method; resistance to ground with the the multimeter measurement system board 11 5V power greater than 0.8Ω, then the short circuit the system board. Computer configuration is minimized, i.e. the machine, leaving only the motherboard, Toshiba PA3468E-1AC3 adapter, a buzzer, and measuring the output DC voltage, and if still no output, indicating a fault in the microcomputer power supply in the control circuit instead. Control circuitry integrated switching Toshiba PA3290E-2ACA adapter controller (TL-496, GS3424, etc.) and over-voltage protection circuit is normal is directly related to whether the output DC voltage control circuit work. Overvoltage protection circuit is mainly composed of small power transistor or SCR and related components, available multimeter to measure the transistor is the breakdown (if SCR need to weld under measurement), the resistance and capacitance for damage.

3. Power output, but no show boot

The possible reasons for this failure is “POWER GOOD” input Reset signal delay time is not enough, or no output “POWER GOOD”. Boot with a voltage meter to measure the output of “POWER GOOD” end (the computer attached to the Toshiba PA3714U-1ACA adapter plug 1 foot) +5 V output, and then check the delay components; +5 V output if so, replace the delay of the delay circuit when the capacitor can be.

4. Power load capacity

Power in to the motherboard, floppy drive power can work properly when connected to the hard drive, CD-ROM drive, or plug in the memory, the screen goes from not working properly. Its possible causes: transistor operating point is not selected, high-voltage filter capacitor leakage or damage, regulator diode fever leakage, rectifier diodes damage.
Exchange oscillation loop each of the transistors, to increase the gain, or adjust the working point of the transistor. Detected with a multimeter parts, replacement SCR, zener diodes, high voltage filter capacitor or rectifier diode can be.

From the birth of the laptops that day, the debate on the laptop 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 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 Dell Inspiron 1564 Batterymaintenance.

Laptop Battery Maintenance: activate the new battery, a battery good beginning

Many laptop are activated, which means that the new Dell Latitude E6320 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 battery inside the power exhausted, until the shutdown, and then use the external power supply charge. Home, but also the exhaustion of the Dell Precision M4600 Battery after the charge, charging time must be more than 12 hours, repeated three times, in order to activate the 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 number of Dell Latitude E6430 Battery charge and discharge is directly related to the life of one charge and put a battery, the 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 laptop battery life.

In fact, the laptop battery maintenance is basic to rely on the above two points, Here we come to talk about the dell laptop battery maintenance of several errors.

Myth one: the first time using the notebook battery three times the battery must activate it?

Generally a lot of laptop manual introduction, the first time you want the HP Compaq nx7400 battery is exhausted, before three repeated charge to more than 12 hours before maximizing activate the battery to extend laptop battery life, that have some computer enthusiasts his views, saying that doing so is not necessary. Because notebook computers have improved power management circuitry and charging management system, when the hp 6710b battery reached saturation, the control circuit will automatically switch to the off state, so long as the full line, not to say that the longer you charge you can use the longer ‘s. On this point pen think there is some misunderstanding, we can think for themselves what right and wrong.

Myth: In order to prevent the memory effect, it is necessary electricity run out before charging it?

Each charge before the Asus G73 Battery discharge is not necessary, but also harmful. Practice has proved that: the depth of discharge of the battery needlessly shorten the service life of the battery, it is recommended that when the battery is used in about 10% can be charged. Of course, when there are still more than 30% of the electricity in the battery is best not to charge, because the memory effect does exist.

Myth: laptop access to the external power supply is necessary to take the Asus G73JH Battery out to prevent the charge and discharge?

To address this issue, I think it is not that necessary, because inside the laptop comes with the power switch program, when users access an external power supply, laptop battery if the power will be in a full grid automatically cut off state, I often use laptop external power can do not have to remove the battery, also can protect laptop data loss can prevent operation when the external power outage.

Myth: laptop battery remove unused for long periods and can not maintain a permanent long life of the laptop battery?

To address this issue, we first of all necessary to understand the principle of the battery quality lithium-ion batteries for 1000 a unit of electricity, when soc> 80%, almost two and a half years of normal service life (even if you do not have a long time he will automatically discharge capacity decreases and lower will decay caused due to the battery’s internal chemical active substances, so editing is not recommended notebook battery has been hiding, not when the necessary, so as to play the advantages of the notebook Practice has proved that if you want long-term preservation of the battery, try to put a dry and cool environment and let the remaining battery power is about 40% of the ideal, of course, the best month to take the battery out to use, both to ensure good battery. save the state, but not so the runs completely lost and damage the battery.

Introduced here believe that the maintenance of hp laptop batteries have a more comprehensive understanding, in fact, maintain asus laptop battery to prevent the battery is repeatedly charged, so as much as possible with an external power supply when the external power supply instead of the first to use a period of time followed by external power, so here suggest that you use a laptop to remember that first connected the external power supply is somewhat better then boot In addition, when using the laptop battery can try to screen brightness lowered, without using external speakers, etc. to effectively extend notebook battery life.

As we all know, the HP probook 4530s laptop battery is one of the main support for laptop mobile office. Like mobile phone battery laptop battery, the earliest use of nickel-metal hydride battery (nickel-chromium batteries), was soon replaced by a lithium-ion battery. Energy storage density of the lithium-ion battery can be recharged at any time, and discharge duration (usually about 3 hours).

Rational use of lithium-ion batteries

To extend battery life, lithium-ion Lenovo thinkpad x220 battery has many advantages, but to maintain the supply of long time, also need to have some professional skills.

Initial use, the lithium-ion batteries to be three complete charge and discharge, in order to activate the chemicals inside the battery, the electrochemical reaction inside the Asus n61j laptop battery into the best condition, free to use that charge and ready to use, but to ensure that within a month the battery must have a complete discharge, depth of discharge can stimulate the activation of the Sony vgp-bps9 laptop battery performance, battery life plays a key role. If more than three months the battery is not used again before using the new battery three times a full charge and discharge, in order to ensure that activate the battery.

Setting the power management scheme

Currently the most popular laptop using the operating system is Windows 98. Windows 98 system for Dell Inspiron 1545 AC Adapter management features, and its power management features can reduce the power consumption of a large number of power consumption components to only up to meet the actual needs. The following are Windows 98, correct settings for power management:

1, the power management options.

Open the “Power Management” icon in the Control Panel, select the “Portable / Laptop” Dell Alienware M17x AC Adapter scheme. Windows 98 installation default is “always open”; Do not choose a very power-hungry “home / office desktop.

2 configuration, power management time

“Turn off monitor” option, Windows 98 default “plugged in” for “15 minutes”, “Using the Battery” for “two minutes”. “Turn off hard disks” time option, Windows 98 default “plugged in” to “after 30 minutes”, “the use of battery for 3 minutes. The computer is in a wait state exceeds a set amount of time, will go into hibernation. Dormancy characteristics of the power management will turn off the monitor and hard disk, save the contents of memory to the hard disk, and then turn off the computer. When you restart the computer, the desktop will be accurately restored to enter the sleep state before, thus reducing Compaq mini cq10-600 battery consumption.

Options can be used according to your need to make the appropriate changes. Then click [Save] button to save the program.

3 alarm settings

Click the “alarm” menu bar “low battery alarm” bar Windows 98 default is 10%, “Critical battery alarm” bar Windows 98 default is 3%, based on the need to make the appropriate changes. Click both the [alarm response] button to “sound the alarm” and “message” are selected, the “power level” is optional. So that when the Dell inspiron 1750 battery alarm limits when used, will automatically pop up a warning window, and the alarm buzzer sound to prompt the user to save the information in a timely manner.

Finally, click [OK] button to exit the Dell Alienware M11X R3 AC Adapter management settings.

In addition, if your laptop built-in infrared port, when not prohibited it can also extend the use of the hp laptop battery time.

A new battery should pay attention to the problem of initial use.

New laptop battery at the first boot, Dell precision m4600 battery itself should have more than 70% of the electricity consumption (this is common practice if you first open the notebook to purchase, found that the battery has been filled with more than 70% of the electricity that is vendor factory testing). At this point, you should be the first time the battery is full, rather than immediately, charging time must be more than 12 hours, and then set the laptop shut down when the battery 500% charge, repeated three times, so as to activate Dell inspiron 1564 battery completely, can be effective improve the battery life.

Just started using the battery, Dell inspiron 17r battery indicator sometimes scale table are not allowed, or charging long bright lights, this is because the new battery could power detection program is not synchronized with your notebook.
Second, the problems that need attention in the day-to-day use.

A how to charge and use

Please choose one of the same model or manufacturer specified power charger models, avoid the use of no confidence in power, in order to avoid unstable power supply burned notebook. Other packaging to avoid using the power adapter wrapped, causing cooling difficulties, maintain good ventilation and cooling of the battery and power adapter.

Cut off the power shutdown state, Dell latitude e6430 battery into the computer, plug in the power supply, and that is to start charging. (Note Do not handling the battery in the case of the power adapter, as this may lead to direct burn out unexpected happens notebook battery)

Charging time approximately between 4 to 8 hours, depending on battery capacity and plant design and different charging is completed, the charge indicator goes off or turn green, it is best to unplug the power supply.

Best not intermittent charging that the power supply will not plug back and forth in a short period of time, it is best to charge in shutdown conditions.

Do not mix transformers or power supplies, each operating voltage or the charge voltage of electronic products may be different, may be using the wrong battery damage, serious but also makes the machine burned out.

If charging is complete after 30 minutes and then use the battery to Asus g73jh battery might be better.

7 computer batteries use more main lithium-ion battery, and its biggest advantage is that there is no memory effect, so users do not have to worry about this problem, can also be charged if the power does not run out, but it is recommended that users occasionally battery warning to the system power , and then perform the charging helpful to battery reliability.

If prolonged use of the power supply as the power supply, it is recommended to remove Asus a42-g73 battery, and a separate power supply operation, the need to go out to use the computer and then loaded into the battery.

Do not battery pack as the other power use.

Do not attempt to open or service the battery (except for professionals), sophisticated control circuit within the battery, the violence is likely to cause damage to the delicate circuitry contains a lithium-ion laptop battery, use or mishandling may explode. Market performance for the core services maintenance battery, replacement very unstable.

Do not battery and keys scattered metal substances placed together to prevent Asus A32-F82 battery from being accidental short circuit.

Do not use in the bed, sofa, carpet and other flexible surfaces to be careful not to obstruct the notebook already good heat dissipation. And also generate static electricity, bed towel like indirect damage to the notebook internal components.

13. Install the notebook comes with power management software, are better able to play the role of Asus k72 battery and the protection of the battery can also be on the Web search.

14 download battery management can be more convenient to check the laptop battery usage.

Does not matter, the machine, Dell Inspiron 1564 Battery did not influence my buddy had made ??a phone call to dell customer service asked, if the battery is not full, it will enter the state of charge, the battery is full, the machine self-energy chip automatically switch to an external power mode, that is, no longer to charge the battery directly to the machine powered. So the landlord do not have to worry about.
So with comparison Province battery, at home, no problem. But answer the adapter, do not connect Dell Inspiron N5010 Battery, in order to avoid harm to the battery.
You said, is divided into two: the Asus ADP-90CD DB Adapter electrical connection at the same time, the laptop battery is installed in the notebook: notebook shutdown, power adapter not unplug. The first notebook battery life is certain, recommended If they do not use the battery, you can charge the battery in about 70%, and then take off laptop battery save, store about two months The time out used once, and the need to fully charge and discharge. Principle from the battery to work, which helps extend battery life. The second, in the off state, the Asus EXA0904YH adapter has an external 220V AC If you disconnect the interface connected to the host, so that when there is no impact, because this time in the case of no-load power adapter , no current flows through, not caused by the load on the circuit in the adapter, If you do not disconnect the interface on the host, then the Toshiba PA3714E-1AC3 adapter is current through the Dell Inspiron 1545 Adapter itself is a transformer, The current through there are losses, the impact of their life there. I hope you …

1 read the user manual carefully before using the laptop batterymaintenance part;

2 first charge, you should continuously charge Dell Inspiron 1545 battery to 12 hours, and cycle to fully charge and discharge three times to fully wake up a new battery;

3 If you use an external power supply for a long time, it is best to remove the battery. Many of my friends did not notice this problem, do not remove the battery with an external power supply not only affect Dell Inspiron N5010 Battery life, notebook computer also allows the heat burden becomes heavier, shortening the life of the laptop;

4 regularly charge and discharge. Even without the memory effect of lithium-ion battery there is a certain inertia effect for a long time not to use lithium-ion loss of activity, need to re-activate. Therefore, if a long time (three weeks or longer) do not use a computer or find that Dell Inspiron 1564 Battery charge and discharge time shorter, should be fully discharged before charging the battery, usually a month to at least complete charge and discharge times.

Best to turn off charging laptop, the battery can be fully charged, do not unplug the power drop in the charge. Charge off charging to shorten the charging time more than 30%, but also extend Dell Inspiron 1370n battery life of more than boot. Best in the charging is completed 30 minutes before use.

Prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid Dell Inspiron 15R Battery contact with metal objects touch the occurrence of a short circuit.

Lithium battery charge and discharge is generally not more than 800 times on one charge, it will shorten the time of life. Is recommended that you use an external power supply, if you use half-way multiple plug Asus ADP-150NB D adapter, and the laptop did not pull out the built-in battery, will make the battery life shortened because every time access to the equivalent of an external power supply to charge the battery once.

7. Optimization settings for power management options

For laptop users, we recommend the use of the Windows XP operating system, of course, if the configuration of the laptop is too low can not even meet the the WindowsXP minimum configuration requirements, it is another matter. There are many reasons, the main thing is the laptop’s power management is currently the most advanced of all computer operating systems, together with the Centrino platform so much the better. 1.6GHz Pentium-M load is small only work in less than 600MHz frequency. If your Asus EXA0904YH ac adapter Intel SpeedStep, AMD PowerNow  or Transmeta’s LongRun technology, we must remember installed the latest drivers, to play its biggest utility, WindowsXP is automatic, you can follow its own requirements in terms of performance and The power to find a balance.

The user can do the optimization of the power management settings:

1) Do not use a screen saver.

2) the Asus F52 ac adapter, select the “Portable / Laptop” reasonable set following the time according to your needs, each situation is different, the inconvenience made mandatory. Time to turn off the hard disk is generally slightly longer than the standby time, so as not to affect the hard life.

3) Go to the “Power Options Properties” Advanced “fair use” power button “, can bring you a lot of convenience, can also enhance the rational use of Dell Latitude E6430 battery endurance. For example: “In closing the portable computer” is set to “standby”, leave the laptop for a while, only power but also of great help to the confidentiality of personal information, and do not need to wait for the time to restart. For the use of the first-tier manufacturers of laptops (such as IBM, SONY, HP, Toshiba, etc.), usually provide better power management software, and has some special features: IBM power management program can reduce the LCD screen refresh rate; TOSHIBA Toshiba’s power management program can turn off any device that you specify directly in the case of power shortage; SONY dedicated power management program can set the running speed of the cooling fan, you can also turn off the IEEE1394 interface, and MEMORY STICK slot, in order to achieve the purpose of power saving.

Energy saving of 8. Hardware

1.Redirect the Old pages to the New ones

Once you upload the content on the new website you will need to place redirects from the old domain to the new one : laptop power supply. Note that this should be done on the page level, meaning that each page of the old site should be redirected to the new URL of the page on the new domain. Map each page to the appropriate new URL and don’t just redirect all of them on the new homepage.

It is strongly recommended to use 301 redirects because in this way you manage to pass to the new website most of the metrics, characteristics and statistics (PageRank values, links, anchor text data etc). Nevertheless note that 301 redirects should be used for permanent changes. If your plan to undo this change on the future you should use a 302 redirect (note though
EG:
we make htaccess file,detail as follow:

# BEGIN
Opions +FollowSymLinks

RewriteEngine on

rewritecond %{http_host} ^olddomain.com [nc]

rewriterule ^(.*)$ http://www.laptopbatteryadapters.com/$1 [L,R=301]

# END

2.Use the Change of Address tool in Google Webmaster Console

Another thing that you should do is use the Change of Address tool in Google Webmaster Console. After registering both the old and the new website to Google Webmaster tools you should specify that the old one has been transferred to the new address. The Change of Address tool works at the site level, which means that it clearly helps Google understand that this transition happened for the whole domain and not for specific pages of your site.

3.Update the important Backlinks

Even though the 301 redirects are supposed to pass most of the PageRank and anchor text data, it is strongly recommended to try to update the most important backlinks (links from reputable sources with high PageRank) that point to your old website and link directly to the new pages. Of course you don’t have to contact all the webmasters that link to your website, but instead focus only on the most important ones. In order to get a list of all the Backlinks of your website you can use the Backlink Analyzer tool or Google Webmaster Tools console.

when i update my website,we not update the important backlinks,it is too troublesome.

4.Be patient & Keep it up-to-date

Changing your domain name is among the most major updates that you can do to your laptop ac adapter website. Be patient and make sure you dedicate time to test everything before you transfer your whole website. Also make that you will renew your old domain names regularly and that you will not let them expire. In this way you will not lose any referring traffic or PageRank that is coming from old backlinks. Last but not least don’t forget to maintain the 301 redirects from the old domain to the new one and to renew the change of address every 180 days.

we have changed the domain 1 month: the organic traffic loss vast.many keyword can not find,the old domain has no results.but the new domain also has no rank.such as: laptop ac adapter, dell ac adapter, dell pa-10, dell pa-12,toshiba pa3468u-1aca,toshiba ac adapter,sony vgp-bps9/b,sony vgp-bps9/s.

only few keywords can has page rank.we will test it then and show the result
