The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
When you enable Advanced Power Management (APM) on a computer running Windows 95, the Windows 95 clock may slow down or stop when the computer switches to suspended mode. However, the system clock continues to keep the correct time and you can reset the Windows 95 clock to the correct time by restarting the computer.

CAUSE
This behavior can occur if either of the following conditions exists:


 * You enabled APM in the computer's CMOS settings after Windows 95 was installed.
 * Your computer's BIOS supports an older version of APM.

RESOLUTION
To resolve this issue, use the appropriate method.

Enabled APM After Installing Windows 95
If you enabled APM in your computer's CMOS settings after installing Windows 95, Windows 95 APM support may not have been installed. Reinstall Windows 95 to install APM support.

To verify that APM support is enabled, follow these steps:


 * 1) In Control Panel, double-click the System icon.
 * 2) On the Device Manager tab, double-click the System Devices branch to expand it.
 * 3) Double-click Advanced Power Management Support.
 * 4) On the Settings tab, verify that the Enable Power Management Support check box is selected.

APM Support Is Installed
If APM support is installed, suspend the computer by clicking the Start button and then clicking Suspend before the computer switches to suspended mode.

Computer's BIOS Supports an Older Version of APM
You may be able to resolve this issue by upgrading the computer's BIOS. Contact the computer's manufacturer for information about a possible BIOS upgrade.
