No, once the screen is off, there isn't much you can do. I suggest
you do some experiments in console mode, use "snooze -f" (that will
bypass pmud or pbbuttonsd, which tend to cut the backlight early).
Also, did it die on sleep or on wakeup ? That is, did it reach the
sleep state where the led starts "snoring" ?
