 how to start a PC that has been shutdown from a mobile phone from anywhere on the internet? 1. On the PC  Go to Device Manager>Network Adapters Right Click the Network adapter that is connected to LAN and select Properties Go to Power Management tab and check the boxes, Allow this device to wake the computer and Only Allow a magic packet to wake the computer. Go to Advanced tab and ensure Wake on Magic Packet/Wake on Pattern Match are enabled. Note thew MAC address of the PC by going to Start>Settings>Network and Internet>Ethernet>Properties>Physical address (MAC)  2. On the PI Connect a Raspberry PI to the same network that has the PC's that need to be restarted. Enable remote desktop on the pi Install a package in terminal using command sudo apt-get install etherwake Test waking up the PC by using the command : sudo etherwake -i eth0 MAC:ADDRESS Create a script [wol.sh] and make it executable.

  Please do not worry, I am here to help you. The issue can be solved easily. :-) If you are connecting the device with Dolby sound feature(like DVD player, amazon fire stick, Xbox, PS4, etc), please remember to close the "Dolby sound option" of the device(not the projector, just the device you connected), or there will be no sound. The reason is this projector does not support Dolby's Audio decoding due to the copyright of Dolby, so you need to close the Dolby option of the device, you will have the sound. How our customers close the Dolby of the fire stick: setting-->Audio, then select "Dolby Digital plus OFF". For cable box: set the Audio Output of your cable box from "Auto/Dolby" to "PCM" , then reboot it and connect it with the projector, you will have the sound. The Dolby setting must be in the Audio/Dolby settings, it may also be this option "Dolby Digital plus OFF". Link. https://www.amazon.com/ask/questions/TxKHPZRQY7L48
