Why is Wake-on-LAN typically disabled on laptops?
Wake on Wireless LAN (WoWLAN) Most laptops do not support Wake-on-LAN for Wi-Fi, officially called Wake on Wireless LAN, or WoWLAN. The reason most wireless network cards don’t support WoL over Wi-Fi is that the magic packet is sent to the network card when it’s in a low power state.

What should I do if my computer won’t turn on?
As a last resort, turn off the computer by holding in the power button for 5-10 seconds, although you will lose any unsaved work by doing this. You should then be able to turn on the computer again.
