Issuing "halt" command in grub prompt reboots the computer instead of

Is there another command that I should use?

GRUB tries to find out correct ACPI value for power-off and calls ACPI.
It is possible that GRUB fails to parse ACPI tables, it is possible that
ACPI tables are not correct, it is possible that firmware misbehaves.

More debugging is needed; are you willing to install current development
version and assist in debugging?

How can I help?
Assuming of course I am capable.
