Power Management /APM
Enabled this option is to enable the power management and APM (Advanced Power Management) features.
Video Power Down Mode
This option specifies the power management state that the video subsystem enters after the specified period of
display inactivity has expired.
Hard Disk Power Down Mode
This option specifies the power management states that the hard disk drive enters after the specified period of
display inactivity has expired.
Hard Disk Time Out
This option specifies the length of a period of hard disk inactivity. When this period expired, the hard disk drive
enters the power-conserving mode specified on the <Hard Disk Power Down Mode> option.
Standby Time Out
Suspend Time Out
These options specify the length of the period of system inactivity when the computer is already in Standby mode
before the computer is placed on Suspend mode. In Suspend mode, nearly all power use is curtailed.
Slow Clock Ratio
This option specifies the speed at which the system clock runs in power saving modes. The settings are
expressed as a ratio between the normal clock speed and the power down clock speed.
IRQ
These options enable event monitoring. When the computer is in a power saving mode, activity on the named
interrupt request line is monitored by BIOS. When any activity occurs, the computer enters Full On mode.
