Hello,
I try to make a list of devices in common laptops what has it's own firmware:
Nice list! Analysing each firmware further could be quite interesting.
Thanks. An important point is: "can the firmware be updated or not".
Some laptops have NFC chips in them, which sometimes requires non-free firmware to work.
Correct, thanks.
I've also heard that the power adapter and battery charger sometimes contains firmware, for charging the battery properly.
It's called the "power management controller", I think.
And maybe memory card readers should be added too?
Good possible that they have firmware. Right.
Smart-card readers probably contain firmware too.
I don't know them in laptops. But maybe some have.
Not strictly part of the laptop, but many laptop docking ports also have non-free firmware in them that can be updated.
Correct, good possible.
Thanks for your help!
With regards, Paul.
