When I hang-up the system, then the screem is black. But the power light is brightness. and the disk light is bright sometimes.
When I press any key, the screem is still black. Only can do is to press down power button for several seconds to power off the notebook. Is there the bug of the Centos?

Hard to say. Next time it happens you could try one or more of these steps: --press CTRL-ALT-BACKSPACE and see if you get back to the GUI login screen. if that doesn't work, you could try: --CTRL-ALT-F1 (or F2 or F3) which (if the machine isn't totally dead) should take you to a text mode login screen. if so, you could log in from there and do "shutdown -r now" to reboot the system. --if it is on a LAN and you have another working computer, you could try using SSH to log into it and if successful restart as in the item above. --there are also various recipes for doing a relatively clean shutdown of a non-responsive system involving the "magic sysreq" key. I don't happen to have the details handy, but some googling for that phrase will surely turn up many of them.
Good luck!
Thanks for your reply.

Is this a netbook? I had that problem, until I found out I had to press <fn><fx key with the little lightbulb>

Not netbook, it is a thinkpad notebook.
