The “Lid Closed” State
When the lid is closed (i.e., the “lid closed” state), the notebook suspends its
normally busy tasks to make itself electronically and mechanically more
stable. When the lid is opened, the notebook briefly checks its environment
and always re-initializes devices newly added in or removed from the
notebook.
Though the notebook allows for various hot insertion of peripherals, the “lid
closed” state provides the most stable and practical means to attach and
detach peripheral components.
As a simple rule of thumb, close the lid when adding or
removing peripheral components.
