Have some process run some "knock" port like trying to ssh to it to get it to wake-on-lan. The kernel is "asleep and cannot wake itself up". Someone/something must interrupt the sleep from "outside" via the BIOS. A different option is to use the power management features of the kernel. Put the processor into low speed state and HDD to spin down. This does not conserve as much power as a suspend-to-ram but may be enough for you. The kernel will spin up the drive and ratchet up the processor speed as and when required. (BIOS does not play a direct role here). The startup is also significantly faster.
