Abstract
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.
