The information in this article applies to:


 * Microsoft Windows 95
 * Microsoft Windows 98

SYMPTOMS
You cannot use the advanced power management (APM) features of your AST Ascentia 900N laptop computer with Windows 95.

CAUSE
The Ascentia 900N computer supports APM version 1.1, but the BIOS installed in this computer returns an unexpected value when Windows 95 makes certain function calls. Therefore, the Windows 95 protected-mode APM driver (VPOWERD.VXD) is unable to load and APM support is not provided.

RESOLUTION
To work around this problem, you can configure Windows 95 to use APM version 1.0 instead of version 1.1. To do so, follow these steps:


 * 1) Use the right mouse button to click My Computer, then click Properties on the menu that appears.
 * 2) Click the Device Manager tab.
 * 3) Click Advanced Power Management Support, then click Properties. Note that you may need to expand the System Devices branch of the hardware tree by double-clicking the branch, or by clicking the plus sign (+) to the left of the branch, before you can click Advanced Power Management Support.
 * 4) Click the Settings tab.
 * 5) Click the Force APM 1.0 Mode check box to select it.
 * 6) Click OK.

For information about additional resolutions that will allow you to use APM version 1.1, please contact AST.
