Disk Time-out
Disk Time-out lets you determine how long your hard-disk drive remains idle before the drive motor turns off
to conserve battery power.
NOTE: This feature does not function with the Advanced Configuration and Power Interface (ACPI).
The AC option is set to Disabled. No user-selectable settings are available for this option. Settings for
Battery option are:
Disabled
15 Seconds
1 Minute
2 Minutes
3 Minutes
4 Minutes 5 Minutes
10 Minutes
15 Minutes
30 Minutes
1 Hour
The default is 3 Minutes if the computer is powered by a battery. To increase battery operating time, set
Disk Time-out to a lower number. However, if your software requires frequent hard-disk drive accesses,
using a higher time-out setting may save battery power and time by minimizing the number of times the
hard-disk drive must power up.
NOTE: Set Disk Time-out to Disabled if using it causes compatibility problems with your software.
A change to the Disk Time-out option takes effect immediately (rebooting is not required).
If you are not in the System Setup program, you can turn off the hard-disk drive immediately by pressing
. The drive resumes normal operation automatically when it is accessed by the microprocessor.
NOTE: Certain key combinations may not function with the Advanced Configuration and Power
Interface (ACPI) or may require configuration with the Power Management Properties window in the
Control Panel. See
