SYMPTOMS
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.





CAUSE
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.



RESOLUTION
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

 * 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.
