14.9 Sleep Trap through SMI#
This sample code provides an SMI# routine to develop some software workarounds or debugging
functions before the system goes into ACPI sleep state.
14.9.1 Enable Sleep SMI# in ACPI ASL code
The following example implements Sleep SMI Control Register enable by the ASL code _PTS
method.
Method(_PTS, 1) {
Store(One, \_SB.PCI0.SMBS.SLPS)
PTS(Arg0)
Store(0, Index(WAKP,0)) // Clear Wake up package.
Store(0, Index(WAKP,1)) // Clear Wake up package.
