Compaq Screen Does Not Wake Up After EnergyStar Shutdown

 * }

Q132886

-

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
The following computers are known to exhibit this problem:


 * Compaq Presario 520
 * Compaq Presario 522
 * Compaq Presario 524
 * Compaq Presario 526
 * Compaq Presario 528
 * Compaq Prolinea 466

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.
