On a computer that has an ATI 3D RAGE PRO Accelerated Graphics Port (AGP) 2X device installed, when you click Standby on the Start menu to try to put the computer into Standby mode, you may receive the following error message:
The device driver for the ATI 3D RAGE Pro AGP 2X device is preventing the machine from entering standby, please close all applications and try again. If the problem persists, you may need to update this driver.
This behavior may also occur on computers that have an ATI 3D RAGE XL AGP 2X device installed.
This behavior can occur because Windows XP does not provide full power management support for the device driver.
