Why did you guys bounce this^^^ back to EE.SE? The question is about stock hardware (or even about software).

@NickAlexeev It's asking why do certain manufacturers do this one thing but others do not, and why don't they all do it. That question is then about the marker, the makers and the reasoning behind what they do. Not in scope for Super User

Pretty much that. It is kinda something unanswerable unless you design laptops for a Living. Also nothing a end user can do about that.

@NickAlexeev I'd say this is opinion-based. It's actually not all that complicated to implement in this charging-control circuitry as modern charging systems are fully electronic. However, it does require extra work to implement and not every manufacturer sees a need to do this.

I would not have migrated this to Electrical Engineering.

The question did wind up getting closed there.

On the contrary. Twas migrated here. I rejected the migration

Not sure why @random decided that migration back to EE was the right call. I didn't think so because it would be closed on both sites.

I would have responded by closing as "primarily opinion-based". It's more a subjective, opinion-based question than a technical question.

It was closed as primarily opinion based and the migration from EE was rejected as a result

... I rejected.

I'm on my way to work so my reaction is a bit slow :

Oh, okay. I guess I had misread the sequence of events here.
