請教: 電腦打不開, 顯示如下英文字System-- is locked, PRESS F1

別人給我一個以前用過的電腦,說是給我可看看新聞和收發E-MAIL,

我打不開,他來幫忙,也忘了怎麽會如此,

特此向熱心人求教:

我開機, 出`來如下這些字後,光標還是停在那裏  閃動:

我重開機 出現如下:

"System-- is locked,

Press F1 for configuration/setup"

我未動,等一會,自動出現如下英文字:

" The RF-ID Tag has changed

  184 Asset control antenna not detected

  System-Security -- Keyboard is locked

  PXE--M04 : Initializing network boot device Using interrupt 18h....

  System--Security -- Keyboard is Unlocked

 176 The system has been tampered with

 Turn power to your system OFF then On

Your system is now locked"

接連的按F1 和不按F1, 開機和關機幾次, 都重複顯示上列英文,

光標還是停在最後一句Your system is now locked那裏  閃動
