When the system is suspended in ebook mode, the keyboard keys and trackpad
buttons can easily be pressed by the back of the display. That's
obviously not good when the system is suspended, because it can cause
false wakeups, and even if keyboard wakeup events are disabled, it still
wastes power when the EC has to process those events and flash the LED.
It's not sufficient to have the OS do the work here, because you might
enter ebook mode while the system is already suspended, so the OS wouldn't
get a chance to do anything.
I think the right way to disable the keyboard and touchpad is to send the
"f5" command to both the keyboard and mouse ports. To re-enaable, send
the "f4" command to both ports. I've tried that general approach from OFW
in the Windows suspend/resume path and it behaves the way I think it
should.
