|"Probably not the answer you want to hear, but sleep mode is not meant for a desktop system it's made for devices like laptops"|
That's news to me, THX 1138. Sleep Mode works fine on my tower PC when I'm going to be away from it for an hour or so. It saves wear and tear on the hard drive and puts the monitor into standby, also reduces electricity consumption.
I doubt many people will agree with you that's it only for laptops, though it's true that conserving battery power applies only to laptops, there's more to Sleep Mode than just that.
