Hello!
I got a Dell E5440 that is completely dead, charger doesn't detect any shortcircuit so remains lit when i plug it on laptop.
No signs of life at all, i only detect some heat on PQ4.
Plus PQ4 has 19v on pins 1,2,3 & 4 and only 1.8v on the other.
I replaced it but no luck, same behavior.
Any help appreciated, thank you in advance!!!
