How to turn-on/wake-up a laptop without opening the lid?

I use my laptop with 2 external monitors and external keyboard (I use it as a desktop at home), but when I go out I only take the laptop of course.
What bothers me is that I always have to open and close the lid just to press the power buton.
I dont have enough free space in my working area to keep my laptop's lid open, and I dont want to keep it that way either.

Is there a way I can wake-up/turn-on my laptop without opening the lid?

I dont have another computer in my LAN (just my laptop and router) so the wake-on-lan technique wont serve my needs.
Unless.... there would be some kind of device (a simple and small device) that connects to a LAN and sends the magic packet. But such a device would have to have a way to receive a MAC address as input from the user, so I don't think such a device exists at all.


Solution 1:

Check the BIOS if it supports wake-up on USB, then you can wake it up with an external keyboard.
