This parameter allows the hard disk to enter standby mode after
inactivity of 1 to 15 minutes, depending on your setting.  When you
access the hard disk again, allow 3 to 5 seconds (depending on the
hard disk) for the disk to return to normal speed.  Set this parameter to

Off

 if your hard disk does not support this function.

This parameter sets the system to a "fast-on power-saving mode.  It
automatically enters into the standby mode after a specified period of
inactivity.  Any keyboard or mouse action, or any enabled monitored
activities occurring through the IRQ channels resume system
operation.  See section 2.5.2.

This parameter sets the system to the lowest power-saving mode.  It
automatically enters into the suspend mode after a specified period of
inactivity.

In suspend mode, the CPU clock stops.  Any keyboard or mouse
action, or any enabled monitored activities occurring through the IRQ
channels resume system operation.  See section 2.5.2.

The IRQ items under this parameter allow you to monitor system
activities occurring through the IRQ channels to determine whether or
not to enter power-saving mode.

For example, if you assign IRQ 3 to a fax/modem and you set this item
to 

Enabled

, any fax/modem activity wakes up the system from

standby mode.
