Shutdown, Hibernate and cli shutdown, only reboot the system

[4bgtexas]

After loading of Linux boot and login is fine. None of the above work to shutdown the system. If I press and hold the power button the system will power off..... BUT..... as the power button is released the system boots back up.

Any ideas.... I have followed most suggestions and not found a fix. I do not believe it is an OS problem... seems to me a BIOS problem. There seems to be no setting in the BIOS that will prevent the reboot.
