thanks for ur input but that key combo does nothing on my machine...

btw, i've solved my sleep/wake issue recently...

what did it for me was:

chameleon2 rc3 bootloader
dsdt patch for usb built-in
"-v" boot flag

now my machine sleeps and wake up fine...

but even now if my machine doesnt boot up with the -v flag... it doesnt wake up...

if i do boot up with the -v flag... it sleeps and wakes everytime...

ive tested this repeatedly many times and the -v is the game changing factor that fixed my wakeup issue...

so try booting with -v and see if it makes any difference on ur machine...
