Hey lehatche,
Sounds like you're not the only one with this issue...
"It is Now Safe to Turn Off Your Computer" error message..."
Peep this...
CAUSE ...
This behavior may occur if one or more of the following conditions are true:
- Your computer supports the Advanced Power Management (APM) feature, but the Advanced Configuration and Power Interface (ACP)-compliant basic input/output system (BIOS) is not configured correctly to permit the operating system to turn off the power supply.
- During an upgrade of the operating system, Windows does not detect that the computer is ACPI-compliant.
- An OEM device driver or service is installed on your computer that is preventing the computer from correctly shutting down.
- Your computer is not ACPI-compliant.
