Method of repair laptop computer batteries
(A) cause damage to the battery

Notebook computer battery life is longer, often dissatisfied with battery Laptop Battery charge, 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 Latitude D505 battery discharge time?

(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 Latitude D510 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 for a while, the 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. 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 Latitude D520 batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product.

5, notebook battery maintenance

1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.

2. At room temperature (20-30 degrees) for the battery of the most suitable working temperature, the temperature is too high or too low operating environment will reduce the battery life.

3. Can provide a stable power supply in the environment using a laptop computer, remove the battery for extended battery life is affected by incorrect. On the Asus notebooks, when the battery fully charged, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.

4. Suggested an average of three months to conduct a Latitude D600 battery power correction action.

5. To minimize the number of battery

The number of battery charge and discharge is directly related to life on one charge, the battery on a step forward to retirement. Suggest that you try to use an external power supply,

6. Use an external power supply when the battery removed.

Some users often several times a day Plug Power, and notebook computers equipped with a battery, to do so, even greater damage to the battery. Because each access to external power supply is equivalent to the battery charge time, battery life shortened by a naturally.

7. Power exhaustion after the charge and avoid charging time is too long

Whether your notebook to use nickel-metal hydride or lithium-electric power, it must take charge after the exhaustion of power (capacity less than 1%), which is the best way to avoid the memory Latitude D610 effect. Lithium-Ion battery memory effect will be the same, but it is the memory effect than nickel-metal hydride smaller Bale.

8. Usually Caution

When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts with metal objects, etc. happen.

On core laptop batteries

Currently laptop battery can be divided into 4 core, 6-cell, 9-pin, 12 cores. In short, four-cell battery life 2 hours, 6-core, compared with 3 hours, and so on. Of course, the greater the number of cores, the longer the life, of course, the higher the price. Ordinary home users recommend the use 312-0068 of four cores, since it is mainly in the home, have a stable power supply. Recommended 6-pin general office users. If there is a higher demand for mobile office, you can consider 9-pin and 12-cell battery.
