How to wake up Android from mouse or keyboard

[Jay Smith]

One thing is to root the Android, for sure. Another it should to disable the power saving on the USB subsystem, so the input will be always monitored. Last it might take a small script/program which will work in background an see any activity on the USB port.

* Detect loss and gain of AC power, lid closure, and the press of a
  number of specific buttons (on Asus, IBM, Lenovo, Panasonic, Sony
  and Toshiba laptops).

None of these are ARM architecture
Furthermore it's rather unreliable.

I see nothing can stop the Power Manager from blanking our screens.
The only option is to leave a chromium browser open on the desktop all the time and use ctl/alt/del to open a blanked screen.
We need an engineer to see if there is a solution.

What is it in Chromium that prevents the power manager activating?
