I tried to get sleep working again today, but no luck. It never really worked on .6 or .7 either. I tried several netkas drivers for my 4850, but all that happens when it goes to sleep is that the screen is turned of, fans and hd still run and usb is turned off to, so I can't "revive" the machine. I wish I could get it to run. I read that a proper DSDT file could help, but here on this forum dsdt appears to be deprecated. Do other people have sleep issues with their DS3L too?
