When you attempt to put your computer into Hibernate or Standby 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.
This behavior can occur for either of the following reasons:
  • This behavior can occur if the driver for the device is not Advanced Configuration and Power Interface (ACPI) compliant.
  • The device driver does not support a sleeplevel sufficient for hibernation. This can be caused by a number offactors, including out-of-date device drivers or the presence of MicrosoftWindows NT 4.0 device drivers in Windows 2000.
To resolve this behavior, use the appropriate method:
  • If your device is not ACPI compliant, contact your hardware manufacturer to inquire about the availability of a fix for this issue.
  • Verify that you are using a device driver written for Windows 2000.
  • Verify the device supports hibernation and that you are using thelatest device driver.
Hibernation is a special form of sleep in which the entire system contextis paged to a reserved area on the hard disk and is restored when a wakeupevent occurs. Not all Advanced Configuration and Power Interface(ACPI) computers support Hibernate mode. On ACPI computers that supporthibernation, 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 thatresponds to a wake event. If a wake level is unsupported by a device,the ACPI driver expects the device to send an "undefined" response forthat state.
If not every device supports hibernation, the computer cannot go intoHibernate mode. Device drivers that are poorly written or devices that donot properly respond to ACPI queries may still attempt to hibernate. Whena device does not respond to ACPI's mode transition request, the errormessage described earlier occurs.
