SATA Power Management – Enables or disables SATA bus and/or device power management. Default is

S5 Maximum Power Savings – Turns off power to all nonessential hardware when system is off to meet
EUP Lot 6 requirement of less than 0.5 Watt power usage. Default is disabled.

power-on. Default is disabled.

Heading
Allows you to set:
●
POST messages (enable/disable). Enabling this feature will cause the system to display POST error
messages, which are error messages displayed on the monitor during the Power On Self Test if the
BIOS encounters some kind of problem while starting the PC. A POST error message will only display
on screen if the computer is capable of booting this far. If the POST detects an error before this
point, a beep code is generated instead. Default is disabled.
●
After Power Loss (off/on/previous state). Default is Power off. Setting this option to:
◦
Power off—causes the computer to remain powered off when power is restored.
◦
Power on—causes the computer to power on automatically as soon as power is restored.
◦
Previous state—causes the computer to power on automatically as soon as power is restored,
if it was on when power was lost.
NOTE: If you turn off power to the computer using the switch on a power strip, you will not be able to
use the suspend/sleep feature or the Remote Management features.
●
POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST process.
This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly
that they are not ready to boot by the time POST is finished. The POST delay also gives you more
time to select F10 to enter Computer (F10) Setup. Default is None.
●
Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.
Allows you to set the computer to turn on automatically at a time you specify.
Allows you to set resources for or disable Legacy devices.
