Default How do I open a Dell AC Adapter?

It hisses with interruptions, like a beep.. and when I press against
the cable with my finger the hissing increases rate and then becomes
constant (no interruptions). The cable gets really hot, but there's no
smell or anything. The led does not come on anymore also. Can it be a
surge protection system?

No, I think you diag'ed correctly in the first place. Likely it's been
damaged beyond easy repair, though. Get another one ASAP.

this fault sounds like bad electrolytic caps, especially if there is
hissing and heat. this may have been brought on by a short in the
cable. either way, given that you may well break the thing by getting
it open I'd start looking for another.
