Although officially not supported i managed to use logmein when my computer is in sleep mode. I altered two settings:
1. Enable WakeOnLAN on the appropriate NIC
2. I had to Enable this same feature in the BIOS (i have an onboard NIC)
The only strange thing i have is that i cannot put it back in sleep mode. Somehow when i press sleep mode through logmein my computer locks down and does not enter sleep state. Off course this is not a big thing since it enters sleepmode after a while on it's own.
