Assume that you use offline files (client-side caching) on a computer that is running Windows Vista or Windows Server 2008. In this situation, the computer may crash when you try to wake the computer from Sleep (S3) mode. Additionally, you receive a Stop error message that resembles the following:

STOP: 0x0000007F (parameter1, parameter2, parameter3, parameter4)
UNEXPECTED_KERNEL_MODE_TRAP

Notes:

• Not all “0x0000007F” Stop errors are caused by this issue.
• Parameters in this Stop error message may vary, depending on the configuration of the computer.
• This issue occurs if no network connection is available when you wake the computer.
• This issue may be more likely to occur if the computer has remembered connections to Distributed File System (DFS) shares that contain offline files.

Consider the following scenario:

• You have a computer that is running Windows Vista Service Pack 2 (SP2) or Windows Server 2008 Service Pack 2 (SP2).
• The computer has a USB device attached.
• You try to resume the computer from sleep.

In this scenario, you receive a Stop error message that resembles the following:

Stop 0x000000FE (00000008, 00000006, 00000001, parameter4)
BUGCODE_USB_DRIVER

Note: The last parameter in the Stop error message may vary, depending on the configuration of the computer.

Consider the following scenario. You have a portable computer that runs Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008. You put the computer to sleep (S3) while the computer’s lid is open. Then, you close the lid while the computer is asleep. Later, you open the lid to wake up the computer.

In this scenario, the computer starts resuming. However, you only see a blank screen and a mouse pointer until you provide some user input. For example, this situation lasts until you press a key or click the mouse.

Note: This problem occurs only on certain computers.

After you resume a Windows Vista-based computer from sleep or from hibernation, you have one or more of the following problems:

• A device crashes or no longer works correctly. There may be a yellow exclamation mark next to the device in Device Manager. Or, the device may not appear in Device Manager. The device may be a fingerprint reader, a Windows Media Center remote control, an optical drive, a FeliCa reader, or some other device.
• After you resume the computer, you use the Safely Remove Hardware option to remove a device on a portable Windows Vista-based computer. However, in this situation, you cannot reconnect the device. After this problem occurs, the computer may crash when you try to shut it down or to restart it.
• When you connect a USB device, you receive a “Stop 0x7e” error message that resembles the following:
  

  STOP 0x1000007E
  usbhub.sys
  SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

• You receive a Stop error message that resembles the following:
  

  STOP 127
  PAGE_NOT_ZERO_NVIDIA_USB

  This error occurs on a Windows Vista-based computer that has 2 gigabytes (GB) or more of RAM and an NVIDIA nForce EHCI controller.

The Poweroff shaped icon in Vista Start menu is getting the system in to Sleep mode instead of shutdown.

When a computer that is running Windows Vista or Windows Server 2008 enters the sleep mode or the hibernate mode, some files are corrupted. In some cases, the computer does not restart.

Consider the following scenario:

• You have a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Vista Service Pack 2 (SP2).
• That computer uses internal eHome Infrared Receiver.
• You resume the computer from hibernation.

In this scenario, a Windows Media Center remote control does not work. Additionally, you cannot find the eHome Infrared Receiver item in Device Manager. Instead, you find an Unknown device under Universal Serial Bus controllers. This issue also occurs when a Windows Vista-based computer changes from standby to hibernation when the hybrid sleep feature is enabled.

On a computer that is running Windows Vista or Windows Server 2008, you receive the following Stop error message when you resume the system from sleep mode:

Stop 0x000000FE (00000008, 00000006, 00000001, parameter4)
BUGCODE_USB_DRIVER

Notes:

• The parameters in this Stop error message may vary, depending on the configuration of your computer. Typically, the first three parameters are 8, 6 and 1. However, the fourth parameter varies.
• The symptoms of the Stop error may vary, depending on your computer’s system failure options. For example, your computer may restart when the Stop error occurs.

After resuming a computer running Windows Vista from sleep (S3) or hibernation (S4), with the monitor powered off, you cannot see a logon screen and will not be able to logon.

If you have a USB Streaming device attached to a computer running that is resuming from a Sleep (S3) or Hibernate (S4) state, the system may halt and you may receive a “Stop 0xFE” error message on a blue screen. This error message resembles the following:

STOP 0x000000FE (00000002, parameter2, parameter3, parameter4)
