笔记本电池保养（Laptop battery maintenance）

笔记本电池保养（Laptop battery maintenance） 笔记本电池保养(Laptop battery maintenance) The charge and discharge of the battery is limited by frequency, If you do not usually use the battery down on it. Switch machine charging and discharging will do. The battery has a charging life. The frequency has no use. As long as there is a power supply, it is better to take the battery down. Usually use the battery and then charge it again. So the battery life is longer. It can also be used longer Don't plug in batteries when you plug in the power Full use can be taken down, little impact Notebook battery life is very short, filled thousands of times will not work Notebook battery usage and maintenance Speaking from the battery materials, the use of notebook computer battery is mainly divided into three types: 1. battery, 2. nickel chromium and nickel metal hydride batteries, 3. lithium batteries; they are generally expressed as: NI-CD, NI-MH, lithium nickel metal hydride nickel cadmium LI. 1. activate the new battery It is a new laptop battery manufacturer General in the first boot with 3% of the electricity, at this time, should not use external power supply, but the battery remaining electricity exhausted until the shutdown, and then use the external power supply charge. Then you need to recharge the battery before you recharge it. Charge time must be more than 12 hours. Do it again and again three times to activate the battery. 2. minimize the number of batteries you use The charge and discharge times of the battery are directly related to the service life, and each time the battery is charged, the battery advances to the decommissioning process. We recommend that you use the external power supply as much as possible. When you use the external power supply, you should remove the battery. If the battery is plugged in many times a day, and the laptop is equipped with batteries, it is more damaging to the battery. Because every time the external power supply access is equivalent to a single battery charge, battery life is a natural. 3. recharge the battery and avoid charging too long No matter the use of notebook lithium or nickel metal hydride electric power, must be exhausted after the charge (charge less than 1%), this is the best way to avoid the memory effect. Lithium also have memory effect, but its memory effect was much smaller than the Ni MH battery, only to completely finish for it. Partial charge and discharge may result in inconsistent chemical properties of the cores in the battery, and consequently the performance of the battery will be reduced. It is recommended to conduct a deep battery discharge every few months to optimize the battery performance. The specific thing is to use a battery powered, and always use the battery capacity of 0% (when the system will automatically enter the sleep or standby state, according to the different settings in BIOS). Then connect the AC charger until it's full until 100%. In the IBM laptop battery use, activation and other operations, due to various reasons, often in the details of the operation of the error, unwittingly unwittingly hurt your battery. Let's take two examples in detail to illustrate the importance of "operational details". Example 1: when the AC power supply is in the notebook, when should the AC plug be pulled out after the shutdown? The work is completed after the shutdown, while screen off, at this time it is easy to think of success has been shut down, immediately unplug the AC plug conveniently, knowing the screen while closed, but the motherboard power indicator lamp (indicator lamp in a circle with Z word like) is still burning, in fact this notebook is still working, that is to say this machine is the power supply; if unplug the AC plug, the laptop will be immediately from the AC power supply to the battery for a few seconds, the use of batteries, although such as if with not much power, but accelerate the initial battery quickly dropped to set the charging power value, so as to shorten the battery charge with the cycle, affect the service life of the battery. The AC plug has not been pulled early. How about that time? When the lights go out after the motherboard power (the power indicator is lit), if not unplug the AC plug, the interface circuit consists of a battery management chip program and battery power management system in about 5 seconds will be automatically transferred to the "charge off state", so after the shutdown has not unplug the AC plug no reason to charge >96% battery charging for a short time, and hurt your battery. [the battery is not fully depleted (i.e., the battery is at 5~100%). Do not charge the battery, or it will shorten the battery life. ] Above all, the correct method of operation is: in addition to the power indicator, all lights extinguished after the bottom of the screen, with unplug the AC plug (not later than 5 seconds), the AC plug pulled out after about 5 seconds, the power indicator goes out automatically. According to the above analysis, originally the use of AC power supply, its intention is to minimize the use of the battery, thereby prolonging the battery charging cycle; and because of defects in details, "love unfinished recoiled Qing"; "the importance of the remarkable details of the operation". Example two: when using AC power supply, The AC adaptor input plug and the DC output plug are inserted and unloaded in order of operation details. The correct method of operation is: first the DC output plug the AC adapter into the power jack of the notebook, and then the AC input plug into 220V AC power supply; and the unloading should first unplug the AC input, then the DC output plug. If the plug (discharging) when the reverse order of the AC adapter is at no-load state, the AC adapter is not allowed at no-load state, because of its work on the pulse condition, no-load switching in the transformer winding will produce high inverse peak voltage and breakdown voltage such as IC, capacitors and other sensitive components. Although the current AC adapter has a no-load protection circuit, but because the design to take into account other problems, the protective effect of the protection circuit is very limited; therefore, when the AC adapter at no-load state may be damaged. From the above analysis, we can understand that, any details in the operation are so important, the slightest bit vague and careless; said a little, careful of this is what we usually speak of science and technology. Therefore, I think it is necessary to some of the battery operating rules text I wrote before the appropriate modification for consolidation; for reference, in order to draw attention to details; also please the teacher criticism and supplement. Because of the limitation of the compilation, it is impossible to make a detailed analysis of the above example in detail below, and please forgive me. Activation processing: The following battery needs to be activated: 1. new batteries just in use. 2. because the battery is not used for a long time, the battery leaves the storage state of the computer, and then the battery is activated again. 3. do not use laptop or battery for a long time, remove from laptop and store it for storage (over two or three months), and then restart the battery. Method for activating treatment of battery: Activating the chemical in the battery and maximizing the performance of the battery requires three cycles of repeated charge and discharge (complete charge, and then complete discharge). The so-called full discharge refers to the normal boot to the battery power to 3% battery (the best time to run out, also can be divided into several times to power, but not too long time interval), then the battery must be immediately shutdown charging for twelve hours. The emphasis here must be to charge the battery, because the battery may even without the use of self discharge, when the battery power consumption to 3%, if not timely to charge the battery self discharge phenomenon is extremely easy to cause the battery over discharge and damage to the battery, and discharge is a big taboo of lithium battery. When the battery is activated, the machine must be turned off when charging. If the machine is waiting, pending and so on, when the green power status indicator is no longer beating when the charge is 3~4 hours, the machine will automatically stop charging the battery, so that the battery can not be fully charged. When the discharge to 3% of the power, the machine will automatically enter the dormant state, at this time should start the machine, in the process of starting the machine, click the screen left bottom button to shut down the machine. If all the details of these operations are well, and your battery quality is no problem, can well activate chemicals within the cell, maximizing the performance of the battery, each battery basic normal use in the future can charge to 100%. Problems should be paid attention to in use: The battery is a consumable, correct, the battery loss depends on how you use the battery operation mode of operation, operation frequency, environment temperature, storage time (the unused battery) etc.. 1. battery charge and discharge is directly related to the service life of the battery, the lithium battery charge and discharge times generally only about 400~600 times, but also improved the product 800 times, one charge the battery to the end point with a step forward. When charging the battery under 85%, the charge will be recorded and the charge will be increased once Therefore, when the battery voltage is greater than the initial set of charging battery management procedures in 96%, and you are all 220V AC power supply, should try to use the AC power supply, reduce battery charging times, to extend the life of the battery. At this point the battery does not have to be removed from the machine because the battery does not charge more than 96% of the battery power when it is switched on. But even so, if you are a long-term use of AC power and rarely use the battery, or will be better advice away from machine up battery, because the notebook runs for a long time the heat will cause some harm to the battery. It should be pointed out that, in this case once the AC power supply power, you have not yet saved data will be lost due to the lack of the support of the battery, the gains and losses, Users have to weigh it up. 2., when the power is 3~5%, should be charged to the battery in time, otherwise the battery's self discharge phenomenon will cause excessive discharge and damage the battery, when charging, the machine can be shutdown, hang up any state, can also use side charge. The charge must be filled at once, otherwise it will damage the battery. This is to avoid the charge for shortening period increases charging times and shorten battery life based on; and not by "memory effect" problem, lithium battery as NiCd and NiMH batteries with "memory characteristics", not "the memory characteristics of lithium battery". Such as charging machine shutdown or hibernation, when the charge to 3~4 hours after the green power status indicator is no longer beating, the consumption has reached 100%, should be the timely removal of AC power plug to prevent over charging of the battery and battery damage. For example, when charging, the machine is waiting, hanging or charging, and when the charge power is 3~4 hours, the green power status indicator no longer beats, the battery will automatically withdraw from the charging state. In the process of charging will be fast charging, then power status indicator light yellow (Chang Liang), charged to a certain value and then transferred to Juan fine current slow charge, then the power indicator lamp color becomes flashing green; has been filled with 100%, turn green (Chang Liang). The charge process of a lithium battery is a constant voltage mode. When the charging begins, the voltage is stabilized and the current is getting smaller. 3. do not charge the battery before it is fully depleted (i.e. 5~100%), otherwise the battery life will be shortened due to shortening charging cycles and increasing charging times. When the battery power is 5~95%, the battery should be used, so the AC adapter will charge the battery. 4. when the battery charge is 96~100% or have been removed from the machine, you can use the AC adapter boot, please put the DC output plug AC power adapter inserted into the machine using the AC power adapter, and then plug into 220V~ AC power supply socket; should DC output plug unplug the AC power plug then remove the AC from the machine power adapter to remove the AC power adapter. Otherwise, it may cause damage to your equipment. Using the AC power adapter, when the AC power plug into the 220V~ socket, and the power indicator on the state machine has not been lit before (Note: in about 5 seconds) please press the power button boot; shutdown or hibernate, in addition to the green power indicator lamp and all other lights are out, please promptly from the 220V~ socket unplug the AC power plug (not later than 5 seconds), the AC power plug after about 5 seconds, the green power status indicator lights; otherwise it will cause the battery charging and battery damage. Because of the shutdown state AC power adapter is still non unloading, interface circuit is composed of power management chip program and battery power management system in about 5 seconds will be automatically transferred to the "shutdown state of charge, charging the battery. (if necessary, unplug the DC output plug of the AC power adapter from the machine, and the battery will not reverse discharge through the AC power adapter) If the work is stopped and the machine is waiting or pending, do not unplug the AC power plug from the 220V~ socket because the machine must remain powered at this time. (it is recommended that you do not keep the machine waiting or pending for a long time to take care of your machine.) Marked by the related technical index data of 5. IBM in the ThinkPad notebook computer in "battery life", is measured in particular manufacturers under the condition of the index can not be achieved, in our normal use conditions such as notebook related information technology refers to the standard of "mark battery time" for 4 hours, we can only in the normal use in battery power supply for about 3.5 hours. If it is a long distance and is still under warranty, please contact IBM immediately. Maintenance and storage 1., if the battery is longer (months), do not take it away from the machine and reserve it. It is recommended that the battery be discharged and charged every half and half months to improve your battery status to increase battery capacity. 2. if the battery is not used for a long time, it should be set to 30~50% after storage, it is recommended to charge the battery about once a year, and its power is set to 30~50%, to prevent excessive discharge and damage the battery. The specific method of setting the battery power to 30~50% is: when the battery power is greater than 50%, the power consumption can be switched to 30~50%. If the power is less than 30%, then boot the power consumption to 3%, recharge to 100%, and then boot to power consumption to 30~50%. 3., do not put the battery in high temperature and cold environment, battery performance will be temporarily reduced. The batteries in the standby and storage states should be placed in lower temperatures. For batteries, the optimum range of temperature is about 10~20 degrees celsius. About the adjustment of charging starting value Set the initial value of the power plug charging, please click the icon in the system tray (when you use the AC boot) or white battery icon (when you use the battery boot / Improve Battery Health/) numerical modify Start charging when below. Don't prolong the charging cycle and deliberately greatly changes the set starting charging battery management procedures in value; because when you take charge with a low initial value (e.g. 80%), while using the AC power adapter with the battery "charge cycle" may take up to three or four months, but if the situation in the use of the battery will have to re activate the process, otherwise the battery status and capacity are poor. This increases charging times and shortens battery life. In addition, the battery needs a discharge and charge arrangement every half and half months, so the charging cycle is more meaningless after the charging start value is low (for example, 80%). Full battery due to the phenomenon of self discharge of electricity fell to 96% generally lasted for about 50 days, and each battery is just about a month and a half to a discharge and charge arrangement, in view of this, we start charging IBM as the default value is 96%, is not without reason. However, with the battery aging, full battery due to self discharge electricity fell to 96% of the time required may be shortened, at this time we have to take charge of the initial value slightly down, just in time for about a month and a half. If you often need to be in the office and equipment at the scene between two run, AC adapter power supply operation in the office, and in site equipment with battery powered operation, advise you to start charging value is set to 6%; this is to avoid the charge cycle increase due to shorter charging times and shorten battery life; and not for take care of the battery and the influence of the advantages of mobile notebook. Please note, this paper discussed the problem of only IBM ThinkPad laptop, the other brand machines in this paper for reference only, because different brands of machine, the battery management system of power management and control procedures and battery, monitoring procedures are not the same.
