Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S1 or S3 state.
PCI PME# Signal Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S1, S3, S4, or S5 state.
PCI Express WAKE# Signal Wake-up Support
When the WAKE# signal on a PCI Express bus add-in card is asserted, the computer
wakes from an ACPI S1, S3, S4, or S5 state.
Wake from PS/2 Devices
PS/2 device activity can wake the computer from an ACPI S1, S3, S4, or S5 state.
When the computer is in the S4 state, any key can be used to wake the computer
provided a supported operating system is installed. When the computer is in the S5
state, the only PS/2 activity that will wake the computer is either the Alt-Print Screen
key combination or the “Power” key that is available on some keyboards. The BIOS
can be used to select between either of the key combinations.
Wake from Serial Port
Serial port activity wakes the computer from an ACPI S1 or S3 state.
