Turning On Laptop Without Opening Lid

To go anywhere with this, you have to change what closing the lid does and then let other devices wake the computer on movement or keypress by enabling "Allow the device to wake the computer". *Moving this to the System board.

I'm fairly certain you can only come out of hibernation by pressing the power button. It's similar to having the laptop turned completely off. If you can settle for sleep mode, though, then any USB device should be able to wake the laptop (once you've followed Caziel's advice above). My Stealth is hooked up to an eGPU and external monitor, and this is how I "turn it on" (by leaving it in sleep and pressing a key on the USB keyboard).
