If your system was in Suspend mode, it takes a few moments for
the monitor to display and for the hard disk drive to return to
active mode. You'll hear it start again. It takes a few seconds for
the drive to reach its full operating speed and read or write to
the disk.
Note
Some hard disk drives do not support power-saving modes.
Also, the delay caused by the hard disk drive returning to active
mode may cause errors in some applications. If you have
problems, you may want to disable any power-saving features
for the hard disk drive; see "Setting the Green PC Options" in
Appendix B.
Also, the Windows 95 auto-play feature is incompatible with
power management. If you are using Windows 95 and you want
to use power management, disable auto-play.
