密码保护

注 意 :尽管密码可以为计算机中的数据提供安全保护,但并非万无一失。如果您的数据需要进一步的安全保护,则应该自行采取其它形式的保护措施,例如数据加密程序。

“System Password”( 系统密码)

注 意 :如果您的计算机在无人看管的情况下保持运行状态而又未设定系统密码,或者您没有锁定计算机,从而使他人能够通过更改跳线设置禁用密码,则任何人都可以访问存储在硬 盘驱动器上的数据。

选项设置

如果显示以下两种选项之一,则无法更改系统密码或输入新的系统密码。

“S e t”( 已设置 )— 已设定系统密码。

“Disabled”( 已 禁 用 )— 已通过系统板上的跳线设置禁用系统密码。

仅当显示以下选项时,您才可以设定系统密码:

“Not Set”( 未设置 )— 未设定系统密码,系统板上的密码跳线位于启用位置(默认设置)。

设定 系统密码

要退出该字段而不设定系统密码,请在完成步骤 5 之前随时按 <Esc> 键。

1.进入系统设置程序(请参阅系统设置程序),并验证在“Security”( 安 全 保护)下是否显示了“Unlock Setup”( 解 除设置 程 序锁定 )字段。

2.如果显示了“Unlock Setup”( 解 除设置 程 序锁定 )字段:

a.使用箭头键定位到“Unlock Setup”( 解 除设置 程 序锁定 )字段。

b.按 <Enter> 键进入该字段。

c.键入管理员密码并按 <Enter> 键。

3.使用箭头键定位到“System Password”( 系统密码)字段,然后按 <Enter> 键。

4.“New Password”( 新 密码)字段中键入新密码。

最多可以使用 15 个字符。要在输入密码时删除字符,请按 <Backspace> 键或左箭头键。密码不区分大小写。 某些组合键无效。如果您输入这些组合键,扬声器将会发出哔声。

按下每个字符键(或按空格键键入空格)时,字段中均会显示一个占位符。

5.按 <Enter> 键。

如果新的系统密码少于 15 个字符,则由占位符填充整个字段。

6.要确认密码,请在“Confirm New Password”(确认新 密码)字段中再次键入密码,然后按 <Enter> 键。
