Hello!
Today i got a completely and absolutely dead Dell E6540 with burnt FDS6679AZ (PQ4) which i replaced it with a AO4407A.
Now the charger indicates a shortcircuit somewhere and cuts off when i plug it on laptop so i need your help to find it.
I attach photos of the motherboard (before replacement of PQ4) and diagram (PQ4 circuit is on page 60)
Thank you in advace!
