The settings are Disabled, Standby, or Suspend. The default settings are Disabled. Hard Disk Timeout (Min) This option specifies the length of a period of hard disk inactivity. When this period expires, the hard disk drive enters the power-conserving mode specified in the Hard Disk Power Down Mode option described on the previous page. The settings are Disabled, 1 Min (minutes), and all one minute intervals up to and including 15 Min. The default settings are Disabled.

If the system is inactive for that period, it will enter from Standby mode to suspend power saving mode.

There are three options: Suspend: Off: The System BIOS will only blank off the screen when disabling video for VGA monitor. In addition to VGA off, BIOS will also turn off the VSYNC & H-SYNC signals from VGA cards to monitor.
