Acer Emachines Laptop Battery Maintenance
Laptop Battery Maintenance
1, activate the new battery. You want your notebook battery longevity, there must be a good start, which was to buy a notebook from the start. Acer Aspire 7750G battery New laptop batteries at the first boot with 3% of electricity should be (this is common practice firms. If you buy the notebook first opened, found that the battery is fully charged, is certainly used by others), this time, you should first do not use external power, the battery inside the power exhausted, until the shutdown, then use the external power supply charge. Acer Aspire 7750Z battery After returning home, even after the exhaustion of the battery charge, charging time must be more than 12 hours, repeated three times to activate the battery, in order to lay a good foundation for future use.
2, to minimize the number of EMACHINES D440 Battery. This method seems to be some people feel stingy, but it is also the most effective. Acer Aspire 7750ZG battery You know, the battery charge and discharge directly to the life of each battery charge, battery on a step forward to retirement. Recommend you use an external power supply, use an external power supply when the battery removed. Some friends of convenience, often several times a day the power plug, and the laptop is equipped with batteries, do more damage to the battery. Because each time access is equivalent to an external power supply battery charge time, battery life shortened by a natural. Acer Aspire AS4250-C52G25Mikk battery
3, after the exhaustion of battery charge and avoid charging time is too long. Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power must be exhausted after the full (capacity less than 1%), which is the best way to avoid the memory effect. No memory effect on lithium argument, I note in front of businesses irresponsible misled. Lithium also have memory effect, but its memory effect than Ni-MH small number of Bale. Acer Aspire AS5250-C52G25Mikk battery And battery charging in the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent erosion chemical liquids, avoid contact with the battery contact with metal objects such as notes, much to mention here also.
The first charge, you should continuously charge the battery to 12 hours, and cycle to fully charge and discharge times (see the battery maintenance section) in order to wake up completely new battery, if this is not the battery is stored for a few months use, it is also recommended for three complete charge and discharge.Acer Aspire AS5250-C53G25Mikk battery If a battery by 12 consecutive hours after charge and discharge cycles, or three times still can not charge this battery can not be used needs to be replaced.
Laptop computers are used in the current lithium-ion battery as its power source, not equipped with the battery for a notebook, the notebook has completely lost its own meaning, and a mobile PC is no different samples, so that the notebook computer notebook computer battery is the very important qualitative components. Acer Aspire AS5250-E352G32Mikk battery
Avoid the use of lithium batteries under high temperature, expert studies, high temperature conditions will accelerate the aging process of lithium batteries, and not to the same extreme low temperature environments. Low temperatures will reduce the activity of lithium EMACHINES D442 Battery to reduce laptop battery life. Activate regular lithium treatment is fully charged and discharged, so that the maximum capacity lithium recovery. Acer Aspire AS5253-C52G32Mnkk battery Approach is to turn off all power management, so that slowly discharge until the laptop is fully discharged and then fully charged, can be repeated two or three. Hot weather, as far as possible safeguard their own laptop batteries, notebook computers also allow better play their role. Want to maintain your laptop battery will not become part the trouble.
Laptop battery notebook computer can be said that the most important source of inspiration. Acer Aspire AS5253-C54G50Mnkk battery No batteries to provide energy, you can not complete the special requirements of mobile office. Then we can only laptop in the hands of a mobile PC Bale. The laptop battery maintenance and use of skills has become the most difficult thing for most consumers. Acer Aspire AS5253-E353G32Mnrr battery Now in use and maintenance of laptop batteries have been different opinions on this issue, I now combine their own experience and advice of a Taiwan-based notebook brand customer service center engineer the battery after use and maintenance of this situation, and so a brief introduction, and will be in-depth discussion of my friends in the laptop battery maintenance and daily use in the presence of some errors to do some corrections, hoping to help our friends. Acer Aspire AS5253-E354G32Mnkk battery However limited, the article if oversight is also beg the indulgence of our friends look!
There is also a need to pay attention to the question: if long-term battery-powered and not powered with AC adapter (such as students), put the battery in a cool dry place such as cabinets. This approach is to avoid humid environment, while if the machine not the best place to separate the battery and the books, do not believe we bought a time when attention to cell phones and books to see, business is not separated from the battery and the machine's? Acer Aspire AS5741 battery
hang up, but there is no way to pull the battery
I have seen some friends before the machine can not properly shut down the phenomenon, even illegal shutdown are not effective, Blame the great "fainted dead" system now! Finally her brother directly to one-third to pull the battery with eyes closed two stamping feet, and heard books scream would stop. Acer Aspire AS5741-H32C/S battery In fact, this approach is very harmful, because in the standby state, the memory is powered and working, if hasty to take down the battery directly, data loss is inevitable, not in the plug when the AC adapter to take the EMACHINES D640G Battery This approach can only be a hundred harm

ASUS K53SK K53SM Notebook Battery Review Acer Aspire AS5741-H32C/SF battery
From the test results can be seen, which hard disk write speed almost the height of the read speed, which require a higher speed in accessing the user is indeed a good news. The test from the write speed of 154.6MB / S.
As the main target of this evaluation is the card with the ASUS Array SAS hard disk transfer speed test, since it is for speed, then we will need to explore its fastest, the best place in the end where they are. Acer Aspire AS5741-H54D/LS battery We all know that a few hard drive RAID0 works in parallel processing, accessing the data, respectively, by the simultaneous operation of several drives, read and write their own parts, so the speed is the fastest. Sorry is the way I only have two hard drives, we can only explore two hard disk drives is the speed of a ASUS K53SK Battery .
The following two sets of test data are derived from RAID0 data read and write speed, the speed reached a 295.6MB / S and 286MB / S, compared to a single hard disk read and write capabilities, almost doubled in real times, which can be regarded as a consistent theory and practical special case, RAID0 read and write performance really extraordinary. Acer Aspire AS5741-H54D/S battery
The following test replacement PIKE 1068E card, the protagonist of this evaluation, the official debut-PIKE 2008 card. The main test here two cases, first, PIKE 2008 SAS I drive card with read and write performance tests to verify the card downward compatibility PIKE 2008; Furthermore, the test card with PIKE 2008 SAS II hard drives, and explore its highest reading write performance. Acer Aspire AS5741-H54D/SF battery
Similar to the above test procedure, first to test drive their single SAS I read and write speed. Read and write speeds tested were 150.3MB / S and 140.6MB / S. And PIKE 1068E test scores compared to the results a little behind. Backward compatibility in the performance was not very good, because after all, is an array PIKE 2008 card should be used to measure its performance mainly depends on their doing a variety of arrays and other hardware matches shown, so this data does not describes its performance as PIKE 1068E card, we only can be used as a reference. Acer Aspire AS5741-N32C/KF battery
Throughout the RAID 0 is the transmission speed, PIKE 2008 card the same down to leeward, but not much. Here, further evidence, SAS I drive with PIKE 1068E PIKE 2008 card performance than to play better. The array as a second-generation card PIKE 2008 in the use of generation hard disk, there is no generation with generation of hard disk array card play. Look forward with a second generation SAS hard disk, PIKE 2008 card to maximize its performance. Acer Aspire AS5741-N32D/K battery
Usually you can charge and discharge lithium-ion battery 300-500 times. More suitable for lithium-ion battery is not fully charged, and not suitable for rechargeable battery completely exhausted, so frequent a full charge and discharge should be avoided. Although the lithium-ion batteries have no memory effect, but some lithium-ion batteries have been engineers called the existence of a number of memory problems, because the frequent short battery charging does not take full, the battery's own power detector (usually laptop computer batteries have the device) will not completely filled according to the capacity to adjust. Acer Aspire AS5741-N54E/K battery However, if after charging and discharging every 30 times, to conduct a full charge and discharge, we can solve this problem. The best way is to let the battery has been used when the mobile device can not start to conduct a full charge. If you ignore this, then the same lithium-ion battery capacity will be gradually reduced. Acer Aspire AS5741-N54E/KF battery
Aging of lithium-ion battery is easy to overlook the problem of a user. Lithium-ion battery life is usually 2-3 years, and computing time is from lithium-ion ASUS K53SM Battery production line out from the moment the date. With the oxidation of the battery, the battery's capacity will be gradually reduced. When the battery capacity reduced to a certain point, the battery can no longer continue to be used, although this is still the battery can store a certain amount of power. Acer TravelMate 4370 battery Part of the laptop and cell phone batteries by adding a certain amount of cobalt to solve this problem.

Notebook battery refresh program Lesson
Using the battery refresh program to restore the battery's discharge time
Big brand laptop has a battery refresh programmer, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the distribution for the nickel-metal hydride battery(Ni-Mh) batteries, as usual discharge properly, leading to the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what methods can restore the battery's discharge time? for the above, we can use the IBM has launched a ACER Aspire One 753 Battery refresh program to refresh the batteries, discharge time to recovery, specific methods are as follows . Acer TravelMate 4740G battery (1) the use of AC power to the laptop, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download the IBM provided TP390/390e/390x series laptop battery refresh program. (2) Restart your computer, press F8 to enter boot menu and select safe DOS mode. You may give them such questions, I am also P4 machines, why feel so slowly? Acer TravelMate 4740Z battery The reason is that the hard disk, and now the mainstream notebook hard drive speed is 4200 rev / min, 5400 gradually into the mainstream, and although the hard disk has been around 7200, but the application is minimal. The current minimum is also a desktop computer 7200, and the overall performance hard drive is a very critical constraint of a hardware, so slow to slow in the hard disk. Acer TravelMate 4750 battery
(3) just download the files into the directory, the implementation of the battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation. (4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Message. (5) prompted unplug the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, the system will automatically shut down. Acer TravelMate 5335 battery (6) The ACER Aspire One 753 Battery temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power. (7) boot the computer with a floppy disk, the Autoexec. bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key. ( At this point, refresh process began to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete. (9) Shut down the computer, and charge the battery until the light turns green so far. (10) The above procedure is repeated three times to get the best results. Acer TravelMate 5335G battery
Battery life not by the length of the total use of time, but by the charge and discharge times to decide. If you always to the notebook without the battery installed to take down, even if turned off the machine and remove the AC power after the batteries are not like the thought kept as fully charged state. Acer TravelMate 5335Z battery Notebook batteries because the battery in the integrated control circuit, so even when the power is also shut down the computer power. As an AC power source connected, the battery will start charging, when turned on or off the power when the battery is repeatedly charged and discharged, affecting battery life.
In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Acer TravelMate 5340 battery Because each cell batteries can not be completely consistent with the nature, quality and use for a long time some little worse after the beginning of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader can try to open the DELL Inspiron N4120 Battery pack, the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product. Acer TravelMate 5340G battery

Method of repair laptop battery
Most Laptop manufacturers in the product when leaving the plant are said to buy a new laptop should be in full discharge of the case, repeated three times on the battery fully charge / discharge, charge, preferably more than 14 hours. Acer TravelMate 5542 battery It is so short, so that the notebook computer users had a wrong view. In fact, the laptop products at the factory before the battery will activate, in order to avoid wear and tear affect battery performance, with only a small amount of electrical energy. Since the completion of a laptop battery is fully charged ACER Aspire 1830T Battery, it will automatically stop working, there is no need to maintain the charge time to 12 hours. In general, buy a new laptop just follow the normal charge / discharge method can be activated. Acer TravelMate 5542G battery
At present, most brand laptop recovery disk will only cover the system partition C, even if the partition will be restored to factory default state of a partition will be prompted to give the corresponding options. The Compaq laptop I've seen the recovery disk will be handed does not give any tips in the case resume into a partition. Acer TravelMate 5735 battery So get a new laptop and then be sure to use after the resumption of what the system restore disk to avoid future data storage and more time be thrown off balance.

the notebook ACER Aspire 1830Z Battery can be converted the other system?
Can say that this really is a problem of food at home, do not know why so many users will ask the new laptop. Acer TravelMate 5735Z battery Notebook computer is, it, like desktop computers, the drive can be installed under the premise of supporting any PC operating system.

The Reason of damage battery
When using Laptop battery long time, I am often dissatisfied with electricity charge, and even the battery is damaged, the specific performance is larger resistance, the voltage across the charging up faster. Acer TravelMate 5735ZG battery This easy to charge control circuit judge to have full capacity will naturally decline. As the larger battery internal resistance, discharge voltage drop, high speed, so the system is easy to mistakenly believe that voltage is not enough power is low. Comparison of the discovery of short battery life, should take corresponding measures.
You may give them such questions, I am also P4 machines, why feel so slowly? Acer TravelMate 5740 battery The reason is that the hard disk, and now the mainstream notebook hard drive speed is 4200 rev / min, 5400 gradually into the mainstream, and although the hard disk has been around 7200, but the application is minimal. The current minimum is also a desktop computer 7200, ACER Aspire 1830TZ Battery and the overall performance hard drive is a very critical constraint of a hardware, so slow to slow in the hard disk.
XI, and why some functions with a super-rabbits are ineffective? Acer TravelMate 5740-332G16Mn battery
Super rabbit lot of people will optimize the Masters this desktop optimization of weapons used in conventional laptop on, used, found that many features with the good about failure, such as the brightness of the sound adjustment. The reason is the super rabbit will be the drivers of these features as unnecessary since the launch of the process to the disabled, such as the Hotkey drivers and so on. Acer TravelMate 5740-332G25Mn battery So this kind of optimization procedure used in the notebook even, if you have to optimize as far as possible, after determining which does not require manual optimization.
How to extend laptop battery life?
Laptop battery long time to charge less often, or even show damage, and therefore must use attention to some tips: No matter what your laptop to use nickel-metal hydride or lithium electricity, to power the basic exhaustion as much as possible and then charge (charge less than 5%), which is the best way to avoid the memory effect. Acer TravelMate 5740-333G25Mn battery In fact, the lithium-ion battery has some memory effect, but much smaller than the nickel-metal hydride batteries Bale. But note that charging the battery, try to avoid too long, the general control within 12 hours.

Laptop Battery Maintenance Tips
Laptop Battery Maintenance - 3, after the exhaustion of battery charge and avoid charging time is too long regardless of your notebook to use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is The best way to avoid the memory effect. Acer TravelMate 5740G-334G32Mn battery No memory effect on lithium to say, I had in front of businesses that are irresponsible and misleading. Lithium also has memory effect, but its memory effect smaller than nickel-metal hydride Bale. And battery charging as same as you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery and other precautions mentioned here are limited.
Acer TravelMate 5740G-434G32Mn battery The new battery can improve the deep charge-discharge lithium-ion battery's actual capacity? See related information in the information which can not, I also asked an expert for this, experts say this is meaningless. The first three could not think of all the so-called charge-discharge using the "activate" what is necessary. But after we marked in the deep charge-discharge capacity of why change it?

Notebook computer lithium-ion batteries are generally with management chip and charge control chips. The "management chip" in a series of registers, there is capacity, temperature, ID, charge status, and discharge times and other values. These values are in use will gradually change. "Charge control chips" mainly control the battery charging process. Acer TravelMate 5740G-5452G32Mnss battery Lithium-ion battery charging process is divided into two phases, fast charge constant current phase (the battery indicator light yellow) and constant current decline phase (the battery indicator light flashes green. Constant current fast charge phase, the battery voltage is gradually increased The standard voltage to the SAMSUNG NT-R719 Battery , then under the control of the chip into the constant voltage, the voltage will not rise to ensure that no over-charge, current is increased gradually as the battery level reduced to 0, and the ultimate completion of charging. inside the battery have a statistical power chips, will discharge curve by recording impulse (voltage, current, time) can calculate the sample battery power, this is what we read about in the Battery Information wh. value. Acer TravelMate 5740G-6765 battery The lithium-ion batteries in the repeated use , the discharge curve may change, if the chip has been no opportunity to once again read out a complete discharge curve, the calculated power is not accurate. so it is necessary to calibrate the battery charge-discharge depth of the chip.
