ZT挽救笔记本锂电池
使用了两年多的东芝笔记本，近来发现电池的使用时间越来越短了，十几分钟就没电了，出门在外做演示真是好不尴尬。另外买一块又有些舍不得那149美元，于是搜索了很多关于锂电池的文章，基本上没有提到修复的方法。再搜索东芝的网站，发现了一个叫Step-Charging（分步充电？）的文章可以部分或完全恢复锂电池的性能。全文如下：
Issue:
Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try "step-charging" the existing battery per the following instructions.
The procedure below is generally useful for charging the batteries in Toshiba notebook computers. Check your User's Guide for more specific information.
Procedure:
Step-charging the computer's battery
1.Unplug the AC adapter from the computer, and turn the computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.
2.Remove the battery pack from the computer.
3.Unplug the AC adapter from the computer.
4.Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.
5.Re-insert the battery pack.
6.Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.
7.With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.
8.Unplug the AC adapter from the computer.
9.Remove the battery.
10.Wait at least 30 seconds, then re-insert the battery.
11.Plug the AC adapter back into the computer.
12.Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.
Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.
Notes:
&S226;It may be helpful to update the compuer's BIOS -- from the Toshiba Support website.
&S226;Click here for the special procedure for the Libretto models.
&S226;If the computer does not turn on at all -- with the AC adapter connected -- the problem is probably not due to a weakened battery.

问题：
电池不能永远可以使用的。任何类型的电池，随着时间的推移都会逐渐失去它们的储电能力。最终，即使笔记本电脑的电池刚刚充满，充电指示器还会显示电池容量少于总容量。电池的使用时间就不会像新的时候那样长了。
当这种情况发生的时候，当然你可以简单地换一块新电池，不过你可能希望试试下面介绍的“分步充电”的方法。
步骤：
1.拔掉笔记本的外部电源，让笔记本使用电池的电能直到它自己关闭。记录这个时间。
2.把电池取下来。
3.拔掉笔记本的外部电源。
4.等待至少30秒。这个时间可以用一块软布擦拭一下电池的触点还有外部电源的插头。
5.把电池装回去。
6.插上外部电源。
7.不用打开笔记本的电源，让它充电直到充满。
8.拔掉外部电源。
9.取下电池。
10.等待至少30秒，再把电池装回去。
11.插上外部电源。
12.再让电池充电直到充满。
重复以上步骤至少三次，每次都比较一下是否电池的持续时间在增加。
注意：
升级BIOS或许会有帮助。
如果笔记本电脑即使使用外部电源也不能开启，问题可能并不是电池造成的。
依照这个方法，我的记录是这样的：
第1次放电大概是剩余电量的85%电脑就自动关闭了。
第2次是70%
第3次是44%
第4次是30%
第5次是28%
第6次是18%
这比以前好多了，可以持续使用一个多小时了。
希望这个方法对其他牌子的笔记本电脑电池也有帮助。

对那些长期不做深放深冲的电池，这个办法还是有效的。以后多注意电池的使用习惯。一个月至少做一次深冲深放的操作，对维护电池性能有好处。但电池老化是不能避免的。

通过楼主这一帖，偶知道了这一秘密
在此致以崇高的敬意
