Power Management

The Power Management menu allows you to configure the system power-management feature.

The following screen shows the Power Management parameters and their default settings:

Power Management

Power Management Mode	[Enabled]
IDE Hard Disk Standby Timer	[Off]
System Sleep Timer	[Off]
Sleep Mode	[----]
Power Switch < 4 sec	[Suspend]
System Wake-up Event
Modem Ring Indicator	[Enabled]

Power Management Mode

This parameter allows you to reduce power consumption. When this parameter is set to Enabled, you can configure the IDE hard disk and system timers. Setting it to Disabled deactivates the power-management feature and its timers.

IDE Hard Disk Standby Timer

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.
