(A) causes damage to the battery

Notebook computer battery a long time, often charge less for electricity, and even shows the laptop battery is damaged, the specific performance of a larger resistance, the voltage across the charging up faster. So easy to charge control circuit is determined to have been filled, the capacity will naturally decline. Since the battery internal resistance is relatively large, the discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that the voltage is not enough, lack of electricity. Comparison of the discovery of short dell inspiron 1320 battery life, should take appropriate measures.

(B) of the battery refresh program restore the battery discharge time

Great brands have a laptop battery refresh program, we can use it to repair the battery. Example: notebook computers, which is equipped with nickel metal hydride battery (Ni-Mh) battery, the usual charge and discharge properly, causing the battery to discharge more and more time is short, less than 5 minutes left, if carrying a laptop to go to work, then it is very inconvenient, what can restore the battery discharge time?

For the above, we can use the dell studio xps 13 battery has launched the official website of the battery refresh refresh program, rehabilitation discharge time, the specific method is as follows.

(1) the use of AC power to the notebook computer, the first official website to download to a laptop refresh program.

(2) Restart computer, press F8 key to enter boot menu and select Safe Mode DOS.

(3) into the directory where the file you just downloaded, perform a dell latitude e4300 battery refresh program, reading the warning message, as required to insert the floppy disk, and then press the Enter key to execute the self-extracting operation.

(4) Boot the computer with this floppy disk, the screen prompted.

(5) follow the prompts to unplug the AC power adapter, 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 start right away, let the battery cool for a while, plug the AC power.

(7) Boot the computer with a floppy disk, the file will automatically run the flash program, and asks the user whether to proceed.

(8) At this point, flash program to start to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete.

(9) Turn off the computer, and recharge the dell inspiron 1545 battery until the light turns green so far.

(10) The above process is 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 damaged the whole (series after) the discharge curve. Interest and ability of readers to try to open the dell mini 10 battery pack, with the help of the multimeter, you can quickly find the damage to the batteries (voltage error). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.
