On my XO1.5 that I got from the peruvian deployment (from the Ministry
of Education), I tested this, and have found there are two "columns" of
keys that don't respond:

F1, 2, w, s, x, <>
and
F8, 8, i, k, ;

It has latinamerican/spanish keyboard.
The right shift key sometimes appears stuck. It is not responding now.
However when within the OS, I'm sure there were other keys as I couldn't
type "l" or "g" keys.

On the XO4 I couldn't figure out how to reach the keyboard self test.
"menu" command in ofw triggers an OS boot selector (linux/android)
instead of the test.

If it helps I believe this may have to do with the fact that we just
moved to the rainforest and have experienced very high temperatures (up
to 40 C) for the past six months.

I can inquire if more people have found this issue at the ministry if
you like.

Regards,
Sebastian
