When the answer is missing

And when the sources don't hold the answer?

TechBuddy answers only from your data. When the documentation doesn't contain the answer, it says so, instead of offering a guess that could send a technician the wrong way.

What is the bolt torque for the X200 model?

TechBuddy's answer

I couldn't find this value in the available documentation, so I won't estimate it. I recommend checking with the manufacturer. If you add the value to the knowledge base, I'll find it next time.
