I would like to know if the connection between the two parts (screen
and keyboard) of a laptop "Dell Inspiron" is by wire or radio?

The problem is the following:
The sound is coming into the head-phones but it doesn't come into the
speakers
when I disconnect the head-phones.

Could some one help me? Thank you.
