电脑电池使用方面的维护
1．当无外接电源的情况下，倘若当时的工作状况暂时用不到PCMCIA插槽中的卡片，建议先将卡片移除以延长电池使用时间。
2．室温(22度)为电池最适宜之工作温度，温度过高或过低的操作环境将降低电池的使用时间。
3．在可提供稳定电源的环境下使用笔记本电脑时，将电池移除可延长电池使用寿命。就华硕笔记本电脑而言，当电池电力满充之后，电池中的充电电路会自动关闭，所以不会发生过充的现象。
4．建议平均三个月进行一次电池电力校正的动作。
5．尽量减少使用电池的次数
电池的充放电次数直接关系到寿命，每充一次，电池就向退役前进了一步。建议大家尽量使用外接电源，
6．使用外接电源时应将电池取下（锂电池不在此列）。
有的用户经常在一天中多次插拔电源，且笔记本电脑装有电池，这样做，对电池的损坏更大。因为每次外接电源接入就相当于给电池充电一次，电池自然就折寿了（特指镍氢和镍镉电池，锂电池不存在这种情况）。
7.电量用尽后再充电和避免充电时间过长
您的笔记本使用的是镍氢电池与镍镉电池，一定要将电量用尽后再充(电量低于1%)，这是避免记忆效应的最好方法。
8．平时使用注意事项
在平时使用时要防止曝晒、防止受潮、防止化学液体侵蚀、避免电池触点与金属物接触等情况的发生。
Excel设的密码怎样解除
用 excel的宏破解 法
1，打开需要解除保护的EXCEL工作表；
2，选择工具---宏----录制新宏---输入名字如:aa；
3，停止录制(这样得到一个空宏)；
4，工具---宏----宏,选aa,点编辑按钮；
5，删除窗口中的所有字符(只有几个),替换为下面的内容:(复制吧)；
6，关闭编辑窗口；
7，工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等2分钟,再确定.OK,旧的密码自动提示，工作表也自动解除保护了。
内容如下：==================================================================================

excel表格被设置了密码保护，无法更改，急需破解
实在不行就采用笨办法：先用只读方式打开表格，然后全选复制，再新建表格粘贴。
怎么破解excel的密码保护
您好，方法
1、我新建一个excel文件（.xlsx格式的）来测试破解过程，其它文件可以参考，但最好要备份原来的文件,设置工作表、工作薄为密码保护，保存后。
2、打开电脑上的压缩软件，然后在菜单里选择打开压缩包，进入excel文件所在的目录，按图2所示，找到excel文件，然后打开,
3、下面介绍一下删除工作薄的密码，如下图红色箭头所指的文件，用内部阅读器打开。
4、搜索，打开搜索界面，搜索“workbookProtection”，如下图所示，把该标签的内容全部删除，
5、保存修改到压缩，
6、下面介绍一下删除工作表的密码，如下图红色箭头所指的文件，用内部阅读器打开,打下面的文件。
7、打开后，搜索“sheetProtection ”，删除整个标签的内容，保存到压缩包。
8、关掉压缩包，重新打开那个测试的excel文件，可以看到密码保护已经没有了。
