SLEEP.SYS 3.1 Required for APM on AST Laptops (83851)

SUMMARY

The advanced power management (APM) icon does not show up in Control Panel on AST APM laptops under Windows version 3.1 unless you use SLEEP.SYS, version 3.1.

According to AST technical support, SLEEP.SYS, version 3.1, is required for APM to function correctly with Windows 3.1. You can download this file in its compressed format (PEXEC386.ZIP) from the AST bulletin board.

If your BIOS version is 1.06 or earlier, you should contact AST for a BIOS upgrade, as this version does not work correctly with SLEEP.SYS version 3.1.

MORE INFORMATION

For more instructions on installing APM for Windows 3.1, please see section 5.0, "Using Advanced Power Management (APM)," in the Windows 3.1 README.WRI file.

In addition, make sure the correct settings are in the SYSTEM.INI file, as follows:

   [386Enh]
   device=vpowerd.386

   [boot]
   drivers=power.drv

NOTE: Windows does NOT set up automatically for APM machines. You must run the maintenance mode of Setup and select one of the APM machines.
