How can I halt my new PC instead of poweroff when I call 'shutdown -H now'?

I want to have the message system halted after command shutdown -H now, but my new PC after this command power-off the machine. With my old PC that command worked fine. But my new PC is powered down after the command shutdown -H now instead of halting with message system halted on screen. What happened? How to return normal behaviour of the shutdown -H now command? OS version is Debian 8.5. Same version of OS is using on both machines, but reactions on shutdown -H now command are different. Could it be settings in BIOS? Could it be a hardware problem?
