Soldered in the laptop, everything works, thank you!

E**a Jul 08, 2019

Got it. Works. I had to raise from 12 v to 20 v at an output current of about 1.5 a. With this task copes, does not warm in a long mode of operation.

It came in time. Everyone in their sealed bag, but both in a simple puffy mail. Almost crumpled tube, not critical.
