If you're already using microcontrollers, why not emulate a USB keyboard with one, and have an IR sensor that triggers a key press when it gets a signal?

The problem is that when it's asleep a key press won't wake it up. Only pushing the power button or using wake-on-lan will.

One thing I just thought to try is using an app on my phone to send the WOL packet.

Rewire the power button so it's an easy to push switch and put it behind a target. Then your remote can be a nerf gun.

Edit - the other thing that came to mind was to look into HDMI cec and see if there's a setup where turning on your tv will turn on the PC automatically.

Edit 2 - if you go with an app, you could use something like tasker and then you can have different triggers like your phone tapping an nfc sticker (then you don't have to unlock and find an app).

For Windows, maybe this helps. 1. Open Device Manager 2. Find the keyboard under "Keyboards" 3. Right-click and select "Properties" 4. Go to the "Power Management" tab 5. Make sure "Allow this device to wake the computer" is checked

This is probably the cause. It would be highly unusual for any modern motherboard to not support waking from USB HID at all.

I find it unusual you have a device with a keyboard where the keyboard won't wake the computer. You must have some setting disabled for that to happen.

I do this with a USB device that looks like a keyboard, but speaks CEC out the other end. TV turns on with the appropriate source selected, the keyboard sends a wake key.
