extracted DSDT , applied all patches i thought were required , compiled with 0 errors / 0 warnings
everything but shutdown works and while it will 'sleep' i never see the indication on the power supply that its doing so - i have to believe the sleep issue is going to fall in line with the same reason i am having trouble with shutdown
this board is called a TP412 and is the stock board for the box ( Dell Precision T3400 )
it utilizes the intel x38 chipset and has the q6660 quad core CPU
i see no errors whats over on boot or through the console to indicate what should be done to address the shutdown problem
attaching both pre-patched and patched ( p1) DSDT's
if anyone has any ideas please sound off -
thanks
