Comment 5 for bug 220543

This bug is still there. I have installed Ubuntu 14.04 and 16.04 on a Packard Bell v7956 and due to an incompatibility issue I cannot shutdown properly the machine. I have tried really everthing including acpi=force. Sometime it works other it doesn't. I was looking for a workaroud but if I type grub>halt the monitor does not turn off. Any suggestions?
