The PWAK method looks like you should call it on resume and the PWRN method looks like it should be called by a power button handler. However, there already are control method power and sleep buttons in the AML. It looks like CDPW turns on or off power to the CD drive (1 means on, 0 off). GCDP returns the power state of the CD drive. However, most of these functions are hidden in SMI mode so the only way to find out is to try. -Nate
