The chances of my Alphasmart Neo not working (from the shelter)
and two more devices from Alphasmart (Dana) not working (from this house)
by error, by itself,
is slim to none.
I will return these devices to Amazon.
From there, please use these devices as evidence to meddling.
It needs to be looked into why it's not working.
I don't think it's because of the battery.
I only turned it on briefly few times.
