The Computer Cannot Enter Standby or Hibernate If a Direct3D-Based Screen Saver Is Running

Microsoft has released a new update for Windows XP, which addresses a rather small flaw that may prevent the computer from entering standby or hibernation mode if a Direct3D-based screen saver is running. Despite replacing two DirectX libraries and all the 3D screen savers that have been shipped with Windows XP, this update does also replace the winlogon.exe with an updated build.  Download here.

Problems If Computer Is Set to Standby After 45 or More Minutes

After you set the Power Options profile so that your computer enters Standby mode after 45 or more minutes, your computer may not enter Standby mode after 45 or more minutes.

This problem can occur when your computer is running on AC power and the standby time is set to 45 or more minutes. When your computer is running on AC power and is idle for approximately 30 minutes, the Windows XP Idle Task Scheduler service runs the system maintenance tasks, and it resets the System Idle counter while it is running these tasks.

If you set the system standby time to 45 or more minutes, the Idle Task Scheduler service starts every 30 minutes, and resets the system idle counter. Because of this, your computer cannot enter Standby mode.

A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem.

The English version of this fix should have the following file attributes or later:

Date Time Version Size File name

After you apply this hotfix, the first time you let your computer stay idle (if the time to Standby mode is greater than 15 minutes), Standby mode is delayed by approximately 15 minutes. After you resume from Standby mode, Standby mode works correctly.

Windows XP is designed to automatically complete maintenance tasks to improve performance and reliability. When our computer is on AC power and is idle, Windows XP does not immediately power down your computer, it provides a chance
for system maintenance tasks to run for a few minutes. These system maintenance tasks include disk layout optimization to improve performance (such as for fast boots) and preparing automatic system restore points to increase reliability.

These tasks do not delay the powering down (suspend) of your computer for more than 15 minutes. These tasks won't be run if your computer is running on battery power. Typically, these tasks are completed the first time your computer is left
idle after startup. These tasks ensure that your computer maintains its performance and reliability even after long use.

Standby Mode Is Delayed 30 Seconds By Raspti.sys

On non-legacy and reduced-legacy computers where no parallel port is present, it may take up to 30 seconds to enter Standby mode.  This behavior can occur if you try to enter Standby mode within 30 seconds after coming out of enter Standby mode. The Raspti.sys driver waits 30 seconds to find parallel ports in the computer.  To avoid this behavior, wait at least 30 seconds after coming out of Standby mode before you try to enter Standby mode again.

Unable to Use Power Management Features

When you try to use power management features such as Standby or Hibernate, your computer may not enter the power management state that you choose, and you may experience one or more of the following symptoms:

- Your mouse may stop responding.
- You may be unable to open or use the Power Options tool in Control Panel.
- You may receive the following error message:

The device driver for the device name is preventing the machine from entering Standby or Hibernation. Please close all applications and try again. If the problem persists, you may need to update the driver.

This issue can occur if you are using one or more device drivers that do not implement power management functionality correctly because they are not Plug and Play or power management enabled.

To resolve this issue, contact the manufacturer of the driver to inquire about the availability of a driver that correctly implements power management functionality.

To work around this issue, use any of the following methods:

Uninstall the Driver

You can uninstall the driver that is associated with the device that is specified in the error message. For information about how to do so, view the documentation that is included with the appropriate device.

Quit Any Programs that Interfere with Power Management Functionality

If you can determine which programs interfere with power management functionality, you can quit these programs before you try to use power management features. Note that some third-party programs that are associated with imaging devices (such as scanners and cameras) may be more likely to interfere with power management functionality.

Mouse Is Not Responding

If your mouse is not responding but your keyboard is still functional, restart your computer, and then use either of the preceding methods:

1. Press CTRL+ESC, and then press U.
2. Press the UP ARROW or DOWN ARROW keys one or more times to select Restart, and then press ENTER.

Some Power Management Settings Don't Migrate in Upgrade to XP

In a preinstalled installation of Microsoft Windows 98, standby functionality is available as part of basic power management. After you upgrade the operating system to Windows XP, the "Enable Advanced Power Management" check box is
cleared, which means that the computer is unable to enter standby. To resolve this behavior, you must manually reset the power management settings.

HOW TO: Verify Unsigned Device Drivers in Windows XP

This step-by-step article describes how you can use the Windows XP Signature Verification tool (Sigverif.exe) to find unsigned drivers and verify device drivers in Windows XP. This information can be helpful for troubleshooting
system instability, error messages, boot problems, and so on.

Verify Unsigned Device Drivers

1. Click Start, click Run, type "sigverif" (without the quotation marks), and then click OK.
2. Click Advanced.
3. Click Look for other files that are not digitally signed.
4. In the Look in this folder box, type "x:\Windows\system32\drivers" (without the quotation marks), where x is the letter
    of the drive where Windows XP is installed.
5. On the Logging tab, make sure the Save the file signature verification results to a log file check box is selected, and then
    click OK.
6. Click Start.

NOTE: The log file is named Sigverif.txt, and it is saved in the Windows folder. Third-party drivers that are unsigned are displayed as "Not signed." Use the drivers in this list as your troubleshooting starting point.

Disable Unsigned Device Drivers

A common problem is power management features, and Microsoft requires power management support to certify drivers. Many third-party unsigned drivers lack this support, resulting in power management problems (such as problems going
into or coming out of hibernation and standby).

After you find unsigned drivers, you can disable them by using any of the following methods:

- Disable the device in Device Manager (you may have to click Show hidden devices on the View menu, and then disable the
   device under the Non-Plug and Play Drivers branch).
- Uninstall the software that installed the third-party driver by using the Add/Remove Programs tool in Control Panel.
- Rename the driver in the Winnt\System32\Drivers folder.

Troubleshooting

If you have multiple unsigned drivers, disable them one at a time. If disabling a driver resolves the problem, contact the manufacturer of the third-party system driver for a updated version that is designed to run with Windows XP.

OpenGL Screen Saver Prevents Power Management Standby Mode

When you configure your computer to use an OpenGL screen saver and the System Standby feature in Advanced Power Management (APM), your computer may not start the Standby mode.  This issue can occur if the OpenGL screen saver starts before the time you configured for the Standby mode to start has elapsed.

Cannot Enter Standby with Diamond Multimedia Stealth II G460

After you install Microsoft Windows XP on a computer that uses a Diamond Multimedia Stealth II G460 video adapter, the computer does not enter System Standby mode. If you try to use System Standby mode on a computer that uses this
video adapter, you receive the following error message:

The device driver for the Stealth II G460 device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists you need to update the driver.

This issue occurs because the Diamond Multimedia Stealth II G460 video adapter does not support System Standby mode. You cannot implement Power management reliably on a computer that uses this video adapter.

To resolve this issue, contact the hardware manufacturer, and ask for an update to the Diamond Multimedia Stealth II G460 video adapter that supports System Standby mode in Windows XP.

How to Enable the Wake from Standby Option for a USB Mouse

This describes how to enable the "Wake from standby" option for a Universal Serial Bus (USB) mouse. 

By default, the Power Management feature of USB mouse devices is turned off. This setting is different from classic PS/2 computer functionality. Therefore, to enable the Wake from standby option, you must manually turn on the Power
Management feature for the USB mouse.

To manually enable the Wake from standby option for the USB mouse, start Device Manager, right-click the USB mouse driver, click Properties, and then click to select the "Allow this device to wake the system from standby" check box.

Mouse Resumes Computer from Standby Mode If Option Is Disabled

In Microsoft Windows XP, you can configure Mouse Programming properties so that you can use the mouse to wake the computer from Standby mode. To do so, open the Mouse Programming properties, click Hardware, click Properties, click Power Management, and then click to select the "Allow this device to bring the computer out of standby" check box.

However, in some cases, even if you have not selected this check box, you can still use the mouse to control the Standby
function.  To resolve this issue, contact the hardware manufacturer to obtain an updated BIOS that is compatible with Windows XP.  The third-party products discussed in this article are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.

No HyperTerminal Connection to Remote Computer in Sleep Mode

When you use HyperTerminal to dial in to a computer that has been put into sleep (hibernate) or standby mode, the computer appears to come out of sleep or standby mode, but there seems to be no connection between the computer and the remote dial phone.

This behavior can occur because some computers require a user-generated event to come fully out of sleep or standby mode. Even though the HyperTerminal connection is active, the computer still behaves as if it is in sleep or standby mode.

To resolve this behavior, perform a user action to bring the computer out of sleep or standby mode. For example, move the mouse, or press a key on the keyboard.

System Standby Disconnects Modem Connections

When you place a Windows XP-based computer on standby, any currently connected remote access connections are silently disconnected. You are not prompted to disconnect manually before the computer goes on standby. This applies to any remote access connections, including connections to Internet service providers (ISPs) and private networks.

Windows XP silently disconnects any active connections before entering standby. When the computer resumes from standby, you must manually reconnect any remote access connections before you can use them.

No Hibernate Button Is Present After Clicking Turn off Computer

After you click "Turn off computer" on the Start menu, you may only see the following buttons even though you have enabled hibernation:  "Stand by", Turn Off , Restart

Note: Computers that are on a domain that are using the classic Shut Down menu, do not have these buttons.

This behavior occurs because Windows displays the "Stand by" button instead of the Hibernate button on computers that support standby. To resolve this behavior, after you click "Turn off computer", hold down the SHIFT key to make the "Stand by" button change to Hibernate.

Standby

In standby, the computer slows down and uses less electrical power. Programs continue to run in the background although the computer may appears to be off. The computer "wakes up" when it detects user input. With some computers, you can
press the power button to wake up the computer.

Note: If your computer experiences a power outage during standby, all work that you have not saved is lost because the computer is still running in the background.

Hibernation

Hibernation, which reduces the start time, saves the complete state of the computer and turns off the power. When you resume from hibernation the BIOS performs the typical Power On Self Test (POST), and then reads the hibernation file, Hiberfil.sys, to restore the state of the computer. Everything that was running when you put the computer in hibernation is restored.

Q291559 How to Change the Logon Window and the Shutdown Preferences

Cannot Shut Down, Restart, Log Off, Stand By, or Hibernate

When you try to put your computer into Hibernate or Suspend mode while the system is writing data to a compact disc (CD), the computer may not enter Hibernate or Suspend mode. You may receive the following error message (or a similar one):

The device driver for the '%device name%' device is preventing the machine from entering hibernation/suspend. Please close all applications and try again. If the problem persists, you may need to update this driver.

You receive neither an informational message that the system is writing to a CD nor an error message that offers you the choice of stopping the CD write process or waiting until the process is complete.  This behavior occurs because you cannot put a computer into Hibernate or Suspend mode while the system is writing to a CD.

To work around this behavior, wait until the CD write operation is complete before you try to put the computer into Hibernate or Suspend mode.  Because the computer has already started to enter Hibernate or Suspend mode, some devices may already be turned off. For example, a USB mouse or scanner may be offline until you complete the Hibernate or Suspend process.

UPnP Clients Are Not Detected When the Computer in Standby Mode

If you place your computer in Standby mode, any Universal Plug and Play devices that are connected to the computer cannot be detected.  This behavior can occur because the network adapter is not active and cannot receive the Universal Plug and Play status messages.

Also, the Wake on LAN (WOL, where LAN is the abbreviation for local area network) ability of some network adapters is not activated by Universal Plug and Play device messages. For more information about Universal Plug and Play, refer to the following Microsoft Web sites:

http://www.microsoft.com/hwdev/upnp/

Computer with IBM ScrollPoint Mouse Does Not Enter Standby Mode

On a computer that is equipped with an IBM ScrollPoint mouse, you may not be able to put the computer into Standby mode.

To resolve this behavior, turn off the "Allow this device to bring the computer out of standby" option for the mouse:

1. Click Start on the taskbar, click Control Panel, and then double-click System.
2. Click the Hardware tab, and then click Device Manager.
3. In Device Manager, click the plus sign (+) next to "Mice and other pointing devices", and then double-click the listing for
    the ScrollPoint mouse.
4. In the Properties dialog box for the mouse, click the Power Management tab.
5. Click to clear the "Allow this device to bring the computer out of standby" check box.

HyperTerminal File Transfer Does Not Survive Standby/Hibernation

When you use HyperTerminal to transfer a file from one computer to another, if one or both of the computers enter standby or hibernation, and pass the timeout period, the file transfer does not succeed and you must restart the transfer.

To resolve this problem, prevent Windows from entering standby or hibernation automatically:

1. Click Start, point to Settings, and then click Control Panel.
2. Double-click Power Options.  -OR-
    Double-click "Performance and Maintenance", and then click Power Options.
3. On the Power Schemes tab, set the following two options as shown:

- Set "System standby" to Never.
- Set "System hibernates" to Never.

Similar communication packages are likely to experience the same problem during file transfers.

Scanner Does Not Work After Computer Returns from Standby

When your computer enters Standby or Hibernate mode while you are scanning an image and one or more programs that are associated with your scanner are running, the programs may stop responding (hang), and your scanner may become
inoperable. After you restart your computer, your scanner may appear as a non-functional device in Device Manager, and when you try to use a program that is associated with your scanner, you may receive the following error message:

                          Scanner cannot be found.

This issue can occur if your scanner uses an Independent hardware vendor (IHV) driver that is unable to properly work with power management features.

To resolve this issue, contact the manufacturer of your scanner to inquire about the availability of an updated driver that is able to properly work with power management features.

To work around this issue, turn your scanner off, restart your computer, and then do not let your computer enter Standby or Hibernate mode while you are scanning an image while one or more programs that are associated with your scanner are
running.

Remote Assistance Stopped by Standby/Hibernate/Fast User Switch

An expert may be disconnected from a Remote Assistance session.  This behavior can occur if one of the following conditions occurs:

- Computer enters Standby mode.
- Computer enters Hibernation mode.
- Fast User Switching is enabled, and a new user logs on.
- The Novice closes the Help and Support Center session.
- The Novice clicks the Disconnect button.

To work around this behavior, note that if the Remote Assistance ticket (original invitation) is still valid, the Expert can reconnect to the Novice when the computer comes back from Standby mode, Hibernation mode, or Fast User Switching. However, if the ticket has expired, another Remote Assistance ticket must be generated and sent to the Expert, or the Expert must be invited again.

If you resume your computer from hibernation after you remove the computer from a docking station, the computer may seem to stop responding (hang), and Windows Task Manager may show 100 percent CPU usage until you reboot the computer.

This issue can occur if your computer is docked when it changes from a power-on state to hibernation, and you then remove the computer from the docking station while it is hibernating.

Changes to the hardware configuration while the computer is in hibernation are supported by some laptop computer designs. However, this functionality is not supported by Microsoft. A docked computer and an undocked computer are considered to be two different hardware configurations; changes to the hardware configuration while a computer is in standby or hibernation is not supported.

Please check with your hardware manufacturer to verify if this functionality is supported on your laptop.

Windows XP Stops Responding at the Welcome Screen

When you restart Windows XP and the Welcome screen is displayed, your computer may stop responding: neither the keyboard nor the mouse work. When you restart your computer again using the F8 key, you may receive the following error
message:

System restart has been paused:

Continue with system restart. Delete restoration data and proceed to system boot menu. This problem can occur when your computer enters into the Hibernate mode and accesses a corrupted memory snapshot.

To resolve this problem, select the "Delete restoration data and proceed to system boot menu" option which enables the computer to perform a normal restart, instead of performing the restoration process while the computer is in Hibernate
mode.

The Hibernate mode is a Power Management mode which can store the state of your computer in its primary mass storage device. The Hibernate mode is useful when you leave your computer in Standby mode for an extended period of time.
