unable to use shutdown options

I’ve installed Parrot-kde-security 4.6 lastest release, on a laptop Dell Inspiron 15000, and for some reason I can’t shutdown, reboot, hibernate or suspend my computer correctly, when I try to do it, the screen turn in black, but the power button never gets off, and it sounds that CPU still working.
Do you have an idea how to fix it?

Use

 poweroff

It happens the same thing

Try to boot up via

acpi=off

Other people have had similar issues, try searching the forum for a solution.

It worked for shuting down, but to suspend, or hibernate, it happens the same. And now I can’t watch how many battery left do I have.
