今天给一个DELL LATITUDE D620的笔记本换键盘。换好之后出现"Invalid configurat ion information - please run SETUP program"这个之后过会就变成"THIS COMPUTER SYSTEM,#6L1232X-595B,IS PROTECTED BY A Passwordauthenticicationsyste.you cannot access the data on this computer without the correct password.
please type in the system or administrator password and press<enter>是什么意思

看英文的意思是与硬盘或系统有关系，你换个硬盘试试
