The metal shield is rounding all the charger. It's conected to earth, but has any more function? My guess it is a shield to avoid interferences. What do you think? I'm going to change a cable without earth, what about if I remove this shield? It does not have any heat dissipation function.
And what about the white adhesive that is everywhere? It's like sikaflex or another polymer adhesive, but is aplied with very little care. I don't think heat dissipation is happy with this.
Googling I found a guy reparing a HP laptop charger and I was very impressed because it looks a clone of Lenovo or vice versa

2. If I'd have to guess, it's a damper for the inductors.

That white stuff (like caulk, and harder than silicone) might be placed to prevent a fault/leak/short across condensed moisture. Might, maybe; I am only guessing; I likely am wrong. I noticed it in several power supplies which include that encasing metal shield. I observe, it is usually applied onto circuit components which are tall or near to that metal case. I assume its purpose is electrical isolation/insulation, where air humidity condensate could form.
I opened a new subject talking about this
