"It Is Now Safe to Turn the Machine Off" Message When You Try to Hibernate Your Computer (298884)


The information in this article applies to:

  • Microsoft Windows XP Home Edition
  • Microsoft Windows XP Professional
This article was previously published under Q298884

SYMPTOMS

When you attempt to hibernate a computer that is running Windows XP, you may receive the following message:
It is now safe to turn the machine off.
When you install Windows XP on a computer that is not in Advanced Configuration and Power Interface (ACPI) mode (by using a standard Hardware Abstraction Layer [HAL]) and you enable the hibernate option, the computer does not turn off (enter an S4 sleep state) as expected.

CAUSE

This behavior most likely occurs on computers that have a standard PC HAL.

RESOLUTION

To resolve this behavior, you can upgrade to an ACPI HAL. However, use caution when you upgrade because there are several factors that determine if a PC is capable of supporting ACPI. Make sure that you back up and verify your data.

STATUS

This behavior is by design.
