>Description:
Power of laptop (Dell Latitude D630 bios A17) with shutdown -h now, does bring this laptop on half halt state because after the message "The operating system has halted." new line appiers with "Please press any key to reboot." and if I press any key laptop reboots.
How is then system halted if it can service the interrupt for the key press to reboot pc.

shutdown -p now and poweroff does correctly poweroff this laptop.

I am not sure if this can have something with BIOS which isn't aligned with allowing halt from the OS.
>How-To-Repeat:
Enter the: shutdown -h now
