Windows: Sleep Mode and 32-Bit Disk Access

Last reviewed: November 21, 1994

The information in this article applies to:

Microsoft Windows operating system versions 3.1, 3.11

SUMMARY

Most machines that have a sleep mode cannot effectively use 32-bit disk access. This is true whether the machine implements a "full sleep mode" or a sleep mode that affects only the hard disk. All sleep modes turn off the hard disk as a minimum, and turning off the hard disk effectively disables the functionality of 32-bit disk access.

MORE INFORMATION

There are a small number of machines on which 32-bit disk access can be enabled even though they have a hard disk sleep mode. This feature is machine specific; you must contact your computer manufacturer to verify whether or not your machine has this feature.

The Microsoft Windows User's Guide states the following:

   CAUTION: Using 32-bit disk access may be unreliable on some
   battery-powered portable computers when the computer's power-saving
   features are enabled.
