[Abdelmonzon]

Hello friends, I am new to the Forum and new to laptops because I only repaired desktop PCs.
I have an hp15-f233wm that gets 19.5 volts and 3.3 volts of ignition, in fact when pressing the ignition button the coils get 1.8v and 1.5 volts but they disappear immediately and come back I would like help please thanks before hand
