Bought a new lithium-ion laptop batteries used in the first, to conduct three complete charge and discharge, the battery fully charged at least once a power, then power exhausted, repeated three times before use. To activate the chemicals inside the battery, the electrochemical reaction within the battery into the best state, in the future can be freely used in the charge that is useful, but within a month to ensure that there must be a complete battery discharge, so depth of discharge can stimulate the activation of cell performance, battery life plays a key role. If more than 3 months the battery is not used again until the same should also be carried out with the new battery charge and discharge completely 3 times to make sure to activate the battery.
The use of nickel-metal hydride Dell xps m1330 battery, which must control the charge time should be careful not to frequent over-charging, otherwise it will shorten battery life. In addition, Ni-MH battery should be fully discharged before charging, the charge should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge.
Most users accustomed to using a laptop computer each time, plug the AC power supply, very little battery-powered laptop. In fact, should be at least a month to supply one or two batteries, the battery completely run out, connect the AC full-time. Remember this one, for rechargeable batteries, the battery will run out and then filled with useful and harmless, because the use of lithium-ion hp laptop battery there is a certain inertia effects, for a long time not to use lithium-ion loss of activity, the need reactivated. When the notebook computer using AC in the room when it is best to remove the battery, so it is often a state of charge. Best off when charging laptop, the battery is fully charged, do not unplug the power drop in the charge. Charging is completed, it should be within 30 minutes after use.
In addition, because the vostro 1400 battery is easy to run out of power, but only a majority of laptop batteries, therefore, part of the pen to the computer manufacturers to develop a fast charge feature that lets users run out of power after power with the fastest speed to add . For example, Dell laptops have ExpressCharge feature, you can recharge in one hour more than 90%. Why not 100%? Because, according to Li-ion battery charge and discharge characteristics, if the regular fast charging to 100%, the battery life on the big report shorter, so the back of 10% will be replaced by the slow-fast-charge before the charge to extend battery life.
Without this function for a standard laptop, the best way is to charge off, charge off shorter than start charging more than 30% charge time.
Third, the laptop battery tips
How to make good use of dell laptop battery battery, how to extend their use of time and the life of the other issues, no doubt troubled by the majority of laptop users in the heart of a problem.
(A) to sleep fast
Temporarily using a laptop computer, to save battery power, we can set the power management options, allowing the system to sleep after a period of time, but shorter or longer will have to wait a few minutes, there is no way to make the notebook computer system immediately enter the sleep state?
The notebook computer system to sleep, a quick and easy way is to directly turn off the display. Press display just little things, you can immediately make the laptop sleep, effectively conserve battery power. When you need to re-use, simply open the display, the system will automatically return to the state before the operation.
(B) screen-saving mode
TFT screen is the largest notebook computer power components, in order to reduce the use of the battery when the power it consumes, notebook computer manufacturers of all kinds of devices, but in general are based on the lower screen brightness, and even off-screen method.
In some laptops the power management settings you can customize the brightness of the screen, most laptops can be specific shortcut keys adjust the screen brightness, generally 6 to 8 level brightness adjustment.
(C) energy-saving settings
Desktop using the AC, the computer most people may not attach great importance to energy-saving features, but need to use Universal External battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design more energy-efficient computer hardware, this is not the user to solve the problem. The user can do is set the computer on the effective use of energy-saving options.
Energy-saving setting, there are two require the user to adjust: First, the computer's BIOS setup program on the energy saving mode setting; the most important is in the operating system has many energy-saving settings and operation. In the practical implementation of computer systems, Windows systems should give priority to energy-saving settings in the CMOS settings.
1. BIOS settings in the Energy
In the CMOS settings and large have a "Power Savings", which you can select "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum latitude d630 battery Life" is the default power saving mode setting. Laptop power saving mode in several states, such as Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. These settings on the laptop, able to regulate power consumption, mainly in the computer power state, the timely closure of some facilities without the use of the system. If the wait state, turn off the monitor and hard drive; to sleep, in addition to turning off the display and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system off, once activated, or restart the computer, the desktop return to the exact state before sleep. Energy-saving settings in the CMOS is mainly set by the Idle Mode Standby Mode to enter the Standby Timeout time set by the Standby Mode Suspend Mode to enter the Suspend Timeout time. Phoenix BIOS laptops use the majority. Different BIOS settings may be somewhat different energy, should carefully read the screen prompts.
2. Windows in energy-saving settings
For general users, in the Windows system may operate better understanding of energy management simpler. Windows help file, in the "management of hardware and software" entries, there are two energy-saving notebook computers with the content: "Managing energy consumption" and "use of portable machine" in the "management of portable computer power." Energy-saving settings during Windows, should read these.
In the Windows "Control Panel", click "Power Management", you can open the "Power Management Properties" dialog box. In the "Power Management Properties" dialog box, should be "power scheme" set to "Portable / Laptop" and reasonable arrangements "system waiting for", "Close the Monitor," "Turn off hard disks" option . The computer can manipulate the different options will have some differences, the new factory and the latest computer software will be more operational options, a detailed set of functions should be based on the computer itself and the Windows help file to.
In addition, if your laptop built-in infrared port, when not to ban it, you can extend acer laptop battery life.
(D) alarm settings
Set the battery alarm in time to give prompt the user to save the information. Method is to click open the "Control Panel", double-click "Power" option, click on "alert" menu bar, "Low battery alarm" column for the Windows 98 default 10%, "a serious shortage of battery alarm" column for the Windows 98 default 3% can make the appropriate changes as needed. Click on both the [Alarm Response] button, the "Sound Alarm" and "message" is selected, the "power level" is optional. This is used when the battery alarm limit, a warning window will pop up, and the buzzer alarm will sound to prompt the user to save information in a timely manner. Finally click [OK] button to exit the power management settings.
(E) on energy-saving function
In the "extended HP f2299a laptop battery life technology" section, we have introduced energy-saving feature is a CPU usage of the technology, which allows the performance of laptop computers will play its battery to achieve the best balance between.
Most new models of notebook computers in the BIOS, the CPU energy-saving technologies are given support is enabled by default, if not open as long as the BIOS will support the option to open it OK.
(F) the use of third-party software to monitor battery status
In addition to Windows built-in power management features, there are a lot of utility to monitor battery status. For example, PowerCenter is a power monitoring tool, available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is a service designed for notebook software. PowerCenter not only shows the percentage of battery capacity, but also to show the actual hours and minutes the time available.
There are three kinds of PowerCenter display.
(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the percentage of battery remaining and available time.
(2) CompactDisplay: in use is always displayed at the top of the window.
(3) MinimizeDisplay: PowerCenter reduced to make the Windows taskbar, and the information is relatively simple.
PowerCenter is also attached to a control center, can make up to six kinds of warning. When the battery - down to a certain extent, timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally run out of battery
Regularly run out of battery, in order to ensure a full charge. If you need to completely run out of battery power, which would be: In the Power Management dialog box, select the Battery Drain this particular power mode, all of its three Running on Batteries options are set to Never, this laptop is the computer on will continue to run. Select the mode, then enter the Alarms tab, cancel the Low Battery and Critical Battery Warning check box check mark (so that when Dell inspiron 1410 ac adapter battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run some of the computational complexity of the 3D demo program, which will soon run out of battery power remaining, of course, these disposal Do not forget to unplug the AC the plug.
(H) How to calibrate battery
To enable the battery to achieve the best performance, certain models of notebook computer provides a battery calibration feature, the first time using the battery, this feature can be used to calibrate the battery. Power calibration procedure will be exhausted, and then re-charged, which would enable the correct Windows battery meter to monitor inspiron 1545 battery status. Calibrate the battery as follows.
(1) into the power adapter.
(2) Restart the computer, start screen appears, press F2 to enter BIOS setup.
(3) in the BIOS, select the Exit item, and select BatteryAuto-Learning option.
(4) Press Enter, select BatteryAuto-Learning option (it will appear in front of a "√").
(5) Select the Exit project SaveandExit option to save your settings and exit the BIOS Setup.
(6) The system will reboot and start battery calibration.
(I) how to test battery-powered time
Mastered how to make the longer the battery can supply, many laptop users are also very much like to master the battery performance and understanding of their batteries in the end how much time to work, so as not to appear when the batteries need to use it, "strike" situation. But how can a proper understanding of their own battery time? We can use BatteryMark4.0.1 software to test the dell xps m1710 charger battery life.
, Methods of laptop battery repair
(A) cause damage to the battery
Laptop battery a long time, I am often dissatisfied with battery charge, and even show the battery is damaged, specific performance is larger resistance in the charging voltage rises faster at both ends. So easy to determine the charge control circuit has been filled, the capacity falls. Since relatively large battery internal resistance, discharge voltage drop, high speed, so the system is not easily mistaken for voltage, low battery. In that relatively short battery life, should take appropriate measures.
(B) the battery refresh program to restore the battery discharge time
Big brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the Sony vaio vgn-cr140e battery with a nickel-metal hydride (Ni-Mh) batteries, as usual charge and discharge properly, causing the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what can restore the battery discharge time?
For the above, we can use the IBM has launched a battery refresh program to refresh the battery to discharge recovery time, specifically as follows.
(1) the use of AC power to the notebook computer, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe to download IBM provides TP390/390e/390x series laptop battery for Dell XPS M1330 refresh program.
(2) Restart your computer, press F8 to enter boot menu, and select safe DOS mode.
(3) into the directory where the file you just downloaded, perform a battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to execute the self-extracting operations.
(4) Boot the computer with this floppy disk, the screen StartingPC-DOS. . . Prompt information.
(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, the discharge is completed, the system will automatically shut down.
(6) The battery temperature is high at this time, should not immediately start, let the battery cool for a while, plug the AC power.
(7) Boot the computer with a floppy disk, the Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes and press Enter.
(8) At this point, the program began to refresh the battery for Lenovo IdeaPad Y550A refresh, the process soon, when the returns to the DOS prompt A:> when that refresh is complete.
(9) Turn off the computer and charge the battery until the light turns green so far.
(10) The above procedure was repeated three times to get the best results.
In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be exactly the same nature, with some slightly lower quality long after the beginning of aging, and destroyed the whole (the series after) the discharge curve. Interest and ability of the reader can try to open the battery pack, with the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of replacement Lenovo 92P1213 AC Adapter batteries can be qualified product.
