Product(s): Microsoft Windows 95.x Retail Product
Version(s): 95
Operating System(s): 
Keyword(s): win95
Last Modified: 17-DEC-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows 95 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to "wake up" your computer after Advanced Power Management (APM)
has shut down the screen, the screen may remain in sleep mode. To re-activate
the screen you must turn the computer off and back on.

CAUSE
=====

This problem can occur with Compaq computers using the Cirrus Logic 54xxx video
chip set because of a conflict between APM and the computer's BIOS.

RESOLUTION
==========

To resolve this problem, use one of the following methods:

- Do not enable APM in the computer's CMOS settings.

- Do not inform Windows 95 that the monitor is EnergyStar compliant.

- Disable APM in Device Manager in Windows 95.

- Contact Compaq about obtaining a BIOS upgrade.

MORE INFORMATION

- Compaq Presario 520

- Compaq Presario 522

- Compaq Presario 524

NOTE: These computers do not have a flash (programmable) BIOS, so the BIOS
chip(s) must be replaced. To perform this task, please contact Compaq Technical
Support.
