[NTLK] eMate manufacturing menu ?

[Aaron H]

I recently purchased some untested emates from a school district. Of course, most them have the hinge / display cable issue.

After repairing (or at least attempting as much) one, it worked fine. It was in 'student' mode, and I didn't have the password. I did a hard reset (brain wipe), and somehow ended up in "Manufacturing Menu 1.3.4" with some various diagnostic tests.
 
I really don't know if I was holding down a key or something on reboot, but a quick google of eMate Manufacturing Menu doesn't reveal much...any one know how to get into this mode on an emate?

Aaron.
