since two years ago,hp notebook start using three pin adapter,
1.positive,2.ground or 0v,3.ID
what's the ID. the identity of the adapter.
this pin provide information to notebook the adapter is original or non-original.
the early stage the 3 pins notebook accept non-original adapter.
so this the way to modify a 19v adapter to create pin 3.

the old burned adapter.

buy a cheap adapter cut the pin, red is 19v.

use a 47k R.

solded on 19v. n use the old connector head.

but remember!! do not update to the newest firmware. bc newest firmware not accept non-original adapter..
