(A) Subject to damage the battery
After using the laptop batteries for a long time, you may be dissatisfied with electric charge, which is worse! The battery is damaged, the performance of specific laptop battery is higher resistance, the voltage changes faster. This easy to load the control circuit judge to have full capacity also falls. As the internal battery resistance larger, the discharge voltage drop high speed, so that the system is easy to mistakenly believe that stress is not enough energy is low. Comparison of the discovery of short battery life Acer Laptop, take appropriate action.
(B) of the upgrade program to restore the discharge time of battery
Brand laptop has a great program upgrade laptop batteries, we can use to repair the laptop battery. For example, a IBMThinkpad390/262650 based laptop, the distribution of the nickel-metal hydride (Ni-MH), as usual the download correctly, so the download time for the Asus notebook batteries is short, only less than 5 minutes, if you carry a laptop to work, then it is very uncomfortable, what methods can be restored time Acer laptop battery discharge?
In response to these circumstances, we can use IBM has launched a battery of programs to upgrade the battery update, the download time for recovery, specific methods are as follows.
(1) The use of AC power to the laptop, the first ftp://fip. pc. ibm. com / pub / pccbbs / mobile / isbr01ww. exe download IBM provide TP390/390e/390x series Laptop battery update program.
(2) Restart your computer, press F8 to enter boot menu and select Safe Mode DOS.
(3) just download the files in the directory, the application of portable battery isbr0lww program update, exe, reading the warning message, insert the disk as required, then press the Enter key to the execution of the extraction operation.
(4) bootable floppy disk with this computer, the screen StartingPC-DOS. . . Message.
(5) calls disconnecting the AC power, the program automatically in the Ni-Mh batteries Asus download, the download is complete, the system automatically turns off.
(6) The Fujitsu laptop batteries high temperatures at this time, you should not begin immediately after cooling the battery for a while, plug the AC power.

(8) At this point, started the upgrade process to update the Fujitsu laptop batteries, the process soon, when the return to DOS A:> when the update 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 the end, many portable lithium battery pack failure is the result of a failure of energy-saving base, this phenomenon can not be avoided. Because each cell batteries can not be fully consistent with the nature, quality and use for a long time a little worse after the onset of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader may try to open the battery pack, the help of multimeter, you can quickly find the damaged laptop batteries (abnormal voltage). If conditions permit, in accordance with the corresponding parameters of the batteries can replace the qualified product.
We hope this information could help keep your laptop.
