ID: Q197477

The information in this article applies to:
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Professional
  • Microsoft Windows 2000 Server

SYMPTOMS

When you attempt to put your computer into Hibernate mode, you may receive the following error message:

The system cannot go to standby mode because the driver <drive>\<device driver name> failed the request to standby.


CAUSE

This behavior can occur if the device driver does not support a sleep level sufficient for hibernation. This can be caused by a number of factors, including out-of-date device drivers or the presence of Microsoft Windows NT 4.0 device drivers in Windows 2000.


RESOLUTION

To resolve this behavior, use one or both of the following methods:

  • Verify that you are using a device driver written for Windows 2000.


  • Verify the device supports hibernation and that you are using the latest device driver.



MORE INFORMATION

Hibernation is a special form of sleep in which the entire system context is paged to a reserved area on the hard disk and is restored when a wakeup event occurs. Not all Advanced Configuration and Power Interface (ACPI) computers support Hibernate mode. On ACPI computers that support hibernation, the following steps occur before the computer hibernates:

  • The ACPI driver checks each device to determine the lowest sleep state supported by that device.


  • The ACPI driver determines each device's lowest sleep state that responds to a wake event. If a wake level is unsupported by a device, the ACPI driver expects the device to send an "undefined" response for that state.


If not every device supports hibernation, the computer cannot go into Hibernate mode. Device drivers that are poorly written or devices that do not properly respond to ACPI queries may still attempt to hibernate. When a device does not respond to ACPI's mode transition request, the error message described earlier occurs.
