How to enter Professional Technician mode
Chromebook 3100
Hi. I was normally using my Chromebook the other day - shut it down - turned it back on and right after boot I was presented with a professional technician mode screen. It asked me if I replaced the motherboard recently and bunch of other random questions (it was like a diagnostic tool after changing parts of the system). I asked bunch of communities if anyone knew about this, and no one does. Does anyone know how to access this?

It seems like you've encountered an unexpected diagnostic or technician mode screen on your Chromebook. This is not a common experience for most users. To access or exit this mode, it's best to contact Chromebook or Chrome OS support directly or reach out to the manufacturer's customer support for guidance.
