Thanks guys, i'll give it a go, I can use s1 or s3 but I mainly have bios set to s1 as I think it stops my usb devices turning off.

without usb I can never wake my pc (using usb kb and mouse) ps2 still works.

In vista I set the pc into away mode so it keeps it ready to record tv shows.

which mode would be best in leopard so eyetv can still record my shows, even after sleep or is it not possible?

away mode in vista works if you turn on media sharing and then it will still log out and sleep monitor but keeps pc open for media center extenders and recording.

Hopefully I can find something in leopard that works the same.

Thanks again
