S3 powers off everything (Disks, CPU, fans) but leaves a minimal amount of power to the solid-state no-moveable-parts RAM. S4 writes a bunch of stuff to disks and then powers down just like a normal shut down (S5). You can even take out the battery (I even stripped an old laptop, removed the cpu, disks, heat pipes, fans, and put it all back together on S4 and then resumed). S4 can leave some bios function and power for WOL and other devices, but it's not essential. In fact S5 which every modern ATX computer does STILL leaves power to USB, WOL, modems & keyboards, if required. So when I say 12 day uptimes, this is calculated by the kernel since I last rebooted, not since I last hibernated. I'm not actually running the laptop for 12 days continuously. Although, IMHO, there's no difference to a laptop or desktop in this regard. Push it to the limits I say ;) -- Iain Buchanan serendipity, n.: The process by which human knowledge is advanced.
