unneeded comments or missing text?
There should be a text, of course.

here you are just fixing a misleading comment, yes?
I don't see any dots to dashes substitution but better ask.
The result is LENOVO-20QE000VMC-ThinkPadX1Carbon7th-20QE000VMC. I think that
the dots were replaced by dashes as the field separators during the initial
implementation or so. I just reflect the current state.
