laptop battery for a long time, often charge less for electricity, and even shows the laptop's battery is damaged, the specific performance of greater resistance, the voltage at the load faster. As easy to charge control circuit is determined to have been met, the natural ability will decrease. As the internal battery resistance is relatively large, the voltage drop of the discharge when a bigger, faster, so the system is easy to believe, wrongly, that the voltage is not sufficient, the lack of electricity. Comparison of the discovery of short battery life Dell Inspiron 1501, should take appropriate action.
(B) the program to charge the battery up the time of battery discharge
Great brands have a program to charge the laptop battery, you can use to repair the battery. Example: laptops, which is equipped with a rechargeable nickel metal hydride (Ni-MH) battery, the normal load and unload properly, causing the battery to discharge time shorter and shorter, less than 5 minutes remaining , where carrying a laptop to go to work, then it is very uncomfortable, which can restore the download time of the battery?
Therefore, we can use the Dell battery has launched the official website of the program to charge the battery to charge, discharge time of rehabilitation, the specific method is as follows.
(1) the use of AC power to the laptop, the official website to download a program to upgrade the notebook.
(2) Restart your computer, press F8 to enter boot menu and select Safe Mode DOS.
(3) in the directory where the file you just downloaded, make a Dell Latitude dell u4873 battery charging program, reading the warning message, as needed to insert the disk and then press Enter to execute Automatic extraction operation.
(4) Start the computer with this disk, the screen prompted.
(5) follow the instructions to disconnect the AC power adapter, the program automatically downloads the Ni-MH battery, the download is complete, the system automatically shuts down.
(6) The battery temperature is high at this time should not start immediately, let cool for a time, connect the AC power.
(7) Start the computer with a floppy disk, the file will automatically run the flash program, and asks the user to continue.
(8) At this point, the flash program to start charging the battery, the process soon, when the return to DOS A:> when the update is complete.
(9) Turn off the computer and reload the Dell Inspiron 1501 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 base, this phenomenon can not be avoided. Because each cell can not be exactly the same nature, with some lower-grade after the onset of aging, and damaged the (television after) the entire discharge curve. Interest and ability of readers to try to open the dell inspiron 6400 battery pack with a multimeter, you can quickly find the damage to the batteries (voltage error). If conditions permit, in accordance with the corresponding parameters of the batteries can replace the qualified product.
