Are there any videos for the 7390 with the smaller battery (42Wh) versus the larger one?

It would be super helpful if the laptop was named correctly as the "Latitude 7390 2-in-1" and if the title and introduction of this article also named it as such. That is the one shown here and for which ifixit guides exist. The Latitude 7390 is the non-convertible version, its inside is slightly different compared to the one shown here and so far no guides exist as far as I'm aware.
