Can I somehow adjust that my laptop starts up when I connect it to the power?
Yes I should be under energy settings to find but I'm not sure
Automatically this will not work, because yes means that he can't retrieve settings. But if you take the battery out, you can only turn it on when it hangs from the power. (If that helps you somehow xD)
Is not it like that a laptop when unfolding starts up. So turn up the power. Or do I somehow do not understand the problem?
As far as I know this is only for a few bios but I think that this is not possible
I would like to follow the Raspberry Pi logic: turn it on, Latop on
No.
This is just a charging cable and does not interest your laptop
