开机时的第一画面过完后就白色屏上提示下面的错误信息:
the device in the system modular bay cannot be identified.it may not be completely inserted or may have some other problem.
please read and complete the following steps in order.

1):press the device completely and firmly into the bay.
2)press the esc key --wait for the system to power down
3)press the power button to retry detecting the device.

更换过内存.硬盘.电池都无效..biost里面去不去....

望各位指个思路.感谢.

重新拔插光驱后，如果能认到光驱，重装系统吧。
