A method and system for an improved wake mechanism of an information
handling system (IHS) includes an event handler component (EHC) for
handling an event in the IHS. A first device configuration component
(DCC) receives a first input from the EHC. In response to the first
input, it configures a device having a wakeup latency time (WLT) less
than or equal to a predefined transition time. A second DCC receives a
second input from the EHC. In response to the second input, it configures
a device having a WLT greater than the predefined transition time. A time
delay component introduces a predefined time delay in the configuration
of the device having the WLT greater than the predefined transition time.
A control transfer component transfers control between a BIOS and an
operating system of the IHS responsive to the event.
