If the backlight brightness was changed and the keyboard unplugged and
replugged, the lights would stay off. They should come back to the

override.

With this change the 3.3V rail gets down to 22mA
The backlight and power led will auto turn off when the keyboard
SLEEP# goes low, and will resume when the sleep pin goes high.
For some reason WFI does not sleep as long as I would expect.
Something is triggering interrupts constantly
that we need to figure out to save power.
