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 0×000000FE (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 0×000000FE (00000002, parameter2, parameter3, parameter4)
BUGCODE_USB_DRIVER

A hotfix is available for Windows Vista that addresses excessive power use during sleep or hibernation. This problem presents the following symptoms.

Symptom 1
If you put the computer to sleep or into hibernation when it is running on AC power, the high definition (HD) audio controller continues to use power. Additionally, even after the computer transitions to DC power while the computer is asleep or in hibernation, the HD audio controller still uses power. This behavior persists even though you disable the “Allow this device to wake the computer” option in the HD audio controller properties.

Symptom 2
After you disable the “Allow this device to wake the computer” option in the HD audio controller properties, the Wake on Ring feature still wakes the computer from sleep or hibernation.

Even after you apply hotfix 949514 on the computer, you still experience this problem.

Consider the following scenario:

• You run Windows Vista or Windows Server 2008 on a portable computer that has multiple hybrid graphics processing units (GPUs).
• A GPU mode transition occurs. This usually occurs when you unplug the AC power cord and the computer switches to power saving mode.
• You try to put the computer to sleep or into hibernation.

In this scenario, the computer crashes.

On Windows Vista with the Swedish Language Pack installed, Sleep is incorrectly labeled under the Power Options in the Control Panel. It shows as Vilollage instead of Vila.

Consider the following scenario:

• You have a computer that runs Windows Vista or Windows Server 2008.
• The computer has multiple SATA ports, and the disk controller is configured in the BIOS to operate in IDE mode.
• You have a hard disk attached to a SATA port that is exposed as the device 1 (secondary) port.
• There is no hard disk attached to the device 0 (primary) port of the same channel as the hard drive.

In this scenario, you may experience a delay of several seconds when the computer resumes from sleep. This behavior causes the computer to fail Windows Logo Program requirements for standby resume times.

In Windows Vista or Windows Server 2008, you create a task in Task Scheduler, and then you select the Wake the computer to run this task option. This option makes sure that the computer wakes up from sleep or from hibernation to run the task. In this scenario, the scheduled task wakes up the computer as scheduled. However, 120 seconds later, the operating system resumes sleep or hibernation even if the scheduled task is running. Therefore, the scheduled task is suspended unexpectedly.

Note: The issue does not occur if the scheduled task calls the SetThreadExecutionState() function.

On a Windows Vista SP1-based computer, you have the Feature Pack for Wireless (update 942567) installed. On this computer, after you scan for about 25 Bluetooth devices, you try to put the computer into Sleep (S3) mode. In this scenario, you receive a Stop error message that resembles the following:

STOP: 0×0000007F (0×00000008, parameter2, parameter3, parameter4)
