laptop battery useful tips

Please Pay close attention to the following useful information for your laptops


(A) Reason of damaging battery


After Using the laptop batteries for a long time, you may be dissatisfied with electricity charge, what is worse! The battery is damaged; the specific laptop battery performance is larger resistance, the voltage changes faster. This easy to charge control circuit judge to have full capacity also falls. As the larger battery internal resistance, discharge voltage drop, high speed, so the system is easy to mistakenly believe that voltage is not enough power is low. Comparison of the discovery of short Acer Laptop batteries life, should take corresponding measures.


(B) Refresh program to restore the battery’s discharge time


Big brand laptop has a laptop batteries refresh program, we can use it to repair the laptop battery. For example: a IBMThinkpad390/262650 based laptop, the distribution for the nickel-metal hydride battery (Ni-Mh) batteries, as usual discharge properly, leading to the Asus Laptop batteries discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what methods can restore the Acer Laptop batteries’s discharge time?


In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the batteries, discharge time to recovery, specific methods are as follows.


(1) The use of AC power to the laptop, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download the IBM provided TP390/390e/390x series Acer Laptop batteries refresh program.


(2) Restart your computer, press F8 to enter boot menu and select safe DOS mode.


(3) just download the files into the directory, the implementation of the laptop battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, 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. . . Message.


(5) prompted unplug the AC power, the program will automatically be on the Ni-Mh Asus Laptop batteries discharge, discharge is completed, the system will automatically shut down.


(6) The Fujitsu Laptop batteries temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power.


(7) boot the computer with a floppy disk, the Autoexec. Bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key.


(8) At this point, refresh process began to refresh the Fujitsu Laptop batteries, the process soon, when the return to DOS prompt A:> when that refresh is complete.


(9) Shut down the computer, and charge the battery until the light turns green so far.


(10) The above procedure is repeated three times to get the best results.


In the end , many lithium laptop 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 completely consistent with the nature, quality and use for a long time some little worse after the beginning of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader can try to open the battery pack, the multimeter’s help, you can quickly find the damaged laptop batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.


Hope this information could help you maintain your laptop.
