22 Configuring Remote Wake-Up Using Dell Client Command Suite
4 USB Wake
The USB Wake Support BIOS feature allows USB device to wake the system from S3 state. When,
 Enabled – USB devices such as USB mouse, USB keyboard, or touchscreen can wake the system
from S3.When enabled, power is supplied to USB ports during the S3 state.
 Disabled – USB devices cannot wake the system from the S3 state.
Note:
 USB Wake Support does not function for the systems that operate on battery power, even if the USB
devices are externally powered. The determining factor is whether the system’s USB ports are
powered and able to detect USB traffic.
 For USB Wake to work, the USB ports must not be in Deep Sleep. If Deep Sleep Control is:
 Disabled – All USB ports can wake up the system from S3, but only the system’s Smart Power
on Connector port can wake up the system from S4 and S5.
 Enabled in S5 only – All ports can wake up the system from S3, but only the system’s Smart
Power on Connector port can wake up the system form S4. No wake support for S5.
 Enabled in S4 and S5 – All ports can wake up the system from S3. Wake from S4 and S5 is
disabled in this case.
