for a long time without the battery should be how to do
A closer look at the internal battery, which is actually several sets of batteries series-parallel circuit, in general, by a single laptop battery battery capacity and voltage constraints required, notebook batteries commonly used in parallel after the first series of approaches to ensure its operating voltage and battery capacity, an analogy, if a nominal 12.5V, 4000MAh notebook batteries are generally composed of this: the first be three single voltage of 4.2V, 2000MAh on batteries in series, to achieve its 12.5V nominal voltage, and then a group composed of the same cell and then parallel circuit, the battery's overall capacity to upgrade to 4000MAh, this battery is commonly referred to the 6CELL battery pack.
The internal and external batteries for notebook computers as well as the power supply has a certain understanding of principles, we will be able to better work in their daily life batteries used in books. Then talk about the author himself for the notebook computer batteries in the use of some experience and recommendations.
First, got a new battery, toshiba pa3534u-1brs battery many users approach is in accordance with business tips in lithium batteries used in the previous three or more of charge 12 hours. In this connection, there are also many online debates, in fact, that for the majority of laptop batteries is not necessary. Why? Businessmen say this was done in order to fully activate the activity of the battery is completely wake-up a new battery. For this reason it sounds very full and credible, but we have not thought about this problem. If, laptop battery manufacturer has not yet been fully activated on the appearance, then this can be said that only a semi-finished products. Can not require each user to activate cells to master the skills, in reality impossible. Thus, in the battery factory has been in full activation of the vendor. How are users 12-hour rechargeable battery is conducive to use? Here I give a negative answer, the current laptop battery has improved power management circuitry and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit state, so a later time is merely a waste of time only. How can I do to activate the activity of the battery? In fact, the vendor for the activation of the battery case in the absence of overload will be a long time the battery charge and discharge. Therefore, the first three charge 12 hours is unnecessary.
In the second, many users use the battery very confused, what should or should not be charged until the battery is fully depleted. In fact, answering this question should be like this, if you can do that is certainly a good thing, but only if you have too much trouble. Of course, I mean talking about here is absolutely not over-discharge, over-discharge is absolutely proven harmful to the battery, it will shorten the battery life. Thus, when a low power consumption when the notebook prompts can be a timely charge. Some merchants have repeatedly declared their lithium batteries no memory effect, this practice is extremely irresponsible. toshiba pa3399u-1bas battery So when you have more power when the battery is not charging for the good, because the memory effect does exist.
Third, for a long time without the battery should be how to do, it is recommended into the 40-50% of the electricity, placed in the cold shade, the following parameters illustrate the problem.
Storage temperature 40% of the charge state of 100% state of charge
(0 degree 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
[40 ¡ã 85% (one year later) 65% (one year later)
60 degrees 75% (one year later) 60% (3 months later)
(Percentage of saturation at the time the relative percentage of the initial value),
Of course, the best to take the battery out every month to use them once, both to ensure the battery a good state of preservation, but also alienating the loss of damage to the battery power completely.
Fourth, the instructions for use in notebook computers in the "Use a month should put a full-charge" approach is necessary. sony vgp-bps5 battery Notebook computer lithium-ion batteries are generally with the management of chip and charge control chips. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values. These values are in use will gradually change. I personally believe that the instructions for use in notebook computers in the "Use a month should put a full-charge" approach to a major role now is to fix these registers where the wrong values, making the battery charge control and the nominal capacity of the battery match the actual situation. So, this kind of work or can not be omitted, after all, a notebook or a finicky high nobility.
Users should take the initiative to request recall of the computers in question
Acer released last week, according to official sources said on September 15, 2009 production of AS3410, AS3810T, AS3810TG, AS3810TZ and AS3810TZGA such as 5 part of the Acer Aspire series of notebook computers in exceptional circumstances will produce components overheating, thus shell deformation and cause the machine to disable the microphone.
Insiders said that consumers should endeavor to safeguard their legitimate rights and interests, sony vgp-bps2c battery there is potential safety problems if you use the above notebook products, users should take the initiative to log on their official website or call the Customer Service Center to learn of the recall-related processes, requiring manufacturers to carry out maintenance on the machine .
Heating problem into a recall of "theme"
With the laptop in the global and domestic market penetration in recent years, increasing number of laptop recalls, and many of them are related to the Chinese market. Among them, many of the recalls, mainly because the problem is the battery, as well as body heat.
Last year, in September, Sony because of its links to parts of the computer and battery short circuit and overheating risks, the potential to cause security problems, sony vgp-bps5a battery the computers in question in the global recall of nearly 44 million units, of which China market of 7.8 million units.
Last year in October, Sony, Dell, Toshiba, Hewlett-Packard announced on joint use of the Sony recall 100,000 laptop batteries battery cell production, which models problems with about 30 models. The reason is the use of the process of laptop battery overheating problems occur, some of them will appear the phenomenon of smoke and fire.
Recall a similar incident in the last two years, after another, among them are the world's largest brand pc manufacturers are also involved in the type and quantity, and a lot of.
Recently, Acer announced the worldwide recall of five laptop computers are being sold, including the Aspire AS3410, AS3810T, AS3810TG, dell kd476 battery AS3810TZ and AS3810TZG. It is understood that the above five products as long as the September 15, 2009 production, there is overheating, the Chinese market is the area in this recall range.
The Acer recall events, so that laptop security issues once again has attracted extensive attention. Insiders pointed out that the notebook market due to fierce competition, manufacturers for the product's price "and then a low-low" to carry out product cost compression, causing the security problem is one of the reasons.
Improve the performance of laptop battery life
Improve the performance of laptop battery life
How to extend laptop battery standby time? In fact, I have been exploring for more energy-efficient laptops to use, but also to the vendor's technical staff consultation. Had an HP engineer told me: laptop battery life is the length of time determined by a variety of factors, the most important thing is the hardware. We all know that laptop hardware have adopted energy-saving design, for example: laptop ac adapter notebook-specific CPU-SPEEDSTEP technology, when using the battery, it can reduce the operating frequency to reduce power consumption, PIII-M is used "DEEPSLEEP deep sleep" designed to achieve energy conservation and other purposes. In addition, as the present popular 443BX, 815EM, 830MP motherboard chipset, ATI MOBILITY graphics chip, laptop-specific memory Dengjun have similar design, voltage and power consumption is much lower than the desktop as much as possible to extend the battery life time.
Notebook battery capacity is also very important, lithium-ion batteries is very good in this regard. However, this also marked according to the battery on the milliamperes (mAh) to determine size. At present, the laptop battery is generally 3100mAh to 4500mAh, there are very few with 6000mAh, and its higher value use of time longer. In addition, asus laptop battery the number of battery packs is also critical to know the laptop battery is constituted by a number of battery packs, and now many products on sale are marked with their number, more than the number of battery packs using a longer time.
However, for those using desktop hardware, notebooks, addressing the issue of power consumption is more difficult to rely on large-capacity battery.
There are also some practical applications Note: After you install the operating system, you should select "laptop" mode, so that the operating system will get more support in energy efficiency. In power management, but also using the "mini laptop" mode. Also, do not use the screen saver to display the closing time set for 3 minutes or so, you know, the notebook LCD screen is also a big power, if not best to let it rest a long time. Turn off hard disks and standby time, but also located within 10 minutes.
Preferably not connected to any peripherals, try not to use the CD-ROM, floppy drive, we recommend the use of notebook that comes with the mouse or the touchpad bar (with the mouse is ... ...), LCD screen brightness should be appropriate to reduce, so that can also reduce some power. "
It seems, in order to extend the battery usage time is also required "careful planning." Is estimated that the nominal battery standby time, the actual notebook manufacturers are measured out by the above method. I also have a practical use in the discovery, cheap laptop batteries that is WIN2000 more energy efficient than WIN98/ME some, in my notebook, for example, without any operation, hard drives and LCD screens do not close the case, the standby time is running WIN2000 2 hours 43 minutes, WINME standby time is 2 hours 31 minutes. This is just a little bit of my feelings, only for your reference
Grasp of how to make the battery power supply can be longer
Grasp of how to make the battery power supply can be longer, many notebook computer users are also very much like to master the battery performance and understand their own batteries in the end how much time to work to avoid when the battery is an urgent need for "strike" situation. But how can we correctly understand their own battery life time? BatteryMark4.0.1 software, you can use to test the battery life.
The repair method of laptop battery
(A) cause damage to the battery
Notebook computer battery life is longer, often dissatisfied with battery charge, toshiba satellite p205 battery and even show the battery has been damaged, concrete expression of the resistance is bigger, at charging voltage is increasing relatively quickly at both ends. So easy to charge control circuit has been judged already been filled, the capacity also falls. Since relatively large battery internal resistance, discharge voltage drop big, fast, so the system is easy to mistakenly believe that voltage is not enough electricity shortage. The discovery of relatively short battery life, should take appropriate measures.
(B) The battery refresh program to restore the battery discharge time
Big-brand notebooks have a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650-based notebook computers, are fitted with nickel-metal hydride batteries (Ni-Mh) batteries, due to normal charge and discharge properly, leading to the battery discharge time is shorter, leaving less than 5 minutes, if the bring notebook computers to work, then it is very inconvenient, what methods can restore the battery discharge time?
In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the battery put it back in discharge time, uniwill 255-3s4400-g1l1 battery specifically as follows.
(1) the use of AC power to the notebook computer, first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download software provided by IBM notebook computer batteries TP390/390e/390x refresh program.
(2) Restart the computer, press F8 key to enter boot menu and select safe DOS mode.
(3) to enter the directory where the file you just downloaded, the implementation of the battery refresh program isbr0lww, exe, reading a warning message, by asking you to insert a floppy disk, 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. . . Tips.
(5) Follow the prompts to unplug the AC power, the program will automatically pairs of Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.
(6) As the battery temperature is higher at this time should not immediately start, let the battery cool after a while, plug in AC power.
(7) to guide the computer with the floppy disk, this Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Acer as07b71 battery Select yes, press the Enter key.
(8) At this point, refresh program began to refresh the battery, the process quickly, when the return to DOS prompt A:> when that refresh has been completed.
(9) Turn off the computer, and recharge the battery until the green indicator light up.
(10) The above procedure repeated three times to get the best results.
Also, many battery pack lithium battery failure is the failure of a power-saving result of the core, this phenomenon can not be avoided. Because each section of the battery core properties can not be fully consistent with some of the quality of somewhat less long after the beginning of aging and the undermining of the whole (series after) the discharge curve. Interest and ability readers can try to open the battery pack, in the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product.
Learning the above common sense, we have laptop batteries have a new understanding of the battery charging time is also a degree of certainty, the laptop battery maintenance also handy.
Here's a few small trick allows you to extend the life of the screen
1, usually to reduce the screen in sunlight exposure possible. Daytime use, as far as possible to lower the curtains to prevent the screen by the sunshine, the temperature is too high, speed up aging.
2, do the routine cleaning work. Everyday use and the laptop are close contact, so that inevitably left on the screen a variety of stains, dell g1947 battery so we have to do a good job cleaning laptop screen, you can use 3m magic cloth, the general removed the dust can be directly , but for more stubborn and gas in Kazakhstan to use the points. Be careful to cut off all power, so as not to leak or water.
3, lower brightness, so that can effectively extend the service life. Grid during the day usually is enough to open 1-2, 2-3 to open the evening like a grid, and then boot, sometimes the default choice, bright screen, in particular, we must remember that tune back.
4, long time to remember to leave off the screen. If you have something to leave, it must remember to turn off the screen, and the shortcut key is Fn + F3, this way, the screen will not be a BAI Liang.
5, should not have hands, a pen and other objects, pointing screen, a price, and easily lead to dead pixels, began to feel sorry too late.
Part III: laptop keyboard and trackpoint maintenance and maintenance of
Because the keyboard is one of the most frequently used components, although many manufacturers are taking into account their durability, dell gd761 battery especially in the structure was fully optimized, but the water droplets to wear stone, a long time the problem came. Is either a key to good used, or that the letters wear no more.
The user when in use should pay attention to the following major points: first, not to temper the keyboard. Seems to us that the keyboard is the biggest killer of your own, many computer users in the crash after the results of their work because of the loss, could not help but hit the keyboard will be a few outlet gas. We remind you that the keyboard keys to do so would play a supportive role with the Soft-caused damage, there will be a long time bombs and could not go on button press issues. The second point is to try not to eat the top of the notebook computers, smoking or drinking to keep the keyboard clean. In particular, too much liquid into the keyboard, is likely to make short-circuit, resulting in hardware damage. We want users to be able to develop a good habit to eat or drink in the time away from the notebook computer, which will minimize the chance of problems occur, to protect the notebook computer purposes. Secondly, we recommend that you can buy a notebook computer keyboard exclusive soft pad, this soft keys above, there are many rugged place, just be able to cover to the notebook's keyboard, both water-proof, dust-proof, but also Anti-wear, and the price is not expensive, the general computer market that is available. In addition, on a regular basis with a clean cloth remove dust inside the bond between the cracks is also very necessary.
For those who have already flooded the keyboard or have no flexibility to the users, we Jiaoninyizhao. First of all, dell inspiron 1000 battery each button laptop can all be scrimping and open. For standard-sized keys, you use one to pull the nails from top to bottom you can pull the energetically open, then will see a rubber mat, shell buttons up but she is not a relationship. Press the bomb button is not up for the user, you can click this rubber hand, if the are neither bounce if you dropped then you can use other less frequently used buttons instead of the rubber pad with it, or go to the secondary market to buy a notebook computer , the price is very cheap, at least you get the pit than the much cheaper. For the keyboard, the user water, you need to water all of that one of the keys to pull the open, after a careful examination, if it is determined there is no leakage into the liquid inside the computer, then for distilled water or tap water, etc. can be dry For beverages, such as Coca-Cola and so on, these beverages will be left behind after the evaporation of water from dry sticky sugar, then we need you to use low concentrations of alcohol to wipe the. To note that when cleaning every corner of the site especially the rubber pad.
