How do you do well in laptop lithium battery maintenance?

When the newly purchased lithium ion battery is used for the first time, it shall be charged and discharged 3 times completely, that is, the battery shall be fully charged for at least one time, and then the battery shall be drained, and then used again after repeated 3 times. To activate the chemicals inside the battery, the inside electrochemical reaction to achieve the best condition, in the later use that can freely charged when you use it. But ensure that the battery must be within one month once completely discharge, so the depth of discharge can stimulate the activation performance of the battery, which plays a key role in battery life. If the battery is not used for more than 3 months, it shall be charged and discharged 3 times completely as the new battery before using again to ensure the activation of the battery.

If use NIMH batteries, to well control the charging time, charging should be careful not to over frequently, otherwise it will shorten the service life of batteries. In addition, nickel metal hydride battery before charging should be completely discharge, also want to fully charge when charging, before and during normal use, also asked to complete three fully charge and discharge.

Most users habit at every time of using notebook computer, insert plug in the ac power supply, seldom used to power a laptop battery. Actually should use batteries to power a at least twice a month, will be completely run out of battery, connected to alternating current (ac) one-time full again. Remember this one, for rechargeable batteries, will power out full again, beneficial and harmless, because laptops use lithium ion battery has certain inertia effect, can make a long time without use lithium ion lose activity, needs to be activated. When laptops in indoor use alternating current (ac) had better take out the battery, lest make its current charging status. Best to close the laptop charge, enables the battery fully charged, don't pull in the middle of the charging power supply. It should be used after 30 minutes of charging.

In addition, because the battery in the battery is easy to run out, most laptop computers and only a battery, therefore, part of the pen to computer manufacturers to develop the function of fast charging, let users can complement with the fastest speed after the battery power. Such as Dell laptop have Express Charge function, can be charging more than 90% in less than an hour. Why not 100%?Because according to the lithium battery Charge and discharge characteristics, if often quick charge to 100%, against big shorten the life of the battery, so the back of the 10% will be faster by before filling to slow filling to extend battery life.

For a regular laptop without this function, the best thing to do is to turn it off charging, charging off than on charging more than 30% of the time.

Laptop batteries use skills

How to use laptop battery, how to extend its use time and life expectancy is undoubtedly a problem that plagues the majority of laptop users.

(1) Quickly enter the sleep state

Temporarily not to use the laptop, to save battery power, we can set the power management solutions, make the system after a period of time to enter a dormant state, but the long or short have to wait a few minutes, is there any way for laptop computer system to enter a dormant state?

Laptop system rapidly enter a dormant state, a simple method is directly to close the screen. Pressing the display is just a little effort, so that the laptop can go to sleep immediately, effectively saving battery energy. When need to use, as long as the open screen, the system will automatically back to the state before the operation.

(2) The power saving mode screen

TFT screen is one of the largest parts, laptop power consumption in order to reduce its consumption when using battery power, the laptop manufacturer all the towers, but in general are used to reduce the screen brightness, even is the way to close the screen.

In the part of the laptop power management Settings you can customize the brightness of the screen, most laptops can be through specific shortcut keys to adjust the brightness of the screen, usually have 6 ~ 8 level of brightness control.

(3) Energy saving Settings

Desktop using alternating current (ac), most people are unlikely to attach great importance to energy-saving features of the computer, but for the need to use notebook computer batteries to power supply, the use of energy-saving features should be taken seriously. How computer hardware is designed to be more energy efficient is not a problem that users have to solve. What the user can do is effectively use the power saving option on the computer settings.

There are two settings for energy saving requiring user adjustment: One is the setting of the power-saving mode in the BIOS setup program of the computer; the most important thing is that there are many energy-saving settings and operations in the operating system. When the microcomputer system is actually executed, the energy saving settings in the Windows system should take precedence over the settings in the CMOS.

1. Energy saving Settings in the BIOS

In the CMOS setup, mostly have a "Power Savings", which can choose "Maximum Battery Life" and "Maximum Performance" and so on more than one option."Maximum Battery Life" energy-saving mode is the default setting. Laptop model there are several kinds of state, such as Idle Mode, Standby Mode standby (wait) mode, idle mode Suspend Mode suspension (sleep) mode. These Settings on laptops, are able to adjust the power consumption, mainly in the computer after enter into the state of energy saving, duly close some don't need to use the system. Such as when a wait state, shut off the display and hard drive; After enter a dormant state, in addition to close monitor and hard drives, the contents of the memory can also be saved to the hard disk, the entire computer system basic maintain close state, once activated or restart the computer, to a resting state before the desktop will be accurate. Energy saving in the CMOS setup, mainly set by Idle Mode into Standby Mode Stand by Time out time, set by Standby Mode into Suspend Mode Suspend Timeout time. Laptops Phoenix BIOS in the majority. Different BIOS energy-saving Settings may be a little different, should read the screen prompts.

2. Energy saving Settings in the Windows

For the average user, in the Windows system for energy conservation management can understand the simple operation. Windows help file, under the entry "management of hardware and software", there are two laptops and energy saving related content: "energy consumption management" and "use the laptop computer" in the "management of portable machine power". Before the energy Windows Settings, should read the content.

In the Windows control panel, click the "power management", you can open the power management properties dialog box. In the power management properties dialog box, should set the "power use plan" to "portable/laptop," wait "" system, reasonable arrangement" closed monitor ", "closed disk" option. Different computers can manipulate options there will be some difference, the new factory and the latest computer software will be operational options, more detailed Settings should be based on the function of the computer itself and the Windows help file.

In addition, if your laptop has an infrared port built in, you can also extend the battery life of your laptop by disabling it when you don't need it.

(4) Alarm Settings

Set the battery alarm functions can be timely to give tips to save the information to the user. Method is to click to open "control panel", double click on the "power" option, "alert" in the menu bar, "insufficient battery alarm" column Windows98 default 10%, Windows98 default "battery shortage alarm" column is 3%, according to the need for appropriate changes. Click the "alarm response" button, the "voice alarm" and "show the message" are selected, "power level" is not selected. In this way, when the battery uses the alarm limit, a warning window will automatically pop up, and the buzzer will sound an alarm to prompt the user to save the information in time.

(5) Open the energy saving function

In the prolonged use of laptop battery technology we have introduced a, energy-saving function is a CPU usage technology, it can make will make laptop performance to achieve the best balance between it and its battery life.

Most of the new models of laptops in the BIOS, helped support energy saving technology of CPU is on by default, if there is no open as long as to enter the BIOS will support options open with respect to OK.

(6) Using a third-party software monitoring the status of the battery

In addition to Windows built-in power management functions, there are many tools to monitor the status of the battery. Power Center is a power tool, for example, can be downloaded for free (http://meMBers.The xoom.Com/TimothyBug/powercenter/index.HTM).Only 800 KB, is a specially designed for notebook computer software services. Power Center besides cell volume percentage, but also to and points according to the actual time is used.

Power Center has 3 display modes.

Full Display: 1, in the open window showed in details, including the use of batteries or an alternating current, the percentage of remaining battery and available time, etc.

2, Compact Display: in use are always on the top of the window display.

3, Minimize Display: Shrinking Power Center to the Windows taskbar makes the information relatively simple.

Power Center also comes with a control center that can make up to 6 warnings. When the battery - drops to a certain level, the user is promptly warned to save the file being processed. In order not to waste power and CPU resources, Power Center automatically detects changes in battery status.

(7) Deliberately using photovoltaic cells

Use a regular battery to ensure full charging. If you need to fully use the power in the battery, in the Power Management dialog box, select the specific power mode Battery Drain, set all three of the Running on Batteries options to Never, so that the notebook will continue to run. Select this mode, then go to the Alarms tab and uncheck the check boxes for the Low Battery and Critical Battery warnings (so that when the battery is low, the machine will not enter the pause state). Next, let the computer to run a large amount of CPU time task, for example, the computer automatically run some computation complex 3 d demonstration program, that will soon be remaining in the battery power, for the treatment of course don't forget to remove the ac plug.

(8) How to calibrate the battery

In order to make the battery can achieve the best performance, some models of laptop provides battery calibration function, the battery for the first time, can use the function of battery calibration. Calibration program will run out of power, and then charged again, this can make Windows the battery meter correctly monitoring battery status. The calibration steps of the battery.

1, insert the power adapter

2, restart your computer, start screen appears, press F2 to enter BIOS application.

3, in the BIOS program, the choice of the Exit project, and select Battery Auto - Learning options.

4, press the Enter key, the selected Battery Auto - Learning options (it will appear in front of a tick).

5, choose Exit Save and Exit option in the project, save your Settings, and Exit the BIOS program.

6, the system will restart, and start the battery calibration.

(9) How to test the battery power supply time

In master how to make a battery to power supply for a longer time, many laptop users are also very want to know the performance of the battery and know your battery exactly how much time to work, so as not to appear in urgent need to use when the battery is "* * * * * *".But how to correctly understand their own battery life? You can use BatteryMark4.0.1 software to test battery life.

Repair laptop batteries

1, the failure reasons of the battery

Laptop batteries use time grew, often with electricity, even shows the battery is damaged, the manifestation is the internal resistance, on both ends of charging voltage rise faster. So easy to determine by charging control circuit has been full of, capacity is natural fall. Since the internal resistance of the battery is relatively large, the voltage drop during discharge is large and the speed is fast, so the system is easy to mistakenly believe that the voltage is insufficient and the power is insufficient. When it is found that the battery working time is relatively short, corresponding measures should be taken.

2, battery refresh program to restore the battery discharge time

Refresh program brand notebook computers have a battery, the battery to make use of it we can repair. For example: a IBMThinkpad390/262650 type notebook computer, the match for the nickel metal hydride batteries (NIMH battery, due to improper charge and discharge at ordinary times, lead to the battery discharge time is more and more short, only less than 5 minutes, if the laptop to go out to work, is very inconvenient, is there any way to restore the battery discharge time?

According to the above situation, we can use the IBM launched by the battery to refresh program to refresh battery, to restore its discharge time, concrete method is as follows.

1, Use AC power to power the laptop, first to ftp://fip.The PC.IBM.Com/pub/PCCBBS/mobiles/isbr01ww.Exe download TP390 provided by the IBM / 390 e / 390 x series laptop battery refresh program.

2, to restart your computer, press F8 key to enter boot menu, and select the security DOS mode.

3, to just download a file directory, execute the battery to refresh program isbr0lww, exe, read the warning message, insert a floppy disk as required, and then press the enter key perform self-extracting operations.

4, using this guide computer floppy disk, and screen appears Starting PC - DOS...Prompt information.

5, remove the ac power according to directions, the program will automatically of NIMH battery discharge, the discharge is completed, the system will automatically shut down.

6, because the battery temperature is higher, should not be turned on immediately and allow the battery to cool for a while after the plug in the ac power.

7, using the floppy disk boot the computer, the Autoexec. Bat file run automatically refresh program, and ask the user whether to proceed with. Select yes, press the return key.

8, at this point, the refresh program began to refresh battery, its process soon, when back to the DOS prompt A: >, refresh the process is complete.

9, turn off the computer, and the batteries are charging, until the lights turn green.

10, above is repeated three times to get the best effect.

In addition, many lithium battery failures are caused by the failure of a certain battery cell in the battery pack, which cannot be avoided. Because the cell properties of each cell are not completely consistent, some of the poor quality begins to age after a long time, and the overall (after series) discharge curve is destroyed. Interested and capable readers can try to open the battery pack, and with the help of the multimeter, you can quickly find the damaged battery (voltage abnormality). If the conditions permit, replace the qualified product according to the corresponding parameters of the battery core.
