It was in the EmbeddedControl region, and they don't specify the \_SB. prefix: Method (_Q50, 0, NotSerialized) { Notify (PWRB, 0x80) } So, it looks like it is specified in the DSDT. I'm not sure why I don't get an event when I press the button. I do get events from the sleep button, but the two are declared somewhat differently. Here they are for comparison: Device (SLPB) { Name (_HID, EisaId ("PNP0C0E")) Method (_STA, 0, NotSerialized) { Return (0x0F) } } Device (PWRB) { Name (_HID, EisaId ("PNP0C0C")) Name (_PRW, Package (0x02) { 0x1D, 0x04 }) } Thanks again, Greg On Mon, 2004-01-19 at 12:34, Greg Sarjeant wrote: > Hi, > > I have another question about my Gateway 200X.
