I think that your not hanging at all. The machine has resumed fine (you said you can type 'shutdown -p now' and it turns off IIRC), but the LCD hasn't been turned back on so you can't see the screen output is all. My old Dell laptop had the same issue with S3 resume. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
