A Windows Vista-based computer does not resume from sleep mode if you move or click a USB mouse as the computer is entering sleep mode

SYMPTOMS

Consider the following scenario. You have a universal serial bus (USB) mouse connected to a Windows Vista-based computer. You move or click the mouse as the computer is entering sleep mode. Then, after the computer has entered sleep mode, you try to resume the computer by using the mouse or by pressing a key on the keyboard. In this scenario, the computer stops responding (hangs) at a black screen.

CAUSE

This issue occurs because some USB mouse devices do not work correctly with sleep mode in Windows Vista.

To resolve this issue, follow these steps:

1.

Click Start, type device in the Start Search box, and then click Device Manager in the Programs list.

2.

In the User Account Control dialog box, click Continue.

You may experience problems after you resume a Windows Vista-based computer from sleep or from hibernation

SYMPTOMS

You may experience one or more of the following problems after you resume a Windows Vista-based computer from sleep or from hibernation:

•

A device stops responding (hangs) 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 stop responding when you try to shut it down or to perform a restart.

•

A device such as a fingerprint reader is not available for use at the Welcome screen.

•

The LED lights that represent NUM LOCK, CAPS LOCK, and SCROLL LOCK functionality on a universal serial bus (USB) keyboard do not assume their pre-sleep or pre-hibernation status after the computer resumes. Additionally, these lights now remain off, regardless of the status of the corresponding keys.

Note The conditions that these keys set remain as they were when the computer entered sleep or hibernation. These conditions remain as they were regardless of whether the LED lights are on. If you use these keys after you resume the computer from sleep or from hibernation, the LED lights work correctly.

•

You receive an error message that states that a device does not meet the Logo requirements.

•

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

This problem occurs because of a race condition in the Usbhub.sys driver. This condition occurs if a USB device driver tries to enter a selective suspend state when a previously canceled selective suspend request has not yet been fully processed.

•

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 uses 2 gigabytes (GB) or more of RAM and an NVIDIA nForce EHCI controller.

 

WORKAROUND

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this problem, add the FastResumeDisable entry to the Windows registry. To do this, follow these steps.

Note After you add this registry entry, the computer may take longer to resume from sleep or from hibernation.

1.

Click Start, click Run, type regedit, and then click OK.

2.

Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HidUsb

3.

On the Edit menu, point to New, and then click DWORD Value.

4.

Type FastResumeDisable to name the new entry, and then press ENTER.

5.

On the Edit menu, click Modify, and then type 1 in the Value data box.

6.

Exit Registry Editor.
