Intel Desktop Board D945GPM Technical Product Specification

⎯ Power continues to the vital components on the system (CPU, memory, and fans, for

example).

• The Intel QRTD off state allows tasks that do not require user input to continue in the

background.

• Works with the Microsoft Away mode to offer a complete power management offering for

ACPI and system standby and hibernate.

• Target resume time is zero to five seconds (about equal to the time it takes for the display to

warm up).

CAUTION

Do not open the computer chassis when it is in the Intel QRTD off state. Opening the chassis in

this state can cause hardware damage.
